磷被

White phosphorus is a common allotrope of the chemical element phosphorus which has found extensive military application as an incendiary agent, smoke-screening agent, and as an antipersonnel flame compound capable of causing serious burns.

白磷属于磷元素的一种同素异形体，这种化学物质被广泛应用于军事燃烧弹，烟幕弹的制作中，其杀伤性燃烧混合物可以造成严重的烧伤。

This capacity limit is based on MDE regulations governing the allowable load of nitrogen, phosphorous, and other pollutants in treated wastewater that is discharged into Antietam Creek.

这个处理能力主要是根据马里兰德环境署的法规设计的，该法规规定了排放到安提坦河的被处理废水的氮磷和其他污染物的负荷。

In addition, silicon-germanium is a less expensive material than the compound semiconductors such as gallium arsenide or indium phosphide that have long been used in radar systems.

此外，硅锗是一种不太昂贵的材料比化合物半导体，如砷化镓或磷化铟，长期被用于雷达系统。

UV-Vis spectra show that the absorbance values at characteristic wavelengths of the multilayer films increase almost linearly with the number of chitosan/PTA bilayers, suggesting that the deposition process is regular and highly reproducible from layer to layer. XPS and FTIR spectra confirm the incorporation of chitosan and PTA into the films. AFM images indicate that the surface of the multilayer films is rough. The result of CV shows that the multiplayer films maintain good electrocatalytic activity of phosphotungstate acid.

UV-Vis结果显示多层膜在特征吸收峰处的吸光度数值随膜双层数增加逐渐增大，呈良好的线性关系，表明多层膜是均匀组装的；XPS和FTIR结果证实了壳聚糖和磷钨酸被组装到膜上，AFM图形显示膜表面有一定的粗糙度，CV结果说明多层膜保留了磷钨酸的电化学性质。

Molybdophopsphoric Acid Catalysis in the Oxidative Cleavage of Olefins by the Hydrogen Peroxide Oxidative cleavage of the double bond could be catalyzed by H_3PMo_(12)O_(40) using H_2O_2 as oxidant, various trisubstituted olefins were oxidized to aldehydes or ketones in high yields. The system was not satisfied for electron-deficient olefins such as trans-(2-nitrovinyl) benzol or chalcone. The reaction of aliphatic olefins did not occur under the same conditions.

二、磷钼酸催化过氧化氢对烯烃的氧化断裂反应用过氧化氢(30％)作为氧化剂，磷钼酸可以催化氧化碳碳双键的断裂反应，三取代的烯烃被氧化生成醛或酮，产率较高；此体系对于缺电子烯烃如查尔酮，不饱和硝基化合物的断裂反应效果较差，脂肪族烯烃在此体系下的氧化并不发生。

Unhydrolyzed extract is difficult to be utilized by fungi used in the experiment because the Arabinogalactan is main composition in the extract, but the fungi can use the sugars in hy-drolyzed extract with the addition of Nitrogen, phosphrus, etc.

未经水解的提取液主要含有阿拉伯-半乳聚糖，难以被试验菌种利用；水解后添加必要的氮、磷等营养物质，被试菌种可利用其中的单糖生产单细胞蛋白。

In the past, polyphosphate sodium and other kinds of phosphate were of high cost in production and they caused a great damage to the surface water by the phosphor element because of the overcommit of scour.

三、项目概况：本项目所生产的4A沸石，在业内被称作代磷助剂，是洗涤剂的重点组成部分，发挥漂白、清污的作用，以往洗涤剂中聚磷酸钠及其他磷酸盐，不仅造价高，而且由于过量使用洗涤剂，已经造成了磷无素对地表水的严重危害。

Firstly, the acute cytotoxicity of profenofos on FG-9307 cells was studied, it was found that the cell growth rate was markedly reduced by profenofos at all the concentrations tested; and that the fine structures of the cells were also altered by profenofos, as evidenced by dilation of nuclear membranes and mitochondria cristae, and presence of enlarged lysosomes with engulfed organelles and numerous vacuoles in the cytoplasm.

丙溴磷对FG-9307的急性细胞毒性研究结果发现：1）在所有实验浓度下，细胞的生长速度均受到抑制。2）细胞的超微结构被丙溴磷所改变，最明显的特征则是线粒体损伤严重，嵴肿胀，部分溶解破裂；核膜肿胀，有溶解；细胞内的电子密度高的溶酶体增多；内质网的膜溶解，核糖体从粗面内质网上脱落下来，游离于胞质中。

Now they are often silted up, polluted with pesticides, metals and phosphorus, or built on.

而现在这些水槽不是被淤塞了，就是被农药、重金属和磷所污染，要么就是被开发搞建设了。

Specialty lamps for diazo-printing reprography, lithography, insect traps, photochemical and curing

当放电灯被用作含磷仿日晒灯、或二氮化合物列印、平版印刷、捕虫器，以及含磷

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

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
