摘要：

The heavy-top-quark contribution to electroweak radiative corrections is studied through the M(W)-M(Z) relation in the framework of the standard SU(2) x U(1) theory. The latest data on the W- and Z-boson masses seem to indicate, though still at the 1-sigma level, that the nondecoupling terms proportional to m(t)2 or ln m(t), which are a characteristic feature of theories with masses generated by spontaneous symmetry breakdown plus large Yukawa couplings, have to exist whatever value the Higgs-boson mass takes.
