摘 要:本文根据统计分析原理,使用电子计算机验证多孔材料表面孔径服从瑞利(Rayleigh)分布律: PR(x)={x/μ2e-x2/2μ2- x≥0 0 x<0
Abstract: Based on the principle of the statistical analysis, the microcomputer was used to testify that porous materials’ plane pores--size is in agreement with Rayleigh distribu- tions, i. e. x/μ2 e x2/2μ2 x≥0 PR(x)= 0 x<0
