可靠性分析，weibull分布极大似然参数估计和曲线拟合-reliability analysis，weibull distribution

工程上，估计某一机械等的寿命分布情况，并基于韦伯儿分布对寿命进行预测，包括对其可靠性的分析，失效函数等(In engineering, the life distribution of a certain machine is estimated, and the life is predicted based on Weber distribution, including its reliability analysis, failure function, etc)
