Abstract：
In this paper the cross section of the production of tc(or tc)by e⁺e^－→(or tc),is computed in the Standard Model and its extension with two Higgs-doublets as well as the fourth generation fermions included.The results show that even for the top mass is so high around 140GeV,as predicted by the Model,the cross section of this process still may be reach at an observable valne at the LEPⅡ if favourable parameters are taken in the extension model.
