exit velocity

Unfortunately, the trim exit velocity head alone is not a good predictor of such animportant phenomena.

可惜, 单靠阀门内件节流出口速度头并不能很好的预测这种现象.

The effects of pressure, mass velocity, inlet subcooling, heat flux, and exit throttle on the flow instability were determined in the modeling experiment. The thresholds of the flow pattern transformation instability and that of the density wave instability were obtained.

通过模型试验确定了压力、质量流速、入口过冷度、热流密度、出口节流阻力等因素对不稳定性的影响，得出了流型转化型和密度波型不稳定性的界限。

A heavier arrow loosed by the longbow would have had a significantly reduced exit velocity.

而长弓发射重箭速度有很明显的下降.

The gas average velocity and mean temperature increase greatly at the channel entrance, and both the temperature and velocity at the channel exit decrease with the increase of Kn numbers.

在通道入口附近，气流速度和温度变化剧烈，而在出口处截面平均流速和温度随Kn的增加而降低。
