The correlation of such ultrafast process with the system temperature and property of solvents is analyzed, which is useful for the further study about the ultrafast process of DNA, protein and other biological molecules, such as intra- and intermolecular electron, proton and energy transfer and photoisomerization.

本文的主要内容是利用飞秒时间分辨荧光亏蚀光谱探测技术对液相体系中的染料大分子在不同条件下的激发态振动弛豫、取向弛豫和分子间碰撞传能等超快动力学过程进行了研究，分析得到了这些超快过程与体系温度和溶剂性质之间的关系，同时为进一步研究DNA、蛋白质等生物分子体系的电子转移、质子转移、能量传递以及光致异构化等反应过程打下了基础。

Optical control of the primary step of photoisomerization of the retinal molecule in bacteriorhodopsin from the all-trans to the 13-cis state was demonstrated under weak field conditions (where only 1 of 300 retinal molecules absorbs a photon during the excitation cycle) that are relevant to understanding biological processes.

在弱场条件下（整个兴奋周期中，300个视黄醛分子中只有一个吸收光子），细菌视紫红质中视黄醛分子的从全反式到13－顺式状态的光致异构化的最初阶段的光学控制被阐明，这与生物学过程的理解有关。

Femtosecond time-resolved studies using fluorescence depletion spectroscopy were performed on the vibrational relaxation; orientational relaxation and the intermolecular energy transfer of dye molecules in solutions under different conditions. The correlation of such ultrafast process with the system temperature and property of solvents is analyzed, which is useful for the further study about the ultrafast process of DNA, protein and other biological molecules, such as intra- and intermolecular electron, proton and energy transfer and photoisomerization.

Nevertheless, the yield of pinacol was also strongly affected by the steric environment surrounding the carbonyl group. The pinacol coupling of aromatic aldehydes has been achieved with high yields under such a condition. However, the diastereose-lectivities of pinacols were not satisfying. Unfortunately, the ketones and most aliphatic aldehydes appeared inert under the same reaction conditions.

然而， 呐偶合反应的产率受到羰基周围环境的立体位阻影响较大，在此条件下，锌粉能有效地促进芳香族醛类化合物进行水相呐偶合反应，得到的呐醇产率高，但非对映异构体选择性差，而脂肪族醛类化合物得到的呐醇产率较低，在同样的条件下，酮类化合物不能顺利进行呐偶合反应。

We have demonstrated that the expression of protein kinase Cisoform are associated with the development of deciduomata in the pseudopregnant and pregnant rats.

我们过去的研究中已经发现，在蜕膜的形成过程中，不论是在真怀孕或假怀孕大鼠蛋白激酵素C异构体都参与其中蜕膜的形成，因此我们猜测PKC可能参与调节蜕膜细胞的增殖。

The concentration of enantiomers was positively related to the maintenance dose of warfarin, but not to drug response. It is not applicable to adjustment of the dose by monitoring the concentration of racemic warfarin, or to its enantiomers.

异构物浓度与维持剂量间有显著的相关性存在，但与疗效间却没有直接的相关，故无法以监测浓度的方式来调整病患之剂量，仍需采用临床上使用的INR值来监测。

Resultingly CORBA has its own software bus point, it can easily solve the problem about the capability of heterogeneity and adaptability.

系统引入分布式CORBA技术，利用CORBA的&软件总线&的特点，很好的解决系统平台的异构性、适应性的问题。

Among them, the catalysts with the support of SAPO zeolite performed well properties, Pt catalysts exhibited better performance than Pd catalysts, the activity and selectivity of noble catalysts were much better than that of non-noble metal catalysts. The carbides and oxides of W and Mo also performed well for n-heptane isomerization.

正庚烷异构化催化剂中，研究较多的是以SAPO、HZSM-5和Y、β型分子筛为载体的贵金属催化剂，其中SAPO分子筛载体的性能较优，Pt比Pd具有更好的催化性能，非贵金属／分子筛催化剂的活性比贵金属／分子筛催化剂相差较大。
