| 摘 要： | 根据气相爆轰波胞格结构的规则特则特性建立一种以子单元分解胞格结构的新方法，根据该子单元的性质和斜冲击波关系，求解胞格结构中的三波点对撞问题，并推导贯穿胞格时，爆轰速度的相对波动幅度仅依赖于胞格几何形状的关系，然后，采用爆炸波衰减模型，计算气相爆轰波贯穿胞格时的衰减过程，计算结果与实验符合得较好。

| Abstract: | The study of this paper deals with the variation of gaseous detonation waves through the cell. Firstly, the cellular structures were defined by subcells. With the properties of subcells and oblique shock wave relations, the solution of the collision of triple structures was presented, and the direct relation between the relative fluctuation of detonation waves and the geometrical properties of cells was also derived. Then the attenuation process of the detonation waves through the cell was calculated. The analytical results were compared with experimental results; good agreement was obtained. |
