摘　　要：通过对传统阿累尼乌斯法的理论分析,得出其局限性,并推导出修正公式。修正式与实验数据进行相关性检验,得出的相关系数为0.939 3,置信概率>95%。用实测性能外推法、传统阿累尼乌斯法和修正阿累尼乌斯法分别计算常温自然贮存条件下的固体推进剂寿命,对结果进行比较,确认了修正方法在固体推进剂的储存寿命预估上具有更高的精确度。Anatomizing the doctrine of and then reason out the modified formula. traditional Arrhenius model method can get its insufficiency, Through correlation check of an actual example, correlation coefficient of the modified formula and confidence probability can be obtained, and the correlation coeffi- cient is 0. 939 3, confidence probability larger than 95%. Compare the actual measurement performances of propellant in natural storage at normal temperature with the results of the traditional Arrhenius model method, the modified Arrhenius model method, and the modified Arrhenius model method respectively, showing that the modified method is more accurate for predicting the storage performance of propellant.
