根据非完整统计的思想,利用最大熵原理,在约束条件下,推导了非广延参数相同和不同情况下正则系统和巨正则系统的统计分布,并借助Matlab绘制概率分布曲线。结果表明,当约束条件中非广延参数相同时,其概率分布为指数形式,这与Tsallis统计分布的幂律形式显然不一样;当约束条件中非广延参数不相同时,其概率分布不能精确求解,通过仿真拟合实现了幂律化。
根據非完整統計的思想,利用最大熵原理,在約束條件下,推導瞭非廣延參數相同和不同情況下正則繫統和巨正則繫統的統計分佈,併藉助Matlab繪製概率分佈麯線。結果錶明,噹約束條件中非廣延參數相同時,其概率分佈為指數形式,這與Tsallis統計分佈的冪律形式顯然不一樣;噹約束條件中非廣延參數不相同時,其概率分佈不能精確求解,通過倣真擬閤實現瞭冪律化。

According to the view of incomplete statistics, using the maximum entropy principle, under the constraint conditions, derived the statistical distribution of canonical ensemble and grand canonical ensemble under the different nonextensive parameters, also the same nonextensive parameters. Meanwhile, the probability distribution curves are plotted using MATLAB. The final result shows,When the Non-extended parameters have the same values, Its probability distribution is exponential form, This is obviously different from the power rate form of Tsallis statistics distribution; When the Non-extended parameters have the different values, The probability distribution can not be solved accurately, the power law fitting is realized by simulation.
