2、。学习 protel软件,绘出电路原 理图。下文是对两种不同火工品的点火脉冲信号进行时间测量。试看在脉冲点火电 路中点火电流和火工品电阻对脉冲的宽度有何影响。 第 2 页 共 41 页 ABSTRACT EED is to provide ignition, detonation, or power source components or devices sensitive to small explosions of energy. Although the name is very strange, but widespread application. This paper begin
3、s with the concept of EED, classification and characteristics and so introduced into the explosive expansion of the specific design and application. Explosive in terms of an extremely important parameter as well the role of explosive time. The subject of the ignition pulse for the explosive action t
4、ime test circuit and pulse circuit design, Pulse ignition for explosive design type test, The type of explosive on the ignition pulse width and pulse current size of the production requirements of high precision. First clear pulse generator circuit theory, research methods and the output pulse of the output pulse of the appropriate adjustment method. Second, we must understand the role of time-tested principles. Design output of two current pulses from the pulse circuit and time to ignition i
