短路谐振
对于压电系统，指一种机械谐振，其频率 /( f_{sc} /) 对应于压电陶瓷被短路（所有电极表面连接在一起）的状态。（见 Hirose[1]，第 213 页。）压电系统可以仅由压电陶瓷组成，也可以由压电换能器组成，或由压电换能器加所连接的谐振器组成。
短路谐振的特征是阻抗低（即导纳高），因此在给定驱动电压下能产生相对较高的振幅。
短路谐振总是伴随着一个频率稍高的开路谐振。见短路谐振与开路谐振的比较。
这种谐振状态常被称为"串联谐振"。然而，这一术语背后的含义需要理解压电陶瓷的等效电路，而"短路谐振"的概念在物理上直观易懂，因此更为可取。
历史上，这种谐振状态曾仅被称为"谐振"。不过一般应避免使用这一称谓，因为它可能与泛指的谐振一词混淆。
Short circuit resonance
For a piezoelectric system, a mechanical resonance whose frequency /( f_{sc} /) corresponds to a condition where the piezoelectric ceramics are short circuited (all electroded surfaces connected together). (See Hirose[1], p. 213.) The piezoelectric system may consist of piezoceramic(s) alone, piezoelectric transducer(s), or piezoelectric transducer(s) plus attached resonators.
Short circuit resonance is characterized by low impedance (i.e., high admittance) which yields relatively high amplitude for a given drive voltage.
A short circuit resonance is always accompanied by a somewhat higher open circuit resonance. See Comparison of short circuit resonance and open circuit resonance.
This resonance condition is often called "series resonance". However, the meaning behind this terminology requires an understanding of the piezoceramic's equivalent circuit whereas the concept of "short circuit resonance" is physically intuitive and is therefore preferred.
Historically this resonance condition has just been called "resonance". Generally, however, this terminology should be avoided since it may cause confusion with the general term resonance.
