Then a few kinds of compounds with good corrosion inhibition effect have been got in hydrofluoric acid solution.

选取这几类化合物中的硫脲、硫氰酸钠、丙炔醇和溴代十六烷基砒啶分别作为研究对象。

The insecticide included the mixed liquid of isofenphos-methyl and phoxim,inartificial nematocida and fenamiphos of different concentrations.

药剂处理使用了甲基异硫磷加辛硫磷混合液、天然杀线剂和克线磷，各药剂分别使用不同浓度进行处理。

A mathematical model among the investment,cost and income and internal rate of return was established.

在分析高含硫气田开发经济评价特点的基础上，运用技术经济的基本原理，在估算开发投资、成本、收入的基础上，建立了高含硫气田经济评价模型，通过实例计算出不同投资、成本、价格下的内部收益率，并运用SPSS软件对数据进行一元和多元回归处理，得到投资、成本、价格与内部收益率之间的数学模型。

The results showed that the deposition rate increased at first , then went down with increasing concentration of thiourea or potassium iodate. The deposition rate was more significantly affected by thiourea than that by potassium iodate.

结果表明，沉积速率随硫脲、碘酸钾浓度的增大先升高后降低，碘酸钾对镀速的影响不如硫脲显著。

Pointing at fluctuant sulfur content and burning character of metallurgical quicklime sample, determining sulfur in metallurgical quicklime by combustion iodometry is improved.

针对冶金石灰试样中硫含量波动大及燃烧的特征，改进了燃烧碘量法测定冶金石灰中的硫。

Organic sulfur can promote the deposition of metal ion.

有机硫对重金属离子有极强的沉淀作用，Cd和UV-B复合作用时协同促进了有机硫分泌。

In recent years, because the sulfur corroded accidents and so on refinery which, storage and transport equipment revelation occurred to occur frequently, created the huge economic loss to the enterprise, the analysis accident cause factor discovered that the iron pyrites spontaneous combustion was the primary cause which the initiation exploded.

近年来，由于硫腐蚀而发生的炼油、储运设备泄露等事故频繁发生，给企业造成巨大的经济损失，分析事故原因发现，硫铁化物的自燃是引发爆炸的主要原因。

Isinglass and other animal gelatin and its ramification.

硅、砷、二氧化硅、氯化物、溴化物及碘化物、稀土金属、钇、钪及其混合物、其他氯化稀土、碳酸稀土；柠檬酸、氨基酸酯及盐、氨基酸、有机硫化合物、双巯丙氨酸、甲硫氨酸、仅含有氧杂原子的杂环化合物，抗菌素，青霉素和有其结构的青霉素衍生物，链霉素及其衍生物以及它们的盐，四环素衍生物及其盐；鞋靴、家俱等的光洁剂、擦洗膏、明胶及其衍生物；鱼胶；其他动物明胶及其衍生物。

The massive sulphide, lead-zinc, iron, copper deposits of the former and the porphyry copper-molybdenum deposits of the latter are the main ore types in the region.3. The conclusions drawn through the research on the Re-Os isotopic geochronology of the Chilu Mo deposit are as follows:(1) the model age of the Chilu Mo ore deposit is 105.6Ma, closely to the 87Sr/86S isochrone age of the porphyric granite, adamellite. So they are closely correlated in the genesis, and both are the production of magmatic evolution of the late Yanshan.

Cu、Mo、Pb、Zn、Au为区内优势矿种。3、对赤路钼矿床的Re—Os同位素年代学研究得出如下结论：(1)赤路钼矿的矿化模式年龄为105.6Ma，与似斑状花岗岩、二长花岗岩等的87Sr/86Sr等时线年龄115±4Ma较接近，表明二者在成因上密切相关，同属燕山晚期岩浆演化的产物；(2)赤路钼矿床具有辉钼矿中Re、Os含量偏低，低87Sr/86Sr初始值和硫同位素组成接近陨石硫等特点，表明其为成矿物质来源于地壳深部，且为斑岩型钼矿床。
