摘要：
The correlation between the charge-order wave vector Q (CD) and second-neighbor hopping t (') in cuprate superconductors is studied based on the t- t (')- J model. It is shown that the magnitude of the charge-order wave vector Q (CD) increases with the increase of t ('), and then the experimentally observed differences of the magnitudes of the charge-order wave vector Q (CD) among the different families of cuprate superconductors at the same doping concentration can be attributed to the different values of t (').
