Abstract：
In this paper the experimental value of radiative correction Δr was derived from the new data of sin ²θ_w and W boson mass M_w given by LEP,CDF and other collaborations.A careful comparison of (Δr)_exp with the standard model expectation was carried out.We first calculated the Δr at full one-loop level,and then the main two-loop contributions were included.More stringent upper bounds on M_t were obtained from the analysis of probability distribution:M_t175GeV at 95%C.L. for a given M_H=100GeV.The effects on N_t from other experimental and theoretical errors were also computed.
