摘要：

A method for evaluation of the critical temperature T-c and the width of the superconducting transition Delta T-c in HTSC single crystals has been developed. By this method, the first derivative of the temperature dependence of the resistivity, partial derivative rho(T)/partial derivative T, is constructed. A technique for synthesis of YBa2Cu3O7-x single crystals with highly reproducible physical-mechanical properties has been described. A standard sample with T-c = 94 K and Delta T-c = 0.25 K has been synthesized and certified.
