离心力场(超重力场) 被用于相间分离,无论在日常生活还是在工业应用上,都已有相当长的历史。但为一项特定的手段用于传质过程的强化,引起工业界的重视是70 年代末出现的“Higee”, 这是英国帝国化学公司的ColinRamshaw 教授领导的新科学小组提出的专利技术。它的诞生最初是由设想用精馏分离去应征美国太空署关于微重力条件下太空实验项目引起的。理论分析表明, 在微重力条件下,由于g →0 ,两相接触过程的动力因素即浮力因子△( ρg ) →0 ,两相不会因为密度差而产生相间流动。而分子间力,如表面张力,将会起主导作用,液体团聚,不得伸展,相间传递失去两相充分接触的前提条件,从而导致相间质量传递效果很差,分离无法进行。反之,“g”越大, △(ρg) 越大,流体相对滑动速度也越大。巨大的剪切应力克服了表面张力,可使液体伸展出巨大的相际接触界面,从而极大地强化传质过程。这一结论导致了 “Higee”(High“g”)的诞生。

70 年代末至80 年代初,英国帝国化学工业公司( ICI) 连续提出被称之为“Higee”的多项专利。利用旋转填料床中产生的强大离心力———超重力,使气、液的流速及填料的比表面积大大提高而不液泛。液体在高分散、高湍动、强混合以及界面急速更新的情况下与气体以极大的相对速度在弯曲孔道中逆向接触,极大地强化了传质过程。传质单元高度降低了1~ 2 个数量级,并且显示出许多传统设备所完全不具备的优点。从而使巨大的塔器变为高度不到2 m 的超重机。因此。超重力技术被认为是强化传递和多相反应过程的一项突破性技术,被誉为“化学工业的晶体管”和“跨世纪的技术”

离心力场(超重力场)被用于相间分离,无论在日常生活还是在工业应用上,都已有相当长的历史。

1925年Myers制作了带有转转动体的锥形截板式蒸馏桂。

1933年,Plackek发明了侧面闭合的螺旋式气液接触装置,液体沿螺旋板由内向外与逆流流动的气体相接触。几年后,该装置又有所改进,使用带有突起的同心圆筒以增加接触时间。

1954年,Chambers开发了附在旋转平扳上的圆环构成的离心吸收器。

1965年,Vivian将一个填料塔固定在大离心机的旋转臂上,以测定离心加速度对传质系数的影响,实验表面:液膜传质系数与加速度的0.41~0.48次方成正比。Vivian是率先利用旋转床进行传质研究的,但没有提出旋转床域超重力这一概念。

1969年,Todd迸行了离心接触器的实验,该接触器由相隔1英寸的12层环状同心筛板组成,在流体流动上,与筛板塔相类似。

首次出现超重力概念是20世纪70年代末出现的“Higee”,并引起工业界的重视,这是英国帝国化学公司的ColinRamshaw教授领导的新科学小组提出的专利技术。

诞生最初是由设想用精馏分离去应征美国太空署关于微重力条件下太空实验项目引起的。1976年,美国太空署征求微重力场实验项目,英国ICI公司(帝国化学公司)的ColinRamshaw教授等做了化工分离单元操作——蒸馏、吸收等过程中微重力场影响效应的研究,发现在零重力的状态下,其——液间的传质是不可能的,气体和液体不能有效地分离,而超重力使液体表面张力的作用相对变得微不足道,液体在巨大的剪切力作用下被拉升或撕裂成微小的液膜、液丝和液滴,产生巨大的相间接粗面积,因此极大地提高了传递速率系数,而且还使气液逆流操作的泛点速率提高,大大增加了设备的生产能力,这些都对分离过程有力。这一研究成果促成了超重力分离技术的诞生。

在1981年ICI公司Ramshaw教授申请了世界上第一个填料式超重力床专利,在之后的几年时间(198l~1983年)连续提出了名为HIGEE(超重力)新技术的多项专利。

超重力技术的出现,对传质过程的强化可以说是一个质的飞跃,20世纪80年代以来,人们开始意识到这项技术在化工领域具有广阔的应用前景。目前世界上许多大的化学公司都在竞相超重力技术(HighGravityTechnology)进行开发研究,并进行了一定的中试或工业化运行。目前已有多个加压、常压、负压装置在运行,包括进行吸收、解吸、萃取、精馏等操作及实验。在工程化方面有一定程度的进展。

英国Newcastle大学、美国CaseWesternReserve大学、美国TexasAustin大学和美国Washington大学在超重力装置的研究开发中处于世界先进水平。

1983年,ICI公司报道了工业规模的HIGEE装装置平行于传统板式塔进行乙醇和异丙醇与苯和环己烷分离,成功运行了累计数千小时的情况,肯定了这一新技术的工程和工艺可行性。

1984年,美国专门从事塔器与塔填料制造,并占有世界重要市场的Glitsch公司于购买了ICI公司的HIGEE专利,并成立了专门的HIGEE研究开发中心,进行了大量研究,并与CaseWesternReserve大学、washington大学(密苏里州)、TaxasAustin州立大学以及专门从事气体处理的Fluor公司及气体研究院(GRI)等建立了合作研究关系。在能源部大力资助下先后耗费了数千万美元对多种系体进行了小试、中试和工业示范装置的科学实验研究,取得了长足的进展。

1985年,美国海岸警卫队建立了第一套用于脱除地下污水挥发组分的超重力装置,从被污染的地下水中分离出苯、甲苯,由含量200ppb和500ppb脱除到1ppb左右,该装置成功运行了6年。

1987年,美国FlourDaniel公司在新墨西哥州的ELPaso天然气公司建立了利用二乙醇胺对含有H2S和CO2的天然气进行选择吸收H2S的超重力装置。

1987年7月,Glitsch公司在路易斯安那州进行了在不含H2S的气体中利用二乙醇胺吸收CO2和用三甘醇进行天然气干燥两项实验,并都获得了成功。

1989年Glitsch公司宣称,购买一台HIGEE装置可代替50英尺塔高,相当于30块塔板,是用于对传统塔改造,提高产品质量的最经济有效途径。

CaseWesternReserve大学的N.C.Gardner教授从1984年开始,先后在Norton公司,Dow公司支持下对烟气脱硫和聚和物脱单体进行研究。

Martin与Martelli使用旋转填料床(RotatingPackedBed,或RPB)与传统蒸馏塔连接,采用网状金属填充物,对环己烷和正庚烷分离系统进行测试。

郝靖国在CaseWesternReserve大学Gardener教授的指导下进行了旋转填料床脱除聚苯乙烯中残留单体的研究。

英国Newcastle大学的ColinRamshaw教授领导的小组,多年一直致力于海水脱氧的研究。

DowChemical公司于1999年开发了以旋转填料床制备次氯酸的工艺。

另外,国外对超重力技术的应用研究主要在下述方面:(1)蒸馏、精馏;(2)环保中的除尘、除雾,烟气中SO2及有害气体的去除,液——液分离,液_固分离;(3)吸收,对天然气的干燥、脱碳、脱硫,对CO2的吸收;(4)解吸,从受污染的地下水中吹出芳烃、化学热(吸收解吸);(5)旋转电化学反应器及燃料电池(快速去除气泡,降低超电压);(6)旋转聚合反应器;(7)旋转盘换热器、蒸发器;(8)聚合物脱除挥发物;(9)生物氧化反应过程的强化,(传统的生化反应在发酵罐中进行)

国内对于超重力技术的应用研究起步相对较晚,但也取得了显著的成果,主要应用在油田注水脱氧、制备纳米材料、强化除尘过程、强化生化反应过程和精馏等方面。在1985年以前对超重力工程技术研究基本属于空白。

1983年汪家鼎院士就在国内化学工程会议上介绍了ICI所开发的这项新技术的情况。

1984年,北京化工大学与美国CaseWesternReserve大学就超重力工程技术的研究丌发确定了合作意向

1988年北京化工大学郑冲教授与美国CaseWesternReserve大学合作,开始进行旋转填料床的应用。得到化工部和国家科委的高度重视和大力支持,经论证,被列为国家八九年度和“八五”重点科技攻关项目,也得到了中国自然科学基金委对这项高新技术的基础研究的支持。

1990年在北京化工大学建成我国第一个超重力工程技术研究中心并开展了一系列的创新性研究工作,多年来,在超重力技术的基础和应用研究方面取得了多项国家专利。同时国内其它如浙江工业大学、华南理工大学、天津大学等高校也对该技术相继进行了开发研究,并取得了显著的成效。

2001年浙江工业大学计建炳等教授申请了名为折流式超重力场旋转床装置的专利,于2004年11月份得到授权。在超重力工程技术在精馏方面的应用推向了一个新的高度;而后浙江工业大学逐渐申请了数个发明专利和实用新型专利。

而后国内市场出现了多家生产超重力精馏机的公司。

高技术一词的是怎么提出的

  高技术一词最初是英语High Technology直译来的。一般认为,是指建立在综合科学技术研究的基础上,处于当代科学技术前沿,对发展生产力、促进社会文明、增强国防实力起先导作用的知识、技术和投资密集的技术群。高技术是一个动态的概念,随着时间的推移,高技术的主要内容和涉及范围都会有所改变,新的高技术将陆续出现,一些发展成熟的技术也会变为—般技术。 军用高技术是高技术的重要组成部分,是诸多高技术中为了满足国防现代化需要、能够产生新武器系统、作战指挥系统与作战方法而发展起来的那部分新技术群。高技术武器装备是以—种或多种军用高技术为基础研制而成的武器装备,是军用高技术的物化成果,包括开发型武器系统,研制新—代武器装备和对现有武器装备的技术改造等。严格地说,并不能把高技术截然地分为军用和民用,90%以上的科学技术成就均是军民兼用的,但是许多高技术都是首先应用在军事上,而且在高技术发展中,军用高技术往往起看带头作用。这是因为军事始终是社会生活中对科学技术的最新成就利用得最快最多的一个领域。另一方面,军事上的新需求又促进了高技术的发展。 高技术的基本特征是,“战略性、风险性、增值性、渗透性、带动性”。战略性,即指高技术状况是反映国家经济实力和国防实力的,直接关系到国家经济和军事地位;风险性,即高技术几乎都处在科学技术的前沿,它的发展具有明显的超前研究的特点;增值性,即它的应用可以大大提高经济效益和武器系统的效能,起着“力量倍增器”的作用;惨透性,即高技术本身往往都是一些综合性、交叉性很强的技术领域,表现于多学科之中;带动性,即高技术集约了各技术领域的精华.它广泛地应用到传统产业中去,就能带动各行业的技术进步。 从总体上讲,当代高技术包括相互支撑、相互联系的六大高技术群,即信息技术群、新材料技术群、新能源技术群、生物技术群、海洋技术群和航天技术群。主要包括九大技术产业:生物工程、生物医药、光电子信息、智能机械、软件、超导体、太阳能、空间、海洋产业等。每个高技术群又包括许许多多的高技术,而且相互交叉、渗透,还不断涌现着新的高技术学科。军用高技术主要来自信息、电磁、新材料、航天、航海、侦察、预警、制导、控制、隐形、夜视、核化、定向能技术等,而未来生物技术的发展,也将在军用高技术发展中,占有重要的一席之地。

什么是高成长,高创新,高科技企业

摘 要:和传统企业相比高新技术企业在很多方面有所不同,可以将高新技术企业的特征概括为高投入性、高技术人才密集性、高创新性、高增长性、高收益性、高风险性、组织结构扁平化以及合作和共享的组织文化等典型特征。 中国论文网 http://www.xzbu.com/1/view-4637999.htm  关键词:高新技术企业;高技术人才密集;高收益性;高风险性   高新技术(又称高科技,high-technology)一词产生于20世纪70年代,流行于20世纪80年代。由于高新技术本身是一个动态发展概念,目前国内外还没有公认的定义。在这一概念诞生初期,美国《韦氏第三版新国际词典增补9000词》中对高新技术的定义为:“使用包含尖端方法或尖端仪器的技术。”世界经济合作与发展组织(OECD)在1988年对高新技术所下的定义为:“高新技术是指那些需要以充满活力和持续进步的研究和开发为基础的迅速发展和高度综合的经济部门”。日本学者认为,高新技术是以当代尖端技术和下一代科学技术为基础建立起来的技术群。我国国家科技成果办公室对高新技术的定义是:“高新技术是建立在综合科学研究的基础上,处于当代科技前沿的,对发展生产力、促进社会文明和增强国家实力起先导作用的新技术群。”这一定义与其他的定义相比,更全面地反映了高新技术的本质特征,也符合我国国情,是本文所认同的一种定义。世界经济合作与发展组织(OECD)于1997年确定了九个高新技术行业,分别是“航空航天、计算机、电子通信、医药、科学仪器、电气机械、化学、非电气机械、军事装备”。?譹?讹而目前我国确定今后要重点发展的高新技术领域有生物技术、信息技术、新材料、新能源、空间技术和海洋技术。   高新技术企业的概念:高新技术企业是指在企业生产经营过程中,研究与开发费用投入大,拥有较高比率的科技型人才,并以研究开发、生产销售创新产品或创新技术服务的企业。   从上述定义可以看出,高新技术企业一般具有三个基本要素:第一,研究与开发在企业生产经营中十分重要,研发费用占企业销售收入的比例较高。第二,科技型人才占企业员工总数的比例较高,企业的生存和发展高度依赖于科技人才。第三,企业的产品或服务往往具有较高的科技含量,大多属于创新型产品或创新型技术服务。   和传统企业相比高新技术企业在很多方面有所不同(如表1.1),根据对比结果可以将高新技术企业的特征概括为高投入性、高技术人才密集性、高创新性、高增长性、高收益性、高风险性、组织结构扁平化以及合作和共享的组织文化等,以下从八个方面论述高新技术企业的八大特征。   一、高投入性   高新技术企业的高投入性主要表现在研发、研发产品商品化阶段的试验和推广、专用设备等方面需要大量的资金。从事高新技术研发要取得科技成果,需要投入大量的研究费用,而且技术难度越大、越复杂,需要投入的资金就越多。在开发阶段要经过中间试验,这一环节投入的费用弹性很大,有时投入很多而一无所获,有时需要多次试验、不断追加投入才能成功,中间试验费用在整个企业开发过程中所占的比例很大。在商品产业化阶段为了及时推向市场并且提高市场占有率需要投入巨大的广告费用和其它促销费用。因此,高新技术企业需要较高的资金投入,没有大量的资金投入,要想使高新技术企业不断发展是不可能的,甚至连企业的生存都有问题。据统计,高新技术企业的研发投入强度一般为5%-15%,最高的可达50%,将其研发成果商品化时,所需投资又要比研发投入强度高5-10倍。因此日本人把高新技术企业称为“食金虫工业”。?譺?讹   二、高技术人才密集性   高新技术企业是知识密集、技术密集型企业,从事的是智力活动,主要依赖人才及其智力和知识,和传统产业的最大区别,在于它是建立在知识的基础上,集技术、智力、信息、知识等高级生产要素为一体。从高新技术企业人员构成上看,从事技术研究和产品开发、设计的科技人员在企业员工总数中有较高比例,专业技术人员在企业中的作用远大于其他企业人员,据统计高新技术企业中具有工程和科学学位的人员,占员工总数的40-60%,相当于传统产业部门的5倍。?譻?讹高新技术企业的关键经营资源是人力资源,特别是高智力人力资源,即具有从事较高程度异质性劳动的人力资源。因此,高新技术企业发展过程中起着核心和关键作用的是高技术人才。   从高新技术企业人员构成上看,从事技术研究和产品开发、设计的科技人员在企业员工总数中有很高比例,科技人员在企业中的作用远大于企业其他人员,据统计高新技术企业中具有工程和科学学位的人员,占员工总数的40-60%,相当于传统产业部门的5倍。高新技术企业中的人力资本所有者包括创新者(主要指经营创新者和科研创新者)、管理者、生产者,由于创新活动是高新技术企业经营活动中的日常活动,因此,高新技术企业最重要的不是管理者,而是经营和技术的创新者。因此,在高新技术企业的价值创造中,科技型人力资本在价值创造中的重要作用逐步显现。   三、高创新性   创新性是高新技术企业一项基本特点,在高新技术企业认定时一个重要指标就是新产品和新技术在销售额中的比重。其实,技术创新、产品创新、市场创新以及管理创新在高新技术企业中的作用都十分显著。高新技术企业要保持竞争优势,必须时时刻刻围绕创新这条主线开展工作,不创新甚至创新缓慢,企业将会面临被淘汰,寻求不断的创新是高新技术企业不断获取利润的源泉。技术创新是动力,除了对技术特有的保护外,非常重视创新的投入;制度创新是保障,不断寻求新的激励机制和组织结构;高新技术产品生命周期短、更新快、时效性强且难以预料,所以要求不断地进行产品创新,以适应新的市场需求。   处于知识经济时代的知识型企业(高新技术企业是知识型企业的一种,所以这里的论述同样适用于高新技术企业),社会知识存量的急剧变动使得知识和创新成为企业生存的必要条件,创新活动逐渐成为知识型企业的日常活动。为了追求专业化分工的利益和节省交易费用,专门从事创新活动的个体从普通劳动者中分离出来。在知识型企业中,经营职能和管理职能已经发生了分离,创新者成为知识型企业中真正意义上的经营者,他承担着企业的经营风险,决定着企业的生产方向;而传统意义上的经营者已经蜕变为单纯的管理者,他仅仅负责组织企业的生产和监督生产工人。可见,在知识型企业中管理者的作用大大下降。由于知识经济时代社会知识存量的急剧变动,在知识型企业中,最重要的不只是企业家,而是更广泛的知识的创新能力。企业的首要问题是要设计一种机制,在这种机制下有创新能力的人能够被选为创新者。   四、高成长性   高新技术企业的创新产品一旦在市场上获得成功,由于专利保护、技术诀窍、技术领先、特许经营等因素,将给企业带来巨大的竞争优势,创新产品凭借其新颖性和新技术特性将迅速地占领市场,其投资回报率可能在短短几年时间内增长几十倍甚至上百倍,获得巨大的经济效益,高收益的特点也促成了高增长,从而在短期内可能成长为大公司,高新技术企业的发展具有跳跃性。   五、高风险性   高新技术企业的高风险性主要来自于技术的不确定性和市场的不确定性。高新技术产品的研发过程本身具有的不确定性,决定了研发活动具有很高的失败率。新技术转化为现实的商品或服务也具有明显的不确定性,存在着技术失败而造成损失的风险。新技术的形成还有一个生成、发展、应用、淘汰的周期规律,它总是处于动态变化中,其更新换代的周期在不断缩短,前一时期确认为新的技术,随着技术的进步与发展,很快会被新的更高的技术所代替而遭淘汰。市场的不确定性主要体现在市场接受能力难以把握,新市场的开发受许多因素制约,具有不确定性;高新技术产品生命周期短、更新快、时效性强难以预料,这使得高新技术企业市场风险更大。高新技术企业的风险性与高新技术的复杂创新性呈同步增长趋势,技术的复杂程度越高,技术的含量越大,技术的创新难度越大,企业所承担的风险也大。此外,高新技术企业还面临人才风险。高新技术企业对科技人才的高度依赖带来了人才风险。高新技术企业在技术创新中对科技人才的依赖性极强,而科技人才又有着市场竞争激烈、流动性强的外部环境,如若关键技术人才流失,会使高新技术企业遭受沉重的打击。据统计,美国高新技术公司10年的成活率在5-10%之间。?譼?讹我国北京市高新技术企业在2000年、2001年、2002年的注销率分别为11.27%、15.46%、9.12%,2000年和2001年的注销率是全部企业注销率的1.2倍和2.4倍。?誉?讹   六、高收益性   高新技术企业的高收益性来源于其技术和产品的高创新性,这种创新在一定时期内具有垄断性特征,由于市场的旺盛需求和技术的垄断,能吸引愿意支付高价格的购买者,会带来高额的利润回报。高新技术企业在创业成功之后,通常可以得到数十倍于初始投入的巨大收益。在风险投资基金投资的高新技术项目中,虽然70%是失败的,但30%成功的项目所带来的利润足以弥补他们的全部损失,并使其保持较高的盈利水平。从股票市场上高新技术板快的表现,也足以说明高新技术企业的高收益性。?譾?讹   七、组织结构扁平化   高新技术企业以技术创新和灵活性作为战略目标,为了实现这一目标企业的组织结构必须相适应。进行技术创新,并为企业的技术和知识积累、流动和共享创造条件,组织结构就必须是扁平化的和有弹性的。高新技术企业的核心业务是研究开发、营销管理、技术与产品的集成,科技人员以项目为单位,这种结构是根据企业已签或待签的几个大中型项目的要求,把工程技术和研发部门分为几个相应的项目组,设立项目经理,并实行项目经理负责制。高新技术企业组织还具有柔性化、边界模糊特点,在高新技术企业经常采用跨部门工作小组或项目组完成某一项任务,如为了使产品研发与销售工作有机结合,研发人员也参与产品的推广和销售,而销售人员也参与研发工作中。所以,高新技术企业的组织形态,应该是扁平化、网络化、高弹性的,企业由一个个团队组成,以更好地适应快速变化的需求和竞争。   八、合作和共享的组织文化   高新技术企业组织文化的特点是鼓励创新、合作、共享和宽容失败。高新技术企业只有不断的创新才能满足知识经济需要,团队工作方式需要员工相互合作、知识共享,同时建立学习型组织鼓励员工不断学习。高新技术企业的成果具有高度的不确定性和不可预测性,因此必须对失败有较高的容忍度,以促进企业科技人员的创新行为和创业精神。知识的共享可以产生创新的灵感和新知识。一个思想交换另一个思想,彼此会有两个思想。知识具有流动性和价值可多次转移的特性,其共享的过程并不是一个人到另一个人的转移,而是彼此共同的拥有。企业要开展能够让大多数员工受益的、能够满足整个组织需要的知识管理,会让组织有一种向上的趋势。   引文注释   ①Thomas H.

A dream is an inexhaustible source of energy that keeps our enthusiasm burning, and kindles our desire to enhance our spiritual cultivation, refine our character, and upgrade our quality of life. A life without a dream is like a bird with broken wings, confined to a cage and oblivious of what lies beyond the range of its vision. On the contrary, a man with a dream is like a warrior armed with ambition, foresight and gallantry, daring to step into an unknown domain to make a journey of adventure. It is dream that adds fullness, variety, and spice to our life and makes it worth living. I have a dream. It is d dream that is deeply rooted in human nature. I dream that one day people of all origins can live in harmony and peace without being discriminated against or persecuted. The bounty of the earth can be shared by every single human being. Mutual respect will guarantee the existence and continuation of the diversity of customs and cultures. Love, sympathy, and cooperation will alleviate the sufferings and disasters inflicted upon our fellow men. Respect for basic human rights will put an end to social injustices and evils. When my dream comes true, all men will be truly equal, happy, and free. 2020高二期末英语作文3 In order to make our city cleaner and more beautiful, the young volunteers of our school went to the People"s Park this morning and offered our help.

People like to recall their passed youth, which makes such movies sell good. But I find the common things about these movies, all the protagonists" youth are about fighting, love and other negative things. I understand the directors" intention, they want to tell people youth is not perfect and having pities. Of course movie is exaggerating, the real youth is about studying, at least, most people have worked so hard to get into their ideal colleges. What the movies describe make up some people"s youth, for which they don"t have the chance to experience. We should not be misled by these movies, for the teenagers, their job is to study, so that they can have a bright future. 【翻译】很多年以前,关于青春的电影很受欢迎,此后每年,我们都可以看到很多热门电影是关于主人公逝去的青春。人们喜欢回忆他们逝去的青春,这才是让这类电影好卖的原因。但是我发现了这些电影的共同点,那就是所有的主人公的青春都是关于大家,恋爱和其他消极的东西。我明白导演们的意图,他们想要告诉人们青春是不完美的,存在遗憾。当然电影是夸张化的,真正的青春是关于学习,至少,大部分人是如此努力的学习,为了进入理想的大学。电影所刻画的弥补了一些人的青春,对于他们没有机会去体验这些东西。我们不应该被电影误导,对于青少年来说,他们的工作是学习,这样他们才能有一个美好的未来。 关于现实的英语作文 When college students graduate, most of them will choose to join the civil servants exam or further study, these two choices become more and more popular, they have the common side, that is stability. The young people pay special attention to stability when they find a job, because in today"s society, the pressure is so heavy, they fear to lose job, working for the government is the best choice for them, they don"t have to worry about losing jobs. While they are so young, they should be energetic, they should do the pioneering work, they have nothing to lose, because they have nothing at the beginning. If the young people don"t dare to fight, they waste their youth, all their lives are insipid, when they are old, they look back on their youth, just nothing leaves. If the young people want to do pioneering work, just do it, take no hesitation. 当大学生毕业,很多人会选择参加公务员考试或者深造,这两个选择有一个共同点,那就是稳定。年轻人在找工作的时候很注重稳定,因为在今天的社会,压力是很大的,他们害怕失去工作,为政府工作对于他们来说是最好的选择,不用担心丢掉工作。然而他们是那么的年轻,应该充满活力,应该去创业,他们没有什么输不起,因为他们刚开始本来就一无所有。如果年轻人都害怕奋斗,浪费了青春,他们的一生都平淡无奇,当他们老了,回望青春,发现什么也没留下。如果年轻人想要创业,那就去吧,不要犹豫。 我推荐: 高中英语作文带翻译100字 新颖的高考英语作文范文 As the development of high technology, nowadays, people have access to all kinds of new products, these high technology products bring convenience to people"s life.

科技英语范文大全

  实际上科学和技术既有密切联络,又有重要区别。下面是我给大家整理的科技英语范文,供大家参阅!   科技英语范文:关于科技的发展   With the rapid development of technology, the popularity of the network is more and more widely, more and more people like to make ments on the various events in the network. A relatively rare event or quite shocking events also can be easy to bee the center of network public opinion. And the reason of network public opinion happening is that the rapid development of the network makes the rapid dissemination of rmation. Every *** all events are likely to bee the center of network public opinion. And the second reason is many people have a strong sense of Equal and justice. And the network is a very good platform to make their speech attention and recognition. So that many people like to go to internet to make ments on it. In the course of time the network public opinion has bee more and more frequent But the emergence of the network public opinion brings different influence.First of all is the good side.Network public opinion can supervise the false, unfair events,officials, play a supervisory role.But on the other hand, The network of public opinion also caused a lot of bad influence.Such as Human flesh search also easy to cause the invasion of privacy.   科技英语范文:Is Science Dangerous   The rapid development of science and technology has brought about great changes to human life, including great harms and disasters .Then people enter into endless argument about whether science is dangerous or not.   So many examples can be figured out to prove the danger of science. Advanced technology can be easily manipulated by irresponsible persons as well as terrorist. Such as the Disaster 911, airplanes fly into buildings, fire burning, huge structures collapse, a lot of victims such as intellectual and business elites were sacrificed. Besides, As technology bees more powerful day by day , we"ll be placent and lazy. Increased dependency on modern tools like calculators has reduced on our creativity. Students can"t solve a very simple mathematical equation without using a calculator. This affects the way these students uses their brains and reduces on the level of creativity.   Just like the saying goes that every coin has two sides. However, it ‘s obvious that we make the decision to choose which side. After 911, people condemn the terrorist not airplays. Student who got low marks should rethink his carelessness and laziness but not pass the buck to the calculator.   Any way, There is no dangerous science, but dangerous and irresponsible people. We are working very hard to solve such problems that e along with advances in science and technology, but the efforts are not sufficient and not very successful. Actually, the key lies in the user. Moralities such as responsibility, diligence and goodness should never be lost in our heart. Otherwise , the world would be full of danger even we turn back to the stone age.   科技英语范文:The impact of technology on personal munication   Nowadays, with the rapid development of science and technology, people"s life takes on a brand new look, especially the munication.   No one can deny that we enjoy the convenience of hi-tech products such as mobile phones and puters. They have enormously changed the ways of munication in shortening the distance between people as well as making instant contact possible. The speeding-up mobile technology has efficiently promoted the dream of “global village”.   However, each coin has two sides. Since mobile technology has progressed rapidly, there occurs some lamentable phenomenon. The high technology make our municationmoreconvenient, but it doesn"t mean   科技英语范文:高科技   The development of science and technology makes our life more fortable and convenient. However, scientists have created many problems, which are not easy to be resolved, such as air pollution, the deterioration of environment and the scarcity of natural resources, to which we must some solutions.   Modern science and technology render people many advantages. Modern telemunication shortens the distance between people and makes munication much easier. Internet is widely used now not only for collection of abundant rmation but also for correspondence. Email, the most effective munication device now, is being very popular. Besides, telephone and mobile phone make contact more convenient than before.   Modern transportation, such as airplanes and high-speed trains make our journey *** ooth and fast. With the help of modern transportation, people can go everywhere they prefer to. The journey to outer space and other planets is not a dream any more. Rockets and space shuttles can help us realize the dream of space travel.   Modern medicine prolongs peoples life and relieves patients of sufferings from many diseases. Cancer and AIDS are fatal to peoples health. Thanks to the endeavors scientists have made, these diseases bee treatable.   However, the process of scientific development also arouses many sever problems to our human beings. Internet, though widely used in modern munication, is easy to be destroyed by puter virus. Outer space exploration has produced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-made satellite. Industrialization is making natural resources bee scarce.   Confronted with these problems, scientists are seeking prompt and feasible solutions. The development of science and technology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent.

By extra studies,they maintain,their children are able to obtain many kinds of practical skills and useful knowledge,which will put them in a beneficial position in the future job markets when they grow up.   许多家长相信额外的教育活动有许多优点,通过学习,他们的孩子可以获得很多实践技能和有用的知识,当他们长大后,这些对他们就业是大有好处的。   73. In the first place,extra studies bring about unhealthy impacts on physical growth of children. Educational experts point out that,it is equally important to take some sport activities instead of extra studies when children have spent the whole day in a boring classroom.   首先,额外的学习对孩子们的身体发育是不利的。教育专家指出,孩子们在枯燥的教室里呆了一整天后,从事一些体育活动,而不是额外的学习,是非常重要的。   74. Children are undergoing fast physical development;lack of physical exercise may produce disastrous influence on their later life.   孩子们正处于身体快速发育时期,缺乏体育锻炼可能会对他们未来的生活造成严重的影响。   75. In the second place,from psychological aspect,the majority of children seem to tend to have an unfavorable attitude toward additional educational activities.   第二,从心理上讲,大部分孩子似乎对额外的学习没有什么好感。   76. It is hard to imagine a student focusing their energy on textbook while other children are playing.   当别的孩子在玩耍的时候,很难想象一个学生能集中精力在课本上。   77. Moreover,children will have less time to play and communicate with their peers due to extra studies,consequently,it is difficult to develop and cultivate their character and interpersonal skills. They may become more solitary and even suffer from certain mental illness.   而且,由于要额外地学习,孩子们没有多少时间和同龄的孩子玩耍和交流,很难培养他们的个性和交际能力。他们可能变得孤僻甚至产生某些心理疾病。   78. From what has been discussed above,we may safely draw the conclusion that,although extra studies indeed enjoy many obvious advantages,its disadvantages shouldn"t be ignored and far outweigh its advantages. It is absurd to force children to take extra studies after school.   通过以上讨论,我们可以得出结论:尽管额外学习的确有很多优点,但它的缺点不可忽视,且远大于它的优点。因此,放学后强迫孩子额外学习是不明智的。   79. Any parents should place considerable emphasis on their children to keep the balance between play and study. As an old saying goes:All work and no play makes Jack a dull boy.   任何家长都应非常重视保持孩子在学习与玩耍的平衡,正如那句老话:只工作,不玩耍,聪明的孩子会变傻。   80. There is a growing tendency for parent these days to stay at home to look after their children instead of returning to work earlier.   现在,父亲或母亲留在家里照顾他们的孩子而不愿过早返回工作岗位正成为增加的趋势。   81. Parents are firmly convinced that,to send their child to kindergartens or nursery schools will have an unfavorable influence on the growth of children.   父母们坚定地相信把孩子送到幼儿园对他们的成长不利。   82. However,this idea is now being questioned by more and more experts,who point out that it is unhealthy for children who always stay with their parents at home.   然而,这一想法正遭受越来越多的专家的质疑,他们指出,孩子总是呆在家里,和父母在一起,是不健康的。   83. Although parent would be able to devote much more time and energy to their children,it must be admitted that,parent has less experience and knowledge about how to educate and supervise children,when compared with professional teachers working in kindergartens or nursery schools.   尽管父母能在他们孩子身上投入更多时间和精力,但是必须承认,与工作在幼儿园的专职教师相比,他们在如何管理教育孩子方面缺乏知识和经验。   84. From what has been discussed above,we may safely draw a conclusion that,although the parents" desire to look after children by themselves is understandable,its disadvantages far outweigh the advantages.   通过以上讨论,我们可以得出如下结论:尽管家长想亲自照看孩子的愿望是可以理解的,但是这样做的缺点远大于优点。   85. Parents should be encouraged to send their children to nursery schools,which will bring about profound impacts on children and families,and even the society as a whole.   应该鼓励父母将他们的孩子送到幼儿园,这将对孩子,家庭,甚至整个社会产生深远的影响。   86. Many leaders of government always go into raptures mere mention of artistic and cultural projects. They are forever talking about the nice parks,the smart sculptures in central city and the art galleries with various valuable rarities. Nothing,they maintain,is more essential than such projects in the economic growth.   只要一提起艺术和文化项目,一些政府领导就会兴奋不已,他们滔滔不绝地说着美丽的公园,城市中心漂亮的雕塑,还有满是稀世珍宝的艺术展览馆。他们认为在经济发展中,没有什么比这些艺术项目更重要了。   87. But is it really the case?The information I"ve collected over last few years leads me to believe that artistic and cultural projects may be less useful than many governments think. In fact,basic infrastructure projects are playing extremely important role and should be given priority.   这是真的吗?这些年我收集的信息让我相信这些文化、艺术项目并没有许多政府想象的那么重要。事实上,基础设施建设非常重要,应该放在首位。   88. Those who are in favor of artistic and cultural projects advocate that cultural environment will attract more tourists,which will bring huge profits to local residents. Some people even equate the build of such projects with the improving of economic construction.   那些赞成建设文化艺术项目的人认为文化环境会吸引更多的游客,这将给当地居民带来巨大的利益。一些人甚至把建设文化艺术项目与发展经济建设等同起来。   89. Unfortunately,there is very few evidence that big companies are willing to invest a huge sums of money in a place without sufficient basic projects,such as supplies of electricity and water.   然而,很少有证据表明大公司愿意把巨额的资金投到一个连水电这些基础设施都不完善的地方去。   90. From what has been discussed above,it would be reasonable to believe that basic projects play far more important role than artistic and cultural projects in people"s life and economic growth.   通过以上讨论,我们有理由相信在人们的生活和经济发展方面,基础建设比艺术文化项目发挥更大的作用。   91. Those urban planners who are blind to this point will pay a heavy price,which they cannot afford it.   那些城市的规划者们如果忽视这一点,将会付出他们无法承受的代价。   92. There is a growing tendency these days for many people who live in rural areas to come into and work in city. This problem has caused wide public concern in most cities all over the world.   农民进城打工正成为增长的趋势,这一问题在世界上大部分城市已引起普遍关注。   93. An investigation shows that many emigrants think that working at city provide them with not only a higher salary but also the opportunity of learning new skills.   一项调查显示许多民工认为在城市打工不仅有较高的收入,而且能学到一些新技术。   94. It must be noted that improvement in agriculture seems to not be able to catch up with the increase in population of rural areas and there are millions of peasants who still live a miserable life and have to face the dangers of exposure and starvation.   必须指出,农业的发展似乎赶不上农村人口的增加,并且仍有成千上万的农民过着缺衣挨饿的贫寒生活。   95. Although rural emigrants contribute greatly to the economic growth of the cities,they may inevitably bring about many negative impacts.   尽管民工对城市的经济发展做出了巨大贡献,然而他们也不可避免的带来了一些负面影响。   96. Many sociologists point out that rural emigrants are putting pressure on population control and social order; that they are threatening to take already scarce city jobs;and that they have worsened traffic and public health problems.   许多社会学家指出民工正给人口控制和社会治安带来压力。他们正在威胁着本已萧条的工作市场,他们恶化了交通和公共卫生状况。   97. It is suggested that governments ought to make efforts to reduce the increasing gap between cities and countryside. They ought to set aside an appropriate fund for improvement of the standard of peasants" lives. They ought to invite some experts in agriculture to share their experiences,information and knowledge with peasants,which will contribute directly to the economic growth of rural areas.   建议政府应该努力减少正在拉大的城乡差距。应该划拨适当的资金提高农民的生活水平;应该邀请农业专家向农民介绍他们的经验,知识和信息,这些将有助于发展农村经济。   98. In conclusion,we must take into account this problem rationally and place more emphases on peasants" lives. Any government that is blind to this point will pay a heavy price.   总之,我们应理智考虑这一问题,重视农民的生活。任何政府忽视这一点都将付出巨大的代价。   99. Although many experts from universities and institutes consistently maintain that it is an inevitable part of an independent life,parents in growing numbers are starting to realize that people,including teachers and experts in education,should pay considerable attention to this problem.   尽管来自高校和研究院的许多专家坚持认为这是独立生活不可避免的一部分,然而越来越多的家长开始意识到包括教师和教育专家在内的人们应该认真对待这一问题。   100. As for me,it is essential to know,at first,what kind of problems young students possible would encounter on campus.   我认为,首先应看看学生们在校园可能遇到哪些问题。

explain the difference between low-tech and high-tech farming. 用英文答题 谢谢了。

high-tech farmingHigh-tech farming mainly refers to agricultural methods using the latest technology, like hydrophonics and aerophonics. That is to say growing veggies in water or in the air only, without the use of soil. And there"s also orchid farms and ornamental fish. It"s also called agrotechnoloy here. There are minimal physical inputs to the system, but it is capital intensive since large capital outlay is required to buy specialized equipment, maintenance, training of labour etc. It"s also a commercial farming system, farmers invest in them both for local and export markets; technical know-how is a must, for example, for hydrophonics computers are used to monitor; it is labour-intensive because of the training of lab technicians, scientists, chemists and farm-hands; it uses farming technologiy to increase yields; it has high output and market value because the so-called hygenic (usually pesticide-free) conditions appeal to all health-conscious people out there who don"t mind paying more; it is dependent on research and development. Like growing temperate vegetables in a tropical climate, or genetic engineering developing disease-resistant plants with nice colours, or transgenic animals.High Tech vs. Low Tech FarmingKlinkenborg argues that high tech genetic modification is on track to replace low tech farming methods. While many remain nostalgic for the pastoral farming culture of yore, few realize that having large monoculture crops planted across an increasing amount of our agricultural land has serious implications for our food supply. For example, different species of rice don"t just taste different. Each species reacts differently to climatological variation. As conditions change, a genetically modified mega-chain of rice or corn could suffer under a particular change more dramatically than another. Thus, the failure of just one species to effectively adapt could cause a widespread blight, which, in turn, could lead to famine. Adaptability in cultivating and harvesting a particular type of seed can be just as important as having access to a diversity of seeds in the first place. I recently observed that the underlying issue is that keeping heirloom seeds in seed banks could become an ineffective means for preserving plant species when farmers no longer know how to cultivate different variations of a crop.

200分求关于High Impact Polystyrene耐冲击性聚苯乙烯的所有资料,包括国内外市

HIPS 正名:High Impact Polystyrene耐冲击性聚苯乙烯 性能:耐冲击性聚苯乙烯(HIPS) 耐冲击性聚苯乙烯是通过在聚苯乙烯中添加聚丁基橡胶颗粒的办法生产的一种抗冲击的聚苯乙烯产品。这种聚苯乙烯产品会添加微米级橡胶颗粒并通过枝接的办法把聚苯乙烯和橡胶颗粒连接在一起。 当受到冲击时,裂纹扩展的尖端应力会被相对柔软的橡胶颗粒释放掉。因此裂纹的扩展受到阻碍,抗冲击性得到了提高。 聚苯乙烯是一种用途广泛的脆性塑料。你现在正在使用的计算机的外壳就是聚苯乙烯的。透明的塑料水杯,包装用的泡沫塑料也是由聚苯乙烯制成的。 聚苯乙烯属于聚烯烃,是由苯乙烯通过自由基聚合而成的。 通过茂金属催化聚合可以得到一种新型聚苯乙烯,即间同聚苯乙烯(syndiotactic)。间同聚苯乙烯上的苯环交替地连接的主链的两侧,而普通聚苯乙烯的苯环在无规地连接在主链两侧。 间同聚苯乙烯(syndiotactic)是结晶高分子,熔点达到270℃。 在苯乙烯聚合体系中中加入聚丁二烯,使苯乙烯在聚丁二烯主链上接枝聚合。聚苯乙烯和聚丁二烯是不相容的,因此苯乙烯和丁二烯链段分别聚集,产生相分离。 这些聚丁二烯相区可以吸收冲击能,从而提高了聚苯乙烯的冲击强度 具体的市场行情建议到化通社去看一下,网址为: http://news.chemnet.com/tag/t--%C4%CD%B3%E5%BB%F7%D0%D4%BE%DB%B1%BD%D2%D2%CF%A9----2.html High Impact Polystyrene – HIPS Polymer Type Thermoplastic Advantages Tougher than polystyrene.

以High Technologies and our life 为题,写一篇英语短文

Growing up in the 90"s was like living in a happy-go-lucky era. Everyone seems to be carefree. Everything seems to be temporary. The world seems to be moving so slow.

No one to care for and no obligation means freedom to the fullest.Things are becoming more different as time passes; you begin to change both emotionally and mentally. Life is starting to devour you seriously. You start to begin to become responsible and caring for somebody has become full of life. You become conscious that living life to the fullest is a must as you begin to get older because you now realize that each day passes quickly. Changing your outlook to life as well as lifestyle is being affected by being attached to somebody.I met my future wife when I stated to work after college in a local company in my hometown.Love at first sight and I know that my life will change with this woman. It sure did, after a year of being together; we got married and we were blessed with two children. My life became so different in contrast to what my life was during those carefree days. My life was bliss until I was given a chance to work abroad.If you are not used of being away from your loved ones, it can be pretty miserable and very lonesome. That"s what happened to me.

想要一篇简短的英文介绍美国,三十句左右就可以

Mainly located on the continent of North America, the United States is a federal republic country composed of 50 states, one capital districts and several oversea territories. With the area of around 9.6 million squared kilometers and over 300 million citizens, the United States is the fourth largest country in the world by landmass, and the thrid largest country by population. The capital city of the United States is Washington D.C., which located on a river bank between states of Maryland and Virginia. The biggest city of the United States is New York City, which is also one of three global cities in the world. Other major cities in this country include Los Angeles, Boston, Houston, Chicago, San Diego, Miami, Denver, Philadelphia and Seattle. The United States is a diverse country in terms of culture and geography. Although there are Native American tribes scattered across the land, most of this country"s citizens are descendants of people from all over the world. It is a result of this nation"s history. Before the United States was established, North America was colonized by European empires, such as England, France, Spain and Netherlands. Slaves were also shiped from Africa to North America. After the independent war, descendants of Europeans and African people became the first generation of the newly-established United States. Attracted by its freedom and the American Dreams, people from many other countries, such as Mexico, Brazil, China, Japan, Ireland, Poland and Germany, immigrated to the United States in 19th and 20th centuries. One of the major events that attracted a large wave of immigration was the 1849 Gold Rush in California. The United States welcomes all sorts of different cultures, and people living in this country can preserve their own cultures as much as they want. As a result, you can see cultures from different parts of the world within the boundary of the United States today.In terms of geography, this country is also diverse. There are different geographical provinces in this country. New England, Mid Atlantic and Southwest are three provinces along the coast line of Atlantic Ocean. There are many financial or trading centers located in this area. To the west of them, there is a mountain range called Appalachia. This mountain is known for its rich natural gas and coal deposations, as well as peaceful villages in the woods. To the farther west, it comes the Great Lakes, Midwest and the Grand Plain. The area around Great Lakes is the old industrial and manufacturing center of the United States. There are many famous industrial cities, such as Pittsburgh, Youngstown, Detroit, Cincinnati and Cleveland. After 1970s, industries, especially the steel and coal industry, declined a lot in this area. Many furnaces and factories were closed down and abandoned. As a result, this area got a nickname of "Rust Belt". The Grand Plain was the home of agriculture in this country. Massive farms and fields distributed widely across the flat land.
