側鏈基團 的英文怎麼說
中文拼音 [zhāiliànjītuán]
側鏈基團
英文
side-chain radical-
Bc asphaltenes similar to petroleum asphaltenes and consist of aromatic nuclei, aliphatic chains, and naphthenic ring structures combined in three - dimensional network. but black carbon asphaltenes contains more aromatic carbon, oxygen - function groups, and less aliphatic chains
但碳黑瀝青質與原油瀝青質也是不同的，碳黑瀝青質的分子結構中含有更多的芳香結構組分和含氧基團，較少的脂肪側鏈組分。A kind of novel pu and poly ( acrylate - co - methyl methacrylate ) s with nonlinear optical conjugated group were synthesized. their properties were studied. the main contents of this dissertation consist of the following points : 1
本論文合成了一類含非線性生色團的長側鏈的聚氨酯和一類聚丙烯酸酯及其與甲基丙烯酸甲酯的共聚物，並對它們的非線性光學性能進行了研究。And some methods for improving their poor solubility are introduced, including : incorporating bulky groups, hydrophilic groups, water soluble polymers and hyper - branched dendrimers ; synthesizing branched derivatives ; and degrading them into oligosaccharide
對其解決的方法進行了分析總結：將體積較大的側基或親水性基團大分子引入到分子鏈上，支鏈化或鍵接超支化合物，以及低聚糖化，以滿足不同應用領域特別是生物醫學工程的要求。So it has been found that this polymorphism of sod was changed under different experimental conditions, which showed that the polymorphism was not caused by the difference of genes or the difference of length or side groups of the peptide chains which was caused during the processing after transcript or the purification
由此排除了其是由不同基因編碼的同工酶或在轉錄后加工及分離純化過程中形成肽鏈長短不一和酶分子側鏈基團差異等微不均一性所造成的可能性。Side chain polyurethanes with azo group are characterized and confirmed by ftir, uv - vis, dsc, vpo, z - scan, polarize microscope. the results show that the end - group and the flexibility of main chain affects the growing up of liquid crystalline phase greatly. because the determinable way of detection is defective, it was not founded the liquid crystalline behavior obviously contributes to the non1inear optical thection
最後，在分析討論實驗結果的基礎上，指出側鏈型聚氨酯液晶中側鏈介晶基元的末端基團及主鏈的柔性對其液晶態的形成有重要影響；由於檢測手段的不齊備，未能觀察到熔致型聚氨酯液晶的液晶行為對其非線性光學效應的貢獻作用。分享友人
