针对某装备系统机电产品长期自然贮存环境下可靠性无法准确评估的难题，提出了一种基于极小χ2估计和拟合优度检验的贮存可靠性评估方法，并对试验数据进行了分析、计算和处理。该方法通过拟合产品的失效分布来确定其分布函数参数，并根据确定的分布函数来预测产品的贮存可靠寿命。与现有的评估方法相比，采用该方法确定的分布函数更能反映产品的可靠性变化规律，对机电产品的贮存寿命预测结果更加合理，在工程研究领域具有很好的实用价值。

An estimating method based on minimum χ2 estimation and goodness fit of test is utilized to evaluate the storage environmental and life of the Electromechanical Products in Equipment System for test date analysis,calculation and processing. Distribution function parameter estimation and reliable storage life prediction are made by using the method. Compared with currently ways,the failure distribution function determined by the method can reflect the reliability of the product more truly. The following result of reliable storage life prediction is reasonable,and this method is promising for engineering application.
