摘要
将一个矿床的产出抽象化为一个随机信号的发生,由此导出一递推微分方程组,解之得普阿松分布。证明矿床的产出过程是一个普阿松过程,进而用Γ—分布表述了其参数λ,引出了负二项分布,给出了一个完整的推导过程。
First ,the occurrence of ore deposits is extracted as a random signal generation to deduce a set of recurrent differential equations. The equations are solved to belong to Poisson-distribution. Thus it is proved that the occurrence of ore deposits is a Poisson-process. Then its X parameter is expressed by means of r-distribution,negative quadratic-distribution is deduced and a complete process of mathematical deduction is given.
