按晶面力常数的高级近似估算表面能

本文在文献[1]的基础上,计算了高级晶面力常数对表面能的影响,将其结果绘成了表面能和级数之间的关系曲线,选取了较高级、变化较平稳的几级平均值作为表面能的计算值。其结果和文献[1]的比较,普遍有所增大且明显地和实验更吻合。

Estimation of Surface Energies Based on the High Scale Approximation of Interplanar Force Constants

On the basis of reference paper [1], surface energies are estimated considering the high scale interplanar force constants with the results given in the form of surface energy-scale relation curves. Average values of some higher scales are selected for calculation. Most of the surface energies obtained are greater than those in paper [1] and more agreeable with the experiments.
