Abstract：
We describe a fitting method of the Z ⁰line shape, discuss the radiative corrections for calculating the theoretical cross sections of e ⁺e ^-→ ff at Z ⁰resonance, and compare the results from different programs. The systematic errors are taken into account in our fitting. As an example, Z ⁰line shape is fitted to determine some Z ⁰parameters by using the τ ⁺τ ^-(γ) channel data.
