日最大降水量服从极值分布的一个例证

An Example of Extremum Distribution of Daily Mazimum Precipitation

采用经验及统计理论方法推算出新疆喀什日最大降水量服从极值分布，其分布函数ｐ（Ｒ）＝１－ｅｘｐ｛－ｅｘｐ［－１６．７８（Ｒ－１３．５８）］｝。这为“原始分布为指数分布，其最大项服从极值分布”的理论提供了又一个例证。

t is formulated that the daily maximum precipitation obeys the extremum distribution in Kashi of Xinjiang by means of empirical and statistical theory method. Its distribution function is p(R)=1-exp{-exp1678(R-1358)]}This gave an example that its maxima obeys extremum distribution when the distribution of an random variable is exponentical one.
