high-mach speed的意思|示意

Hypersonic aircraft can attack the goal nearly one thousand kilometers far during the time under 10 minutes relying on high speed (cruise at 6-10 Mach).

高超音速飞行器具有凭借其高速度(巡航马赫数6—10)，在不超过10分钟的时间内就能够打击近千公里远的目标。

The results show that the transition more likely happen under the situations with high azimuthal wave number and speed, and at a relatively low mach number and high Reynolds number.

结果表明转捩总是最先出现在来流马赫数不太大，或来流雷诺数较高并且具有较大的周向速度或周向波数的情况下。
