摘　　要：将一种能直接观测任意深度处的水质点运动轨迹的示踪装置引入到实验教学中,该装置操作简单方便,在实际实验教学应用中取得了良好的效果。通过受力分析证明了该装置对波浪水质点水平运动轨迹示踪的有效性,并用该装置对规则波和不规则波开展了示踪实验,将示踪粒子实测数据与经典微幅波理论进行分析对比,验证了示踪装置对波浪作用下水质点水平运动示踪的适用性。A tracing device which can directly observe the trajectory of water particles at any depth is introduced into experimental teaching,which is simple and convenient to operate and has achieved good results in the practical experimental teaching application.The effectiveness of the device on tracing the horizontal trajectories of wave water particles is verified by the force analysis,and the tracing experiment is carried out for regular and irregular waves by this device.By comparing the measured data of the traced particles with the classical theory of the micro-amplitude wave,the applicability of the tracing device for the horizontal motion of water particles under wave action is verified.
