摘要 研制了一种用于评估炸药热毁伤效应的单色高温计。由单色高温计与热电偶测温对比实验可知,在单色测温中爆炸产物可近似看作黑体处理,其误差率为6.2%。运用该单色高温计对TNT爆炸产物温度进行实验测量,所得的热毁伤效应曲线较完整地反映了爆炸产物扩散过程中温度随时间的变化情况,其峰值温度为3167.15 K。 A single-wavelength pyrometer used for evaluating the effects of thermal damage was developed, which offered a new method to describe the temperature changes of explosive products during the course of the explosion. The temperature of oxyacetylene flame was simultaneously measured by the pyrometer and a thermoeouple. And the measurement error of the single-wavelength pyrometer is only 6.2%. The results indicate that the emissivity has little effect on temperature measurement of the oxyacetylene flame by the pyrometer. The pyrometer was aslo used to measure explosive products temperature of TNT. The curve of thermal damage of TNT was obtained, which shows the temperature changes of the explosive products of TNT,and the peak temperature of the curve is 3167.15 K.
