刃形变幅杆
一种成型条形变幅杆或削平圆柱形变幅杆，其输出截面为矩形但面积小于输入截面，从而为变幅杆提供增益。（在此含义下，“刃”一词并不表示任何切割能力，尽管刃形变幅杆也可以被设计为具备这种能力。）
Scotto[3]（Mecasonic）将其称为 "pelle"（铲子或锹）。
另见刃部。
Blade horn
A shaped bar horn or flatted-cylindrical horn where the output cross-section is rectangular but of smaller area than the input cross-section, thereby imparting gain to the horn. (In this connotation, "blade" does not indicate any cutting ability although a blade horn may be designed for such ability.)
Scotto[3] (Mecasonic) refers to this as "pelle" (shovel or spade).
