气体水合物是一类笼形结构的冰状晶体。
气体水合物是一类笼形结构的冰状晶体。
基弗尔说：“通过南极与造山运动相关联的地震，气体被从笼形结构中释放出来。”
Gas is released from the clathrates by the earthquakes associated with the tectonic activity at the South Pole.
笼形结构——能够捕获气体的象冰一样的晶格结构的存在，可以很容易地解释我们在这颗卫星上看到的现象。
The presence of clathrates, ice-like lattice structures that can trap gases, could just as easily explain what we see on the moon.
一个是气体水合物，这是一种白色的、类似果汁冰糕的混合物，通常由嵌入笼形水结构的甲烷组成。
One is gas hydrates—white, sorbet-like compounds that usually consist of methane molecules trapped in a cage of water.

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.
