| 摘 要： | 一维平面对称爆轰波的推进具有周期性.其冲击波前沿(该处未发生化学反应)对于波后是亚音速的,由于后续扰动不断追上而衰减.炸药微元被冲击波压缩和加热,经过延迟期,由快速放热而形成冲击波,称为"化学冲击波",追上原冲击波前沿,使之增强到初始强度,至此完成一个周期.

| Abstract: | Periodicity advance model of 1-D slab symmetry detonation wave is investigated.The advance of an 1-D slab symmetry detonation wave shows a periodicity in structure.The velocity of the wave ahead(in which no reaction takes place) is subsonic for the wave after it,and it is attenuation by rarefaction wave catching up.Detonation wave heats up the explosive and triggers the "chemical shock waves",it catches up the shock wave ahead and increases to its initial parameters.Thus,a whole period has been accomplished. |
