| 1. | Vertical air motions are not measured by this system .
垂直气流的运动不用这种系统来测量。 |
| 2. | An air straightener should be placed down stream from propeller to counteract circular air motion in the tube .
一种气体直线流动器应该使气流从推进器的反作用中使气体的活动在管内循环。 |
| 3. | The emission control system incorporates both inlet port ， induced air motion and compression ， induced turbulence for fast and complete combustion
可译为：发射（或推进）控制系统混合来自进气口的空气，引起空气运动和压缩，并引发空气湍流以加速并完全燃烧。 |
| 4. | With increasing restrictions on engine emissions , the need for reduced fuel consumption and low vibration , air motion and chemical reaction in the cylinder of diesel engine play an important role
内燃机缸内的气流运动和燃烧过程对发动机的整机性能有着重大的影响，是降低燃油消耗、减少排放和燃烧噪音的决定性因素。 |
| 5. | At the same time we may observe the distribution and dispersion of flame in cylinder resulting from the air motion . this may be the most direct method to open out the internal relationship among the flow , ignition and combustion . 4
目前三维螺旋进气道的数值研究绝大部分是在自然吸气状态下，即在相同的进气压力下，研究不同气门升程时的流动状态，从中找出内在的因果关系。 |
| 6. | Three models are employed to analyze the aerodynamic characteristics of a wing above sea - wave . those are ( 1 ) curve surface effect ( c . e . ) , ( 2 ) wavy air motion effect ( w . e . ) and the coupled effect a . e
研究了曲壁面效应，波动效应以及壁面和波动综合效应三种影响模式对二维和三维机翼在风浪中飞行时的气动力性能的影响规律，指出了二维和三维机翼气动力特性的共性和区别。 |
| 7. | " direct method " can give accordingly exact results , but is very time consuming ; " step by step method " needs little cpu time and can give high quality results to first part which is quite simple and easy to resolve , but fail to predict the air motion of whole room space
计算结果表明，直接模拟法相对来说最准确，但是耗费资源，局部计算能清楚显示某一区域内的流场特性，但是由于界面上的简化，引致对整个空间流场的计算误差较大。 |
| 8. | The best approach to an estimate of heat loss by this mechanism may be to calculate the heat loss by conduction and to adjust the effective wall thickness used in the conduction calculation to take in to account the fact that air motion will strip away the heated layer surrounding the skin and increase the transfer of heat to the air
最好的办法估计的热损失，由这个机制可以计算热损失由传导，并调整有效壁厚在传导计算采取在交代事实，即空气运动将剥夺加热层周边皮肤和增加转移的热量向空中。 |
