Electron-impact excitation collision strength W (nl-n抣?/I>)，(3≤n≤7，4≤n?/FONT>≤7) among configuration average levels for the Cu-like Ions Ba,Nd,Gd,Yb,Au,Pb have been calculated systematically using the quasirelativistic distorted-wave methods. In addition, the collision strength in high energy limit have been calculated. The data for the collision strength or thermally averaged rate coefficient over the entire range of energy or temperature have been evaluated by a least-squares spline fitting procedure. As a result, the collision strength with arbitrary electron energy and rate coefficient with arbitrary temperature can be determined by ten parameters. Some scaled rules have also been given in the paper.
