摘　　要：选用某种有机薄膜电容器在A(寒温)、B(亚湿热)、C(亚湿热)、D(热带海洋)等四地的库房开展了为期168个月的库房贮存试验,跟踪测试了电容量、损耗角正切值和绝缘电阻等性能参数。应用灰色预测理论中的GM(1,1)模型,对该种电容器的贮存寿命进行了预测,结果表明在A地的寿命最长,为44 a;在D地的寿命最短,为32 a。Storage test of a kind of organic film capacitor was carried out in warehouse at 4 places, A（cold climate）, B （subtropical climate）, C（subtropical climate） and D（tropical matritime climate） for a period of 168 months. Their capacitance, tan loss angle and insulation resistance were tested. Its storage life was predicted by GM （1, 1） model. The result showed that the storage life of the capacitors in A is the longest and the storage lifetime in D is the shortest; the storage life in A is 44 years; the storage life in D is 32 years.
