摘要
电中性的金属片被电容器所带电荷吸入其中而发生振动.这里讨论的问题:有或无阻尼时金属片的振动规律;电场力使金属片加速或减速运动过程中的功能转换;金属片振动过程中保持电容器的电量或电压不变,储能的变化;金属片的每一振动周期电源供给电容器的能量;电容器的电压、电量等参数的周期性变化.
The electric neutral sheet metal inhaled into the capacitor vibrates by the attraction of capacitor' s electric charges. The problems discussed here are follows: vibratory rule of sheet metal with or without damping; function convertion in movement that electric field force makes speed up or down of sheet metal; electric quantity or voltage of the capacitor remain unchanged energy storage keep changed in sheet metal vibratory process; the power source to supply capacitor' s energy in each sheet metal vibrating cycle ; the periodical change of capacitor voltage, electric quantity and other parameters.
