摘要： 本文提出,在用蒙特卡罗方法模拟平衡态容器中运动粒子的器壁行为时,可以采用假想弹性壁方法。本文讨论了该方法的依、节省机时、效果及在准平衡态问题中采用该方法时可能引入的额外误差,最后以一个计算实例证明了假想弹性壁方法与直接模拟法结果的一致性。

Abstract: Use of imaginary elastic wall method to simulate the action of moving particle's on the wall of vessel at balance state was suggested. The physical bases, the efficiency of saving CPU time of the method were discussed. The extra error caused by using imaginary elastic walls in quasi-balance states was estimated also. In the last part of this article an example by using the method was placed out.
