共振變壓器
英文
resonance transformer-
The ultrasonic motor is a kind of direct driver which is uses the converse piezoelectric effect of the piezoelectricity ceramics, by using transformation and the coupling of each kind of expansion and contraction vibration pattern enlarging the material microscopic distortion by resonate effect and transforming it to macroscopic movement of the rotor or the slide by the friction coupling
超聲波馬達是一種利用壓電陶瓷的逆壓電效應，通過各種伸縮振動模式的轉換與耦合，將材料的微觀變形通過共振放大和摩擦耦合轉換成轉子或者滑塊宏觀運動的直接驅動器。2. prepare the self - adaptive damper which consists of piezoelectric ceramic and er fluids. the experiment show that the resonant peak of the self - adaptive damper minish more than 30 % compared with the damper whose electrostatic field built by piezoelectric ceramic did not charge up er fluids
結果表明，前者相對於後者，阻尼器共振峰被壓抑了60以上，從而證實了壓電陶瓷在外壓力作用下產生的靜電場可以驅動電流變液； 2Diode switches or voltage controlled varactors implement dual - band resonators such that they can offer low impedance at the second harmonic of each frequency band, while, in some cases, presenting high impedance at the fundamental frequency as an rf choke circuit
利用二極體開關或電壓控制變容器實施雙頻共振器以提供在雙頻操作中每一個頻段之二階諧波的低阻抗，同時在一些實施例里也提供主頻段的高阻抗、兼具有射頻阻塞電路作用。Since the concept of superlattice was proposed, vertical transport in superlattice has been investigated widely. the electric field domains and current self - oscillations which result from sequential resonant tunneling between different subbands of the superlattice are very significant phenomena. such kind of oscillation can be uesd to make tunable microwave oscillaors. in this thesis, low temperature transport problem, especially the formation of field domain and the condition of current self - oscillations in doped gaas / alas superlattice with weak coupling are investigated thoroughly and also by combining the macroscopic model with the microscopic one., the voltage - current characteristic and the current oscillation are simulated. the calculated result is nearly consistent with the experimental data
由超晶格中子能級之間的順序多阱共振隧穿引起的電場疇及電流自維持振蕩現象是其中的一個非常有意義的分支，該現象可用來製作電壓調諧微波振蕩器。本論文對弱耦合摻雜gaaa alas超晶格中的縱向輸運特別是針對低溫下的場疇的形成和固定偏壓下電流自維持振蕩產生的條件進行了深入的探討，並結合宏觀模型和微觀模型對超晶格在時變電壓作用下的電壓-電流特性以及固定偏壓作用下的電流特性進行了模擬計算。分享友人
