摘要：

We present a detailed description of the method and results of our calculation of the kaon B parameter using the Wilson quark action in quenched QCD at beta = 5.9-6.5. The mixing problem of the Delta s = 2 four-quark operators is solved non-perturbatively with full use of chiral Ward identities. We find B-K(NDR, 2GeV) = 0.562(64) in the continuum limit, which agrees with the value obtained with the Kogut-Susskind quark action.
