摘要：

On the basis of electronic specific heat, magnetic susceptibility and STS data in La214, we report that a pseudogap of almost the same scale as the low-T (T<<T-c) gap Delta (o) will develop below T*similar toT(co)=2 Delta (o)/4.3k(B) in La214 as in Bi2212. We also report that over a wide hole doping p range in both systems, T-c almost scales with p Delta (o), and suggest that similar top Delta (o) will function as an effective energy gap in determining T-c.
