查询词典 air gas

A pitot tube is a pressure measurement instrument used to measure fluid flow velocity. The pitot tube was invented by the French engineer Henri Pitot in the early 1700s and was modified to its modern form in the mid 1800s by French scientist Henry Darcy. It is widely used to determine the airspeed of an aircraft and to measure air and gas velocities in industrial applications.

速度感应器，俗称空速管，最早就是法国工程师 Henri Pitot 先生发明，并在一个世纪后由另一位法国工程师 Henry Darcy 先生改进而成为现代形式的重要器件，广泛用于探测气体或液体的速度变化，并把数据传到给控制中心。

Because the air was perfectly still, poison gas wouldn't float away on the wind.

因为空气是完美地静止，毒气不会随着风刮走。

The heat pipe air preheater s are widely used in the recovery of waste heat of gas.

热管式空气预热器广泛应用于烟气的余热回收。

Explosion can occur if the producer gas is mixed with sufficient amount of air to form explosive mixture.

This new type heat pipe was applied in a puddling process. The waste flue gas from the hot blast stove was used as the hot source to heat the cold mixture of compressed air and coal powder. The observed practical performance of the heat pipe showed a good agreement with the design expectation, which verified feasibility of using the separated type heat pipe for the heat transfer of the solid powder.

这种新型的分离式热管换热器应用于一个固相粉末换热系统——利用高炉热风炉的废烟气加热高炉喷煤用的空气和煤粉的混合物，实际运行工况与设计结果具有良好的一致性，可见利用套管结构的分离式热管作为以固相粉末为换热介质时的传热元件是完全可行的。
