The results show that the condensation degree of dissolved lignin is relative higher and the increase of conjugated double bond is mainly proceeded at the early stage of cooking.
结果表明，溶出木质素的缩聚程度较高，其共轭双键的增加主要发生在蒸煮前期。
C_(60) is one kind of fullerene with high conjugated cage-types structure. Its covalence between two hexagons has high reactivity, which behaves as addition reaction of double bond.
是高度共轭的笼状结构的碳素体，分子结构中六边形环间的共价碳碳双键是富电子区，反应性能与烯烃有类似性，主要表现为双键加成。
