Because the carbonyl in its structure is with strongly absorb-electron effect, so it is a kind of non-proton polarity solvent with high boiling point, high flash point and low melting point, use conveniently for many processing operation such as filtration, distillation, solvent extraction, and so on; it is with very low toxicity, so the harm to human body is inappreciable, and reduce the environment pollution; due to its very strong dissolvability, it can dissolve organic matter, inorganic matter, resin, polymer, etc., and activate all kinds of reagent, mix to dissolve the other high boiling point solvents; it is with very good stability, it is stable under the hot strong alkali and acidity condition, it is with water-resistance and light, oxygen stability.

246℃ m.p：—20℃闪点121℃ flash point： 121℃分子式：C6H12N2O molecular formula： C6H12N2O 分子量128.18 molecular weight： 128.18 二、DMPU的化学性质 Chemical character of DMPU 其结构中由于羰基具有强烈的吸电子效应，因而它是一种非质子的极性溶剂，具有高沸点、高闪点、低熔点，在过滤、蒸馏、溶剂萃取等工艺操作中使用方便；毒性极低，对人体危害微不足道，也减少了对环境的污染；由于它具有极强的溶解性，能溶解有机物、无机物、树脂、聚合物等，并对各种试剂具有活化性质，还能与其它高沸点溶剂混溶；具有极好的稳定性，在热的强碱和酸性条件下都很稳定，还具有耐水性及对光、氧的稳定性。

Therefore, a new theory of space vector reactive power is presented in this dissertation, where instantaneous reactive current and instantaneous active current are defined, based on the new theory.

作为治理电网污染、提高电网稳定性和改善电能质量的一项关键技术，有源滤波技术已成为电力电子技术应用中的一个比较新的研究课题。

With the development of microelectronic industry, new techniques are urgently required to lower the pollution, simplify and the producing process of electronic circuit, and miniaturize the products.

随着微电子业的发展，要求有新的技术出现来满足电子线路的制作向低污染、简单化、细微化等方向发展。

Mol·L~(-1) individually and also with both heavy metals present. Plasmolysis, concentrated cytoplasm, disappear ance of the cristae of mitochondria, ambiguity of framework and destruction of mitochondria envelope were all symptoms of root cells under Cu stress; hollowing cells was also found in Cd treatment, and there existed some different granule in these hollowing cells.

铜使根细胞产生质壁分离、细胞质浓缩、部分细胞空泡化，使线粒体脊突消失、结构模糊、外膜破坏；镉使根细胞空泡化，并在部分空泡化的细胞里产生大小不等的颗粒状物；铜、镉交互污染使根细胞受害程度加深，并兼有两者的受害症状特征：线粒体结构彻底破坏、空泡化细胞里的颗粒物更大电子密度更高、质壁分离现象更普遍、质膜上的颗粒物沉淀更大。

To the extent that electronic commerce enables people to telecommute, everyone benefits from the reduction in commute caused t raffic and pollution.

在一定的程度上电子商务能使人们远程交流，每个人都能从造成交通拥堵和污染的交流减少中获利。

A hydroponical experiment was carried out to study the toxicity of copper, cadmium and their combined pollution on ultrastructure of Commelina bengalensis Linn. Transmission Electron Microscope was used to investigate the effect of heavy metal on ultrastructure of different parts of plants.

为了解铜、镉对泡泡草根、茎、叶细胞亚显微结构的毒害及作用位点，以期为进一步研究鸭跖草属植物的耐重金属机理提供理论基础，本文通过透射电子显微技术研究了75 μmol·L-1铜和50μml·L-1镉及其交互污染对泡泡草根、茎、叶细胞超微结构的影响和铜、镉在细胞中的分布。

It's a perfect substitute of petrolic products and extensivly applied for injection, squeeze film, blown, fabric industry and area.

聚乳酸是一种生物降解环保材料（在堆肥的条件下，分解成二氧化碳和水），其不仅不受石油危机的影响，还可以解决白色污染问题，是石油基产品的良好替代品；广泛的应用在注塑、吹膜、挤片、纤维等行业和领域，如用来生产电子产品、玩具、文具、食品包装和其它一次性的用品等。

The results showed that under the given experimental conditions,the surface layer with richiron and poor copper was formed in the surface worn region of the semimetallic friction material,the depth of organic ingredient pyrolysis caused by friction heat in worn surfaces was atout 0.35mm; the semimetallic friction material containing 15%-20%of Cu had better wear-resistance,and can form a even and continuous transfer film of copper; crack peeling was the importantmechanism of the counterpart.

半金属摩擦材料具有摩擦系数稳定，耐磨性好，对环境污染小和对偶件表面损伤小等优点，但其在摩擦热和界面应力等因素作用下，表层会发生弹性变形，塑性变形，元素扩散，组分转移和摩擦化学反应等现象，因此，利用扫描电子显微镜X射线能量色散谱和差热－热重分析，对铜纤维增强的半金属摩擦材料与灰铸铁滑动摩擦表面层的特性作了分析研究，考察了表面层特性对摩擦损行为的影响。

The split between the two groups can hardly be papered over.
