We present the structural analysis of single peptide molecules,folding structures of the amyloid peptides,interaction modes between peptide and dye or drug
本论文考察了在活性白土为催化剂的条件下,烷基苯与四种不同二元醇(乙二醇、丙二醇、丁二醇、一缩二乙二醇)之间的烷基化反应,发现在现有烷基化反应条件下,烷基苯与乙二醇、丙二醇
权证一直被许多投资者视为高风险产品,以至于初涉股市都对其退避三舍。事实上,如果能把握好几个关键要素,权证投资的风险将会大幅降低,且收益不一定比股票差。笔者通过将自身在权证市场搏杀多年的经验,以江铜权证为例讲述攻克权证的4大秘籍。 选择有套利空间的权证 自从2005年股权分恩改革以来,沪深股市所发行的权证可分为两类,一类为认沽权证,另一类为认购权证。认沽权证就是看跌期权,在行权日(即权证
