At the same time , the solvent effect of 4 , 4 ' - bis ( dimethylamino ) stilbene is carried out by the polarized continuum model ( pcm ) , the pcm is selecting the solvent cavity ' s form to be the form of solute molecule ' s . and after that , we used self - consistent reaction field method calculate the molecule ' s tpa property 同時，本文還采用極化連續模型( polarizedcontinuummodel ) ，把包圍在有機分子周圍的溶劑空腔的形狀取為溶質分子的形狀，利用自洽響應場方法( self - consistentreactionfieldmodel )研究了溶劑對4 ， 4 -二甲氨基二苯乙烯分子的雙光子特性的影響。
The molecules we studied are a series of trans - stilbene derivatives . first , we applied dft method optimized the new synthesis molecule 4 , 4 ' - bis ( dimethylamino ) stilbene ' s structure , and used few states model calculated its tpa cross section . the results agree well with the experiment data 首先，我們在密度泛函理論( densityfunctiontheory )的水平上對最近合成的分子材料4 ， 4 -二甲氨基二苯乙烯的結構進行了優化，然后采用少態模型方法計算了分子的雙光子吸收截面，得到了與實驗符合很好的結果。
As a popular vegetable , tomato is rich in vatamin a , b , p and other nutrients ; among them , lyxopene can prevent prostate gland tumor . so introducing stilbene synthase gene into tomato to get new health - protection tomato will have important social and economic effect . our research is made up of four parts ; the cloning and sequencing of stilbene synthase ; tomato genetic transforming mediated by agrobacterium - lba4404 ; quantification of resveratrol in transgenic tomato by hplc analysis 本研究包括四個方面的內容：芪合酶基因( stilbenesynthasegene )的克隆與全序列分析；芪合酶基因( stilbenesynthasegene )植物表達載體的構建；農桿菌lba4404介導的番茄遺傳轉化： hplc技術分析轉基因植株中表達白藜蘆醇的含量。
Deduced amino acid sequence of s1 , s2 , pvin were also highly homologous each other ( 98 % , 99 % in each case ) . the stilbene synthase genes were excised from the plasmids by bamh i and sac i digestion and intergrated into a binary vector , pbi121 and pev2 , from which the p - glucuronidase ( gus ) gene sequence had been removed by the same digestion to prepare a 35s promoter - stilbene synthase 2 - nopaline synthase polyadenylation site construct and a tfp2 promoter - stilbene synthase 1 - nopaline synthase polyadenylation site construct . the recombinant plasmids were called pbs2 , pev2s 1 . respectively 用bamhi和saci同時酶切ps2 ( s2表示來自雷司令的芪合酶基因) 、 ps1 ( s1表示來自粉紅玫瑰的芪合酶基因)以及pbi121 、 pev2 ，使得s2 、 s1分別插入替代pbi121 、 pev2中的gus基因，構建成植物表達載體pbs2 、 pev2s1 ， pbs2中含camv35s組成型啟動子，使s2基因能在番茄植株的各個部位表達； pev2s1則含有果實特異性啟動子tfp2 ，使s1基因只在番茄果實中表達。
Stilbene synthase genes ( l , 2 ) from vitis venefera were cloned and sequenced . the results of sequence analysis showed the total length of s2 is 1617bp , the homology between s2 and pvin ( reported ) is 99 % ; the total length of si is 1622bp , the homology between si and pvin ( reported ) is 98 % Dna序列分析結果表明，來自雷司令的芪合酶基因全長1617bp ，與文獻報道的該基因( pvin )比較，堿基同源率為99 ，來源于粉紅玫瑰的芪合酶基因全長1622bp ，與pvin的序列比較，堿基同源率為98 。
The spectrum evolution of the femtosecond laser pulse in a three - level organic molecular medium ( 4 , 4 ' - bis ( dimethylamino ) stilbene ) is studied theoretically by solving the maxwell - bloch equations using an iterative predictor - corrector finite - difference time - domain method 摘要通過采用預估校正的時域有限差分法求解麥克斯韋布洛赫方程，我們研究了飛秒激光脈沖在三能級有機分子（ 4 , 4 ' -二甲氨基二苯乙烯分子）介質中傳播時脈沖的頻譜演化情況。
At last , the structure - to - property is researched , we design a series of trans - stilbene derivatives with different arrangements of the substitutions and study their two - photon absorption properties by using the response theory method at hf level 最后，本文選取了一系列不同官能團取代的具有不同對稱性的二苯乙烯系列衍生物，對其雙光子吸收截面與分子結構之間的關系進行了研究。
For molecules with a given n center strong donors can result in the increasing of tpa cross sections . by caculation the d - a - a - d molecule which is constituted of bipyridine inserting in the middle of stilbene as center exhibits a maximum tpa cross section 通過計算發現，在以二苯乙烯為中心的中間插入兩個氮苯構成的d - a - a - d型分子，具有最大的雙光子吸收截面。
In this thesis , we design a series of trans - stilbene derivatives and study their two - photon absorption properties by response and few states model . the work is done on dalton and gaussian - 98 program packs 本論文中；我們選擇二苯乙烯系列衍生物作為研究對象，分別采用響應場方法和少態模型方法研究了它們的雙光子吸收性質，計算過程分別在dalton和gaussian
