本文考虑一般静态时空中的准定域能。我们遵循作者在[19，20，7，9]中开发的方法，并将准局部能量定义为表面哈密顿量的差，该表面哈密顿量源自Einstein-Hilbert作用量。新的准定域能量提供了一个有效的独立于规范的测量，可以测量时空在一个扩展的区域上偏离参考静态时空的距离。
This article considers the quasi-local energy in reference to a general static spacetime. We follow the approach developed by the authors in [19, 20, 7, 9] and define the quasi-local energy as a difference of surface Hamiltonians, which are derived from the Einstein-Hilbert action. The new quasi-local energy provides an effective gauge independent measurement of how far a spacetime deviates away from the reference static spacetime on a finitely extended region.
