This paper discusses the influence on the oxidation number of each sulfur atom when the charge possesses different position in thiosulfate,polythionate and so on.

本文讨论了代、连多等中所带电荷在不同位置时对氧化数所影响,提出了定代、连多等中每个原子氧化数方法。

Using sodium hydrosulphide or sodium thiosulfate as materials,the production cost of TGA is low.While,a high content of TGA can be obtained with thiourea as reactant.

本文对巯基乙合成工艺进行了比较研究,认为氢化钠法和代钠法成本低,适宜于选矿用巯基乙,而脲法可得到较高浓度巯基乙。
