【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。更多还原

【Abstract】 In order to measure accurately the detonation temperature and study on the detonation characteristic of high explosive,the detonation spectrums of nitromethane( NM) explosive were measured by instantaneous radiant optical fiber pyrometer. Based on the Plank Law of black radiation,the detonation temperature 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.更多还原
