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。
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.
在实际地震作用下钢筋混凝土结构的反应常常呈现明显的空间效应:框架边柱或角柱中变化的轴力和双向弯曲存在复杂的耦合作用。
The reinforced concrete has an obvious steric effect in real earthquakes. There is a complicated coupling between the axis force and compound bending which change in side columns and angle posts.
