The matching energy of graph G? is defined as src="Edit_c813092e-5496-4b76-9eee-731b0ae3c6b7.bmp" width="123" height="25" alt="" />?, where src="Edit_8228c467-066d-4018-a80e-d9e12fd3d2d9.bmp" width="115" height="25" alt="" />?be the roots of matching polynomial of graph G. In order to compare the energies of a pair of graphs, Gutman and Wager further put forward the concept of quasi-order relation. In this paper, we determine the quasiorder relation on the matching energy for circum graph with one chord.
