在线性分层的水体中；由拖动坚条形栅格产生湍流锋面，通过阴影可视化技术考察了锋面的流态和运动行为，将锋面迹线经过图像处理，获得了锋面运动特征的有关信息：运动速度随时间的增长关系；锋面坍塌的平均无因次特征时间为NTC＝2．9；它随湍流Froude数Fri的增大而减小；锋面的特征尺度Hf与栅格运动的参数有关；当湍流演化成内波时，对锋面与内波运动间的关系进行了初步探讨和分析．
In a linear stratified water body, the turbulent front is generated by dragging a rigid grid, the fluid flow and the movement are analyzed by shading visualization techniques, and the frontal traces are processed through images to obtain the information about the frontal movement characteristics : The relationship between the movement velocity and the growth of time is as follows: the average dimensionless feature time of the frontal collapse is NTC = 2.9; it decreases with the increase of the Froude number Fri of the turbulent flow; the feature scale Hf of the frontal plane is related to the parameter of the grid movement When the turbulence evolved into an internal wave, the relationship between the frontal and internal wave motion was discussed and analyzed.
