Abstract：
We state a fitting method of the Z⁰ line shape.We discuss the radiative corrections for calculating the theoretical cross sections of e⁺e^－→ff on Z⁰ resonance,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 Z⁰ line shape to determine some Z⁰ parameters.
