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激發態下的單、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；在中心和受體一定的情況下，增加給體的供電子能力，可提高雙光子吸收強度。 -
We get to the conclusions : ( 1 ) the histon acetylation level has some derease in the lung of cloned cattle ; ( 2 ) in the cloned cattle xiaobai, the histone acetylation level is lower than that in normal control, however, higher or adjacent to that in other dead cloned cattle ; ( 3 ) there is no significant difference during those cattle from the cumulus, fetal fibroblast and adult fibroblast cell donor
我們發現： （ 1 ）在克隆牛中組蛋白乙酰化水平基本上都有所降低； （ 2 ）克隆牛xiaobai乙酰化水平比正常牛低，而基本上是高於或接近死亡克隆牛水平的； （ 3 ）在我們所研究的三個供體細胞系（卵丘細胞，成體成纖維細胞和胎兒成纖維細胞）中，乙酰化水平無明顯差異。 -
One common approach is to match the anticipated organizational expenses to the level of support the organization expects to receive from a specific donor
一個通常的方法就是權衡組織期望的成本和組織從特定捐款人期望獲得的資金支持。 -
Photoluminescence characteristics of four hemicyanine derivatives with similar molecular compositions but different donor - acceptor groups in langmuir - blodgett ( lb ) films have been studied by steady state and time - resolved fluorescence spectroscopies. the study mainly include the aggregation behavior of hemicyanine derivatives in lb films, the influence of the donor - acceptor on the excited level and excited lifetime of the hemicyenine derivatives

To support and promote the achievement of plan china ' s goals in program quality, growth, customer satisfaction, grant and program development, and the establishment of an effective working relationship with county level program offices, donor countries, and plan headquarter & regional office
支持和促進各項國家目標的實現，如：組織成長，使客戶滿意，贈款和項目發展，與各項目辦公室、各資助國以及地區辦公室等建立有效的工作關系。 -
We also have analyzed the photoluminescence ( pl ) spectra of some zno films, it turns out that the emission of ultraviolet light comes from the radiative recombination of excitons within nano - crystal energy band - gap, and the pl peaks move to smaller wavelength because zn are substituted by fe, co, and cu, which cause the size of the film grains smaller and the effective band - gap bigger. the red emission of zno films is due to, on the one hand, decrease of the film grains size which causes the emission intensity smaller and smaller until it disappears abruptly, on the other hand, the transition of electrons from deep donor level of the oxygen vacancies to the valence band
另外，我們還對薄膜光致發光性質進行了分析和研究，結果表明：納米結構zno薄膜的紫外發光來源於帶間激子的輻射復合發光， pl譜的帶邊發射峰發生藍移是由於fe 、 co 、 cu對zn的替代使薄膜粒子的尺寸減小，使薄膜的有效帶隙增寬； zno薄膜的紅色發光，一方面是zno顆粒尺寸的減少，帶間的激子發射峰越來越弱直至猝滅，另一方面主要是與zno晶格中的o空位有關，由深能級復合發光引起紅光發射。 -
