偶極諧振子和可以用積分后的光子吸收截面來表示。Using the semiclassical theory, we calculate the correction of the detuning to the absorption and dispersion, and we investigate the impact of the one - photon detuning under the exact two - photon resonance to large kerr nonlinearity and photon switching based eit

本文是在吸收前人研究成果的基礎上,理論聯系實際,針對高效、高功率密度、高壓大功率直流電源展開的研製工作。在經過大量的實際調研工作的基礎上,選擇了一種軟開關變換器(移相控制的串-並聯諧振變換器)的技術方案,並圍繞該方案展開理論研究和實際的設計工作。We study the time evolution law of the atomic response in an open - type inversionless lasing system when the probe or driving field is off - resonance, and compare the law with that obtained when the probe and driving fields are resonant. we find that the detuning has considerable effects on the time evolution law : when the probe or driving fields is off - resonance, the dispersive responses for the probe and driving fields are no longer 0 and the two - photon coherence is no longer a pure real ; the variation of the probe detuning can make the time evolution law of the population distributions and the gain ( absorbtion ) of the driving field changing obviously ; with detuning increasing, the time evolution behavior of the gain ( absorbtion ), dispersion of the probe field and the two - photon coherence will gradually diviate from the evolution law of the standard damped oscillator ; with the driving detuning increasing, the oscillating time of the dispersion of the driving field becomes longer, the amplitude and the stationary value increase
研究了探測場或驅動場失諧情況下開放的型無粒子數反轉激光系統中原子響應的時間演化規律,並與探測場和驅動場都共振時的演化規律進行了比較.我們發現失諧對時間演化規律有顯著的影響;當驅動場或探測場失諧時,原子對探測場和驅動場色散的響應不再為零,雙光子相干不再是純實量;探測場失諧的變化將使粒子布居和驅動場增益(吸收)的時間演化規律明顯改變;隨著失諧的增大,探測場增益(吸收) 、色散和雙光子相干隨時間的演化行為逐漸偏離標準阻尼振子的演化規律;驅動場色散驅動場失諧量的增加而振蕩時間變長,振幅和穩定值變大A lcc multi - resonant ( mr ) network is added to the traditional three - level converters to realize zvs. the unique arrangement of a multi - resonant network results in absorption of all major parasitic components hi the resonant circuit, such as transistor output capacitance, diode junction capacitance and transformer leakage inductance, which can eliminate parasitic oscillation in the converter
它的優點在於諧振電容吸收了開關管和續流二極體的結電容,諧振電感吸收了變壓器的漏感,使得開關管和續流二極體都能在軟開關的條件下完成導通和關斷過程,消除了電路中的寄生振蕩。The idea of passive control is to utilize additional facility within a structure to dissipate or absorb a large portion of the seismic energy, which has been applied to practical engineering extensively since its control devices - dampers are convenient and it does not need large energy supply and the structural system identification. now the main devices which have been developed in the passive control may be grouped into the following types : viscous, visco - elastic, metallic and frictional, and tuned mass damper ( tmd ) and tuned liquid damper ( tld )
被動控制通過附加阻尼裝置耗散或吸收大部分的地震動能量以達到減振的目的,由於其控制裝置簡單,不需要外界能源輸入和系統識別,容易在工程上實現並已得到廣泛的應用;目前被應用於結構被動控制的阻尼器主要有:粘滯型、粘彈型、摩擦型、調諧質量阻尼器( tmd )和調諧液體阻尼器( tld ) 。And it should be linear polarization in s direction by analyzing the relations between the reflection, absorption loss of optical thin film at oblique incidence and the polarization state, and at this time the brewster window made of very low - absorption material can be used

諧振、準諧振或多諧振技術方案,變換器的電壓電流應力較高,變頻控制增加了濾波器設計的難度;能量緩沖吸收電路或有源鉗位電路方案,由於需要增加多個額外輔助元件,增加了變換器的復雜性;全橋相移技術方案,由於主電路無需增加額外元件,只需利用相移控制,即可實現軟開關,因此引起關注。After the nonlinear and absorption effect is taken into account in the applications where high power ultrasonic is involved, the first and second harmonic components of the sound field of stepped circular plate is analyzed, based on the kzk equation and quasi - linear condition
