low excited state meaning in English
低激发态
Examples
- In the course of scattering with the same energy , the excited probabilities of lower exciting states are far off bigger than ones of higher exciting states . all in all , the adapted ms potential has advantages of concision form , less adjustable parameters , convenient for applicant
当体系能量一定时，不管是微分散射截面还是分波散射截面，弹性散射的几率大，对总的散射截面贡献最大；非弹性散射的几率小，对总的散射截面的贡献也小。 - It has important theoretical meaning for reflecting the research of the interaction potential of nuclear force has important theoretical meanings in the framework of glauber theory and distorted wave impulse approximation ( dwia ) , being spin - independent , inelastic scattering three low exciting states ( j * = 2 ~ ( + ) , 4
本工作的目的是借助反质子-核散射来探索反核子-核子相互作用势的最佳形式及相应的势参数，对反映核力的相互作用势的研究具有十分重要的理论意义。 - We have calculated one - and two - photon absorption cross sections of the lowest excited states of a series of molecules combined with benzene , stilben , thiophene as center attached with amine , diphenylamine , diethylamine as electron - donor and nitryl as electron - acceptor ; the effects of molecular length , n center and electron - donor on two - photon absorption cross sections have been studied and all calculations have been carried out using the density functional theory at an ab initio level . it is found that the molecular length and the one - photon absorption intensity are quite strongly c orrelated factors , and that a corresponding correlation for the two - photon absorption is decreasing . it is also found that a most crucial role for the two - photon absorption is played by the n center
我们分别以苯、二苯乙烯、噻吩为中心，氨基、二苯氨基和二乙氨基为电子给体，硝基为电子受体组合形成的分子为研究对象，在从头计算的水平上用密度泛函理论计算了这些分子在低激发态下的单、双光子吸收强度，重点研究了分子的长度、中心和给体的供电子能力对分子单、双光子吸收的影响。研究结果表明，分子长度与单光子吸收强度之间有密切关系，而在双光子吸收中这种关系较弱；中心在双光子吸收中具有重要的作用；在中心和受体一定的情况下，增加给体的供电子能力，可提高双光子吸收强度。
