1) overtone ratio method
泛音比法
1.
The easier coupling of the thickness fundamental resonance with the higher overtone of low-resonant modes leads to a bad measurement accuracy of the thickness series resonance frequencies or a failure of the resonance frequency measurement,resulting in deteriorating the accuracy and the identity of the electromechanical coupling factor determined by the traditional overtone ratio method.
压电振子低频振动模式的高次泛音易与厚度振动模式的基频相耦合,导致厚度振动的基音串联谐振频率不能精确测量(或无法测量),造成传统泛音比法测定压电振子的机电耦合系数的精度和一致性变差或无法进行测定。
2) higher overtone ratio method
高次泛音比法
1.
To overcome the shortcoming of the traditional overtone ratio method,a higher overtone ratio method to determine the thick.
为了克服传统泛音比法的这一弊端,提出了测定压电振子厚度振动机电耦合系数的高次泛音比法。
3) Overtone techniques
泛音技法
4) overtone
[英]['əʊvətəʊn] [美]['ovɚ'ton]
泛音
1.
The generative mechanism of overtone in quartz-crystal multivibrator is discussed.
对石英晶体多谐振荡器泛音频率产生机理进行了理论分析,并在此基础上提出了抑制泛音频率的方法。
2.
Base band and overtone will be generated at the same time when the string of stringed instrument oscillate.
弦乐器琴弦的振动中包含基频与泛频,在一定位置上可抑制掉某些频率,便会出现演艺界定义的“泛音”效果。
5) a harmonic tone
泛音,和音
6) 3rd overtone
三次泛音
1.
Fabrication of 49U/S 3rd overtone blank;
三次泛音49U/S晶片的研制
补充资料：泛音
一般的乐音都是复音，一个复音中，除去基音（频率最低的纯音）外，所有其余的纯音叫做泛音。也叫陪音。
