英文摘要	Starting from a separable pairing force of finite range of nucleons, a new set of the pairing strengths for the 1S0 hyperon-hyperon pairing based on the quark model is proposed and the 1S0 hyperon superfluidity in neutron stars with the new hyperon pairing strengths is investigated. The reliable AA pairing strength is 2/3 times NN pairing strength. The upper limit of EE pairing strength is 2/3 times NN pairing strength. The lower limit of the ratio of EE pairing strength to NN pairing strength is 1. With these pairing strengths, the maximum AA pairing gap is several tenths of a MeV which can be compared with the results calculated with the widely used pairing force ESC00; because of a low fraction of E- hyperon, the E superfluidity is very weak or even absent in neutron stars; the E superfluidity is stronger than the results calculated with ESC08c and the pai ring may potentially affect the cooling properties of massive neutron stars.
