Phosphine(PH3)is an important electronic specific gas which is mainly used in fields of N-type semiconductor doping,ion implement and chemical vapor deposition etc.

磷化氢在电子工业中主要用作外延硅半导体的一种n型掺杂剂，在化学气相沉积和离子注入中被用作一种磷源，在发光二极管用磷砷化镓膜的生产中也占有重要地位。

So, eutrophication lake water may be one source of phosphine taking part in phosphorus circulation.

结果表明：富营养湖泊水体是磷化氢参与磷的生物地球化学循环的一个汇。

Therefore, it is of great significance to make thorough study on its distribution characters in marine sediments and the transforming mechanism of phosphine so that evidences would be provided for its function in the phosphorus biogeochemical recycle.

开展磷化氢在海洋沉积物中的分布特征、磷化氢与其他形态磷化物之间的转化机制的研究，对于弄清磷化氢在磷的生物地球化学循环中的作用和地位具有重要的科学意义。

The experts also simulated the phenomenon of natural fire in Luo Maozai's home: the phosphoreted mineral was decomposed into the gas of phosphoreted hydrogen under the condition of bacteria. The gas of phosphoreted hydrogen burns spontaneously under given conditions of moist air and then ignites the methane in the air which comes from the mouse holes.

专家组成功地模拟了罗家的&自燃&现象：含磷的矿物质在有细菌和具备还原性条件下分解成磷化氢气体，而磷化氢气体在一定潮湿的空气环境下自燃，继而引发空气中通过老鼠洞挥发出来的甲烷体燃烧。
