中文摘要：

刻画了任意两个内部六：也形都无公共边的2-共振六角系统的一些性质，并且给出了一种构造这种六角系统的方法．证明了：设H是一个任意两个内部六边形都无公共边的六角系统．如果它没有弦（chord），那么H是2-共振的当且仅当H∈R或H是一个冠，或是一个六边形，或是一个Tn．如果它有弦，则H可由构造程序生成．

英文摘要：

To characterize some properties of these 2-resonant hexagonal systems in which any two interior hexagons have no common edge, and offer a kind of method to construct this kind of hexagonal system. Then proving the following result： Let H be a hexagonal system in which any two interior hexagons have no common edge. If it has no chord, then H is 2-resonant if and only if H∈R or H is a crown, or a hexagon or a %. If it has chord , then H can be produced by the constructing procedure.
