1) triangularly connected
三角连通
1.
A graph G is triangularly connected if for every pair of edges e1,e2∈E(G),G has a sequence of 3-cycles C1,C2,…,Cl,which meet the condition of e1∈C1,e2∈Cl and E(Ci)∩E(Ci+1)≠(1≤i≤l-1).
对于任意一对边e1,e2∈E(G),在G中存在一系列3-圈C1,C2…,Cl使得e1∈C1,e2∈Cl且E(Ci)∩E(Ci+1)≠Φ(1≤i≤l-1),则称图G为三角连通的。

单连通和多（复）连通超导体（simplyandmultiplyconnectedsuperconductors）
单连通超导体一般指的是不包含有非超导绝缘物质或空腔贯通的整块同质超导体，若有非超导绝缘物质或空腔贯通的超导体则称为多（复）连通超导体。从几何学上讲，在超导体外表面所包围的体积内任取一曲线回路，这回路在超导物质内可收缩到零（或点），且所取的任意回路均可收缩到零而无例外，则称单连通超导体。若有例外，即不能收缩到零，则称多连通超导体。例如空心超导圆柱体，则在围绕柱空腔周围取一回路就不能收缩为零。多连通超导体可有磁通量子化现象（见“磁通量子化”）。
