Based on this model, for the Weibull distribution, utilizing the pivotal quantity and Fiducialdistribution, the confidence interval of the spare parts number M is constructed;
特别，针对储存寿命服从威布尔分布的系统，利用枢轴量，给出了前述备件数M的置信区间；
2
We have got the conclusion from the fiducial test, that the partial distribution is better than the lognormal distribution used commonly describing the structure of stock prices.
检验结果表明：偏态分布在描述股票指数及股票价格结构的行为特征上优于当前国际上常用的对数正态分布。

PD pulse phase distribution spectrum was compared with spectrum, and 95% fiducial intervals of statistic operators were also summed up.
