Hydrogen bondings induced from carboxylic groups were intentionally designed at the end of the arm of these star-shaped molecules. The hydrogen bonding positions of the so-perpared star-shaped oligofluorenes were similar to those of trimestic acids which has been intensively studied, and this enlightened us to design these moleucles.

S-1-phenylethanol was obtained in up to 19%ee in toluene at 0℃.(4)A series of C_2-symmetric chiralβ-amino alcoholsⅣ-5were synthesized in several steps from natural amino acid L-proline,and applied in the asymmetric borane reduction of prochiral ketones.

4以天然L-脯氨酸为起始原料，经过几步转化合成了以萘环为母体的C_2-对称的手性β-氨基醇Ⅳ-5，将其应用于硼烷对前手性酮的不对称还原反应中，同样，我们也观测到温度影(来源：Ac1BC论文网www.abclunwen.com)响产物构型的现象。

The concents of testosterone and NO of the mouses gavaged with high dosages of Chinese chive extractiong were not significantly more than that of giving middle dosages.This indicated that Chinese chives might be more safe than traditional chinese herbals of sexual improvement function.2、The screening of sexual improvement function chemical substances of Chinese chivesThe crude extract was leached to four phases by petroleum ether, ethyl acetate,n-butanol and water.By doing animal tests to detect the contents of testosterone and NO in serum of mices,the result was showed that the extracts of petroleum ether and n-butanol have sexual improvement function,especial the n-butanol phase.

从小鼠灌喂不同剂量的韭菜提取液试验结果来(来源：ABCa539a5论文网www.abclunwen.com)看，灌胃高剂量的小鼠的睾酮含量和NO含量相对于中剂量来说并不上升，而是保持稳定，因为睾酮含量和NO含量过度上升可能会带来付作用，所以由此可以说明其食用安全性高，副作用小。2、韭菜改善性功能物质的筛选将韭菜粗提物依次通过不同溶剂萃取，分成石油醚、乙酸乙酯、正丁醇和水四个萃取相，通过小鼠灌胃的动物试验，以小鼠血液NO含量和睾酮含量为指标，发现正丁醇和石油醚萃取相中的物质有改善性功能的效果，尤其是正丁醇相效果非常显著。

In this way, much potential interference may be avoided in the determination of these drugs in biological materials and hemanalysis. These methods are rapid, simple and wider linear range, and can be used for determining procaine hydrochloride, dapsone and ampicillin sodium in injectin solutions of these drugs. The results obtained by these methods agreed with those by the official methods.A sensitive and selective method for the determination of dopamine was studied.

在此反应的基础上，实验(来源：6aABC论文网www.abclunwen.com)了pH值、表面活性剂、有机溶剂、加热时间、放置时间及干扰离子对测定的影响，所建立的方法具有线性范围宽，稳定性好等特点，可成功地用于相关药品含量的测定，与药典方法对照，结果吻合。

When energy transfer systems were obtained from the interaction of G1.0, G1.0, G and G2.0 with eosin or Eu~(3+) ion respectively, all the dendrons could partially transfer their absorbed energy to eosin and Eu~(3+) ion at a certain range of concentrations.

将G1.0、G1.0、G(来源：c2ABC论文网www.abclunwen.com)、G2.0分别与曙红或Eu~(3+)离子构成能量转移体系，发现在一定的浓度范围内，这些树枝块均可以将吸收的能量转移给曙红和Eu~(3+)离子，使曙红和Eu~(3+)离子的特征发射强度增强，曙红的荧光强度最大增强为原来的2.5倍；Eu~(3+)离子的荧光强度最大增强为原来的11.7倍。

In fact, in reallife, the prey species will be usually a?ected by the patchy environment, oncethe food in their patch is exhausted or there are abundant natural enemies intheir patch, they will leave in search for new habitats or refuges, at the sametime, the predator species also will be confined in a isolated patch, when thereis little food to feed on or the last prey is eaten the predators will depart andbecome predator dispersers.
