英文

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。Polymer his - tagged peac1 - gfp efficiently activated myosin mg - atpase activity, which indicated that peacl might take part in correlative living activities in vivo. moreover, this result provided experimental proof in vitro for fusing gfp to actin isoform directly to study the dynamics of microfilaments and its regulation in vivo. we prepared rabbit anti - pea actins polyclonal antibodies using peacl as antigen which being expressed and purified from prokaryotic cells, and the antibodies possessed better immunity activity to pea actins

單一的評價方法脫離了學生的心智發展，脫離了語文本身的文化屬性和審美屬性。語文課程評價的目的最終是為了促進學生語文素養的形成和發展。本文針對現行語文學習評價方法的局限性，以《全日制義務教育語文課程標準（實驗稿） 》為依據，從知識與能力、過程與方法、情感態度與價值觀等維度，對識字與寫字、閱讀、寫作、口語交際、綜合性學習五個方面，關注學生語文學習過程，在實踐中探求評價主體多元、項目多種和形式多樣的形成性評價方法，充分發揮評價的診斷、激勵、反饋等功能，有效地促進學生發展。It is the main purpose of this paper to calculate the energy splitting of ground state and excited states induced by thermally assisted quantum tunneling. first, a brief introduction is given for the theoretical and experimental studies on the magnetic macroscopic quantum effects. then, spin tunneling in a uniaxial ferromagnetic particle in transverse magnetic field is converted to a pseudoparticle moving in effective double - well potential with the help of the effective potential description of quantum spin systems developed by ulyanov and zaslavskii. finally using the periodic instanton method we evaluate the transition amplitude, energy shift and prefactor of wkb exponential and the energy splitting of ground state and the tunneling rate for excited states induced by thermally assisted quantum tunneling are obtained

此外，由於ifn y單獨作用也可促進兩種細胞因子基因表達，故在巨噬細胞中加入ifn y單獨作用22h ，再經阿一pcr檢測，發現加ifn y的實驗組細胞的幾一lp和tnf a基因轉錄水平與空白對照組相比較無顯著性差異，可見，殼寡糖和ifn v對巨噬細胞il lp和tnf一口基因轉錄水平的影響在作用時間上無一致性，在殼寡糖作用最適時間時，僅受ifn y刺激的巨噬細胞il lp和tnf q基因轉錄己下降至刺激前水平，因此可以認為， ifn y的加入僅起到對巨噬細胞預刺激使之處于敏感狀態的作用，有利於增強殼寡糖對巨噬細胞的作用。Based on the above theory, the fluorinone - based azo was used to prepare the single - layer photoreceptors with fluorinone - based azo / tiopc composites in chapter iv, experimental data indicated that the photoconductivity of fluorinone - based azo / tiopc composite photoreceptors was improved in comparison with that of chlorodiane blue azo / tiopc composite photoreceptors, the amelioration was attributed to the more pronounced electron - acceptor characteristic of fluorinone - based azo, these results further confirmed the mechanism proposed for the synergetic enhancement and complementary effects in azo / tiopc composite systems
