在存在多个视界的情况下，通常把这些物理量看作是独立的物理量。比较Schwarzschild-de Sitter时空的事件视界和宇宙视界的第一定律，发现它们具有相同的质量、电荷和宇宙常数，这可能意味着两个视界之间存在纠缠。自然地，我们试图增加一个额外的项，它对黑洞的总熵有贡献。我们重新计算的总熵和有效比热，采用整体有效的第一定律，并发现他们将是发散时，两个视界彼此接近。
The thermodynamical quantities are usually considered as the independent ones in the case of the existence of multi-horizons. Comparing the first laws for the event horizon and cosmological horizon of Schwarzschild-de Sitter space-time, we find them share the same values of mass, charge and cosmological constant, which might imply that there exists entanglement between the two horizons. Naturally we attempt to add an extra term, which contributed to the total entropy of the black hole. We recalculate the total entropy and the effective specific heat by taking the globally effective first law and find that they will be emanative when the two horizons approach to each other.
