磷化氢

Was founded in 1993, after reorganization of assets in 2003 as "phosphide", more than 500 million fixed assets, the existing 150 staff, of whom technical staff of more than 20, are specializing in the production of phosphate (sodium pyrophosphate, disodium hydrogen phosphate, sodium hexametaphosphate, potassium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate) enterprise.

河南省焦作市磷化实业有限公司（原武陟县兴璋化工有限公司）建于1993年，后经2003年资产重组为"磷化"，公司固定资产500多万，现有职工150人，其中技术人员20多名，是专业生产磷酸盐（焦磷酸钠，磷酸氢二钠，六偏磷酸钠，磷酸二氢钾，磷酸氢二钠，磷酸三钠）企业。

Phosphine generally require long exposure periods, whereas methyl bromide and sulfuryl fluoride provide a rapid fumigation that can be completed in less than 4 days, often within 24 hours.

磷化氢一般需要较长的密闭时间，而溴甲烷和硫酰氟则适合快速熏蒸，可在不到4天之内完成熏蒸工作，一般在24小时内完成。

After this, the experiment proved that why the natural fires occurred over 100 times is that the phosphoreted hydrogen burns itself and ignites the methane.

此后，经过实验证明，原来这是由于磷化氢自燃引燃甲烷所致。

The studies on mixture fumigation of phosphine with carbon dioxide to control Sitophilus oryzae and Sitophilus zeamais were carried out at three different temperature 35℃、40℃and 45℃.

本实验在 35℃、 4 0℃和 4 5℃ 3个不同温度条件下用磷化氢和二氧化碳混合熏蒸防治玉米象和米象。

The average concentration in No.1 warehouse was reduced by 5.3%in each day when fumigating for seven day.

与无薄膜的全仓环流熏蒸试验相比，膜下环流熏蒸磷化氢浓度达到均匀的时间短；气密性好，熏蒸时取得的Ct值大，杀虫效果更好。

The supported WP catalysts showed considerable activity in HDS reaction of dibenzothiophene and HDN reaction of quinoline. The ibenzothiophene HDS activity and quinoline HDN activity of the spported WP catalysts synthesized by co-impregnation method was better than that synthesized by mixing method. The HDS and HDN activities of 25～30% WP catalysts synthesized by co-impregnation method and reduced at 650～750℃ were better than those of the corresponding sulfurized catalyst.

负载型WP催化剂具有较好的二苯并噻吩加氢脱硫和喹啉加氢脱氮活性，共浸渍法制备的磷化钨催化剂二苯并噻吩加氢脱硫和喹啉加氢脱氮活性要高于混合法制备的磷化钨催化剂。650～750℃还原制备的负载量25～30%的浸渍法磷化钨催化剂具有较高的二苯并噻吩加氢脱硫和喹啉加氢脱氮活性，高于相应的硫化态催化剂。

The phosphine concentration and distribution were mainly affected by the organic phosphorous, the redox potential and the sediment composition.

磷化氢在沉积物中的含量分布主要受沉积物中有机磷含量、氧化还原电位及沉积物的组成等多种因素共同的影响。

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。
