摘要
实验发现了表面回波对衍射光的干涉现象，波矢量随位置变化及表面振动模式与表面相有关．考虑波矢量变化特性后，给出了表面波色散关系的修正公式及回波干涉规律．观察了表面波的光栅衍射效应，同时测量了表面张力。
The interference between the light diffracted incidence surface wave and reflection surface wave is observed.The wave vector varies with propogation distance and the variation of surface phase causes the variation of viberation mode of liquid surface.The formulation of surface wave chromatic dispersion is reconstructed and theoritical results of interference by reflection surface wave are derived.The surface tension of water and its variation with temperature are detected.
