Abstract：
We describe a fitting method of the Z⁰ line shape, discuss the radiative corrections for calculating the theoretical cross sections of e⁺e^- → ff at Z⁰ resonance, and compare the results from different programs. The systematic errors are taken into account in our fitting. As an example, Z⁰ line shape is fitted to determine some Z⁰ parameters by using the τ⁺τ^- (γ) channel data.
