摘要：

The anisotropic stress effects on superconducting temperature T-c have been investigated in single crystals of La2-xSrxCuO4 with x = 0.10 and 0.145. Utilizing non-hydrostaticity of the applied pressure, me estimated T-c in the tetragonal phase at the ambient pressure. The T-c was found to be higher in the tetragonal phase than the T-c in the orthorhombic phase. We demonstrate that, the orthorhombic distortion suppresses superconductivity and the tetragonal structure with the flat CuO2 plane is favorable for superconductivity.
