  3. Lc oscillators have better phase noise, but the lowest noise is obtained with the use of a quartz crystal oscillator

    Lc器利用石英晶體器產生基源,因此抖動較小。
  4. 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時的演化規律進行了比較.我們發現失對時間演化規律有顯著的影響;當驅動場或探測場失時,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阻尼子的演化規律;驅動場色散驅動場失量的增加而時間變長,幅和穩定值變大
  5. In the course of the low phase noise research, by integrating many aspects, using recent accomplishments, i come up with my method and theory, that by comprehending and controlling subcircuit of oscillator ' s resonator, can let us know exactly their working states. using this method and theory, combining the vco circuit of this subject, i deduce and demonstrate particularly the reason of low frequency oscillation, and come up with the measure of avoiding it. this makes design and producing vcos can avoid the disturbing of low frequency oscillation, and improve the features of vcos. at later process of debugging vco, using this method makes the vco achieves very good working state

    在低相噪研究中,綜合了各方面的情況,運用了當今低相噪vco的研究成果,並提出了自己的對電路結構進行總體把握,從而確得知電路的工作狀態的思想和理論。運用此方法,在論文中結合本vco電路拓撲結構,詳細推導和論證了低頻產生的原因,並提出了避免發生低頻的措施。使低相噪vco的設計及調試能免於低頻的干擾,從而有利於提高vco的各項指標。
