摘　　要：从最大熵原理出发,探讨了闪电频次与闪电强度之间的关系,得出一分布函数,并针对该函数进行了分析讨论,发现在一个完整的雷暴过程中,闪电频次与闪电强度之间大致遵从负指数关系。为验证该结论的适用性,采用江苏省闪电定位系统获得的闪电资料对其进行效果检验,发现理论结果与实际基本一致。Starting from the maximum entropy principle,the relationship between the lightning frequency and lightning intensity was discussed and a distribution function was obtained.The function was analyzed and discussed,then it was found that the relationship between the lightning frequency and lightning intensity approximately obeyed to negative index correlation during a complete thunderstorm process.In order to validate the applicability of this conclusion,the lightning data from lightning location system of Jiangsu Province were used to test its effect and the it was found that the theoretical results were essentially consistent with the fact.
