马赫

The production and transmission process of Mach cone observed in many experiments has been captured in this numerical simulation. The relation between thrust, impulse coupling coefficient and one pulse laser energy, pulse width were gained, which agreed well with the experimental results by Germany Space Center.

数值仿真中明显捕捉到有关实验中观察到的马赫杆的产生与移动过程；得出了推力和冲量耦合系数随脉冲能量、脉宽的变化关系，计算结果与德国空间中心实验吻合得较好，为脉冲激光器的选择和脉冲参数优化提供了参考依据。

By using Flash software produced a number of fluid flow in the animation, including the viscous flow in vivo experiments indicate friction, rotation speed Dengjiao containers of liquids in relative balance, the system and control of, weak disturbance in the transmission space - Mach cone, the disturbance wave Dissemination process, bypassing the wings of the two-dimensional flows, ease converter and blast crisis and stagnation flow indicate parameters and critical parameters such as the concept that a number of animation, produced by sports meeting between the animation, shape meeting between animation, masking animation and time Axis to achieve those effects the flow of fluid animation, and by adding these buttons used to control the flow of fluid animation, and so will the speed of the fluid flow in a clear show up.

The profiles of density,velocity,temperature,pressure and Mach number can be obtained by the computation.

通过计算可以得出密度、速度、温度、压力和马赫数的分布。

When compared with experimental data, the CFD predictions for Mach number data agreed to within 2 percent.

当与实验数据的计算流体力学预测马赫数数据同意在百分之二。

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。

In this case the valve outlet mach number is 0.4andthe valve noise level is approximately 85 dBA.

在这种情况下，阀门的出口马赫数为0.4，阀门的声压级约85分贝。

Thus there is a counteracting effect of increasing Mach number.

所示。因此增加的马赫数有一种抵消作用。

It can be seen, Mach number should be as large as possible, or make as small as possible.

从这里可以看出，平衡阀马赫数应尽可能大，或者使尽可能小。

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。
