With the increase in the Numbers of vehicles, the density of traffic flow is also increased which results that vehicles move with non-uniformvelocity on road such as accelerating and braking.
The relationship between the radiation impedance and the acoustic radiated power of the radiator with non-uniform vibrating velocity on the surface is formulated.
推导了表面振速分布不均匀的辐射器的辐射阻抗与辐射器辐射声功率之间的关系。

Most of the natural river flows are non-uniform, but the start and the starting velocity drag force formula for formulas are based on uniform flow up.
