for the further supersonic range, performance losses increase slightly with increasing mach number.

在继续的超声速范围内，性能损失随外流马赫数增加只有小幅增长。

No matter the boundary layer is subsonic or supersonic, nonparallel effects are obvious at the critical Reynolds number, such that the critical Reynolds number is reduced and the frequency range of unstable disturbances is broadened at the critical Reynolds number.

无论是在亚音速还是超音速边界层中，非平行性的影响在临界雷诺数处比较明显，具体是一使得临界雷诺数变小，二使得临界雷诺数处增长扰动的频率范围变得更大。
