摘　　要：在控制氧逸度和酸度的条件下测定了300℃时钯(Pd)和铂(Pt)氯络合物溶解度。将溶解度资料作图,求得它们的氯络合物种类分别为PdCl_4^(2-)和PtCl_3^-,计算了相应反应式的平衡常数及推导了平衡常数与温度从属关系表达式。讨论了实验结果的地质意义。The solubility of platinum and palladium at 300℃ was determined at controlled oxygen fugacity and acidity. The species of PdCl42- and PtCl3- was obtained by means of plotting the data of solubility. The equilibrium constant of the corresponding reaction was calculated and the equation of temperature dependence of the equilibrium constant was derived. Finally the paper discusses the geological application of experimental results.
