Fast time constant
快速時間常數電路 -
We present a charge - transport model of the photorefractive effect with two deep traps ( two deep - trap model ) based on one deep - trap model and shallow - deep - trap model. we also found dark decay behaviors which accord with the two deep - trap model in the two - beam interference experiments. the fast decay - time constant of the space - charge field is obtained as 714s
此外，在ce ： batio _ 3雙光束干涉光折變光柵的暗衰減實驗中，也觀察到了符合雙deep模型的衰減現象，得到光折變空間電場快衰減時間常數714s ，約12分鐘。 -
Since reforming and opening - up, not only gdp keeps growing at top speed for a long time in our country, but also foreign trade has been keeping high - level and increasing continuously all the time, the international competitiveness of the products is strengthened day by day, the imported and exported commodities are diversified day by day, constant enlargement opening to the outside world and participating in the international division in an all - round way are already becoming strong motive force of promoting the economy of our country to develop continuously fast
改革開放以來，中美貿易關系不斷發展，相互間的貿易依存度不斷提升，貿易商品結構也出現了重大變化。中美貿易關系的發展對兩國比較優勢的發揮和人民經濟福利的提高具有極為重要的意義。但由於美國方面對華一直實行歧視性的貿易政策，致使中美貿易摩擦頻繁發生。 -

Haloes in the two accretion phases show systematically different properties, for example, the circular velocity vh increases rapidly with time and approximately equals the inner circular velocity vs in the fast accretion phase, but remain almost constant and less than vs in the slow accretion phase : the inner properties of a halo, such as rs and ms increase rapidly with time in the fast accretion phase but change only slowly in the slow accretion phase : the halo concentration changes slow in the fast accretion phase, but increases rapidly with the hubble expansion in the slow accretion phase. the inner structure and potential well associated with a halo is built up mainly in the fast accretion phase, while a large amount of mass can be accreted in the slow accretion phase without changing significantly the inner properties and the potential well
~ 4 ，其束縛能和具有相同圓周速度的等溫球大致相等; （ s ）在這兩個階段，暗暈的行為特徵迥異（例如，圓周速度均『在快速吸積階段增長迅速且略大於內部圓周速度: 、 ，而在緩慢吸積階段基本恆定甚至降低，且小於、 、 . : 、和呱在快速吸積階段增長迅猛，而在緩慢吸積階段增長滯緩） : （ l ）一個暗暈的內部結構和引力勢阱主要是在早期的快速吸積階段成長起來的，雖然在緩慢增長階段可以吸積大量的質量（超過10倍） ，但這並不顯著地改變其內部特徵和引力勢阱
