Increasing speeds above Mach 1.3 results in only small changes in shock wave strength.

速度升高到1.3马赫（速度单位，1马赫=音速=340.29m/s——译者注）以后，不会再对冲击波强度造成太大的影响。

Moreover, the reason that Mach 4 oblique shock wave is asymmetric is conjectured.

另外，推测了马赫数4拟似冲击波非对称的原因。

The biggest lift drag ratio 3.36 considering viscous effects is obtained at Mach 6 when a proper base conical shock wave angle is chosen.

在设计点附近选取合适的半基准圆锥激波角并考虑粘性影响时，可得到乘波体最大升阻比为3.36；

These waves travel at the speed of sound, but when a jet travels at Mach 1 and above these waves merge into one single shock wave as they cannot get out of the way of each other quickly enough.
