※中文詞彙第一激發態在字典百科國語字典中的解釋。

  1. By comparing theoretical predictions with experimental data, one can obtain a valuable information on the form of the qq interaction potential. such information is of great practical interest, since at present it is not possible to obtain the quark - antiquark ( qq ) potential in the whole range of distances from the first principles of qcd

    夸克勢模型是其中重要的模型之,它不僅能研究強子的基,而且能研究,但是,源於在中和大距離與qcd真空的復雜結構有關的非微擾特徵,還不可能獲得整個距離范圍內的夸克?反夸克相互作用勢。
  2. 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

    我們分別以苯、二苯乙烯、噻吩為中心,氨基、二苯氨基和二乙氨基為電子給體,硝基為電子受體組合形成的分子為研究對象,在從頭計算的水平上用密度泛函理論計算了這些分子在低下的單、雙光子吸收強度,重點研究了分子的長度、中心和給體的供電子能力對分子單、雙光子吸收的影響。研究結果表明,分子長度與單光子吸收強度之間有密切關系,而在雙光子吸收中這種關系較弱;中心在雙光子吸收中具有重要的作用;在中心和受體定的情況下,增加給體的供電子能力,可提高雙光子吸收強度。
  3. In the neon - filled franck - hertz experiment, the experimental value gravely deviates from the value of the first excited state because of the effect of highly excited state and bremsstrahlung

    在充氖夫蘭克赫茲實驗中,由於高和軔致輻射的影響使實驗值嚴重偏離第一激發態值。
  4. Those investigations have improved one ' s understanding of the structure, formation conditions, reaction mechanisms, and excitation modes of halo nuclei. inl990 ' s it was predicted that besides the ground state of the light nuclei near the drip line, the high isospin excited states may also have halo structure

    除滴線附近輕核的基外,九十年代有人預言穩定核的高同位旋也可能具有暈結構, ~ ( 13 ) c第一激發態和~ 6li被列為首選的研究對象。
  5. The results show that the contribution of direct capture is primary in the interested temperature range of astrophysics. toward the 12c ( n, y ) 13c reaction, our calculations are good agreement with a recent experiment at low energy. a obvious enhancement of the cross section of 12c ( n, y ) 13c first excited state has been found, and it supports that the first excited state 1 / 2 + of 13c is a neutron halo state which has been found experimentally by our department group

    對于個核反應,我們計算了直接俘獲過程以及兩個共振的俘獲截面和總截面,我們的計算結果顯示,在天體感興趣的溫度范圍內,直接俘獲過程對總截面的貢獻是主要的;對于二個反應,我們的計算結果與已有的實驗結果符合的較好,其中~ ( 12 ) c ( n , ) ~ ( 13 ) c的第一激發態計算結果顯示出截面有明顯增大,這從理論上支持了我所關于~ ( 13 ) c第一激發態具暈結構的實驗現,這是國際上次在現暈結構。
