摘要: 采用电探针及压力传感器测试技术对密度为1.597 g/cm3的固体B炸药（TNT/RDX=40/60）的燃烧转爆轰性能进行研究。实验结果表明，在较强的约束条件下（45号钢管，内径20 mm，外径64 mm，长500 mm），B炸药形成了DDT现象，诱导爆轰距离为295~310 mm。

Abstract: Deflagration-to-detonation transition (DDT) of composition B (TNT/RDX=40/60) with density 1.597 g/cm3 is experimentally explored by using the electrical pin and pressure sensor measurement techniques. Experimental results show that a DDT is obtained under the strong confinement condition (steel tube with inner diameter 20 mm and outer diameter 64 mm and length 500 mm), and that the detonation-induced distance is 295 ~310 mm.
