剪切—轴向谐振
一种类似于剪切谐振的谐振，但在变幅杆的前、后表面之间还存在一个轴向波节。在这种情况下，前表面上某给定位置的瞬时轴向运动将与后表面上对应位置的运动方向相反。被剪切波节分隔开的变幅杆相邻区段，其运动方向也相反。
这种谐振见于块形变幅杆。
另见轴向谐振。
Shear-axial resonance
A resonance that is similar to a shear resonance but for which there is also an axial node between the front and back of the horn. Under this condition, the instantaneous axial motion at a given location on the face will be opposite to the motion at the corresponding location on the back surface. Adjacent sections of the horn that are separated by shear nodes will also have opposite motion.
This resonance is found in block horns.
