銅器銘文中有「□□」一詞，與□有關之語詞尚有「□裘」、「□夙夕」，然衡諸歷來學者之說，皆未能對「□」字的三種用例有圓滿的說明。本文試由□字所从之□本當从舟聲，早期時復有近於貉之讀音，並據〈陳侯因□敦〉銘文，對□字的相關語詞進行討論，主要集中於「□□」。認為「□□」當讀為「承紹」，「承」、「紹」皆有紹繼之意。文中並對〈牆盤〉之「□寧天子」提出補充意見。

Cheng Shao (□□) is a set phrase in the inscriptions on bronze vessels in the Western Zhou. Although □ is not preserved in lexicon, □ is preserved in ”Shuo Wen Jie Zi” (《說文解字》). There are two traditional viewpoints about the pronunciation of □, one pronounces it as Zhou (舟), the other as he (貉). In this study, according to □□, the inscriptions on Chen Hou In Qi Dui (〈陳侯因□敦〉), pronunciation of □□ could be Cheng Shao (承紹). Both Cheng (□) and Shao (□) means to inherit in the set phrase.
