摘　　要：利用美国ＤｕＰｏｎｔ公司的９９００型差示扫描量热仪对３个含铁闪锌矿样品的热容进行了实验测定，并讨论了定压摩尔热容实验值与实验温度的关系。实验结果表明，在实验条件下，含铁闪锌矿的定压摩尔热容与纯闪锌矿的定压摩尔热容存在显著差异，Ｆｅ置换Ｚｎ是造成这种差异的主要原因。The heat capacities of three samples of (Zn 1- x ,Fe x )S are measured using DuPont differential scanning calorimeter(DSC),and the relationship between heat capacity and experimental temperature is discussed in this paper.The experimental results show that the heat capacity of (Zn 1- x ,Fe x )S is related to the thermodynamic property and the content of FeS.
