双语例句

1
The effects of flow speed increase the mean square velocity and radiated power, the effect on radiated power is more obvious than on velocity.
随着流速的增加，结构的法向均方速度和辐射声功率均增大，但流速对结构辐射声功率的影响远大于对结构速度均方值的影响；
2
The non-homogeneous metal flow during the extrusion forming process was well controlled by introducing a non-equilibrium parameter of metal flow, the mean-square deviation of velocity (SDV).
通过引进一个反映金属流速不均衡性的参数———流速均方差，有效地控制型材挤压成形时金属流动的不均匀性。
3
Using these formulas and a 1-d LDA, mean square value of 2-d turbulent velocity fluctuation and Reynolds shear stress have been measured for water flow in a square duct.
用这些公式和一台一维激光多普勒测速计，测量了方形管道中水流的二维湍流速度脉动的均方值和雷诺切应力。
