Ends of the tegular filters (10) are cut off crosswise to make the end surfaces respectively form inclined surfaces such that vertical sections of the tegular filters (10) are in a rough trapezoid.

波器(10)的端部被斜向切除以使端面分别形成斜面，从而波器(10)的垂直截面呈大致梯形。

Based on machine kinematics and cutting theories, the simulating method for the generation of three-dimensional surfaces in face turning and flycutting of SPDT is studied.

基于床运动学和切削理论对单点金刚时的件端面切削及“飞切”进行了仿真建模。

By the analysis, it has been concluded that slopy ridge has better discharge effect comparing with verical ridge.

结论-试验证明，斜墙式消力坎的倾角越大，消能率越大，同时收缩端面处的回漩流速也更大。
