摘要：
The D-eigenvalues of a connected graph G are the eigen-values of its distance matrix D, and form the D-spectrum of G. The D-energy E-D(G) of the graph G is the sum of the absolute values of its D-eigenvalues. Two (connected) graphs are said to be D-equienergetic if they have equal D-energies. The D-spectra of some graphs and their D-energies are calculated. A pair of D-equienergetic bipartite graphs on 24t, t >= 3, vertices is constructed.
