英文摘要	The join of two disjoint graphs G and H, denoted by G boolean OR H, is the graph obtained by joining each vertex of G to each vertex of H. In this paper, the signless Laplacian characteristic polynomial of the join of two graphs is first formulated. And then, a lower bound for the ith largest signless Laplacian eigenvalue of a graph is given. Finally, it is proved that G boolean OR K-m, where G is an (n - 2)-regular graph on n vertices, and (K) over barn boolean OR K-2 except for n = 3, are determined by their signless Laplacian spectra.
