为什么工作完成之后的lately不能省略?

The job"s done. =The job is(was) done. 这项工作(这个活儿)完成了。

这句话属于被动语态的一般现在时或过去时。而lately是副词最近、近来,这个词是现在完成时的标配,即用到它一定会跟着现在完成时。因此,lately是不可以出现在上面的句子里。

lately和recently的区别

1. 什么是lately和recentlyLately和recently都表示最近的意思,常用于英语口语和书面语中,但它们有一些区别。Lately通常指最近过去的时间,通常是几个星期到几个月之间的时间段。而Recently则指更广泛的时间段,可以是最近的一段时间,在数天到数周之内,也可以是数个月或数年的时间段。2. Lately和recently的用法Lately和recently可以在句子中用作副词,修饰动词或形容词,以表示一个行动或状态的“新鲜度”。例如:She has been lately very busy with her work. (她最近一直忙于工作。)Recently, the weather has become colder. (最近天气变冷了。)3. 这两个词的不同例句尽管这两个单词的含义相似,但是在某些情况下却不能互相替代。例如:- LatelyLately通常用来描述与过去几周和几个月相关的事情,例如:I haven"t seen my friend lately. (我最近没有见到我的朋友。)Lately, sales have been increasing. (最近,销售额有所增加。)- RecentlyRecently则适用于更广泛的时间段,可以涵盖过去几天到过去几年,例如:Recently, I"ve been thinking a lot about my future. (最近,我一直在思考我的未来。)I haven"t been to the beach recently. (我最近没有去海滩。)4. 表达方式上的区别除了在使用时指代不同的时间段之外,lately和recently还有一些在表达方式上的差异。例如:Lately这个单词可能会让人联想到一个相对较短的时间段,因此通常具有褒义。使用这个词可以表达一个积极的状态或变化,例如:Lately, I"ve been feeling great. (最近我感觉很好。)Sales have been up lately. (近期销售额呈上升趋势。)相比之下,recently则更加务实。这个单词强调的是一个事件发生的事实,不带任何情感色彩,例如:Recently, the company has hired several new employees. (最近,公司雇佣了几名新员工。)I"ve been working hard at the gym recently. (我最近一直在健身房努力锻炼。)5. 使用lately和recently的注意点虽然Lately和recently的区别较小,但是在使用时还是要注意一些细节。以下是一些需要注意的事项:- 通常情况下,Lately所指的时间比Recently的时间短,应特别注意这一点。- 无论是Lately还是Recently在句子中均为副词,它们不能用于名词或代词。- 如果你要在英语口语中使用Lately和Recently,要注意两者的发音是不同的,Lately发[le?tli],而Recently发[r?sntli]。6. 案例分析以下是一些使用Lately和Recently的例子:- Lately我感觉身体很健康,每天都能睡好觉。- Recently我很忙,几乎每天都要加班。- Lately,我已经开始更加关注我的健康状况。- Recently,我决定开始学习一门新技能。7. 总结虽然Lately和Recently在实际用法中存在区别,但这两个单词的大致含义非常相似,都表示“最近的”意思。选择哪个单词要视情况而定,但是无论哪个单词,都需要根据上下文和具体时间段来使用。同时,还需要注意这两个单词所表达的情感色彩和发音的区别。

lately可以放在句首吗?

The job"s done. =The job is(was) done. 这项工作(这个活儿)完成了。这句话属于被动语态的一般现在时或过去时。而lately是副词最近、近来,这个词是现在完成时的标配,即用到它一定会跟着现在完成时。因此,lately是不可以出现在上面的句子里。

工业乙烯是如何生产的 会对周边环境造成污染吗?

聚乙烯生产方法:聚乙烯按聚合压力可以分为高压法、中压法、低压法;按介质来分可以分为淤浆法、溶液法、气相法。   主要生产工艺:目前世界上拥有聚乙烯技术的公司很多,拥有LDPE技术的有7家,LLDPE和全密度技术的企业有10家,HDPE技术的企业有12家。从技术发展情况来看,高压法生产的LDPE是PE树脂生产中技术最成熟的方法,釜式法和管式法工艺技术均已成熟,目前这两种生产工艺技术同时并存。国外各公司普遍采用低温高活性催化剂引发聚合体系,可降低反应温度和压力。  高压法生产LDPE将向大型化、管式化方向发展。而低压法生产HDPE和LLDPE,主要采用钛系和络系催化剂,欧洲和日本大多采用钛系催化剂,而美国大多采用络系催化剂。  目前世界上主要应用的聚乙烯生产技术共用11种,我国的PE生产工艺有8种。  (1)高压管式和釜式反应工艺  (2)三井化学低压淤液法CX工艺   (3)BP气相法Innovene生产工艺   (4)雪佛龙-菲利蒲斯公司双环管反应器LPE工艺   (5)北欧化工北星(Bastar)双峰工艺   (6)低压气相法Unipol工艺  (7)巴赛尔聚烯烃公司Hostalen工艺   (8)Sclartech溶液法生产工艺  催化剂技术:催化剂是PE工工艺关键部分,也是其技术开发的焦点。特别是1991年茂金属催化剂在美国实现了工业化,使得PE生产技术进入了新的发展阶段。  目前世界各大PE生产企业大都已涉足茂金属PE(mPE)生产领域,如陶氏化学、伊士曼、旭化成、阿托菲纳、雪佛龙-菲利浦斯等公司。  日本旭化成化学购买陶氏化学的茂金属催化剂专利Insite,采用淤浆法生产工艺生产茂金属高密度聚乙烯(mHDPE),牌号为Creolex。由于性能优越,mPE1995年进入商业化发展以来,全球mPE树脂的消费量每年翻一番。预计到2010年,全球mPE产能将达到1700万吨,其中:mLLDPE为700万吨、mHDPE为600万吨。  目前PE催化剂已经发展到第三代,日本三井化学和陶氏化学合作开发出新一代茂金属(Post-metallocene)催化剂。与传统茂金属和Z-N型催化剂不同,该催化剂可使极性单体如甲基丙烯酸甲酯、醋酸乙烯酯等与烯烃共聚,从而可用于开发具有粘结性、耐油性及气体阻隔性能的全新聚烯烃树脂。  我国非常重视PE生产技术,PE生产技术创新一直被列入国家技术创新计划项目。针对国内PE生产以气相法工艺为主,产品牌号切换困难、过渡料多的问题,近年来国内PE生产企业纷纷开展了以现有聚乙烯生产技术改造为依托,气相法聚乙烯冷凝、超冷凝工艺和淤浆法聚乙烯外循环工艺的开发工作,并取得实效。  目前我国Uuipol工艺的大部分生产装置已经采用国产冷凝技术进行了改扩建,产量已经超出装置原设计能力120%~200%。  薄膜 低密度聚乙烯总产量的一半以上经吹塑制成薄膜,这种薄膜有良好的透明性和一定的抗拉强度,广泛用作各种食品、衣物、医药、化肥、工业品的包装材料以及农用薄膜(见彩图)。也可用挤出法加工成复合薄膜用于包装重物。1975年以来,高密度聚乙烯薄膜也得到发展,它的强度高、耐低温、防潮,并有良好的印刷性和可加工性。线型低密度聚乙烯的最大用途也是制成薄膜,其强度、韧性均优于低密度聚乙烯,耐刺穿性和刚性也较好,透明性虽较差,仍稍优于高密度聚乙烯。此外,还可以在纸、铝箔或其他塑料薄膜上挤出涂布聚乙烯涂层,制成高分子复合材料。   中空制品 高密度聚乙烯强度较高,适宜作中空制品。可用吹塑法制成瓶、桶、罐、槽等容器,或用浇铸法制成槽车罐和贮罐等大型容器。   管板材 挤出法可生产聚乙烯管材,高密度聚乙烯管强度较高,适于地下铺设。挤出的板材可进行二次加工。也可用发泡挤出和发泡注射法将高密度聚乙烯制成低泡沫塑料,作台板和建筑材料(见建筑用高分子材料)。   纤维 中国称为乙纶,一般采用低压聚乙烯作原料,纺制成合成纤维。乙纶主要用于生产渔网和绳索,或纺成短纤维后用作絮片,也可用于工业耐酸碱织物。目前已研制出超高强度聚乙烯纤维(强度可达3~4GPa),可用作防弹背心,汽车和海上作业用的复合材料。   杂品 用注射成型法生产的杂品包括日用杂品、人造花卉、周转箱(见彩图)、小型容器、自行车和拖拉机的零件等。制造结构件时要用高密度聚乙烯。   聚乙烯改性 聚乙烯的改性品种主要有氯化聚乙烯、氯磺化聚乙烯、交联聚乙烯和共混改性品种。   氯化聚乙烯 以氯部分取代聚乙烯中的氢原子而得到的无规氯化物。氯化是在光或过氧化物的引发下进行的,工业上主要采用水相悬浮法来生产。由于原料聚乙烯的分子量及其分布、支化度及氯化后的氯化度、氯原子分布和残存结晶度的不同,可得到从橡胶状到硬质塑料状的氯化聚乙烯。主要用途是作聚氯乙烯的改性剂,以改善聚氯乙烯抗冲击性能。氯化聚乙烯本身还可作为电绝缘材料和地面材料。   氯磺化聚乙烯 当聚乙烯与含有二氧化硫的氯作用时,分子中的部分氢原子被氯和少量的磺酰氯(-SO2Cl)基团取代, 就得到氯磺化聚乙烯。主要的工业制法为悬浮法。氯磺化聚乙烯耐臭氧、耐化学腐蚀、耐油、耐热、耐光、耐磨和抗拉强度较好,是一种综合性能良好的弹性体,可用以制作接触食品的设备部件。   交联聚乙烯 采用辐射法(X射线、电子射线或紫外线照射等)或化学法(过氧化物或有机硅交联)使线型聚乙烯成为网状或体型的交联聚乙烯。其中有机硅交联法工艺简单,操作费用低,且成型与交联可分步进行,宜采用吹塑和注射成型。交联聚乙烯的耐热性、耐环境应力开裂性及机械性能均比聚乙烯有较大提高,适于作大型管材、电缆电线以及滚塑制品等。   聚乙烯的共混改性 将线型低密度聚乙烯和低密度聚乙烯掺混后,就可用于加工薄膜及其他制品,产品性能比低密度聚乙烯好。聚乙烯和乙丙橡胶共混可制得用途广泛的热塑性弹性体。   茂金属聚乙烯  茂金属聚乙烯是一种新颖热塑性塑料,是90年代聚烯烃工业最重要的技术进展,是继LLDPE生产技术后的一项重要革新。由于它是使用茂金属(MAO) 为聚合催化剂生产出来的聚乙烯,因此,在性能上与传统的Ziegler-Natta催化剂聚合而成的PE有显著的不同。茂金属催化剂用于合成茂金属聚乙烯独特的优良性能和应用,引起了市场的普遍关注,许多世界著名大型石化公司投入巨大人力、物力竞相开发和研究,成为聚烯烃工业乃至整个塑料工业的热门话题。   早期,茂金属催化剂用于乙烯聚合只能得到分子量为2~3万的蜡状物,而且催化活性不高,没有实用意义,因而没有引起重视和推广。直到1980年,德国汉堡大学Kaminsky教授发现用二茂基氯锆(CP2ZrCl2)和甲基铝氧烷(MAO)组合的共催化剂在甲苯溶液中进行乙烯聚合,催化剂活性能高达106g-PE/g-Zr,反应速度与酶反应速度相当。MAO是二甲基铝和水在聚合体系以外条件下合成的高齐聚度甲基铝氧烷。Kaminsky教授的发现给茂金属催化剂研究注入了活力,吸引了众多公司参与开发和研究,并取得了相当大的进展。1991年美国埃克森(Exxon)公司首次实现了茂金属催化剂用于聚烯烃工业化生产,生产出第一批茂金属聚乙烯(mPE),其商品名是“Exact”。  茂金属聚烯烃中以mPE的发展最快和较成熟,主要品种为线型低密度聚乙烯(LLDPE)和甚低密度聚乙烯(VLDPE)。mPE有两个系列,一类是以包装领域为主要目标的薄膜用品级,另一类是以辛烯-1为共聚单体的塑性体,称为POP(Polyolefine Plastmer)。mPE薄膜品级具有较低的熔点和明显的熔区,并且在韧性、透明度、热粘性、热封温度、低气味方面等明显优于传统聚乙烯,可用于生产重包装袋、金属垃圾箱内衬、食品包装、拉伸薄膜等。   目前,茂金属线型低密度聚乙烯消费量占线型低密度聚乙烯总消费量的15%左右,预计到2010年这一比例将达到22%。据统计,目前世界上茂金属聚乙烯年产量约为1500多万吨,其中用于食品包装领域的产品约占总消费量的36%,非食品包装约占47%,其他方面(医药、汽车和建筑等)约占17%。   聚乙烯在合成树脂中产量最大、发展最快、品种开发最活跃,能否实现聚乙烯的高性能化,很大程度上取决于催化剂的性能。茂金属催化剂具有优异的催化共聚能力,它能使大多数共聚体与乙烯共聚,并且能够使极性单体催化聚合,而使用传统催化剂很难实现;在环烯聚合方面,传统催化剂只能开环聚合,而用茂金属催化剂能双键加成聚合。   因为许多发达国家纷纷采用茂金属线型低密度聚乙烯替代常规的线型低密度聚乙烯,今后茂金属线型低密度聚乙烯的年均消费增长率将高于线型低密度聚乙烯,达到15%。未来发达国家线型低密度聚乙烯产量增长的近一半将来自于茂金属线型低密度聚乙烯,预计美国市场茂金属线型低密度聚乙烯需求量将增长至2009年的134万吨。

都江堰水利工程原理是什么?

都江堰水利工程原理是流量控制的原理。从总体上看,都江堰的建造结构极为简单。它主要由三部分组成:宝瓶口(进水)、鱼嘴(分水)和飞沙堰(泄洪)。建造宝瓶口之后,岷江被分流为两条江水,东边的一部分江水可以灌溉成都平原。这样在枯水期,大部分江水会流入内江,而在汛期,多余的江水会从外江流走。进入内江的水,之后会进入第二道分水设施飞沙堰。都江堰的其他情况简介。都江堰工程的创建,没有人为地去破坏自然资源,而是因地制宜充分利用,把自然资源的特点和人类生活的需要结合起来,把劣势变为优势,使自然与人为高度协调统一。都江堰在这种顺水而治的思想指导下获得了巨大成功,这是全世界迄今为止仅存的一项古代时期的伟大生态水利工程。

蒸汽双效型溴化锂吸收式冷水机组工作原理是什么?

蒸汽双效溴化锂吸收式冷水机组基本原理:日常生活中,我们都有这样的常识,把酒精涂在皮肤上会有凉爽的感觉,这是因为酒精蒸发时吸取皮肤上热量的缘故。实际上不仅是酒精,任何一种液体在蒸发成汽体的过程中,都要吸收周围的热量。 另一方面,我们知道液体蒸发 (沸腾) 温度与其相应的压力有关,例如:一个大气压下,水的蒸发温度为100℃,而在0.00891大气压时,它的蒸发温度就降低为5℃了。可见,水的蒸发温度随压力的降低而降低。这样,只要给我们创造一个压力很低,或者说真空度很高的空间,并让水在其中蒸发,就能制出与这个低压相应的低温水了。溴化锂吸收式冷水机就是利用上述原理,让水在压力很低的蒸发器中蒸发、吸热,制出低温冷媒水的。显然,为使蒸发器中的蒸发、吸热过程不断的进行,必须不断的补充蒸发掉的水,并不断带走蒸发后的水蒸汽,这一功能就是依靠溴化锂溶液的特性来实现的。
