| 摘 要： | 研究了一种新型高威力起爆药叠氮肼镍(nickel hydrazine azide,NHA)的半导体桥(semiconductor bridge,SCB)点火性能,确定了其最佳的点火参数为压药压力60MPa,电容47μF,药剂粒度49μm。研究其电压-时间曲线和电压-点火能量曲线发现:在高电压下,半导体桥产生等离子体将药剂点燃,低电压下,半导体桥产生的焦耳热可以在炸药中形成热点,将药剂点燃。

| Abstract: | A new powerful primary explosive nickel hydrazine azide(NHA) was used as charge for semiconductor bridge(SCB). The optimal conditions for the ignition were obtained: pressure 60 MPa; capacitance 47 μF; particle size of the primary explosive 49 μm. U-t curves and U-E curves show that NHA is ignited by the plasma generated by SCB at high voltage,and NHA is ignited by hot spot generated by SCB Joule-heat at lower voltage. |
