摘要
本文在实验测定的基础上,以Cu为例,计算了原子在作非简谐振动情况下,晶体的热力学函数,研究了晶体表面能与表面张力随温度变化的关系以及非简谐振动对它们的影响。结果与经验公式基本一致。
Based on the measured coefficients of thermal expansion of Cu, the thermodynamic functions of crystal are calculated with static-tical physics in the nonharmonic vibration of atoms, the temperature-dependent relation of surface energy and of surface tension are found out, and the effects of nonharmonic vibration on them are discussed. The results obtained are basically in consistence with the empirical formula.
