查询词典 methane

A group of amorphous CHN films were fabricated successfully by hollow cathode plasma chemical vapor deposition with ammonia,hydrogen and methane as reacting gas.The variation of deposition rate as a function of DC voltage and reactive gas flows were studied,respectively.

采用空心阴极等离子化学气相沉积方法，以NH3/H2的混合气体及CH4气体为原料反应气体，成功地制备了非晶的CHN薄膜，研究了CHN薄膜的沉积速率与直流电压及反应气体流量的关系。

During the process of this research, the Otto configuration and KR configuration are used to proceed the special analysis on the chlorine and Halogen-methane, and through the simulative experimental investigation into the tiny variation of dielectric constants of Halogen gas, the resonant angle and depth of absorption of the to-be-investigated gas can be accurately measured. Thus, this optical measuring system can be confirmed with high sensitivity.

研究过程中，我们使用Otto组态与KR组态分别对氯气与卤族甲烷做特别的分析研究，经由卤族气体的微小介电常数差异，透过模拟实验分析后，仍然可以准确的判断出待测气体之共振角度与吸收的深度，所以利用此光学式量测系统来量测可说是具有相当之灵敏性。

Victor Gonzalez of the Volcanological and SeismologicalObservatory of Coata Rica stated that the gas is likely to bepreviously trapped methane that was released after the jolting created a fissurein the ocean floor. He also said that it is not known how long the flammablegreenhouse gas would continue to rise.

哥斯达黎加火山和地震观测站的地震学家维多萨雷斯博士指出那些气体可能是原先冰封在海底的甲烷因为地震产生裂缝而释放出来，他也说无法确知这种易燃性的温室气体会继续冒上来多久。

Another possibility is vulcanism: Although there is no evidence of currently active Martian volcanoes, ancient methane trapped in ice "cages" called clathrates might now be released.

另一种可能性是vulcanism ：虽然目前没有证据表明火星上的火山活动，古甲烷被困在冰"笼子"称为clathrates现在可能被释放。
