Correlation between superconducting T~ and hole concentration was investigated in the Bi2Sr2CaCu208+~ system. The hole concentration was varied by substituting cations with different valences for Sr or Ca. In order to increase the hole concentration, some samples were annealed at 430°C in 250 bar of
