常流的 meaning in English

ever flowing

Velocity distribution of unsteady flow of non - newtonian fluid ineccentric annuli with the inner cylinder reciprocating axially
流体在内管做轴向往复运动的偏心环空中非定常流的速度分布
The next large block of lectures covers quasi - one - dimensional flow , followed by a discussion of disturbances and unsteady flows
接下的一大块内容介绍了准一维流动，其后是关于扰动流与非定常流的讨论。
In addition , unsteady flow simulation needs to gain flow movement along time . as a result , the computing task of the numerical simulation is very great
另外，在非定常流的模拟中，需要获得流动随时间的变化过程，这使得计算工作量变得十分巨大。
The exhaust system and muffler are simplified as a set of 1 - d pipes with non - isentropic flow and with variable sections . the partial differential equations of non - stationary flow are transferred into the stationary differential equations by means of the characteristic lines . these equations are solved by finite difference method
在排气管系的计算中将排气管简化为一组一维非等熵变截面管，并通过“特征线法”将描述其运动的非定常流的偏微分方程转化为常微分方程，再用差分数值方法依靠计算机求解。
