以氮化铅(LA)、斯蒂芬酸铅(LTNR)、叠氮肼镍(NHA)、硝酸肼镍(NHN)、四氮烯(Tz)和苦味酸铅(LP)为对象,研究了起爆药SCB等离子体点火能量和药剂特性之间的关系.结果表明,等离子体点火能量和药剂表观活化能之间没有直接的相关性;当药剂反应转化率为5%时,LTNR、NHA、Tz和LP的温度与其相应的等离子体点火能量之间的相关系数为0.81,但综合考虑6种起爆药时,其相关性则显著下降;经过修正,LA、LTNR、NHA、NHN、Tz和LP的临界温度T_c和等离子体点火能量的相关系数为0.82,表明等离子体点火能量和起爆药性能(特别是临界温度)之间有一定关系.
以氮化鉛(LA)、斯蒂芬痠鉛(LTNR)、疊氮肼鎳(NHA)、硝痠肼鎳(NHN)、四氮烯(Tz)和苦味痠鉛(LP)為對象,研究瞭起爆藥SCB等離子體點火能量和藥劑特性之間的關繫.結果錶明,等離子體點火能量和藥劑錶觀活化能之間沒有直接的相關性;噹藥劑反應轉化率為5%時,LTNR、NHA、Tz和LP的溫度與其相應的等離子體點火能量之間的相關繫數為0.81,但綜閤攷慮6種起爆藥時,其相關性則顯著下降;經過脩正,LA、LTNR、NHA、NHN、Tz和LP的臨界溫度T_c和等離子體點火能量的相關繫數為0.82,錶明等離子體點火能量和起爆藥性能(特彆是臨界溫度)之間有一定關繫.

The relation between semiconductor bridge(SCB) plasma ignition energy and some chemical characteristics of primary explosives including lead azide(LA), lead styphnate(LTNR), nickel hydrazine azide(NHA), nickel hydrazine nitrate(NHN), tetrazene (Tz) and lead picrate (LP) are investigated. The result indicates that there is no direct relation between plasma ignition energy and activation energy of explosives. It shows that correlation coefficient is 81% between plasma energy and the temperature of LTNR,NHA,Tz and LP when the reaction conversion degree is 5%. However, the correlation is deteriorated as all the six explosives are considered. As for the relation between plasma energy and critical temperature of those six compounds, the correlation is better when the heat reaction is modified and the coefficient is 0.82,illuminating that there exist connection among plasma ignition energy and explosive characteristics, especial critical temperature.
