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The characteristics of damping shows that the uncompensated parallel ac transmission line can release the coupling between the hvdc and generator and improve the damping of the system, hence the possibility of subsynchronous oscillation decrease. in such a system scheme, the hvdc system dominates the changes of damping due to the small magnitude of the damping provided by ac line. when the ac transmission line is compensated with a fixed series capacitor, the situation will be totally different
