1. A discharging method of high pressure exhaust gas by measn of a chock wave confinement in a duct been developed. The duct, which is conneted to an exhaust gas pipe, has inlet and exit orifices so that the flow is foubly chokes at these sections.2. For analytical purposes, the flow in the duct is assumed to be a frictional and adiabatic flow with a normal shock wave. The calculated results show that the total pressure reduction increases with a decreasing opening area of the inlet orifice, and the shock wave confinement in the duct can be achieved by cesreasing the opening area of the exit orifice.3. An apparatus for confinement of a shock wave, whick is generated by an expansion of hihg pressure exhaust ga, has benn constructred and tested over a wide range of pressure tations across the duct. The location of the shock wave in the duct agrees well with the calculated results. On the ogher hand, the trotal pressure loss actoss the duct is much larger than the calculated values, becouse the schok becomes a presudo-shock.4. The theoretical and experimantal results mentioned above indicate the validity of the present discharging method, and the present method is quite useful for controlling and discharaging og high pressure exhause ga. The data for shock wave confinement have been obrained.

1。开发了通过测量导管中的chock波限制的高压废气的排放方法。该管道连接到排气管，具有入口和退出孔口，因此在这些切片中流动堵塞。2。出于分析目的，假定管道中的流动是具有正常冲击波的摩擦和绝热流。计算出的结果表明，随着入口孔口的开口面积的减少，总压力降低增加，并且可以通过筛选出口孔口的开口区域来实现管道中的冲击波限制。3。 HIHG压力排气GA的膨胀产生了用于限制冲击波的设备，Benn在整个管道的大量压力范围内进行了构造和测试。冲击波在管道中的位置与计算结果非常吻合。在Ogher的手上，Trotal压力损失Actoss远高于计算值，因为Schok成为Presudo Shock.4。上面提到的理论和实验结果表明当前放电方法的有效性，目前的方法对于控制和放电的高压劝诫GA非常有用。冲击波限制的数据已被尊重。
