To resolve the slump - loss of the concrete adding superplasticizers and get better performance , a new superplasticizer , polyaminobenzenesuflate ( hp ) was developed 以主导官能团理论为基础，探讨了高效减水剂的组成与性能之间的关系。
In addition , a kind of perylene derivative with pyridine group was synthesized , which made preparation for self - assemble of perylene mutilayers on silicon 文论文还合成了带有吡啶官能团的?类化合物，为?在硅基上自组装成膜做了前期的研究。
Use lactose as the raw material , the ( s ) - 3 - hydroxybutyrolactone was obtained through reaction steps of decomposition , esterification , protection of function group , acidification 摘要以乳糖为原料以分解酯化、官能团保护、酸化制得目标化合物。
More and more analytical chemists tried to combine the tpp with other functional molecules to obtain the analytical reagents with high sensitivity 把取代四苯基卟啉与其它官能团分子相连以获得对某些物质具有更高灵敏度的检测试剂越来越引起分析科学家的兴趣。
" hydrolysis ： chemical reaction in which water ( h2o or hoh ) and another reactant exchange functional groups to form two products , one containing the h and the other the oh . 水解:一种化学反应，其中水与另一个反应物交换官能团而形成两个产物，一个含h ，另一个含oh 。
We provide a brief survey of recent results on the electronic transport characteristics of single molecules as well as self - assembled monolayers ( sam ) 摘要介绍了测量单个有机分子导电性质的一些进展，包括分子的尺寸效应、官能团效应、分子与电极的接触效应等，以及分子逻辑器件的初步研究。
The chemical function groups in the wood surface are mainly the hydroxide groups with strong polarity and the groups in the plastics are the alkyl groups with non - polarity 由于木材与塑料表面分子结构相差较大，木材表面的主要化学官能团为强极性的羟基基团，而塑料表面则主要为非极性烃基。
Especially , the mesoporous materials with functionalization and various morphologies have been developed in order to obtain higher selectivity and special action sites in past decades 尤其是官能团衍生化或不同形貌特征的介孔材料具有较高的吸附选择性和活性作用位点，更加拓宽了其应用前景。
The results showed that the improvement of surface hydrophilicity did not improve the cell adhesion and cell proliferation effectively , but had great influence on the cell spreading properties 材料表面亲水性官能团的引入没有明显提高细胞的粘附率和增殖率，但却对细胞的铺展性能有重要影响。
More and more analytical chemists tried to combine the 5 , 10 , 15 , 20 - tetraphenylporphyrin ( tpp ) with other functional molecules to obtain the analytical reagents with high sensitivity 把取代四苯基卟啉与其它官能团分子相连以获得对某些物质具有更高灵敏度的检测试剂越来越引起分析科学家的兴趣。
