摘要
本文在郑伟涛等提出的贵金属位能函数理论基础上,从体系的自由能出发,并结合Midha状态方程,对贵金属Cu、Ag、Au多晶体的结合能、体膨胀系数进行了理论研究和计算,理论计算得到的结果与实验相当符合,其误差均在9％以内。
On the basis of Zheng’s potential function for noble metals, the present study has calculated the binding energy of Cu, Ag and Au. Following Midha’s state eduation, the formulus of thermal expansion for noble metals are presented. The application has been made to f.c.c. metals Cu, Ag and Au in the temper-ature range form 300°K to 1000°K, and a satisfactory agreement of the calcul-ated results with the experimental ones has been observed. The difference between them is never more than 9%.
