Abstract
A theoretical scheme for describing the quasiparticle-pair superconduc tivity in doped CuO2 system is suggested based on the model put forwar d by Emery and Reiter. The doped O holes and associated two neighborin g Cu-spins form spin-1/2 quasiparticles. Through the magnetic interact ion with the spin background, the quasiparticles interact with each ot her and lead to pair condensation which is responsible for the superco nductivity.
