vertical section

This illustration shows a vertical section through the locust.

本图所示为蝗剖面。

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)端部被斜向除以使端面分别形成斜面，从而波器(10)垂直截面呈大致梯形。
