在静水槽中进行了分层流体中运动物体生成的内重力波与自由面相互作用的实验研究。分层介质为水盐水以及柴油盐水两种情形。研究的重点是物体在密度突跃层附近运动时导致的自由面的特定变形，讨论了物体的位置和运动速度等因素对变形形态的影响。对密度突跃层本身的变形特征也作了描述。
An experimental study on the interaction between internal gravity waves and free surface generated by moving objects in stratified fluid was carried out in still water tank. Stratified medium is water salt water and diesel salt water two kinds of situations. The research focuses on the specific deformation of the free surface caused by the object moving in the vicinity of the sudden jump of density, and discusses the influence of the position and velocity of the object on the deformation. The deformation features of the abrupt layer itself are also described.
