Acquired immunodeficiency syndrome (AIDS) is an AIDS virus,that the human immunodeficiency virus (human immunodeficiencyvirus.called HIV) dormant in the human body and the human immune function and occurrence of a variety of human tumors and incurable infection,finally led to the deaths of a serious infection diseases.AIDS is the generic AIDS medicine, "acquired immune deficiency syndrome," Acquired Immune Deficiency Syndrome first word acronym.Expression of the name of the concept of AIDS, AIDS, we can learn from the three clearly defined :Acquired : etiology is acquired at birth rather than have the access.Said : defects in the immune pathogenesis.The damage was mainly caused by the body"s immune system and cause the immune system to reduce the protective function loss.Immune deficiency is a common feature : a.. B. increased susceptibility to infection. Prone to cancer;c. The clinical and pathological features diversity.SARS : at the clinical symptoms, as a result of defects in various immune system against opportunistic infections,Tumors arising from the complex syndrome.AIDS is a retrovirus infection caused by the body"s immune defense system diseases.In a normal human body, the immune system plays a good body of the "defensive",various pathogens to resist the attack.But one HIV-infected, a good body defense system will be destroyed, defense dysfunction.Then microbial pathogens and thus able to drive straight into the opportunity Hematogenous wounds and broken.In addition, the number of abnormal body cells, such as cancer cells, also flew rapid growth, large population,develop into all types of cancer.In other words, the immune system of AIDS patients is mainly expressed serious injury, the body resistance decreasedSome serious infections and even induced a rare carcinoid tumor.AIDS originated in Africa, young people are also in Haiti in 1979 and distributed by the immigrants into the United States.June 5, 1981, the United States Centers for Disease Control in Atlanta.first in the "Morbidity and Mortality Weekly," a brief introduction to the five cases they found that the history of AIDS patients.1982 will be officially named the disease "AIDS."Soon after, the rapid spread of AIDS in the continent.In June 1985, in Shanghai by a young American male tourists from Argentina AIDS patient cured invalid.died in the country, this is the first case of AIDS in China.AIDS has been in China since 1985 and nearly 10,000 people enter the AIDS virus carriers.According to speculation in the next few years : AIDS trend is downward trend in the developed countries is,while for developing countries was a sharp upward trend.Known as "contemporary plague" and "super cancer" AIDS has caused the World Health Organization (WHO) and national governments attach great importance to it,The inputs of both staff and financial resources to be top priority, China has been included in Category B diseases.health surveillance of infectious diseases and one territory.

翻译:艾滋病(AIDS)是一种由艾滋病病毒,即人体免疫缺陷病毒(human immunodeficiencyvirus,简称HIV)侵入人体后破坏人体免疫功能,使人体发生多种不可治愈的感染和肿瘤,最后导致被感染者死亡的一种严重传染病。AIDS是艾滋病的医学全称“获得性免疫缺陷综合症”Acquired Immune Deficiency Syndrome的英文字头缩写词。这个命名表达了艾滋病的完整概念,从中我们可以了解到艾滋病的三个明确定义:获得性:表示在病因方面是后天获得而不是先天具有的。

免疫缺陷:表示在发病机理方面,主要是造成人体免疫系统的损伤而导致免疫系统的防护功能减低、丧失。

免疫缺陷病的共同特点是:a.对感染的易感性明显增加;b.易发生恶性肿瘤;c.临床及病理表现多样化。

综合症:表示在临床症状方面,由于免疫缺陷导致的各个系统的机会性感染、肿瘤而出现的复杂症状群。

艾滋病是一种由逆转录病毒引起的人体免疫防御系统方面的疫病。人体处于正常状态时,体内免疫系统对机体起着良好的“防御”作用,抵抗各种病原体的袭击。一但受艾滋病病毒感染之后,人体的这种良好防御系统便会受到破坏,防御功能减退,因而这时病原体及微生物得以乘机经血行及破损伤口长驱直入。此外,身体中一些不正常的细胞,例如癌细胞,也同样乘机迅速生长、大量繁殖起来,发展成各类癌瘤。也就是说,艾滋病病人主要表现为免疫系统受到严重损伤,机体抵抗力下降,以至诱发严重感染和一些少见的癌瘤。

艾滋病发源于非洲,1979年在海地青年中也有散发,后由移民带入美国。1981年6月5日,美国亚特兰大市疾病控制中心,首次在《发病率与死亡率周刊》上简要的介绍了他们发现的五例艾滋病病人的病史。1982年正式将此病命名为“艾滋病”。以后不久,艾滋病迅速蔓延到了各大洲。1985年6月,由上海入境的一名美籍阿根廷青年男性游客因艾滋病住院,治愈无效,死于我国境内,这是出现在我国的首例艾滋病。艾滋病自1985年进入我国至今已有近万人为艾滋病病毒携带者。据有关部门推测,在今后几年内艾滋病发展趋势是:发达中国家是呈下降趋势,而发展中国家则呈急剧上升趋势。

被称为“当代瘟疫”和“超级癌症”的艾滋病已引起世界卫生组织(WHO)及各国政府的高度重视,无论是人员和经费的投入均放在首位,我国已将其列入乙类法定传染病,并为国境卫生监测传染病之一。

晶体缺陷是什么?

晶体缺陷(crystal defects)是指晶体内部结构完整性受到破坏的所在位置。按其延展程度可分成点缺陷、线缺陷和面缺陷。晶体结构中质点排列的某种不规则性或不完善性。又称晶格缺陷。表现为晶体结构中局部范围内,质点的排布偏离周期性重复的空间格子规律而出现错乱的现象。①点缺陷,只涉及到大约一个原子大小范围的晶格缺陷。它包括:晶格位置上缺失正常应有的质点而造成的空位;由于额外的质点充填晶格空隙而产生的填隙;由杂质成分的质点替代了晶格中固有成分质点的位置而引起的替位等。在类质同象混晶中替位是一种普遍存在的晶格缺陷。②线缺陷,是沿着晶格中某条线的周围,在大约几个原子间距的范围内出现的晶格缺陷。位错是其主要的表现形式。具有位错的晶体结构,可看成是局部晶格沿一定的原子面发生晶格的滑移的产物。滑移不贯穿整个晶格,晶体缺陷到晶格内部即终止,在已滑移部分和未滑移部分晶格的分界处造成质点的错乱排列,即位错。这个分界外,即滑移面在晶格内的终止线,称为位错线。

晶格缺陷的晶格缺陷lattice defects

在实际的晶体中,由于晶体形成条件、原子的热运动及其它条件的影响,原子的排列不可能那样完整和规则,往往存在偏离了理想晶体结构的区域。这些与完整周期性点阵结构的偏离就是晶体中的缺陷,它破坏了晶体的对称性。缺陷对晶体的物理性质具有极其重要的影响,可分为面缺陷、线缺陷和点缺陷三种。其中晶粒间界、堆垛层错和孪晶间界属于面缺陷,晶粒间界指多晶体中晶粒之间的交界面。堆垛层错是指晶体中原子面的堆垛顺序出现反常而造成的缺陷,它只影响层错面附近晶体结构,并不影响其他区域的原子层堆垛顺序。孪晶是指晶体中相毗邻的两部分互为镜像。线缺陷主要是指位错,位错的存在对晶体的力学性质机翼各种物理性质都有影响。除了三种缺陷外,晶体中还存在很多其他缺陷,如在对无位错单晶研究中发现晶体中存在微缺陷,在制作无位错硅单晶中发现了密度很大且线度很小的缺陷群。 最常见的点缺陷是“晶格空位”和“间隙原子”。当晶格中的某些原子由于某种原因(如热振动的偶然偏差等)脱离其晶格结点而转移到晶格间隙时会造成点缺陷。空位,填隙,替位; 即晶格中的“位错线”,或简称位错,可视为晶格中一部分晶体相对于另一部分晶体的局部滑移而造成的结果,滑移部分与未滑移部分的交界线就是位错线。位错,刃位错,螺旋位错,混合位错; 即晶界和亚晶界。这两种晶格缺陷都是因晶体中不同区域间的晶格位相过度造成的。平移界面,堆垛层错,晶界,亚晶界。

谁能告诉我 合成体 的概念,谢谢!

智能材料的时代 展望21世纪的高分子化学 高分子化学作为化学的一个分支,同样也是从事制造和研究分子的科学,但其制造和研究的对象都是大分子,即由若干原子按一定规律重复地连接成具有成千上万甚至上百万质量的、最大伸直长度可达毫米量级的长链分子,称为高分子、大分子或聚合物。既然高分子化学是制造和研究大分子的科学,对制造大分子的反应和方法的研究,显然是高分子化学的最基本的研究内容。 高分子化学的发展历程 早在19世纪中叶高分子就已经得到了应用,但是当时并没有形成长链分子这种概念。主要通过化学反应对天然高分子进行改性,所以现在称这类高分子为人造高分子。比如1839年美国人 G oodyear发明了天然橡胶的硫化;1855年英国人 P arks由硝化纤维素(guncotton)和樟脑(camphor)制得赛璐珞(celluloid)塑料;1883年法国人 d e Chardonnet发明了人造丝 r ayon等。可以看到正是由于采用了合适的反应和方法对天然高分子进行了化学改性,使得人类从对天然高分子的原始利用,进入到有目的地改性和使用天然高分子。 回顾过去一个多世纪高分子化学的发展史可以看到,高分子化学反应和合成方法对高分子化学的学科发展所起的关键作用,对开发高分子合成新材料所起的指导作用。比如70年代中期发现的导电高分子,改变了长期以来人们对高分子只能是绝缘体的观念,进而开发出了具有光、电活性的被称之为“电子聚合物”的高分子材料,有可能为21世纪提供可进行信息传递的新功能材料。因此当我们探讨21世纪的高分子化学的发展方向时,首先要在高分子的聚合反应和方法上有所创新。对大品种高分子材料的合成而言,21世纪初,起码是今后10年左右,metallocene催化剂,特别是后过渡金属催化剂将会是高分子合成研究及开发的热点。活性自由基聚合,由此而可能发展起来的“配位活性自由基聚合”,以及阳离子活性聚合等是应用烯类单体合成新材料(包括功能材料)的重要途径。对支化、高度支化或树枝状高分子的合成及表征,将会引起更多的重视。因为这类聚合物的结构不仅对其性能有显著的影响,而且也可能开发出许多新的功能材料。 高分子化学的创新研究 高分子化学作为材料科学的一个支撑学科,其发展事实已经表明,化学方法制造出来的聚合物,当其作为高分子材料使用时,其作用和功能的发挥,不只是单靠由化学合成决定的一级结构,即分子链的化学结构,还要靠其高级层次上的结构,即靠高分子聚集体中由物理方法得到的、非化学成键的分子链间的相互作用的支撑和协调。有的时候这种高分子聚集体和这些高级结构,如相态结构和聚集态结构,对高分子材料、尤其是高分子功能材料的影响更为明显。这种物理方法得到的非化学成键的、分子链间的相互作用的形成,可以通过所谓的物理合成或物理组合的方法来实现,即用物理方法将一堆分子链依靠非化学成键的物理相互作用,联系在一起成为具有特定结构,如超分子结构的高分子聚集体,从而显示出特定的性质。因此21世纪的高分子化学除了制造和研究一个分子链,还应包括制造和研究“一堆”分子链,在化学合成之外包括物理合成,在分子层次的研究之外还要有分子以上层次的研究。 因而以精确设计和精确操作为基本思路来发展和完善化学和物理的这种结合,也是21世纪的高分子化学研究,尤其是高分子材料研究中一种值得注意的方向。 高分子材料的纳米化 现有的高分子化学反应中原子重新排列键合的反应空间一般都较原子尺寸大得多,因此化学反应是在一非受限空间进行的。如果在一有限空间或环境中,如纳米量级的片层中,小分子单体因为与片层分子的物理相互作用而被迫在此受限空间中进行某种方式和程度的排列,然后再发生单体的聚合时,聚合产物的拓扑结构既不可能是受限空间的完全复制,又不同于自由空间中得到的情况。我们从这种受限空间的聚合反应也许可以提出高分子纳米化学的概念。化学的制备对象从来都是纳米量级的原子或分子,但由于其方法不够精细,不能在纳米尺度上实现原子或分子的有目的的精确操纵,因此即使目前可以做到分子的精确设计也较难实现,从而使得化学合成给人以粗放的感觉。高分子的纳米化学,就是要按照精确的分子设计,在纳米尺度上规划分子链中的原子间的相对位置和结合方式,以及分子链间的相互位置和排列,通过纳米尺度上操纵原子、分子或分子链,完成精确操作,实现纳米量级上的高分子各级结构的精确定位。从而精确调控所得到的高分子材料的性质和功能。高分子纳米化学的目的就是实现高分子材料的纳米化。 高分子材料的纳米化可以依赖于高分子的纳米合成,这既包括分子层次上的化学方法,也包括分子以上层次的物理方法。利用外场包括温度场、溶剂场、电场、磁场、力场和微重力场等的作用,在一确定的空间或环境中像搬运积木块一样移动分子,采用自组装、自组合或自合成等方法,靠分子间的相互作用,构建具有特殊结构形态的分子聚集体。如果再在这种分子聚集体中引发化学成键,则能得到具有高度准确的多级结构的高分子。通过这种精确操作的高分子合成,可以准确实现高分子的分子设计。 高分子材料的纳米化还可以通过成型加工的方式得以实现,即在成型加工过程中控制高分子熔体的流动,调节高分子的结构形态从而控制使用性质。高分子材料的纳米化研究不仅应包括纳米化制备方法,还不应忽略高分子材料的纳米结构的观察和纳米性质的测量。因为结构和性能决定材料的使用价值。而高分子材料的纳米化的结果,是使得表面层上和界面层上的结构和性能表现出特异性,这部分也是由于在表面和界面的尺寸限制下,高分子材料的相结构和形态发生突变所致。因此需要开展表面层上和界面层上的相结构、相行为及分子链动力学的研究,建立相应受限条件下的高分子材料的构效关系。采用的研究方法中,计算模拟和扫描探针技术等都是十分有用的。 智能材料中的高分子化学 如果说20世纪的人类社会文明的标志是合成材料,那么下个世纪将会是智能材料的时代。在这个智能材料的时代,高分子化学同样承担着不可替代的作用。智能材料是材料的作用和功能可随外界条件的变化而有意识的调节、修饰和修复。已经知道高分子具有软物质的最典型的特征,即易于对外场作出响应。软物质(soft matter)是指易于发生变形的那类物质。软物质不仅在一般的剪切作用下可发生畸变和流动,而且小的热涨落也会对其性质带来重要的影响。软物质包括高分子、生物大分子、液晶、胶体及乳胶和微乳胶这类两亲物质等。软物质在物质科学的研究中被越来越多的提及,产生了研究软物质的专门学科———软物理(soft physics)。软物质可以用来研究凝聚态物理学中的一些核心问题,如对称性(symmetry)、低能量激发(low-ener- gy excitation)和拓扑缺陷(topological defects)之间的联系。软物质研究的另一方面的意义是软物质的应用。前面提及的软物质所包括的那些物质,实际都是有着明显的使用价值。也许正是因为如此,最近又出现了材料科学变软的提法。软物质的研究虽然目前主要还是在凝聚态物理的学术圈中进行,但其研究领域则涉及数学、化学、化工、材料、生物及其交叉学科,被认为是下个世纪物质科学及其相关学科中的重点研究内容之一。因此在高分子化学的研究中,引进软物质的概念,利用外场的变化构建高分子材料的特殊结构,实现外场作用下高分子材料的作用和功能的实时调制,应是高分子智能材料研究的重要内容。 广义上的智能材料也应包括生命材料。由于生物大分子和合成高分子都属于软物质,因此软物质科学的研究也有助于高分子生命材料的研究,虽然目前合成高分子也能模仿蛋白质分子的自组装,但却没有蛋白质分子那样的生命活性。这是因为合成高分子的分子链缺少确定的序列结构,不能形成特定的链折叠。如果在合成高分子膜的表面附着上蛋白质分子或有特定序列结构的合成高分子,研究这些表面分子折叠的方法、规律、结构和活性,形成具有生命活性功能,比如排斥和识别功能的软有序结构,再通过化学环境、温度和应力等外场来调节这些软有序结构,从而控制外界信号向合成膜内的传递,实现生物活性的形成和调控,尝试合成高分子生命材料。 高分子化学对资源的依赖 化学是制造和研究物质的科学。调节原子和分子在物质中的组合配置,控制物质的微观性质、宏观性质和表面性质,就可能使某种物质满足某种使用要求,因而这种物质就能作为材料来使用。因此材料的制备对资源的依赖性和材料的使用与环境的协调性,就成为化学研究中一个独特而又十分重要的方面。当代高分子合成材料依赖于石油这种化石资源。由于石油的生成是一个漫长的地质过程,同时石油又是当代人类社会的主要能源,石油资源正日益减少而又无法及时再生,因此寻找可以替代石油的其它资源,则成为21世纪的高分子化学研究中的一个迫切需要解决的问题。其解决的途径可以是天然高分子的利用,也应包括合成无机高分子的探索。 21世纪利用源于植物的高分子,显然不同于上个世纪对天然高分子的简单使用。结合基因工程的方法,促使植物产生出更多的可直接使用的天然高分子,或可供化学合成用的高分子单体。采用生物催化剂或菌种,将天然的植物原料,如淀粉、木质素和纤维素等,合成为与有机高分子相似的结构或性质更优异的高分子。这些由植物资源获得的高分子,不仅扩大了合成高分子的原料来源,而且得到的合成高分子还具有环境友好的特征,可以是生物降解的,可以是焚烧无害的,可以是循环再生的。目前来源于石油资源的合成高分子,其主链上的原子以碳为主兼有少量氮、氧等原子,因而称为有机高分子。无机高分子则泛指主链原子是除碳以外的其它原子。按元素性质判断约有四五十种元素可以形成长链分子。目前报道的有全硅主链、磷和氮主链、硅氧及硅碳主链、全镓和全锡主链,硫磷氮和硫碳主链、含硼主链、以及含过渡金属主链的无机高分子。其中主链全部是硅原子且具有有机侧链的聚硅烷应是值得注意的一种无机高分子。这既是由于硅是地球上储量最丰富的元素,又是因为聚硅烷既可用作结构材料又可用作功能材料。无机高分子的研究充分体现出了单体分子的选择和化学反应的控制,是如何决定高分子材料的性能和功能的。 高分子化学的可持续发展 研究高分子合成材料的环境同化,增加循环使用和再生使用,减少对环境的污染乃至用高分子合成材料治理环境污染,也是21世纪中高分子材料能否得到长足发展的关键问题之一。比如利用植物或微生物进行有实用价值的高分子的合成,在环境友好的水或二氧化碳等化学介质中进行化学合成,探索用前面提到的化学或物理合成的方法合成新概念上的可生物降解高分子,以及用合成高分子来处理污水和毒物,研究合成高分子与生态的相互作用,达到高分子材料与生态环境的和谐等。显然这些都是属于21世纪应当开展的绿色化学过程和材料的研究范畴。 高分子化学的发展方向 材料是人类社会文明发展阶段的标志。当代材料研究具有以下几个特点:传统材料(钢铁、陶瓷和有机高分子)之间的界限变得越来越模糊而融合变得更明显,如无机高分子和有机/无机杂化材料的应用等;通用材料与功能材料之间的相互渗透变得越来越明显,更多的通用材料包括结构材料会同时具有某些功能特性,而功能材料也会显现通用材料的性能;材料中原子和分子组合配置的精确设计和精确制备,及纳米尺度上结构和性质的观察和测量变得更重要,如化学制备智能材料、生命材料和单分子器件等;材料的传统研究方法与当代信息社会提供的新技术的结合变得更必要,如计算材料科学等。这些研究表明,当代化学家们正在迎接着以智能材料及生命材料为时代文明特征的21世纪的到来。 材料的发展是与人类社会的经济发展、人类与自然界间的协调和资源的利用以及人类自身的存在和发展同步进行的。因此支撑材料发展的相关科学如化学的发展,不仅关系到材料的创新和发展,还影响到受材料支撑的国民经济和社会发展的其它领域,如农业、能源、信息、环境及人口与健康等的进步与发展

神经管畸形4维能发现吗   神经管畸形4维能发现吗,随着科技的进步,神经管的畸形在我们的生活中也能利用科技的手段达到最能接受的一种普遍情况,但是偶然性的科技也是有一定的缺陷的,那么神经管畸形4维能发现吗,下面来了解一下吧。   神经管畸形4维能发现吗1    神经管畸形4维能发现吗   四维彩超能够全方位、多角度地观察宫内胎儿的生长发育情况,早发现胎儿多种异常,如血管畸形、唇裂、心脏、骨骼发育不良等,遗传性综合征也能被及时发现。另外,四维彩超还能展示胎儿体内脏器官的实时活动图像,为揪出胎儿先天性体表畸形和先心病提供科学依据。    胎儿神经管缺陷会有胎动吗   其实胎儿神经管缺陷一般情况下是不会影响胎动的,不能根据胎动确定胎儿神经管缺陷,应该定期B超检查,检测胎儿生长发育和各个器官结构和发育状况。据统计,孕妇在怀孕过程中出现胎儿畸形的几率约为2%,畸形的胎儿常伴有残疾或严重的疾病。目前,我国对重大胎儿畸形进行孕期筛查,主要包括:21-三体综合征、18-三体综合征、开放性神经管缺陷、无脑儿、重度脑积水、某些严重的先天性心脏病等。   看了以上这么多的信息,我们知道了神经管缺陷可是很严重的健康问题,各位妈妈们都应该注意,不能掉以轻心,平时注意要好好调理好身体,保护肚子里的宝宝,一旦有什么异常,一定要及时就医治疗,避免出现更加严重的后果。   神经管畸形4维能发现吗2    神经管畸形,又称神经管缺陷(neural tube defects) ,是一种严重的.畸形疾病,神经管就是胎儿的中枢神经系统。   在胚胎的第15-17日开始,神经系统开始发育,至胚胎22日左右,神经褶的两侧开始互相靠拢,形成1个管道,称为神经管,它的前端称为神经管前孔,尾端称为神经管后孔,胚胎在24-25日及26日时,前孔及后相继关闭。胎儿神经管畸形主要表现为无脑儿、脑膨出、脑脊髓膜膨出、隐性脊柱裂、唇裂及腭裂等。   当妇女怀孕3个月之内,胚胎发育时神经管闭合过程受到影响即产生胎儿脑或脊髓发育异常,便会形成小儿神经管畸形。小儿神经管畸形(DNT)是造成孕妇流产、死胎主要原因之一,也是造成婴儿死亡和患者终身残疾的主要原因之一。既影响出生人口素质,又威胁妇女儿童身心健康,给家庭和社会造成沉重的负担。小儿神经管畸形是世界范围内的一个重要公共卫生问题,中国是世界上已知的小儿神经管畸形高发国家。目前小儿神经管畸形的防治已被高度重视。   先天性神经管畸形这种疾病在我国并不少见,已经引起了很多医学家的重视。虽然说这种疾病非常的恐怖,会给家人带来极大的痛苦,但是也并不是不可防治的。所以各位怀孕的孕妇应当保护好自己,时刻注意胎儿的情况。

六西格玛设计:如何运用DPMO进行设计分析?

如何运用DPMO进行设计分析DPMO(Defects per Million Opportunity)即每百万个机会中的缺陷数,是六西格玛管理中的一个重要概念。一、DPU(Defects per Unit)单元缺陷d——是所观测到的缺陷的频数或次数u——是所生产的单元数量二、DPO(Defects per Opportunity)每机位缺陷例如,生产1000部电话机,每一部电话机具有10个等同缺陷机会,而检测出的缺陷数为60个,那么:所以由DPO可以计算DPMO,由DPMO可计算出ZLT。上式DPMO=6000,ZLT=4.01在这个例子中,Z是长期的,通常没有ZST。这是因为收集离散数据需要花很长时间。三、DPMO与西格玛或Z的转化问题假如我们知道一个过程有2000DPMO的能力,那么这个过程的西格玛或Z值是多少呢?我们可以用NORMSINV(标准正态分布的反函数)求得:Z= NORMSINV (1-DPMO/1000000)+1.5 Z计算出来是ZLT过程的长期能力由于DPMO=2000Z=标准值(1- 2000/1000000 ) +1.5=4.37反之,我们知道一个过程有Z=5.6个西格玛的能力,那么它的DPMO又是多少呢?同样我们可用以下公式:DPMO=1000000[1-标准距离(Z-1.5)]其中:NORMSDIST是标准正态累积分布,即在标准正态曲线下指定的Z值的面积。由于Z=5.6所以DPMO=1000000[1-标准距离(5.6-1.5)]=20四、最小DPU或DPMO设计对于过程(工序)而言,工序越多越复杂。这是因为每一个过程都会影响到新产品或服务的性能。假如一个过程完成需四个工序Y1、Y2、Y3、Y4,每一道工序的合格率为Y1=99%,Y2=95.4%,Y3=97%,Y4=98%,那么全部完成这个过程的能力是多少呢?从六西格玛设计角度来考虑,系统过程越少越好,这样既减少了工序,又提高了YRT,因此提倡简约设计,即减少冗余,提高新产品或过程的可靠性。因此在六西格玛设计系统分配上要考虑简化设计的重要性。最小DPU设计,也是从提高滚动合格率YRT来考虑的。从上图可以看出DPU→O,YRT→1,最小DPU设计也是从过程的繁杂程度来考虑合格率的。因此,进行简化设计也是六西格玛设计的方向之一,即简约之美。

关于解决能源危机的英语作文

With the rapid growth of global economy and population, energy is becoming increasingly important. However, the over-reliance on non-renewable energy sources, such as oil, coal and gas, is now posing challenges to our future. Hence, addressing the energy crisis is one of the most serious issues we are facing today.Firstly, we need to develop and exploit renewable energy sources, such as solar, wind, hydro and biomass, which are sustainable and less harmful to the environment. Governments should encourage investment in renewable energy technologies by providing subsidies and tax incentives to attract private funding, and promote research and innovation in this area. Meanwhile, individual households can adopt energy-saving appliances, such as LED lights and energy-efficient air conditioners, to reduce energy consumption.Secondly, improving energy efficiency is also vital for addressing the energy crisis. We need to adopt energy-saving practices, such as turning off lights when leaving a room and using public transportation instead of private cars. Moreover, industries should adopt "green manufacturing" practices to reduce energy use and carbon emissions in their production processes.Thirdly, we should also explore nuclear energy as an alternative energy source. Although the nuclear power plant accidents in the past have been disastrous, modern nuclear technologies developed and used in some countries have proven to be much safer and more efficient. Governments should invest in developing safe and efficient nuclear energy technologies, as it provides a cleaner and more reliable energy source other than fossil fuels.Lastly, governments should develop and implement policies and regulations that encourage the transition to cleaner fuels and technologies, such as carbon taxes and emission reduction targets. Governments should also work together to establish global agreements that aim to reduce greenhouse gas emissions and promote low-carbon growth.In short, the energy crisis is a global challenge that requires concerted efforts from governments, the private sector, and individuals to find sustainable solutions. By developing sustainable energy sources, improving energy efficiency, exploring nuclear energy, implementing policies and regulations, we will be able to address the energy crisis and create a cleaner and brighter future.

拼音hun的韵母结构分析?

楼主您好,以下是我的分析,希望对你有所帮助!汉语拼音xiong为单音节,且声母、韵母齐全。其中 x 为声母,音同”西“;韵母有两个,i 和 ong,前者读音同“衣”,后者因为单独无法构成音节,所以没法用汉字标注谐音,用英式音标[??] 可以表示。如有不详尽,欢迎追问;如满意,~!
