This article has analysed a change phenomenon of principal and subordinate JK trigger from the Angle of logic feedback and logic function of combining synchronous RS trigger.
从逻辑反馈的角度并结合同步rs触发器的逻辑功能分析了主从JK触发器一次变化现象。
The wide-angle sky screen can be used for measuring the terminal velocity of the projectile, and providing synchronous signal for other trajectory measurement apparatus as the trigger device of the .
该装置可以用来测试弹丸末速，作为较大靶面的触发装置，为其他弹道测试仪器提供同步信号。
