ABSTRACT: The matching energy of graph G is defined as , where 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.
