As anti-wear agents, the s -hexyl ZDDP is found to be more effective than the n -hexyl ZDDP, and the n -hexyl ZDDP is superior to the phenyl ZDDP.

反应生成由多磷酸盐和铁硫化物组成的反应膜，该膜具有较好的抗磨作用，仲烷基ZDDP比伯烷基ZDDP的抗磨性好，而伯烷基ZDDP的抗磨性优于芳香基ZDDP的。

The brown clouds in the middle are a mixture of ammonia and hydrogen sulfide.

中间的褐色云是氢和硫化物的混合体。

According to the differences in chemical and structural characters of WO42- and MoS42- the actions of them to separator molecular such as bonding, hydrophile/hydrophobia and geometry are discussed by using mineral flotation as reference.

以相似元素钨和钼的分离为例，根据WO42-和MoS42-的结构特征，从价键因素、亲水-疏水因素、几何因素等方面分析了它们与吸附剂的作用，成功选择了有色金属硫化物作为选择性吸附剂，实现钨和钼的高效分离，并进一步探讨了吸附剂的改性优化和其它类似元素的深度分离问题。

The results indicated that when the B.subalis was applied in stimulant aquaculture wastewater,the removing rate of nitrite nitrogen and nitrate nitrogen reached above 99% after four days,pH value obviously decreased,but dissolved oxygen content and S2-content was changed indistinctively.

结果表明，枯草芽孢杆菌可迅速有效的降低水体中的硝酸盐、亚硝酸盐含量，4 d去除率均达99%以上；可有效降低水体的pH值；对水体中溶氧和硫化物含量的影响较小。

Corrosion products on plain 12CrMoV and mild steel specimens were the same, mainly ferric sulfate and ferrous sulfate, with no sulfide of metals either on surface or at scale/substrate interrace.

在20~#钢、12CrMoV试样上的腐蚀产物主要是硫酸铁和硫酸亚铁，在其表面和内界面都没有看到金属的硫化物。

Natural diamonds often exist in the Kimberlite pipes of the mantle, where often contain the inorganic elements--- sulfur. So the inclusions of natural diamonds are always carbonate minerals and sulfide. Undoubtedly, the study of the additive sulfur action in the course of synthesizing diamond will further our understanding the reason of natural germ formation.

天然金刚石多产生于地壳中的金伯利岩和钾镁煌斑岩，该岩层中含有非金属元素硫，天然金刚石中的包裹体通常为硅酸盐矿物和硫化物[41]，因此研究添加剂硫在合成金刚石中的影响是认识天然金刚石成因的重要方面。

In the intermediate chamber, besides the liquation of silicate melt from sulphide phases, gravitational differentiation based on density of rocks also took place.

镁铁超镁铁质岩浆在中间岩浆房除发生硫化物与硅酸盐的〓离之外，还可按相对密度大小发生使岩浆分层的重力分异作用。

I didn't watch TV last night, because it .
