| 摘 要： | 以最大熵原理为依据,首先通过对雷暴过程中闪电总量与闪电频次的关系分析,得到一分布函数。然后进一步讨论相对闪电量与相对历时时间之间的函数关系,建立闪电时程方程。最后选取江苏省闪电定位仪监测记录中2007—2009年20次雷暴日资料,进行分析计算,论证了最大熵原理在闪电时程中应用的可行性。

| Abstract: | Through analyzing relationship between the total lightning number and lightning frequency in the process of thunderstorm based on the maximum entropy principle, a distribution function was found in this paper firstly, then lightning schedule equation was established by further discussing the function relationship between the relative lightning quantity and the relative duration time. Finally, by selecting 20 cases from thunderstorm days data of Lightning Detection System from 2007 to 2009 in Jiangsu province, this paper analyzed and proved the applicability of the maximum entropy principle in the lightning schedule equation and whether it basically consistent with the conclusion. |
