Results: It was observed that projections from IN to hypothalamus passed through the superior cerebellar peduncle, crossed in its decussation and then many of them entered posterior hypothalamic area by iontophoresis of Dextran-Texas Red to cerebellar IN. Using the methods of iontophoresis of Fluoro-Ruby and double labelling staining, it was also observed that the neurons projecting to PH in cerebellar IN were glutamatergic neurons.

结果：小脑间位核电泳Dextran-TR后示踪可见间位核神经元发出离核纤维，行走于同侧小脑上脚中，在小脑上脚交叉处交叉到对侧，然后继续走行于小脑上脚中，到下丘脑后较多纤维终止于下丘脑后区；在下丘脑后区电泳Fluoro-Ruby后可逆行追踪到小脑间位核神经元，荧光双标法显示投射到下丘脑后区的小脑间位核神经元中有谷氨酸能神经元。

In the first part, one of the side-arms of hexakisbenzene was replaced with a 4-pyridinylethynyl group. Comparing with analogous compounds incorporating a 2- or 3-pyridinylethynyl moiety, the compound with a 4-pyridinyl -ethynyl unit shows lowest melting and clearing points.

The results indicate that thermal stabilities and decomposition mechanisms of the title compounds derived from the BDE, Ea and static electronic parameters are basically consistent. Homolysis of the N—NO2 bond is the initial step in the thermolysis of the title compounds, the meta-isomers are more stable than the para-isomers, and the ortho-isomers are the most sensitive.

结果表明，由BDE、Ea和静态电子结构参数推断的标题物热稳定性和热解机理的结论基本是一致的，N-NO2键均裂是标题物的热解引发步骤，间位取代异构体较对位取代异构体稳定，而邻位取代的异构体稳定性最差。

The yields were better when DHPCE with nitro group in meta or ortho position of the benzene ring were hydrolyzed in basic conditions, while the hydrogenolysis and acidic reactions gave very poor yields.

当苯环的间位和对位存在硝基，碱性水解时，在二氢吡啶环的3位引入氯乙醇的酯能得到较好的收率；酸性水解和氢解法则不宜用来合成ADHPA。

We described that the nitro group is a stronger electron withdrawing and meta activating characters than the imide group, the amino and hydroxy are both electron donating groups and had ortho, para activating characters. The methyl group might have a steric hindrance effect in this reaction. Our results indicated that methyl group at the ortho position of the amino group on the benzene ring, the steric hindrance effect became stronger.

另一方面，由产率上的结果来看，可以得知硝基为强力的拉电子基团，会减少邻位和对位胺基的电子密度比间位多；而氢氧基与胺基是供电子基团，会增加邻位和对位胺基的电子密度比间位多；甲基取代对反应则只有立体障碍的影响，而且与反应的氨基成邻位存在下影响最大。

For a disubstituted complex, MA4B2, the planar arrangement gives three isomers, the familiar ortho, meta, and para arrangement s of organic chemistry.

对于双取代络合物MA4B2，其平面排列有三个异构体，常见的为有机化学中的邻位、间位和对位排列。

In complexes 8～16 synthesized by hydrothermal method, most of the ligands adopt multidentate coordination modes joining several lanthanide ions into high-dimensional coordination polymers. And changing of 5-substituting group on isophthalic acid has a little effect on the coordinated abilities of the meta-carboxyl groups.

水热法制备的配合物8～16中，配体多采取多齿配位模式桥连多个稀土离子，形成高维配位聚合物，同时由于羧基氧原子和稀土离子的强的键合力，间苯二甲酸的5位取代基的变化对间位羧基的配位能力的影响不大。

O-MNT、 p-MNT and m-MNT are got by mononitrating toluene, and the quantity of p-MNT and m-MNT that are needed is increased greatly, there is a great economic benefit to improve their ratioes , so the objective of this study is to improve the ratioes of p-MNT and m-MNT in the mononitration of toluene respectively through changing temperature and mixed acid composition in industrial way.

甲苯一硝化生成邻硝基甲苯、对硝基甲苯、间硝基甲苯，其中对硝基甲苯和间硝基甲苯的用量明显增加，提高它们在产物中比例的研究，具有十分可观的经济价值，所以本文从工业化的角度出发，通过改变温度和硝硫混酸的组成，分别对提高一硝基甲苯中对、间位异构体的比例进行研究。

And the ability of antioxidant of polyhydroxy benzamides don't have too many differences with Trolox (IC50 =13.90 μg/ml), the substition of hydroxy group at amino benzene ring doesn't affect the whole ability of antioxidant apparently, but while the single hydroxy group at carboxylic acid benzene ring, they are apparently decrease to scavenge the ability of free radical, as a result, the hydroxy at amino benzene ring substitutes its function, without the hydroxy group, the ability of antioxidant is worst, but it upgrades its function while the hydroxy and amino are in the ortho-position or para-position.

而当多酚醯胺化合物其抗氧化能力与Trolox差不多时(IC50 =13.90 μg/ml)，胺基苯环上之羟基取代对整体抗氧化能力影响不明显，但在羧酸苯环上具单羟基时，其清除自由基能力明显下降，使得胺基苯环上羟基取代发挥了影响力，无羟基取代时，抗氧化能力最差，而羟基与胺基互为邻位或是对位时较间位有提升效果。
