中文摘要：

为了研究炸药热反应规律，采用多点测温的烤燃实验装置，对PBXCl0炸药进行了不同加热速率下的烤燃实验，测量了从炸药边沿到炸药中心不同位置的温度变化。建立了炸药烤燃实验计算模型，对炸药热反应过程进行了数值模拟计算。根据实验测量的炸药温度与时间曲线，标定了PBXCl0炸药指前因子和活化能，分析了不同加热速率下炸药热反应特征。提出了按照炸药内部热量传递方向，把炸药烤燃分为慢速，中速和快速烤燃3种形式，给出了区分3种烤燃形式的判断方法。分别计算了PBXCIO，JB9014和JOB90033种炸药在不同温度下的热爆炸过程。结果表明：PBXCl0炸药热感度在JB9014和JOB9003炸药之间。

英文摘要：

To investigate the thermal reaction law of PBXC10 explosive, the multi-point temperature measuring cook-off tests were carried out at different heating rates. The explosive temperatures were measured from its edge to its center. An explosive cook-off test model was set up. The numerical simulations were conducted to calculate the explosive thermal reaction. According to measured T-t curves of explosives, the activation energy and frequency factor of PBXC10 explosive were obtained. The thermal reaction characteristics of explosive at various heating rates were analyzed. Based on the direction of heat transfer, the cook-off tests were described in three forms of slow cook-off test, medium cook-off test and fast cook-off test. The thermal explosion processes of PBXC10, JB9014 and JOB9003 explosives were calculated at different temperatures. The results show that the heat sensitivity of PBXC10 explosive is between those of JB9014 and JOB9003.
