Abstract：
We state a fitting method of the Z ⁰line shape.We discuss the radiative corrections for calculating the theoretical cross sections of e ⁺e ^－→ff on Z ⁰resonance,and compare the results from different programs.The systematic measurement errors are taken into account in our fitting.As an example,we fit the τ ⁺τ ^－channel Z ⁰line shape to determine some Z ⁰parameters.
