研究结果表明，V_2O_5/C催化剂对乙二醛的氧化具有良好的催化活性和乙醛酸选择性，反应过程中无需控制溶液pH值即可得到乙醛酸，乙醛酸在V_2O_5/C催化剂作用下不存在过度氧化，乙二醛的氧化产物主要是甲酸和乙醛酸，它们是一平行反应。

Eventually such clumsy responses may make countries approach things narrowly and nationalistically, creating more global instability and less peace and prosperity.

最终这些笨拙的反应可能使得各国狭隘地、国家主义地追求一些东西，而引起全球更不稳定、更不和平、更不繁荣。

In chapter 2, the Michael additions of functionalized organozinc iodides with α,β-unsaturated aldhydes, ketenones, esters and l-aryl-2-nitroetheneshave been investigated in the presence of Cu〓/ 2LiCl.

第二章主要研究了在低毒、稳定、易得、价廉的Cu〓存在下，带官能团的有机碘化锌与α，β-不饱和醛、酮、酯及1-硝基-2-芳基乙烯的Michael加成反应，并探讨了反应机理。

It was reported that benzylidenemalononitrile did not react with 1-benzyl-1,4-dihydronicotinamide. However, similar reaction easily takes place under the same condition when the phenyl group is replaced by the pyridyl group.

本课题组之前报道了苯亚甲基丙二腈在室温下不能被BNAH所还原，本论文将反应底物中的苯基换成吡啶基之后，在同样的实验条件下，反应可以比较顺利的进行。

Now,the method of dynamics is used in normal applications by measuring the sulphation degree of the solid calcium oxide to infer the reaction activity of limestone;but it is not enough on condition of many types of impurity the limestone composition,which has considerable influence on the desulphurization reaction activity of limestone.

目前，国内外主要采用动力学方法，通过测定固态CaO的硫酸盐化程度来推断石灰石的反应活性。但是这在石灰石中含有许多其它杂质成分时是不够全面的，因为这些杂质成分对石灰石的脱硫反应活性影响很大，不能忽视。

The chiralMn complexes, especially Jacobsenscatalyst, display high enantioselectivity for asymmetric epoxidation of conjugated cis-di-, tri-and some tetrasubstituted prochiral alkenes in the NaClO biphasic system, but the epoxidationreaction generally requires a long reaction time even in the presence of an axial ligand.

在NaClO两相体系中，手性Mn配合物，尤其是Jacobsen催化剂，对共轭顺式二取代、三取代和部分四取代烯烃的不对称环氧化具有高的对映选择性，然而即使存在轴向配体，环氧化反应也通常需要长的反应时间。

The device not only has high mass transfer efficiency and high utility rate of luminous energy that are possessed by floating photocatalytic reaction devices, but also can retain the hollow glass microsphere filled with titanium dioxide in the reaction area through the quartz sand filtering layer, thereby recycling the photo-catalyst.

本装置既具有悬浮式光催化反应装置所具有的高传质效率和光能利用率，又可以通过石英砂滤层，使负载二氧化钛的空心玻璃珠停留在反应区内而不流失，实现了光催化剂的重复利用。

These enzymatic haemostatic agents can be used to antagonize the side effect of hirudin. We take the batraxobin as an example to illustrate that the enzymatic haemostatic can antagonizes hirudin. Agglutination reaction occurred after the tubes containing hirudin were added with batroxobin , i.e., batroxobin can antagonize hirudin. In a canine model,, the reduction extent of TT and APTT in the test group was larger than that in the control group; the bleeding time was decreased obviously and it was shorter in the experimental group than in the control group at lh, 2h and 3h after hirudin injection, indicating batroxobin can antagonize the bleeding side effects of hirudin.

以巴曲停为例，加入巴曲停的水蛙素抗凝试管内又可发生凝集反应，而未加入巴曲停的试管内不发生凝集反应；犬动物模型显示，水蛙素实验组TT值、 APTT值明显低于水蛙素对照组，犬给予巴曲停后出血时间明显缩短，出血时间在滴注水蛙素后lh、2h、3h明显短于对照组(P.05)，说明巴曲停有拮抗水蛙素抗凝血的作用。

After the failure of achieving good enatioselectivity in asymmetric Baylis-Hillman reaction, we turned our attention to traditional chiral Lewis base catalyzed asymmetric Baylis-Hillman reaction.

我们还发现，用咪唑与-脯氨酸共催化醛和丁烯酮的Baylis-Hillman反应，但产物的e.e值还是很低，因此又回到了传统的用手性Lewis碱催化不对称Baylis-Hillman反应研究中。
