| 摘 要： | 以价电子能级结构理论对金属表面的原子能态进行分析，计算了表面原子结合能，并在此基础上得到表面超额焓的经验计算公式。将此公式推广到金属液固比表面焓、液态表面张力的计算，结果与实验值一致。

| Abstract: | A Model of the interaction between atom and crystal(IACM)was established and was applied to analysize the atom energy level on the crystal surface. Experiential equation was used to calculate the surface energy levels, the surface energy of liquid metal, the interface energy of liquid-solid, and the latent heat of phase change. The results agree with the experiments pretty well. Furthermore, the abnormal phenomena of the surface tension for some metal such as Cu, Fe,which increase with temperature,can be explained by the calculating model. |
