论文摘要
由于在吉本斯（Gibbons）上的静态第一定律中，由于静态贴片的静态贴片，宇宙学范围的熵通过添加杀伤能量减少了。这个负迹象提出了一个令人困惑的问题，该如何应如何理解静态斑块的热力学。我们认为这种混乱之所以出现，是因为对物质的错误解释错误地将能量杀死了总体能量，并通过引入可以指定适当热力学集合的系统边界来解决难题。当这个边界缩小到零时，合奏的总内能（棕色能量）随之而来，其变化也消失了。这种消失的变化的一部分被热效，由地平线熵变化捕获，部分是物质的贡献，可能会或可能不会被热化。如果此问题处于DE Sitter温度下的全球均衡状态，则第一定律将成为广义熵是静止的陈述。
Due to a well-known, but curious, minus sign in the Gibbons-Hawking first law for the static patch of de Sitter space, the entropy of the cosmological horizon is reduced by the addition of Killing energy. This minus sign raises the puzzling question how the thermodynamics of the static patch should be understood. We argue the confusion arises because of a mistaken interpretation of the matter Killing energy as the total internal energy, and resolve the puzzle by introducing a system boundary at which a proper thermodynamic ensemble can be specified. When this boundary shrinks to zero size the total internal energy of the ensemble (the Brown-York energy) vanishes, as does its variation. Part of this vanishing variation is thermalized, captured by the horizon entropy variation, and part is the matter contribution, which may or may not be thermalized. If the matter is in global equilibrium at the de Sitter temperature, the first law becomes the statement that the generalized entropy is stationary.
