摘      要：A graph G is said to be determined by its Laplacian spectrum if any graph having the same Laplacian spectrum as G is isomorphic to *** consider θ-graphs,that is,graphs obtained by subdividing the edges of the multigraph consist of three parallel *** this paper,some special θ-graphs are determined by their Laplacian spectra.
