1. The TAB contains a toothed wheel which is driven at a high angular velocity by the impinging airstreams. 舵片上有一个带齿的轮,这个轮受到气流的冲击而高速转动。
2. Air foil fans are designed, engineered and tested for airstreams requiring high efficiency and quiet operation. 我们公司生产的机翼型叶风机要求在高效,安静的气流操作环境下运行。
3. The impinging jet injection device improves combustion efficiency. If the fuel streams impinge with the airstreams directly at the exit of air-inlet, it makes negative effect on combustion efficiency. 燃气射流与空气流在进气道出口直接撞击不利于燃烧效率的提高。
