摘要
用皮尔逊Ⅲ型曲线作极值分布计算通常均需借助于查表(Ф值表或K_ρ值表)来实现。本文通过选用适当曲线分段拟合离均系数Ф的方法替代查表,收到了理想的效果,从而实现了皮尔逊Ⅲ型曲线分布计算的完全程序化。文中给出了用于IBM-PC-AT计算机(相当于286机)上的BASIC语言程序及有关操作使用说明。
Usually φ table or Kp(Kp=Cvφ+1)table has to be referred in calculating the extremum distribution using Pearson Type Ⅲ curve. In this paper a method is proposed to replace φ table by choosing adaptable curve to fit the departure coefficient from mean (φ) ,and the Basic language program which can be used in IBM PC-AT and the program's operational guide are offered. The calculation result turned out ideal and thus completely programed computing for P-Ⅲ distribution has been realized.
