摘　　要：根据水波质点运动的轨迹方程及水波传播速度表达式深度认识水波的传播特点,指出高中物理教材对水波折射概念描述的不准确性,厘清水波折射的概念。从水波由深度不同的一种水域运动到另一种水域过程中水势变化引起传播速度变化的角度剖析水波折射的本质原因,同时根据惠更斯原理对水波折射予以解释。Based on the trajectory equation of water wave particle motion and the expression of water wave propagation speed, this paper deeply understands the propagation characteristics of water waves, points out the inaccuracy of the description of water wave refraction concept in high school physics textbooks, and clarifies the concept of water wave refraction. Analyzing the essential reasons for water wave refraction from the perspective of the change in propagation speed caused by the change in water potential during the movement of water waves from one water body with different depths to another, and explaining water wave refraction based on the Huygens principle.
