摘要
推导了对数正态分布两个环境因子，分别对它们进行了点估计和区间估计，并给出了利用环境因子进行两种环境条件下参数转换的具体形式，且以实例予以说明．
Two environmental factors of log-normal distribution are deduced,and their point value and confidence intervals are estimated.For different conditions,formalisms are presented to transform the parameter under two environmental situations and an example is given.
