单元厚度
对于块形变幅杆的指定单元，指其两相邻槽壁之间、或其槽壁与变幅杆侧面之间的距离（沿变幅杆厚度方向测量）。该尺寸不应计入因耳状突起、环带等造成的厚度减薄部分。
块形变幅杆通常设计为所有单元厚度大致相等，但这并非硬性要求。
另见单元宽度。
Element thickness
For a designated element of a block horn, the distance (measured in the direction of horn thickness) between its two adjacent slot walls or between its slot wall and the side of the horn. This dimension should not include any reduced thickness due to earing, banding, etc.
Block horns are usually designed with all elements of approximately equal thickness, although this is not a requirement.
Also see element width.
