摘　　要：本文首先从理论上论述了膜电容器的储能密度与寿命之间的关系 ,对国际电容器制造水平和趋势进行了分析 ,提出采用干式金属化膜电容器作为储能元件。最后 ,根据电磁发射兵器整体寿命配合原则 ,提出高储能密度脉冲电容器的合理寿命指标。The relationship between the density and lifetime of film capacitors, the present day level of capacitor production and the trend of density development in the world were analysed. Dry metallized capacitors are proposed to be used as the energy storage element. According to the request on the lifetime of an electromagnetic launcher, a resonable lifetime target of high energy density capacitors was put forward.
