论文摘要
角动量的超级翻译歧义问题是一般相对论的长期问题。最近，在零无穷大的角度动量的第一个定义是超跨性不变的。但是，在紧凑的二元聚结界中，经常忽略超级翻译歧义。本文表明，我们有一个幸福的情况，即新定义的角动量与四极级的经典定义一致。
The supertranslation ambiguity issue of angular momentum is a long-standing problem in general relativity. Recently, there appeared the first definition of angular momentum at null infinity that is supertranslation invariant. However, in the compact binary coalescence community, supertranslation ambiguity is often ignored. This paper demonstrates that we have the happy circumstance that the newly defined angular momentum coincides with the classical definition at the quadrupole level.
