摘　　要：基于可燃气体中爆燃向爆震的转变机理 ,推测出可能强化两相爆震的几种方法 ,然后逐一进行了实验研究 ,找出了强化两相爆震的最为行之有效的方法。该项研究成功地产生了理想的 C- J爆震 ,表明本脉冲爆震发动机 (PDE)模型已能按照理想Based on the mechanism of deflagration-to-detonation in gaseous mixture, some potential methods for strengthening two-phase detonation are deduced, and then are investigated experimentally. As a result, the most effective method for enhancing two-phase detonation is obtained. It is shown that the ideal C - J detonation is successfully produced in this pulse detonation engine model and it can work properly.
