摘　　要：为了准确测定高能炸药的爆轰反应温度,深入研究了高能炸药的爆轰辐射特性,采用瞬态辐射光纤高温计测量了液体炸药硝基甲烷的爆轰辐射光谱。以黑体辐射普朗克公式为基础,运用线性最小二乘法进行拟合,获得硝基甲烷炸药的实测爆轰温度为(3 552±17)K。同时,用VLW爆轰程序计算获得液体炸药硝基甲烷的理论爆轰温度为3 681 K,计算值与实测值和文献值比较接近。In order to measure accurately the detonation temperature and study on the detonation character- istic of high explosive, the detonation spectrums of nitromethane （NM） explosive were measured by instan- taneous radiant optical fiber pyrometer. Based on the Plank Law of black radiation, the detonation temper- ature of NM explosive was （3 552 ±17 ） K calculated by means of the least square method. At one time, the theoretical detonation temperature of NM explosive was 3 681 K calculated by means of the VLW code. The calculated value is close to experimental value and literature value.
