摘要
本文由Gruneisen第二定则出发,采用普适能量函数作为原子间相互作用势能函数,计算立方晶体金属元素和几种NaCl 型结构的碱卤晶体的线膨胀系数。计算值与实验值符合得很好。
Starting from the second law of Gruneisen and making use of universal potential energy function as interaction potential function between atoms, we calculated thermal expansion coefficients of the cubic crystal metallic elements and alkali halide crystals at room temperature. The calculated value is in a very suitable agreement with the experimental value.
