Mach 2

A code is developed to predict the Mach number compressible fluid flow with pressure-correction algorithm . 2 .

开发了适用于低马赫数流动的可压缩压力修正算法程序.

The steak spends a minute and a half over Mach 2, and the outer surface will likely be singed, but the heat is too quickly replaced by the icy stratospheric blast for it to actually be cooked.

牛排超过2马赫速度的时间会有1分半钟，牛排的外表面很有可能会烧焦，但热量很快就会被冰冷的平流层狂风消散掉，因而内部并不会被烤熟。

Ramjets work Best at speeds of Mach 2 ( twice the speed of sound ) and higher.

冲压式喷射发动机在马赫数为2 ( 音速的两倍 ) 或更高时工作得最好.
