In compared with acceptor emitters, not only can the emission wavelength be tuned (up to 100 nm of red-shift) by H-bonds, but also much higher emission efficiencies of the H-bonded complexes were induced by reduced aggregation and energy transfer from the OXD donor dendrons.

另外，在使高分子形成高分枝结构之研究上、利用不同含量与不同官能基数目之carbazole单体与茀单体进行聚合，可得一系列高分枝状高分子，能使聚茀共轭高分子产生不同之分枝程度结构，这样方式有效改善分子间聚集之现象并且维持高分子主链良好共轭程度，使得产生之高分子具良好的萤光效率。

The results show that the maximum CLA content is 15.4 g CLA per 100 g isomerized rapeseed oil and the characteristic peaks of CLA in CLA standard as well as isomerized rapeseed oil are found at 234 nm at 25 ℃. A linear regression equation is obtained.

4g，利用紫外分光光度法测定的共轭亚油酸标准品和异构化菜油在25℃条件下的最大特征吸收峰波长为234nm，并建立了线性回归方程，因此，只要测定油样在234nm的吸光度再依此方程可算得油样中共轭亚油酸的浓度。

Wheares under buffer pH5.2, there is no strong static electricity and instead being a longer wavelength movement; SDS\'s participation just restricts the relative movement of heme\'s ethylene; a new fluorescent peak forms and the reduction of enzymatic activity is due to the packing of micella\'s formation.

强变性的阴离子表活剂SDS与带净正电荷和弱负电荷的SBP(处于pH2.6和4.2缓冲液中)有强烈的静电力作用，酶活力丧失，二级结构变化，荧光强度增加，特征Soret发生蓝移，卟啉环的π-π*共轭的分裂能增大；而当SBP带净负电荷(pH5.2)时，没有静电吸引力，Soret带发生红移；SDS的引入只是限制了血红素上乙烯取代基的运动，使其与卟啉环共轭：极性环境的变化导致产生新的荧光峰；酶活力因胶团包裹作用而有下降。

Hydrolysis of the mischarged amino acids in theediting reaction will rely on the proper binding and correct recognition of both mainchain and side chain of the substrate. In general, the editing active site ofLeuRS-ED has a very rigid structure with a defined stereochemistry and usesa number of conserved residues to precisely bind and recognize the misactivatedamino acids and discriminate and reject the cognate amino acid, specifically usingMet336, Asp345, and possibly Thr247 for main-chain recognition and Thr252,Met336, and Val338 for side-chain recognition.

在编校反应中错配的氨基酸的水解依赖于对底物主链和支链的适当的结合和正确的识别。ecLeuRS-ED的编校活性位点有一个非常刚性的有很精确设计的立体化学性质的结构，采用一系列保守氨基酸残基来精确结合和识别错配的非共轭氨基酸而区分排斥正确的共轭氨基酸，具体就是采用Met336、Asp345，另外可能还有Thr247对底物主链进行识别，采用Thr252、Met336和Val338对支链进行识别。
