Abstract：
In this paper we have discussed the ratios between the cross sections of muon-production of J/ψ particles with models explaining the EMC effect in order to investigate the distribution function of gluon in bound nucleon. Comparing the calculated results with the relevant experimental data of EMC group in the small x region, we show that none of these models can explain the ratio satisfactorily. We have analysized the plausible reason s and furnished it with our conjectures.
