与hydrogen sulfide相关的网络例句 [注：此内容来源于网络，仅供参考]

Sulfide layer was made on the surface of high speed steel (W6Mo5Cr4V2) by means of low temperature ion sulfurization. The tribological properties of the sulfide layer under dry sliding were investigated on an MM 200 friction and wear test rig. An atomic force microscope and a scanning electron microscope equipped with an energy dispersive spectrometer attachment were adopted to analyze the morphologies and compositions of the original and worn surfaces of the sulfide layer. The phase structure of the sulfide layer was determined by X ray diffraction.

采用低温离子渗硫工艺在 W6 Mo5 Cr4 V2高速钢表面制备了硫化物固体润滑层，在 MM- 2 0 0型摩擦磨损试验机上对渗硫层的摩擦学性能进行了干摩擦试验研究，用原子力显微镜及扫描电子显微镜和 X射线光电子能谱分析渗层表面、截面、磨面的形貌及成分，用 X射线衍射仪分析了渗硫层相结构。

It was found that low hydrogen purity and high moisture content of the hydrogen used for deoxidation was the main cause. Countermeasures such as exhausting 90% of the waste gas from the deoxidation process to hydrogen recompression system to reduce the water content in deoxidation zone, and using hydrogen from PSA unit to replace recycle hydrogen to increase the hydrogen purity, were adopted.

参考UOP公司及其它重整装置的经验，对重整催化剂还原工艺进行了改进，将90％的还原废气排入增压氢系统，可有效降低还原区的水含量；用PSA氢替代循环氢，可进一步提高还原区氢纯度，从而提高还原反应速度，改善再生催化剂的性能，使重整反应的芳烃产率有所提高。

The catalytic transformation pathway can change to decrease the yield of hydrogen and yield methyl-contained sulfides such as methyl mercaptan, dimethyl sulfide and dimethyl disulfide, but overlarge concentration of methanol would holdback the transformation of isobutyl mercaptan. The transformation of isobutyl mercaptan was favorable if the volume ratio of methanol and benzene was 0.2.The addition of methanol assume certain effect on the catalytic cracking of di-n-butyl sulfide in solvent benzene but without changing the cracking reaction mechanism of di-n-butyl sulfide.

甲醇也可以使异丁硫醇的催化转化路径发生改变降低硫化氢的产率，生成甲硫醇、甲硫醚及二甲基二硫化物等含甲基硫化物，但甲醇的浓度过高会抑制异丁硫醇的转化，在反应体系中当甲醇的体积占到溶剂苯体积的20%时对异丁硫醇的转化较为有利；甲醇的添加对丁硫醚在溶剂苯中的催化裂化有一定影响，但没有改变丁硫醚的裂解反应历程。
