Abstract：
We analyse the data of charmonium/bottonium suppression in P-A processes by considering the gluon shadowing effect at small x and the final-state interactions in the target nucleus. An empirical parametrization of the shadowing effect of the gluon structure function is used. The A- and x2-dependence of the suppression in P-A collisions is well obtained based on above physical consideration.
