| 摘 要： | 统计分布参数的求取是可靠性研究的基础，对于只含有一个或两个参数的统计分布，已有许多方法来求取其参数，但对于具有复杂形式的分布，其多参数求取比较困难。作者提出把求解统计分布参数问题归结为求解非线性优化问题，调用现成的优化程序即可方便地求出具有复杂形式的统计分布的参数。所给出的例题表明，该方法是可行的。

| Abstract: | The calculation of parameters of the statistic distribution is the foundation for the study of reliablity.There are many metheds to be used to calc ulate the parameters of statistic distribution with one or two parameters.However,it is difficult to calculate the distribution parameters with com-plex statistic distribution.The present authors propose a method which refers a problem of calculatingstatistic parameters to a problem of non-linear optimization.By means of the ready-made ptogram ofoptimization procedure, it is convenient to calculate the parameters of statistic distribution. The exam-ples indicate that the proposed methed is feasible. |

| Keywords: | optimization parameters of statistic distribution Weibull distribution. |
