| 摘 要： | 基于聚合物电老化陷阱理论和自由基反应动力学，推导出聚合物在电热联合老化条件下的寿命公式，并通过对聚丙烯薄膜的电热联合老化寿命数据和聚乙烯不同温度下电树枝起始电压数据的统计分析，理论公式得到了实验验证。

| Abstract: | Based on the trap theory of electrical aging in polymers and the reaction dynamics of free radicals, the life formula of combined aging under electrical and thermal stresses in polymers in deduced in this paper. The theoretic formula are verified by the aging test of PP films and the Treeing initial test of PE. |
