摘　　要：对不同温度,不同浓度(分析常用浓度)下的HNO3与CuS反应产物的分析表明:CuS与HNO3的反应产物不局限于NO、NO2和单质S,还有NO2-和SO42-生成,是一个比较复杂的反应。从理论上对CuS在不同温度、不同浓度的HNO3中溶解反应方程式的写法进行了分析推断。The analysis of the reactant products of CuS and HNO3 （ analyse daily density ） that is in different temperatures and concentrates shows： the reactant products of CuS and HNO3 not only confine NO. NO2 and S, but also have NO2^- and SO4^2- , it is a more complicated reaction. We have analysed and conducted the reaction equation of CuS dissolves in HNO3 which is in different temperatures and concentrates theoretically.
