为了研究炸药在加热前后的燃烧转爆轰特性变化，设计了加热条件下燃烧转爆轰试验加载系统，对Φ30 mm ×400 mm的PBX-2炸药进行了试验。试验中采用热电偶测试装置壳体和炸药表面温度变化过程，采用离子探针测量了燃烧转爆轰过程的传播时间和距离，探讨了加热与未加热PBX-2炸药的燃烧转爆轰特性。结果表明，与未加热相比，加热至85℃时PBX-2炸药更难以发生燃烧转爆轰现象。

In order to study characteristics of deflagration to detonation transition( DDT) of unheated and heated explosives, the DDT test device for heated explosive was designed.And the PBX-2 explosive samples with Φ30 mm ×400 mm were made.The processes of temperature changing for device shell and explosive were measured by thermocouples.The transmitting time and distance were analyzed by ionic probe.The characteristic of DDT for unheated and heated explosives were gained.The results show that DDT is more difficult to occur for PBX-2 explosive at 85 ℃than room temperature.
