程瑶田的学术,学界过去比较关注他精于名物制度的一面,认为其特点在于运用金石考古、文字训诂等方法进行客观考证,对其丧服学的理解也多从此出发。本文将作如下辨析:程瑶田的丧服学代表了他学术中容易被忽视的另一面。所著《仪礼丧服文足徵记》在郑玄经注之外建立起独具特色的丧服学体系,具体方法是阐发经文条例和写作手法,在条例之间建立起严密的逻辑联系,不惜为此调整、改变礼义概念的基本内涵,以实现《丧服》经传文字的完备无误。因此,《足徵记》的实质是脱字实际礼义舆礼制的理论体系。 Cheng Yaotian’s academic and academic circles in the past paid more attention to his dedication to the celebrity system. He believed that his characteristic was the objective textual research on the use of archeological and scriptural methods, and his understanding of his funeralism. This article will make the following analysis: Cheng Yao Tian mourning school represents the other side of his academic easily overlooked.

The specific method is to elaborate scriptural rules and writing techniques and establish close logical connection between the regulations.

Therefore, the essence of “foot sign” is the theoretical system of taking off the word of ritual and courtesy.
