摘要

The pressure dependence of the superconductivity of the Tl-Ba-Ca-Cu-O sample with T c >110 K was studied. It is observed that the superconducting transition temperature increases at the rate of d T co / d P≈1.83 K/GPa up to 1.8K/GPa and the gentle steps of T c are always followed by a jump of the normal state resistance which is considered exhibiting the change of some fine structure related to the Cu-O planes.
