马赫

Shown is the Mach number in a slice through the central 40 kpc of the galaxy.

图中展示的是一个过中心的厚度为40 kpc的一个切片的马赫数。

It is found that the unity Mach number isn't right at the throat but a little bit downstream of the throat.

发现马赫数为1的位置不是出现在喉部，而是在喉部下游一点的位置上。

If the pressure drop across diffuser restricted, have to choose a lower Mach number.

如果扩散器两端压降受限制，只好选择较低的马赫数。

The analytical results showed that Reynolds number and Mach number have a rather obvious effect on airfoil aerodynamic performances.

分析结果表明：雷诺数和马赫数对翼型气动性能有较大的影响。

The method for the unstart Mach number is described.

本文还提出了一种确定不起动马赫数的方法。

In this paper,we mainly explore how to break through the low Mach number anduniform mesh limitations as following

本文在突破低马赫数，均匀网格限制方面作了一些探索研究，具体为

The center left plot shows the pressure distribution and beneath that is plotted the Mach number distribution.

中心左侧的阴谋显示，压力分布和下方是策划马赫数分布。

Experience has shown that, if the beam pipe stream Mach number remained at 0.3 below, it will not cause trouble.

经验表明，如果管路中流束的马赫数保持在0.3以下时，就不会引起麻烦。

The simulation of results indicated that with Mach number increased and the total pressure recovery coefficient decreased.

模拟结果表明：随着飞行马赫数的增加，由前缘点产生的激波逐渐靠近弹体，进气道内部总压恢复系数降低，在进气道出口处压力比较高，出口流场基本均匀。

In an ideal nozzle, the exit flow is completely parallel to the nozzle axis and possesses uniform pressure and Mach number.

在一个理想的喷嘴，出口流是完全平行的喷嘴轴，并拥有统一的压力和马赫数。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
