在典型的R LC振荡放电电路中，引入5 5 5时基电路和水银继电器作为控制电路，设计了阻尼正弦瞬变信号发生器。
In typical R-L-C resonance circuit, the 555-time-circuit and mercury relay are used as control unit. A damped sinusoid source is designed. It has been proved that the source satisfies our request.
水银填充和水银湿簧继电器是例外情况。
Mercury filled and mercury wetted relays are exceptions to this general rule.
水银湿簧开关与干簧继电器的构造方式相同，仅仅是在玻璃管内部增加了少量了的水银。
Mercury wetted reed switches are constructed in the same way as dry reed switches with the addition of a small amount of mercury inside the glass tube.
