The behavior of neutral weak currents at high energies is analyzed within the framework of the SU(2) -quark vector-like model of weak interactions with a SU(2) x U(1) gauge scheme. The model predicts a substantial threshold variation of both sigmanu-bar/sub neutr//E /sub nu-bar/ and R /sub nu-bar/ =sigma (nu-barN..-->..nu-barX)/sigma (nu-barN..--> mu../sup +/X); this threshold variation is due to the production of heavy t and b quarks.
