爆炸发生在结构内部时，结构受到双重荷载作用：瞬时的冲击波荷载和长时间的准静态气体压力。

When explosion took place inside structures, the structure bore dual load: the transient shock wave and long duration quasi-static gas pressure.

这样的缓慢压缩能使这种气体经历一系列的状态，但各状态都很接近于平衡状态，所以叫作准静态过程，或“近似稳定”过程。

Such a slow compression carries the gas through a series of states.each of which is very nearly an equilibrium state and it is called a quasi-static or a“nearly static”process.
