Abstract：
The ratios of strange baryon to antibaryon produced in the reaction S+ Pb at 200 AGeV beam energy are computed using new version of Fritiof with collective string interaction and rescattering.Theoretical ratios of and are comparable with experimental data within the range of the deviation among the data of different collaborations.It seems to indicate that these data of the ratios of strange baryon to antibaryon might be explained in the hadronic scenario.
