硫化物

Iron sulphide s were synthesized mainly by way of gas-solid reaction ofmetallic iron or iron-nickel alloys with the mixture of H,S and H,.

铁硫化物的合成，通常是通过固-气反应来实现，本文利用电弧放电的方法。

More importantly, ferrimagnetic iron sulphide is found in Unit A2 but absent in Unit A1, suggesting the control of marine environmental conditions on the magnetic mineral diagenesis.

铁磁性硫化物存在于A2段，但在A1段缺失，表明了海洋环境条件对磁性矿物成岩过程的控制。

Ni, Cu and PGE are very important in the study of origin and evolution of mantle derived magmas and the formation of the related magmatic sulfide deposits, because their geochemical natures are different from other trace elements.

Ni、Cu和PGE具有不同于其他微量元素的特殊的地球化学性质，这些特殊的性质使得它们在幔源岩浆起源和演化以及岩浆硫化物矿床的成因研究中具有不可替代的作用。

The maters in the surface of the strip were mainly elemental sulfur and silver.

燃料中的其它硫化物，燃烧后会生成二氧化硫，在有水的情况下，也会造成对金属的腐蚀。

The results show that the TSR reaction occurred at 425℃~525℃ with MgO, C, H2S, CO2, and a series of organic sulfur compounds such as mercaptans, sulfoethers, and thiophenes as the main products.

结果表明，硫酸盐热化学还原反应在425℃~525℃可以进行，主要生成氧化镁、炭、硫化氢、二氧化碳以及硫醇、硫醚和噻吩类等有机硫化物。

Aromatic Mercaptans and Sulfides.

芳香硫 醇及硫化物

Light straight run gasoline, lower-boiling range distillates and other non-hydrotreated fuels ("sour stocks") contain sulfur compounds such as mercaptans, that must be removed ("extraction/sweetening") to avoid problems with odor and corrosion, or prior to catalytic reforming and catalytic alkylation processes.

轻质直馏汽油、低沸点蒸馏油和其它未经加氢处理过的燃油含有硫醇类硫化物，须采取措施将其去除以免引起异嗅或腐蚀问题，或者须在催化重整和催化烷基化反应工序之前将其脱除以避免毒化催化剂。

The'black bottom Layer'of ore bodies is in fact a series of schist mylonites which are rich in graphites and sulphides. It can produce a very stable natural electric field and form an oxidation- reduction geoelectric cell in practical geological environment.

通过综合测试研究，指出金山地区矿体的&黑色底板&实际上是一套富含石墨、硫化物的千糜岩，在客观地质环境中可以产生比较稳定的自然电场，形成氧化还原地电池。

Sulfides inclusions of mantle-derived xenoliths from different districts have different gold content.

4地幔岩包体金含量高的地区，地幔岩包体中硫化物包裹体金含量也高。
