论文摘要
通常，通过计算可访问的微晶格的数量或在更一般的情况下，通过使用Gibbs公式来计算平衡中隔离系统的熵。在不可逆的过程中，熵自发增加，这是从统计论证中理解的。我们根据过程的不可逆性水平提出了一种新的熵度量。该公式与通常的计算熵的方法在第一个近似中一致，并且在半经典制度中的黑洞中很容易应用。
Typically, the entropy of an isolated system in equilibrium is calculated by counting the number of accessible microstates, or in more general cases by using the Gibbs formula. In irreversible processes entropy spontaneously increases and this is understood from statistical arguments. We propose a new measure of entropy based on the level of irreversibility of a process. This formulation agrees in first approximation with the usual methods of calculating entropy and can be readily applied in the case of a black hole in the semiclassical regime.
