摘　　要：针对工业上起爆网路的早爆问题,设计并研制了一种可控单向传爆的新型爆炸二极管,通过一系列理论计算以及对称结构正反起爆实验,研究了该爆炸二极管的正向稳定传爆及反向可靠隔爆机理和限制因素。结果表明:该爆炸二极管可实现正向稳定传爆,反向可靠隔爆,二者对应的限制因素分别为激发药药量和延期体长度。理论分析得到的激发药的极限药量和延期体的临界尺寸与实验结果较为吻合。In the present work,to address the premature explosion for the detonating network,we designed a new type of irreversible detonation explosive diode and studied the mechanism and limiting factors about the explosive diode in transmitting the positive detonation and stopping the backward detonation,using the calculation and experiments of the symmetrical charge structure. The results show that the new type of explosive diode can achieve this aim and that the maximum amount of the firing charge and the crucial length of the delay elements from the theoretical calculation are fairly consistent with those from the experiments.
