摘要
提出了一种利用改进的极大似然估计法对基于威布尔分布的环保型电子节能灯寿命数据进行分析的方法.该方法利用加速寿命实验获取环保型电子节能灯使用寿命的数据,利用统计学的方法和威布尔分布模型,实现高应力下的实验时间的等效折算.采用改进的极大似然估计,有益于对环保型电子节能灯的寿命数据进行分析.
A new method for the analysis of life data of environment-protecting and energy-saved lights based on Weibull-distributing by improved maximal likelihood estimate put forward.This method uses the life data of environment-protecting and energy-saving lights gained by accelerated life testing.It realizes equivalent-conversion of experimental time under the condition of high stress by using the method of statistics and the model of Weibull-distributing.The life data of environment-protecting and energy-saving lights by using improved maximal likelihood estimate is availability.
