摘要: 在核吸收与随动者吸收理论的基础上， 给出了在有QGP相变情况下高能重离子碰撞中的J/Ψ微分产生截面，并用其讨论了CERN的NA50合作组给出的入射动量为158 AGeV/c 的Pb-Pb碰撞中的J/Ψ反常抑制现象。理论较好地解释了实验结果。On the basis of nuclear and comover absorption theories， we have derived out the differential cross section of J/Ψ production in high-energy heavy-ion collisions under the situation that QGP phase transition occurs， and analyzed the experimental data of NA50 Collaboration at CERN in Pb-Pb collisions at 158 AGeV/c. Our theory favors the data well.
