摘要：
A correlation of the distance Cu(2)-Cu(2) with dT(c)/dP is established for YBa2Cu4O8 and YBa2Cu3O66. This model yields dT(c)/dP = 5.07 K GPa-1 for YBa2Cu4O8 and dT(c)/dP = 4.65 K GPa-1 for YBa2Cu3O6.6, both of which are in excellent agreement with the experimental data. It is also found that YBa2Cu3O6.6 has similar pressure-induced structural changes as YBa2Cu4O8, but different from YBa2Cu3O6.93.
