中文摘要：

为了研究火炸药在外界点火作用下的点火感度和评价火炸药的使用安全性,设计了一套基于高压放电的瞬态点火装置和基于示波器DPO4054的点火能量测试系统。通过燃料空气炸药的点火试验,测得50%的点火能量为2.443J。为精确测试样品的点火能量提供了一种新途径。

英文摘要：

To study the ignition sensitivity of explosive under the outside effect and evaluate the security of use. A transient ignition devices based on high voltagean discharge and an ignition energy test system based oscillography DPO5054 are designed. Through igniting the fuel air explosive （FAE）, the ignition energy of 2. 443J of fifty percent is obtained. This offered a new method for exactly testing the ignition energy of the sample.
