A new structure assembly method is proposed to describe the high T_c superconductor materials. Using this method, the main crystalline structures of the high T_c superconductors were derived in the language of infinite layer in Cu-O perovskite. Furthermore, a three digit nomenclature has been adopted to catalog the structures of the high T_c superconductors.
