极值I型分布恒加应力试验的统计分析

Statistical Analysis of Constant Stress Accelerated Life Testing for the Occasion of Extreme Value I Distribution

对极值 I型分布场合 ,排除形状参数与加速应力无关的限制 ,进行恒加应力寿命试验统计分析 ,给出正常应力水平下寿命分布的参数及变异系数估计 .

A statistical analysis is made on the constant stress accelerated life testing. It is made for the occasion of extreme value I distribution where the restriction that shape parameter remains unchanged at different stress levels. The estimates of parameter and variation coefficient of life distribution are given under normal stress level.
