A thin surface layer always exists near the surface of laser heating melt pool due to the fluid flow driven by the surface tensiongradient.
在激光材料加热中，由于存在着表面张力驱动的流动，熔池表面附近熔体的速度梯度很大。

The quantitatively experimental result showed that the reason that induces the Marangoni convection is the local large surface tensiongradient along the interface of the gas and liquid.
定量分析表明乙醇和水系统解吸过程中，引发界面湍动的原因是局部较大的表面张力梯度。
