超声术语表
"词语是我们悬挂思想的挂钩。"(作者不详)
以下定义专门针对超声谐振器的设计。由于易于理解是第一要务,某些定义可能有所局限,或可能不完全严格。
为便于使用,某些术语可能列出两次,一次作为独立词条,一次作为类别列表的一部分。例如,"指数形变幅杆"既列于 -E- 之下,也列于"变幅杆"类别之下。

Glossary of ultrasonic terms
"Words are the pegs on which we hang our ideas." (unknown author)
These definitions are specifically directed toward the design of ultrasonic resonators. Because ease of understanding is paramount, some definitions may be limited or may not be completely rigorous.
For ease of use, some terms may be listed twice, once as an individual term and again as part of a category list. For example, "Exponential horn" is listed under -E- and also under the "Horn" category.
Unless otherwise noted, the following are assumed for all topics —
- All resonances are axial.
- All resonators are half-wave.
- All materials are isotropic and homogeneous.
