音速

Empirical results are needed in the transonic Mach regime.

在跨音速马赫数范围内需要经验结果.

But most of all, l wanna drive this car right through the sound barrier.

但是, 我最想做的是开这辆车突破音速.

This lets the gas escape and slows the bullet to below the speed of sound.

由此气体得以枪管里泄出,而子弹的速度也会降到音速以下.

The aim is to fly at approximately Mach 2, which is twice the speed of sound.

目标是飞行速度达到约2马赫，这是音速的两倍。

Prey to a military thrust transonic flight, feeling and F-15 Afterburner almost open.

猛禽以军用推力跨音速飞行, 感觉上和F-15开加力差不多.

It would reach hypersonic speeds -- five times the speed of sound.

也就是说,要使飞机达到特超音速—即音速的五倍.

The new airplane flies at twice the speed of sound.

这架新式飞机以两倍于音速的速度飞行.

An effective aerodynamic optimization design method of transonic airfoil is given.

提出了一种有效的跨音速翼型气动优化设计方法.

The aeroacoustic field generated by a transonic two-blade Hartzell propeller was calculated by using Kirchhoff method.

本文采用Kirchhof方法计算双桨叶Hartzel跨音速螺旋桨的远场气动噪声.

Pneumatic signals will travel only at sonic speeds.

气动信号的传输速度仅仅相当于音速.

The flight speed of new-style SST plane is 3 times sonic.

新型SST飞机的飞行速度为音速的3倍.

Light travels faster than sound. That's why some appear bright until you hear them speak.

光速快于音速. 这就是为什么你在听到他人的发言后才会意识到他们的存在.

The supersonic combustion chamber inlet is a 2 D convergent-divergent nozzle.

高超音速冲压发动机由进气道、超音速燃烧室和喷管组成.

Since light travels faster than sound, people appear bright until you hear them speak.

由于光速比音速快, 所以在我们听到人们开口之前,个个都显得很聪明.—萧伯纳.

The holes themselves have a restricting or stabilizing effect because flow may become sonic.

因为这时流动可成为音速流动,所以这些小孔本身有一种节制作用或稳定化作用.
