谐振的

This allows the tank circuit to be as sharp as it can be. There is some sacrifice of volume, but it is well worth it. The 7-45 pf trimmer is set to around 20-30 pf.

它使得谐振曲线尽可能的尖锐，尽管在音量上有所损失，但这是值得的。7-45 pf 半可变电容调节在大约20-30 pf 处。

Also it is found that when the reflectivities of two antireflection and high-reflection coatings increase, and the stable oscillation of the master wave is established in the external cavity, the threshold current is the lowest, but the efficiency of the electro-optical conversion and the power of the output light reduce sharply.

并且发现当两端面的反射率增加，同时激射波长在外腔长度中形成稳定谐振时，激光器的阈值电流达到最小值，但相应的电光转换效率和出光功率会急剧地减小。

It can be concluded that in a certain velocity interval, resonance of gas intake can improve the dynamic performance of single-cylinder engine.

因此，在一定的转速范围内，合理利用进气谐振可以有效提高发动机在该工况下的动力性能。

To raise the sound intensity of the modulated aerodynamic acoustic source in low frequency region, the resonances in two resonance pipes, a straight pipe and a bi-curved horn were tested by forcing the airflow of sound wave to pass through them.

为提高调制气动声源在低频处的发声强度，将含声波的气流通过直管和双曲喇叭两种谐振管产生共振。

Compared with Figure 6, one can see, as time progresses, the time Reverberation-Chamber fluctuations reduce the average electric field value, and gradually become stable, while the rectangular cavity resonance due to its role in the convergence very slow wave, volatile .

通过与图6比较，可以看出，随着时间的推进，混波室的时间平均电场值波动减小，逐渐趋于稳定，而矩形空腔由于其谐振作用，波形收敛很慢，波动很大。
