摘要：

High pressure X-ray diffraction studies and electrical resistivity measurements have been performed on high T//c superconductor YBa//2Cu//3O//7 up to 110 kbar at room temperature. X-ray results indicate an orthorhombic to tetragonal phase transition above 70 kbar. The transition is reversible. Electrical measurements also show a decrease in resistivity up to 70 kbar and then an increase.
