摘要
根据等熵条件下冲击波的关系式,计算了不同超压下,冲击波速度、压缩空气层速度、温度和密度变化值,具有一定的工程价值;指出了压缩空气层密度增长超过极限比的错误。
Based on the relational ex-pression of shock wave under isentro pic condition,the paper cal-culated the variable values of the velocity of shock wave and the velocity,temperature and density o f compressed air layer under different overpressure,which are o f certain value to the engineer-ing,and it also pointed out the mista ke of the density increase of compressed air layer beyond its limi t ratio.
