# 有向双圈图的第二小斜能量The Second Minimal Skew Energy of Oriented Bicyclic Digraphs

Abstract: The energy of a graph has closed links to chemistry, since an important quantum-chemical cha-racteristic of a conjugated molecule is its total π-electron energy. In this paper, we compared the characteristic polynomial coefficients of oriented bicyclic graphs and gave the skew energy’s partial relation of oriented bicyclic graphs, and thus we got the second minimal skew energy of oriented bicyclic graphs.
