Supply has in creased at an even greater pace as sulfur recovered from oil and gas refining, and from non-ferrous metal smelting has displaced voluntary production of sulfur from Frasch mining and pyrites production.

世界硫供应增长的速度更快，石油和天然气加工过程中回收的硫磺产量和有色金属冶炼回收的硫酸产量迅速增长，逐渐代替了矿产硫磺和硫铁矿的生产。

在西南地区晚二叠世煤中首次发现了热液成因的硫锰矿和硫砷锑矿、碱性火山灰成因的胶态锐钛矿和陆源碎屑成因的斜绿泥石。

Alite and C4A3S are the main minerals of Portland cement and Alite sulphoaluminate cement.

阿利特和无水硫铝酸钙矿物分别是硅酸盐水泥和硫铝酸盐水泥的主导矿物。

Alite and C4A3 are main minerals of Portland cement and Alite sulphoaluminate cement.

摘 要：阿利特和无水硫铝酸钙矿物分别是硅酸盐水泥和硫铝酸盐水泥的主导矿物。

The influences of the sulfide source and Na_2S_2O_3 solution concentration on the preparation of nanometer mercuric sulfide/amidoxime composite fiber were investigated,and the antibacterial properties of different fibers to staphylococcus aureus and bacillus subtilis were studied.

探讨了硫源和硫代硫酸钠溶液浓度对制备纳米硫化汞/偕胺肟复合纤维的影响，并研究了纤维对金黄色葡萄球菌和枯草芽孢杆菌的抗菌性能。运用红外光谱仪及扫描电镜对样品进行了表征。

The suitable method to dissolve Antheraea pernyi silk fibroin fibers and the character of regenerated silk fibroin solution were investigated in this paper.

研究了柞蚕丝素纤维的溶解途径和再生丝素溶液的性质，指出硝酸钙和硫氰酸锂的浓溶液是柞蚕丝素纤维的良溶剂，再生柞蚕丝素的分子量为20kDa～102.4kDa，硝酸钙对丝素大分子的破坏程度比硫氰酸锂大。

Theoretical studies on various geometrical structures of Hypophosphorous acid were carried out using DFT theoretical methods, at the B3LYP/6-311 ++ G(superscript **) level. Intramolecular proton transfer isomerization has also been studied using the intrinsic reaction coordinate.

采用量子化学密度泛函B3LYP方法，在6-311++G基组水平上全优化得到了硫代次磷酸的硫酮式和硫醇式两种构型异构体以及相应的对映异构体，同时对分子内质子转移异构化反应微观机理进行了理论分析。

Pure sulfur, a tasteless, odourless, brittle yellow solid, occurs in several crystalline and amorphous allotropes, including brimstone and flowers of sulfur.

纯硫是无味无嗅的淡黄色脆性固体，呈晶体状或非晶体状，如硫黄石和硫华。

Pure sulfur, a tasteless, odourless, brittle yellow solid, occurs in several crystalline and amorphous allotropes, including brimstone and flower s of sulfur.

纯硫是无味无嗅的淡黄色脆性固体，呈晶体状或非晶体状，如硫黄石和硫华。

Balanced fertilization was introduced by the government in 1985, including the use of N, P, K and S. Indonesian farmers sometimes apply high rate of urea up to 500 kg urea/ha to rice which promote lodging and disease incidence. Potassium chloride and ammonium sulphate are relatively new materials for farmers and the adoption is 60% for KCl and 61 % for ammonium sulphate.

平衡施肥这项措施是1985年政府提出的，包括氮，磷，钾和硫之间的平衡，印尼农民在水稻上氮肥用量过高，有时达500公斤尿素/公顷，这样使倒伏和病虫害加重，氯化钾和硫酸铵对农民来说是二种新型肥料，只有60%的农民施用氯化钾，61%的农民施用硫铵。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.
