在本文中，我们考虑哑铃状度量图上的周期性薛定谔算子，该图是由线和环组成的周期图。设一根线、两环为基本周期。我们看到图的结构和带隙谱之间的关系。
In this paper, we consider periodic Schrodinger operators on the dumbbell-like metric graph, which is a periodic graph consisting of lines and rings. Let one line and two rings be in the basic period. We see the relationship between the structure of graph and the band-gap spectrum.
