摘　　要：本文利用概率理论讨论了两种孔形(圆形和方形)的蚀刻核径迹的统计性质,给出一定标称孔隙率下重孔几率的解析表达式,并借蒙特卡罗方法对多重孔现象的统计特性进行了计算机模拟。并且用重离子照射PET薄膜,在显微镜下观测了不同径迹密度(P1)下单孔、双孔和多重孔出现的几率。Statistical properties of quadratic and circular tracks are investigated by analytical calculations and Monte Carlo computer simulations. Analytical expressions for tne effective porosity and the probability of forming single, double and multiple holes are given e.s a function of the nominal porosity. A computer simulations is given. The above probability is determined by observing the number and diameter of holes under an optical microscope.
