Precise delay pulses are generated by the digital circuit, after being magnified and sharpened through multistage isolated amplifiers and rising edge sharpening device, high-voltage steep delay pulses with precision less than μs level are obtained. This system has been used in our compact magnetic flux compression generator experiments in place of the traditional primaeord delay device.展开更多
文摘研究2A12铝弹丸超高速碰撞2A12铝靶板产生的电磁场对通信电路的干扰.实验中采用盘式磁线圈对超高速碰撞产生的电磁场进行测量,获得了碰撞速度为5.93 km/s下不同的空间位置处磁感应强度以及与上弹道方向平行的不同放置位置处通信电路的受干扰情况.实验结果表明:超高速碰撞产生的电磁场会使通信电路受到严重的干扰,电磁场对通信电路的干扰幅值达到了1 V.
