Note that it does not have the same direction as the velocity vector . 要注意它的方向与速度矢量的方向不同。
Conversely, in many experiments it is possible to measure all the velocity vectors . 另一方面,在许多实验中,所有的速度矢量都可以测定。

The acoustic radiation resistance matrix is combined with the velocity vector on a vibration surface to predict the total sound power radiated from the structure 摘要利用声辐射阻力矩阵和振动面上的速度矢量预报了结构声辐射的总功率。
