摘　　要：长期以来,月球幔层底部是否存在一个部分熔融的S波衰减层一直存在着争议.针对这一争议,本文首先回顾了国内外对月幔底部黏弹性结构的研究成果,梳理总结了争议的提出和发展历程,接着分析这一争议产生的主要原因.本文认为,虽然越来越多的研究支持月幔底部存在一个部分熔融的低黏性、低S波波速的转换层,但目前仍缺乏决定性的证据作为支撑.因此,本文进一步讨论了现有研究存在的不足,对未来研究方向进行了展望.The existence of a partially molten S-wave-attenuating layer at the base of the lunar mantle is a topic of long-standing debate.To address this contentious issue,herein,domestic and international studies on the viscoelastic structure of the lunar mantle’s lower region are meticulously reviewed.Furthermore,a comprehensive overview of the origins and historical development of this matter is provided,followed by an in-depth analysis of the crucial factors contributing to the ongoing controversy.While an increasing number of studies lend support to the presence of a partially molten low-viscosity layer that attenuates the S-wave at the base of the lunar mantle,definitive evidence remains lacking.Finally,the limitations of existing studies are discussed,and future research endeavors to be undertaken are provided.
