风洞

It should be noted that a balance is not always required in a wind tunnel.

应该指出，天平对风洞来说并非是绝对必须的。

First, the quality characteristic of the wind tunnel is measured.

首先对风洞品质特性进行了测定。

Measurement of forces was performed in a wind tunnel.

提出了在风洞及水洞中进行的不同截面形状的细长机身的实验结果。

Basically the traditional measure and control system of wind tunnel runs in the Windows Operation System.

传统的风洞测控系统基本上在Windows 环境下运行。

It flexes in the wind tunnel just as if it was a real airplane flying in the air.

它在风洞中变形，就像真实飞机在空中飞行时变形一样。

And at least one group has built a physical model based on fossils and put it in a wind tunnel.

同时至少有一个研究团队根据化石建立了一个物理模型，并用其进行了风洞试验。

Wind tunnel experiments show that a ''.

风洞实验表明，鹅蛋大的''。

They all did fine in the wind tunnel.

他们在风洞测试里表现不错

That second image is very similar to the wind tunnel model I'm thinking of.

第二副图（就是北京航展上的照片，我刚才略过了）很像我说的风洞模型。

Along with WIND TUNNEL TEST and MATHEMATICAL ANALYSIS, there have been three major means for aerodynamic research and design.

它和风洞实验、理论分析已经成为现代飞行器气动力设计的三种主要手段。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
