摘　　要：采用加强约束的方式对几种不同尺寸的PBX-2炸药进行火烧试验,用热电偶测试了样品内部不同位置的温度变化过程,通过冲击波超压测量了不同尺寸炸药样品的反应程度,分析了不同尺寸PBX-2炸药在火烧试验中的响应规律。结果表明,在相同的壳体厚度以及一定的约束强度下,PBX-2的尺寸越小反应越强烈,尺寸越大反应越弱。Fast cook-off tests for different size PBX-2 explosives were made by strengthening restriction： The temperature changing processes of different pOSitions in the sample were measured by thermocouples, and the reaction degree of different size explosives was gained by blast pressure gauges. The reaction rule for different size PBX-2 explosives was analyzed by the results of fast cook-off test. The results show that the reaction of PBX-2 explosives is more violent with smaller size and weaker with larger size under the same thickness shell and definite restricted intension.
