谐振的

I used 165/46 litz instead of larger litz because regenerative radios tend to be "Q multipliers". I thought that the 660/46 wire would make the radio too sharp and perhaps unstable.

我用了165/46李兹线而没有用更多股数的原因，是因为再生电路有&倍Q&作用，我想660/46李兹线可能使得谐振曲线太过尖锐而使得电路变的不稳定。

It is found that certain transmission zeros can be created by nonadjacent frequency-dependent coupling.

In 1959 Sauerbrey developed an empirical equation to describe the mass sensitivity of gas phase mass deposition on a piezoelectric quartz crystal——Sauerbrey equation:ΔF=〓=-CΔm, where ΔF is measured frequency shift, in Hz; F〓 is the fundamental resonant frequency, in Hz;Δm is mass change, in g; A is piezoelectrically active area , in cm〓;μ〓 is shear modulus of quartz, 2. 947×10〓g· cm〓;ρ〓 is density of quartz, 2. 648g·cm〓; C is mass sensitivity constant , in 〓.

1959年，Sauerbrey最先提出了将压电晶体谐振器用作定量测量质量的装置，并从理论上导出了频率与质量变化之间的关系式——Sauerbrey方程：ΔF=〓=-。。。
