已调谐
- 谐振器的期望谐振落在指定频带内的状态。
示例：对于指定的 19950 Hz 至 20050 Hz 频带（即标称 20 kHz），当轴向谐振器的轴向谐振落在该频带内时，即认为其已调谐。 - 电源经过调整，使其工作特性与叠堆相匹配的状态。
实现上述任一状态的过程称为调谐。
Tuned
- A condition in which a desired resonator's resonance falls within a specified frequency band.
Example: for a specified frequency band between 19950 Hz and 20050 Hz (i.e., nominally 20 kHz), an axial resonator is tuned when its axial resonance falls within this frequency band. - A condition in which the power supply has been adjusted so that its operating characteristics match those of the stack.
The process by which either of these conditions is achieved is called tuning.
