摘      要：The data of charmonium/bottonium suppression in p-A collisions at 800GeV/N are analyzed by considering the shadowing effect of the gluon structure func-tion at small x and the absorption in the target *** empirical parametrization ofthe shadowing effect of the gluon structure function is *** A-and x2-depen-dence of the suppression in p-A collisions is well described based on above physical con-siderations.
