目前,一些县、市广播站已经采用石英电子钟输出的时控脉冲来对广播设备进行控制,以实现自动广播,所以也称这种石英电子钟为时控钟。在制作时控钟时为了简化设备,石英晶体谐振器一般都没有恒温装置,所以晶振的 At present, some county and city radio stations have adopted the time-controlled pulsation output by the quartz electronic clock to control the broadcasting equipment to realize automatic broadcasting. Therefore, this kind of quartz electronic clock is also called the clock control clock. Clock in the production of the clock in order to simplify the equipment, the quartz crystal resonator is generally no thermostat, so the crystal
