Through the study of characteristic of macroelement , microelement , rare - earth element , oxyhydrogen isotope , sulfur isotope , lead isotope , fluid inclusion etc , a conclusion can be drawn that metallogenic substance comes from the upper mantle with mixing of some substance from the upper crust latter . it is likely to have the same source with the surrounding rock 通過對礦床的常量元素、微量元素、稀土元素、流體包裹體特征、氫氧同位素、硫同位素、鉛同位素等特征的研究,認為成礦物質主要來源于上地幔,與周圍巖石存在著同源的可能性,后期有一定的上地殼物質混入,成礦作用有三期,分別與區內的花崗巖、二長花崗巖脈、云煌巖脈有關。

To determine the vitriolic solute quality mark in sewage does following tests : take 10 grams this sewage , chase to the middle of sewage drop join solute quality mark to change sodium solution for the oxyhydrogen of 4 % , if plan institute is shown , the ph change of the quality of solution of natrium of oxidation of place drop hydrogenation and solution concerns 為測定污水中硫酸的溶質質量分數做如下實驗:取10克該污水,向污水中逐滴加入溶質質量分數為4 %的氫氧化鈉溶液,所滴加氫氧化鈉溶液的質量與溶液的ph變化關系如圖所示。
