RESULTS The water extractive and cos tunolide could inhibit intestine peristalsis of the mice; each team had an obvious cholagogic effect compared with control team and alcohol extractive was stronger than water extractive, costunolide and dehydrocostuslactone were very strong in cholagogic and could be regarded as the main cholagogic constituents.

结果 ig给木香水提物 1.4 g/kg，4.2 g/kg）和木香烃内酯（9 mg/kg，27 mg/kg）对小白鼠的肠蠕动具有抑制作用；熊去氧胆酸（100 mg/kg ）、木香水提物组（540 mg/kg）、木香醇提物组（480 mg/kg）、木香烃内酯组（100 mg/k g）、去氢木香内酯组（100 mg/kg）与对照组相比，各组均有明显的利胆作用，且醇提物要比水提物作用强，木香烃内酯、去氢木香内酯利胆作用很强，可视为木香中的主要利胆成分。

The fact that wastewater has higher chromaticity removal efficiency in acid medium than in basic medium indicates that H+ ions play an important role in chromaticity removal ,possibly by a mechanism of deoxidation in which H+ ionsreact with the organic compound of pollutants in wastewater and cause the chain rupture of chromophoric or anxochromic groups from the organic compound molecules.

Its very difficult to support metal on the surface of crude CNTs. Compared with Pt/C,Pt/CNTs have higher performances in term of efficiency and selectivity. It can be concluded that the interaction between metal and CNTs favors both the high activity and selectivity in cinnamaldehyde hydrogenation.

Pt/CNTs在选择性肉桂醛的选择性加氢中表现出很高的加氢活性和选择性，这是由于纳米碳管外表面独特的结构以及纳米碳管和金属之间相互作用的结果。

CuRF coupounds are based on the combination of deprotonation and ICT mechanisms. The secondary amines conjugated to 1,8-naphthalimide could be deprotonated by Cu2+, and as a result, large red shifts in both absorption and fluorescence spectra were obtained, from which one could sense Cu2+ colorimetrically and ratiometrically.

CuRF 系列则是基于脱氢和ICT原理的结合，铜离子与受体的作用能够诱使共轭氮原子上的氢脱去，共轭氮原子显负电增强了对荧光团的供电能力，从而引起荧光波长的红移，同时也造成了吸收光谱的红移。

As hydrogen atoms and catalyst atoms are normally found bound together as molecules or are bound in other compositions of matter, BlackLight has invented a solid fuel that uses conventional chemical reactions to generate the catalyst and atomic hydrogen at high reactant densities that in turn controllably achieves very high power densities.

通过分离出该进程中的能量产物，用外界元素中电解水。使用水作为燃料，不可见光发电机的可用成本是不昂贵的，而且，他不会带来空气污染或者放射性废物，还具有商业使用价值的氢成分作为氢产物。

苯选择加氢制环己烯具有原子经济性和环境友好等特点，开展苯选择加氢制环己烯催化剂的研究具有重要的应用价值和一定的学术意义。

The results of catalytic activity show that both Ni-B and Ni-P sample have the same kinetic equation for hydrogenation of 1, 3-cyclopentadiene to cyclopentene and the same TOF. Therefore, it can be suggested that they have the similar active site. The catalytic activity of Ni-B sample is higher than that of Ni-P sample, and it is due to the more active sites of Ni-B sample having.

催化活性测试表明，Ni-B与Ni-P催化环戊二烯加氢反应对环戊二烯具有相同的动力学方程，而且两者具有相似的氢转换频率，表明两者的活性中心本质上是相似的，类金属不同导致的电子转移方向的不同仅仅影响反应的初活性，宏观活性的差别在于两者活性中心数量的不同。
