| 摘 要： | <正> 1.引言 由于组成统计微元的单个微裂纹,既不是古典的牛顿粒子,也不是量子的微观粒子,所以它们既不遵从古典力学的哈密顿方程,又不遵从量子力学的薛定谔方程,它们的运动规律一般由实验或先验模型来给出。本文从简化的、但抓住了物理实质的模型入手,给出了两种成核率函数,应用统计方法,通过计算分析,得出了一维微裂纹统计演化行为的物理图像。

| Abstract: | Owing to tensile stress pulse results in spallation in materials, it is necessary to investigate the statistical evolution of micro-cracks. For this sake two nucleation rate functions are proposed. The details of statistical evolution of one dimensional micro-cracks are presented in this paper. |
