Abstract：
In the frame of color-octet mechanism and according to NRQCD factorization of q production,using three sets of parton distribution function of Pomeron given by L.ALvero et al.,the cross section of J/ψ in γ+p→p+J/ψ+X process is calculated and discussed with the s =200GeV,4GeVT<10GeV. Our results show that the NRQCD matrix elements had a great influence on cross sections,but a little influence on the ratio of diffractive cross section to inclusive cross section. If the influence is eliminated,the ratio is only related to the flux factor and parton distribution functions of Pomeron.
