And comparing with radiation heating, atom diffusionvelocity at interface quickened.
与辐射加热相比，接触面处原子扩散速率加快。
2
The mixing layer flow was numerically simulated by the discrete vortex method, in which the diffusionvelocity method was adopted to model the viscosity.
对混合层流动进行了数值模拟。采用了离散涡方法。计算中采用扩散速度法处理粘性作用项。
3
The diffusionvelocity of the interlayer is direct proportion to welding temperature, the composition of base metal is the key of the welding temperature choice.
