Finally, the atomic coherent population trapping is studied in a multilevel laser - induced continuum structure system including cascade two - photon processes by means of quasi - classical theory. the condition leading to the atomic coherent population trapping and the dark state are given explicitly. the effects of atomic initial state and the laser intensity on the populations distributed in the atomic bound states are discussed
我們還運用準經典理論研究了含級聯雙光子過程的多束縛態激光場誘導原子連續態結構系統中原子布居數的相干俘獲，給出了產生相干俘獲的條件及暗態的表達式，討論了原子初態和激光強度對原於布居數的影響，揭示了原子相干對穩定rydberg原子的重要作用。 -
At the other hand, we can perform the rrpa calculation with the continuum replaced by a set of outgoing single particle resonances, it indicates that the resonances in the continuum play an important role in the description of nuclear dynamical processes, such as collective giant resonances. energies, widths and wave functions of the single particle resonant continuum are determined by solving scattering states of the dirac equation with proper asymptotic conditions for the continuous spectrum in the r ' elativistic mean field theory. the relativistic regular and irregular coulomb wave functions are calculated numerically
在進行相對論無規位相近似計算時將連續譜中所有的正能態用單粒子共振態來代替，並且在計算中採用單粒子共振態的真實寬度，利用這種方法我們計算了核的同位旋標量巨八極共振響應函數，並且和考慮了連續譜中所有正能態貢獻的結果進行比較，計算結果表明，連續譜中只考慮單粒子共振態對核的集體激發的貢獻時，給出的響應函數基本上能夠重現考慮了所有正能態貢獻時的計算結果，這說明了在核的集體激發中，連續譜中主要是單粒子共振態的貢獻。 -
Secondly, the nonlinear optical properties with pna molecule in different solvents are studied through using the polarized continuum model and few states approach on the base of time dependent density functional theory, and the first order nonlinear hyperpolarizabilities in second harmonic generation process are computed
然後在含時密度泛函理論基礎上採用極化連續模型和少態方法研究了不同溶劑中pna分子的非線性光學性質，計算了二次諧波振蕩過程的一階非線性超極化率，並討論了pna分子的非線性光學性質與溶劑極性之間的關系。 -
The resonance states in the continuum for some stable nucleus in sn - isotopes and nucleus in ca - isotopes are calculated. the results show that the s - matrix method is a reliable and straightforward and feasible way in the determination of single particle resonances
千用該方法研究了h同位素鏈的幾個穩定核和h同位素的連續譜，給出了這些核所有的單粒子共振態的能量和寬度。 -
Uv - vis and pl spectra were used to study the energy band structure and the holding states of light - induced - electrons of tio _ ( 2 ) powder and films prepared by magnetron sputtering. the energy band structure and light - induce - electrons holding states were studied by pl spectra, conduction band and impurity energy levels were emerged together and formed a new continuum band
導帶和雜質帶連到一起形成了連續帶?雜質能帶，光生電子並不是位於導帶之上，武漢理工大學碩士學位論文而是占據了2 . 5一3 . sev的連續帶上，主要集中於2 . 65一3 . oev之間。 -
