计算一些块循环图的距离谱和距离能量.在此基础上,给出一个从一组距离正则的非同谱等能量图构造任意多组距离正则的非同谱等能量图的方法.
The distance spectra and distance energies of some block circulant graphs were given. Based on these results, a method for constructing an arbitrary number of groups of distance regular noncospectral equienergetic graphs from a group of distance regular noncospectral equienergetic graphs was given.
