酰胺化

Thirdly,in the view of some different results between the reaction of complexes(2)、(3)and[(Me_3Si)_2N]_3LnLi_3 with aromatic aldehydes, the reaction of 2 equiv of aromatic aldehydes with 1 equiv of lithium amide(1) catalyzed by the YCl_3 was subsequently studied,and better yields of the corresponding amides and alcohols can be isolated.These results indicated that the enolate ligand in complexes(2)、(3)may have impact on the Cannizzaro disproportionation reaction.

第三，鉴于上述配合物2、3和[(Me_3Si_2)2_N]_3LnLi_3与芳香醛反应结果上的一些差别，我们又以三氯化钇为催化剂，将两当量的芳香醛与一当量化合物1的锂盐直接进行反应，结果以较好的产率得到了相应的酰胺和醇，这说明配合物2、3中所含的乙烯醇基可能对此Cannizzaro-型歧化反应存在一定的影响。

In this paper,the Lactate dehydrogenase, malate dehydrogenase,superoxide dis-mutase of five tissues of Carassius auratus gibelio; Cyprinus carpio Linnaeus; Esox americanus Gmelin; Leuciscus waleckii in Dalai Lake were studied by vertical polypropylene gel electrophoresis and the isozyme composion of four kinds of fishes were obtained. Then the analysis of the expressing specify of 3 kinds of isozyme in different tissues and loci were carried on and the genetic base of isozyme system was discussed.

本实验采用垂直板聚丙烯酰胺凝胶的电泳方法对达赉湖的野生鲤鱼、银鲫、狗鱼、东北雅罗鱼的五种组织脏器(肌肉、心脏、肝脏、脑、眼睛)的三种同工酶(苹果酸脱氢酶、乳酸脱氢酶、超氧化物岐化酶)进行了初步研究，获得了达赉湖四种鱼类物种的同工酶谱，在此基础上对同工酶在不同组织的表达差异和基因位点进行分析，探讨其同工酶系统的遗传基础。

Eamamined by fluorescin staining and Giemsa staining, 0.2 mg/L colcemid was considered suitable for inducing high percentage of micronuclei in A9 (neo12) cells, without causing death of a mass of cells.

通过荧光染色和吉姆萨染色分析，结果表明，A9(neo12)细胞经0.2 mg/L秋水仙素酰胺处理48 h后，89﹪的细胞产生微核化，每个细胞平均形成10个微核。

In this dissertation, the sodium bentonite was modified using hexadecyl trimenthyl ammonium bromide and cationic polyacrylamide.

The sodium bentonite was modified by organic reagent hexadecyl trimenthyl ammonium bromide and cationic polyacrylamide. The structures of modified organo-bentonite and the effect of concentration of the intercalating reagent and reacting time on decoloring capacity were studied.

用阳离子有机改性剂十六烷基三甲基溴化铵和阳离子聚丙烯酰胺复合插层改性钠基膨润土，分析了改性膨润土的结构，研究了改性剂质量浓度及二次改性时间对复合插层膨润土脱色效果的影响。

The amphiphiles, 4-8, can not form reverse bilayers in organic solvent, which result in that the molecular interactions unable to meet the need for hydrophile-lypophile balance, so that they crystallize and exhibit no gelling abilities. The mono-chained L-alanine derivatives, 1-3, can self-assemble into bilayer aggregates, through intermolecular hydrogen bonding and homochiral effect in a number of organic liquids, which are juxtaposed and interlocked by van der Waals interaction, and finally gelate the organic liquids.

单链酰基化L-丙胺酸两亲物1-3在一些低极性的有机溶剂可以通过分子间氢键相互作用及同手性聚集作用形成有序的反双分子膜结构，这些有序反双分子膜结构单元依靠vander Waals力相互作用可以平行排列且相互之间进行连结形成长纤维状的聚集体，纤维状聚集体在有机介质中可以进一步相互连结形成三维网状结构，进而胶凝有机溶剂。

In mice for 3 days to make immunity hypofunction mice model and given selenocarrageenan syrupus by gastric gavage for 30 days.

小鼠腹腔注射80mg/kg环磷酰胺诱导免疫抑制小鼠模型；硒化卡拉胶口服液连续灌胃30d，每天1次。

And TM was carefully added to the solution of photo-PAE to form a PSPI solution containing TM. The composite filmcast from PSPI-TM can be developed using NMP. When the content of Ti〓 incomposite film was beyond 3%, a heateddeveloper had to be used for the successful development of the composite film.Compared with corresponding ester-type PSPI, D〓 of PSPI-TM increasedrapidly with the content of TM in the composite.

光刻实验发现这种含TM的PSPI光刻胶膜比相应的酯型PSPI光刻胶膜难显影，一般需NMP这样的强溶解性能的溶剂作为显影液，才能顺利显影，当Ti〓含量大于3％(基于酰亚胺化后PI的量)，必须升高温度才能顺利显影；这种含 Ti的PSPI光刻胶在感光性能上也比相应的酯型PSPI光刻胶低很多倍，形成50％留膜率所需的曝光剂量随TM含量的增加，而大幅度地增加。
