摘要
应用带有望远镜的原子发射光谱双谱线瞬态高温测量系统遥测了炸药爆炸的瞬态实时反应温度，该系统的最大时间分辨率可达0.1μs．实验得到温压炸药的爆炸反应温度-时间分布曲线，并与TNT同条件下的测试结果比较．结果表明，温压炸药爆炸时，产生2300K和2050K2个温度峰值，分别对应于温压炸药爆炸反应的第一、第二阶段，TNT爆炸后只出现一个最高温度2200K；温压炸药1900K以上高温持续时间是TNT的2～3倍．
A remote-sensing high-temperature transient measurement system of double lines of atomic emission spectroscopy with telescope was used to measure the explosion temperature of explosive. The time resolution of the measurement system can achieve 0.1℃. The explosion temperature of Thermobaric Explosive （TBE） and TNT were measured by this remote sensing method under the same conditions, and the distributing curves of temperature vs. time were obtained. The experimental result of TBE was compared with that of TNT. There are two temperature peaks of 2 300K and 2050 K corresponding with the first and second phase of explosive reaction of TBE respectively, while only one temperature peak of 2 200 K appears when TNT explodes. The duration of high temperature higher than 1 900 K of TBE is 2 - 3 times that of TNT.
