Intestinal tra it time can influence drug a orption, particularly for drugs that are a orbed by active tra ort, that di olve slowly, or that are too polar （ie, poorly lipid-soluble） to cro membranes readily.

肠道通过时间肠道通过时间能影响药物吸收，特别是经主动转运吸收的药物、溶解缓慢的药物，或极性太高难以透过细胞膜的药物。

Cell polarity plays an essential role in the tissue development and organogenesis.

细胞极性是真核细胞的一种基本特征，决定细胞形态和胞质大分子的不对称分布川。

Secondly, femtosecond time-resolved studies using fluorescence depletion spectroscopy were performed on Rhodamine 700 and Oxazine 750 in solutions to study the ultrafast dynamics, such as vibrational relaxation and the energy transfer from the solute to solvent. The orientational relaxation process of these dye molecules have been study in solution by the polariton resolved FS TR SEP FD.

我们利用此技术，对LD700和OX750两种染料分子电子激发态的振动弛豫和溶质与溶剂分子间碰撞传能等超快动力学过程进行了详细地实时研究，获得了它们的激发态分子在不同溶剂和体系温度等实验条件下的飞秒时间分辨荧光亏蚀谱：并首次采用极性分辨的飞秒荧光亏蚀光谱技术研究了溶质的取向弛豫过程。
