主　　题：quark hadron transition 

摘      要：We investigate the influence of the energy gap(Δ)of the color-flavor locked(CFL)quark phase on the bulk properties of hybrid *** relativistic mean field model is used for hadronic matter and the MIT bag model for CFL quark *** our calculation results,we find that with the increase of the CFL energy gap there exists a transition behavior,which goes from the hadron star range through the transition range into the CFL quark star *** observation data of PRS J1614-2230 are in the hadron star range(withΔ40MeV).We also find that with hyperons the equation of state(EOS)for the hybrid star matter with the CFL quark matter core has a small change,which can be disregarded.
