In order to minimize the boundary layer effects, the nozzles were made as short as possible . 为了减少附面层效应，喷咀做得尽可能地短些。
Contouring nozzles to reduce particle lag losses does not appear to be appealing . 为了减少颗粒滞后损失而成型的喷管是没有多大发展前途的。
In conclusion we note the following general items concerning flow in supersonic nozzles . 最后，我们归纳几个关于超音速喷管流动的一般原则。
Its discovery engendered the "sudden freezing" approximation for relaxing nozzle flows . 这一事实的发现导致了松驰喷管流动“突然冻结”的近似概念。
Each tube is in front of the collector nozzle only long enough to discharge the processed air . 每一个管子在集气管前停留的时间，只要足以放出处理过的空气就可以了。
The emphasis on the minimum nozzle length was carried to the limit with the design of nozzle with sharpedged throats . 强调最小喷管长度转向采用锐边喉管道的喷管设计的极限值。
The motor case is a steel cylinder closed tight at one end. the other end is the open throat and nozzle . 发动机壳体为一个其一端为密封的钢铸圆柱缸体，另一端则为敞口的喉道及喷管。
As the velocity in the nozzle throat is sonic, the effect must be transmitted upstream through the boundary layer . 当喷管喉部达到音速时，这种影响一定是通过附面层向上传播而引起的。
The design of the rocket nozzle also has much to do with the behavior of the exhaust and the resulting velocity of the vehicle itself . 火箭喷管的设计与排气的性能及飞行器本身的有效速度也有很大关系。
The liquor is pumped through a large nozzle and the velocity head is utilized to draw the gases to be absorbed into the liquid . 液体用泵送经一只大的喷头，利用速度变化产生的压差将待吸收气体带到液体中。
