摘要：

We revisit the constraints on the deep lunar interior with a possible low-viscosity zone at the core mantle boundary obtained from our previous forward modeling of the tidal response of the Moon, by comparing a numerical model with several tidal parameters (i.e., k(2), k(3), h(2), and Q) that have been improved or are newly determined by recent geodetic observations and analyses from GRAIL (gravity), LRO (shape), and LLR (rotation). Our results are in principle consistent with these data and suggest a low viscosity layer (with an outer radius of about 540-560 km) which possibly extends inside the region where deep moonquakes occur.
