Summary

ON THE BASIS OF THE KINEMATIC MECHANISM FOR THE HTSC-CUPRATE HUBBARD MODEL WITH INFINITE INTRAATOMIC REPULSION OF ELECTRONS, THE INFLUENCE OF CUO(2)-LAYER DEFORMATION ON CRITICAL TEMPERATURE VALUES HAS BEEN CALCULATED. IT IS FOUND THAT WITH REALISTIC VALUES OF THE ORTHORHOMBIC DISTORTIONS OF THE CRYSTAL LATTICE, A TENS% RISE OF CRITICAL TEMPERATURE IS POSSIBL THIS IS IN QUALITATIVE AGREEMENT WITH THE DISCUSSED EXPERIMENTS ON YBA(2)CU(3)O(7-Y), LA(1-X)BA(X)CUO(4-Y), BA(2-X)SR(X)CUO(4-Y).
