Detecting Extended Technicolor Effects via the Process at High Energy e+e- Linear Collider*

We calculate the corrections of extended technicolor (ETC) interactions to the asymmetry parameter and the polarized parameters , of the process in topcolor-assisted multiscale technicolor model. Our results show that the ETC effect on is negligibly small which can be safely ignored, and the ETC effect on may be testable at high energy linear collider (LC). For , , the relative correction of is in the range of , which will certainly be detected at the LC experiments (for example TESLA).
