摘要
 An edge e of a graph G is said to be a fixed edge if G−e+e′≅G implies that e′=e, and a forced edge if G−e+e′ is an edge-reconstruction of G implies that e′=e. In this paper, we use the method of excludable configurations to investigate the fixed edges and the forced edges of series-parallel networks. It is proved that all series-parallel networks contain fixed edges except P3∨K1 and P4∨K1, and that all series-parallel networks are edge-reconstructible.
