1.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.
瓦状滤波器(10)的端部被斜向切端面分别形成斜面,从而瓦状滤波器(10)的直截面呈大致梯形。
2.The male palpus is simplified, having only a single central tegular process, probably the conductor.
