摘　　要：采用多种现代电化学研究方法和计算机数学模拟手段，研究了Ｎｉ３Ｓ２阳极在氯化物溶液中的电化学溶解。结果表明，Ｎｉ３Ｓ２阳极溶解是一种不可逆的电极过程，其反应速度受反应粒子的放电步骤和产物的固相扩散步骤混合控制，而与反应粒子的液相扩散步骤无关，在理论分析和实验的基础上，导出了电极反应的特征方程。The anodic dissolution of Ni3S2 in chloride solution was studied using some modern electrochemical research methods and by computer simulation. It was showed that the anodic dissolution of Ni3S2 is an irreversible electrode process, its reaction rate is controlled by both the electron transfer of electroactive species and the dissolution of products in solid phases; the rate is independent of the dissolution of products in the solution. Based on theoretical analysis and experiments, the authors have derived the characteristic equation of the electrode process.
