摘要
研究了两参数BS疲劳寿命分布BS(α,β)密度函数f (t)和失效率函数λ(t)顶峰点的位置以及在中位数β左右侧的图像特征,并给出了判断失效率函数图像特征的更为一般的结论 .
The image features of density function f(t) and failure rate function λ(t) at the peak and around the median βare studied for two-parameter BS fatigue life distribution.Meanwhile,a general conclusion for identifying image feature of failure rate function is proposed.
