流速剖面 meaning in English
fluid velocity profile
Examples
- These include the rotating disk , the towed plate , and the velocity profile methods
这些方法包括旋转圆盘牵引板以及流速剖面方法。 - Results of inspection and application show that the velocity profile simulated by hough transform is more close to the measured values than that simulated by the least square method
经过检验与应用表明，霍夫变换拟合的流速剖面比传统的最小二乘法更接近实测值。 - The first two are indirect methods in as much as they rely on measurements of overall torque or resistance and boundary layer similarity laws to obtain du + , whereas the velocity profile method provides a direct measurement of du +
首两个是间接的方法一样因为他们依靠的测量整体扭矩或阻力和边界层相似性法律以取得杜+而流速剖面法提供了一个直接测量杜+ 。 - Under different positions of a tripping wire or speeds of the side jet , the controlled experiments were made , including the receptivity of the shear layer near jet exit to acoustic excitations , the spatial development of fluctuating velocity and the profiles of mean velocity
