摘要
本文用数值方法求二维硬盘系统吉布斯函数的极小值在位形空间中的位置,给出了该模型的状态方程和相图,发现只存在6原子固态和液态,纠正了以前人们在该模型上的一些错误结论。
With numerical method we obtained the location of minimum value of Gibbs function in configuration space for two dimensional hard disk system, and the equation of state and phase diagram of the model, we found that only the 6-atom solid phase and liquid phase can be exist in the model. The wrong method and conclusion of previcus work have been corrected.
