| 1. | Charge-separated resonance structures do not contribute very much to the resonance hybrid of butadiene . 电荷分离的共振结构对丁二烯没有很大的贡献。 |
| 2. | Fourthly , the resonance structure disappears in the energy dependence of integral cross - section due to the summation of partial waves 另外在积分散射截面中,由于对各个分波求和,能量几率曲线的振动结构消失了。 |
| 3. | This resonance structure results from the interference between a photoionization process or a photoionization with excitation process and a resonant auger process 这一共振结构是由于光电离过程或光电离激发过程与auger共振过程相互作用的结果。 |
| 4. | Second , negative dispersion without absorption , which leads to superluminal light propagation , is achievable in the central resonance structure of the dispersion spectrum . the negative dispersion is slightly weakened as the spacings between dressed states increase 其次,在色散光谱的中心区域,呈现出无吸收负色散,这种效应能够导致超光速传播,但它随着修饰态间距增加而减弱。 |
| 5. | This dissertation concentrates on photoionizaiton of mnl and mnll including resonance structure in the framework of many - body perturbation theory ( mbpt ) . more accurate results were obtained by using the new approach to calculate resonance structure and photoionization cross section 首先针对锰原子或离子不同壳层的光电离结构进行特定的理论分析,然后通过合理的选择势能及共振结构的计算方法,并考虑高阶关联,得到了一系列新的更为精确的光电离截面及共振结构。 |
| 6. | To solve this problem , higher order diagrams were included after detailed mathematic preparation and physical interpretation . in order to see their effect and to avoid the " black box " working style of cem , these diagrams were added to cem one by one . comparison is made with experiment and the results show that higher order diagrams decrease the diverged resonance structure effectively 针对garvin计算的锰原子里德堡共振结构过于发散,以至于物理上不易接受的问题,我们有效的分析了多体微扰理论中的二阶基态关联图式、 rpa图式以及auger图式,建立了相应的算法和程序,并明确地给出了这些高阶图式的物理意义。 |
