应用一个负的触发器脉冲在一个定时周期内来同时复位和触发，这样使电容器C放电并且重新初始化一个循环，从复位脉冲的正边开始启动。
Applying a negative-going trigger pulse simultaneously to RESET and TRIG during the timing interval discharges C and reinitiates the cycle, commencing on the positive edge of the reset pulse.
当输入转换和主控门触发器同时为逻辑真时，主控门打开一定时间，这个时间由时基分配器决定。
When both the input conditioning and main-gate flip-flop are logically true, the main gate opens for a period of time that is determined by the timer base divider.
