And comparing with radiation heating, atom diffusion velocity at interface quickened.
与辐射加热相比，接触面处原子扩散速率加快。

Based on the finite element analysis results of the dynamic properties of the structure, the acoustic radiation of the structure is analysed using the results of the surface velocity distribution.
Based on the acoustic radiation mode analysis, the transfer matrix relating the pressure at every field point to normal component of surface velocity is formed.
