摘　　要：基于我国频率计算发展历程及频率适线软件的发展现状,以Matlab为开发环境,通过存储完整ΦP值表、修改Matlab内部函数、添加Matlab系统绘图菜单,研发了一款适合皮尔逊Ⅲ型(P-Ⅲ)分布的频率曲线绘制软件,并应用于实例中。结果表明,该软件能方便、快速地生成概率格纸,并绘制频率曲线,计算结果完全满足工程水文科研和生产设计上的使用需要。Through a brief review of development history of frequency calculation in China,as well as the present development situation of the frequency curve fitting software in recent years,a new frequency drawing software which can be used to analyzed the Pearson type Ⅲ distribution is developed by storing the full table of ΦP,modifying the internal function and adding the drawing menu of Matlab.One example is carried out and the results show that probability lined paper and frequency curve can be generated conveniently and quickly with the software,the results of which can meet the demand of hydrological research of engineering and the production design fully.
