同时考察了温度、流动相中的极性改性剂的种类及结构对手性拆分的影响。

In the system of A-D phenothiazine derivatives, the transition dipole moments M flu were determined mainly by direct interactions between the solvent-equilibrated fluorescence 1CT state and ground state because of their lack of significant change with increase of the solvent polarity.

在此吩噻嗪衍生物的体系里，荧光过渡态偶极矩主要由溶剂平衡的电荷转移态和基态间的作用所决定，因为它在不同极性的溶剂中缺乏明显的改变。

In the study of peptide formation from phosphoryl aspartic acid with ethyl alanine, the N-phosphoryl peptide ester was isolated and identified by 1D and 2D NMR. It was found that only α-dipeptide ester, no β-dipeptide ester, was formed in the reaction.

实验发现N-磷酰化极性氨基酸在没有活化剂、缩合剂的水溶液中能够发生成肽反应，且生成的磷酰化二肽具有方向性：成肽产物的N端氨基酸来自N-磷酰化氨基酸，成肽反应发生在其C端。

Among the arylazides, fluorinated aryl azides are exceptionally promising because upon photoactivation, they lead to much more efficient photolabeling than non-fluorinated arylazides.

目前，尽管已经有一些磷脂光敏探针用于膜蛋白研究的报道，但是还没有使用以上两种芳基叠氮基团作为光敏基团的报道，在磷脂的极性头基上引入光敏基团的报道也极少见。

高光能、低偏置电场下，空间电荷电场是造成光电导天线辐射的THz波呈现双极性的主要原因。

In this study, Naproxen was placed in a polar solvent, such as methanol, while it exposed to high pressure mercury lamp, it undergoes photodegradation. The photodecomposition products were separated and identified using UV, IR, MS and NMR spectroscopies.

研究中将NAP置於极性较高之甲醇溶媒中，当暴露於高压汞灯下，会进行光解反应，利用质谱仪、熔点测定仪、紫外线光谱仪、红外线光谱仪、核磁共振光谱仪进行光解产物结构的鉴定。

The spectra properties in different solvents with various polarities, photooxidation ability andDNA photocleaving ability of these compounds were investigated.

对合成化合物的紫外—可见光吸收光谱及荧光光谱进行了研究；并对它们与溶剂极性的相关性作了探讨。

Results: the positive cells mostly included ependymal cells of myelocoele, glial cells, anterior horn motor neurons, and epithelial cells of spinal pia mater and their expressions were mainly located on cell membrane. interestingly, aqp4 distribution in glial cells and ependymal cells showed certain directivity, but the former was mainly in the membrane side contacting with capillary endothelial cells and the latter mostly in the basolateral membrane of ependymal cells.

结果： 免疫组织化学染色和原位杂交结果显示胶质细胞、前角运动神经元、中央管室管膜细胞、软脊膜上皮细胞均表达阳性，aqp4主要分布于细胞膜，其中，胶质细胞和中央管室管膜细胞表达存在极性，前者主要分布在与毛细血管内皮细胞接触的一侧，后者主要分布在中央管室管膜细胞的基底侧膜。

Simulation results show that this method is feasible and can pick-up the polarity information of PD under strong interference.

仿真表明，该方法是可行的，并可在强干扰下提取局放信号极性信息。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
