摘要：
Within the t-J model Hamiltonian we present a resonating valence-bond mean-field theory directly in terms of dopant particles. We apply this theory to NaxCoO2 center dot yH(2)0 and show that the resulting phase diagram T-c versus doping is in qualitative agreement with the experimental results.
