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。
Numerical results show that contribution of high order terms are very important at lower Mach number or high angles of attack.
数值结果表明高阶项的贡献在较低马赫数或大迎角情况下是很重要的。
