| 摘 要： | 本文用几何方法对二维系统的融化过程作了全面的研究。在仅考虑排斥势的情况下修正了Kawamura等人的理论,理论计算值与计算机模拟实验的结果接近。在计入吸引势后采用凝聚态Van der waals理论中的近似展开,所得融化曲线在三相点附近更接近正确的位置。

STATISTICAL GEOMETRIC THEORY OF MELTING |
| |
| Abstract: | The geometric approach to the melting process of a two-dimensional system is studied. For the hard disk system the theory developed by Kawamura and others is modified, so that the agreement between computer simulation experiment and theoretical calculation is much better. For the system with attractive potential the melting line is calculated by a perturbation expansion of condensed Van der Waals theory, it's locatioa near triple point in phase diagram is more realistic. |
