摘要：

Based on the temperature dependence of two-local-spin-mediated interaction for Br2Sr2CaCu2O8+delta (B2212), this paper explains the fourteen features of the pseudogap (PG) in underdoped B2212, and makes three predictions. The most unusual prediction is the existence of a 61 meV PG at 300 K in the range of T-c = 0 for underdoped B2212.
