| 摘 要： | 对电容器的“储能”进行了分析。填充非线性介质的电容器充电后 ,电介质具有极化能 ,这种极化能不能完全释放出来。此时W =Q22C并不表示电容器储存的能量 ,电容器的储能要比这个值小。

| Abstract: | In this paper, the storing energy of a capacitor is analysed. When a capacitor with non-linear dielectric in it is charged, the dielectric has polarization energy. If the capcitor discharges, this polarization energy can not fully be released. In this situation, W=Q 22C does not show the storing energy of the capcaitor. Actually, the storing energy is less than the value. |
