中国汉唐古典舞独特的舞蹈元素和审美风格，使得汉唐古典舞极有可能成为我国舞蹈的典型代表，成为我国舞蹈屹立于世界的“符号性”舞蹈。通过多年的舞蹈学习，笔者深刻地认识到重心乃舞蹈之根基，一种舞蹈风格形成的关键在于它对重心的独特处理。因为重心是维持舞蹈动作平衡的关键，是舞蹈风格把握的关键，对于舞姿形成和动势流动有基础性作用。本文以重心为突破口，来分析孙颖教授创建中国汉唐古典舞的内在逻辑。如果将汉唐古典舞视为一种文化符号的话，那么其重心无疑是构成符号的重要形式因素。通过本文的分析与研究，作者认为以孙颖为核心创建的中国汉唐古典舞的重心有不平均、失重、以及向下抛物线的轨迹的特点，这样的重心特点与我国古代人的审美取向、舞蹈美学思想以及孙颖创建汉唐古典舞系的理念之间有密切关联，具体而言，汉唐古典舞的既定风格与重心间的关系是：风格造就重心，重心成就风格。本文的研究目的在于让舞者和编创者从重心的运动规律来把握汉唐古典舞动作的本质，从而传达出汉唐古典舞的独特风格。希望通过我的分析与研究，让汉唐古典舞的舞者、编导、和教育者对于汉唐古典舞的重心乃至风格的把握有一些帮助。

Because of the unique of dance elements and aesthetic style in the Han Tang classical dance of China, it is extremely likely to be a typical example of China Dance. Also it is very likely to take its place on the world as a “symbol” dance. Through years of dance learning, I deeply realize that “Center of gravity” is the basic of dance. It plays a key role in the forming of dancing style. The center of gravity is the key of keeping the balance of dancing and the holding of dance style. It is basic of the forming of dance posture and the flow kinetic potential. This paper takes “center of gravity” as the sally port and analyse the internal logic of the Han Tang classical dance of China created by professor Sun Ying. If we regard the Han Tang dance as a culture symbol, the center of gravity is the important form factor of making up the symbol. According to my analysis and study, the center of gravity of Han Tang dance has many features like weightlessness, inequality, etc. Also I discussed the inner link of specialty of the center of gravity, ancients’ aesthetic orientation and professor Sun’s concept. And I realized that the established style of the Han Tang classical dance and the center of gravity has its own relationship. The style brings up the center of gravity and the center of gravity brings up style. The purpose of this text is to hold the essence of the Han Tang dance via the law of motion of the center of gravity and to convey the unique style of the Han Tang classical dance. I hope that through my own research, the dancers, directors and educators can have an elementary understanding of the center of gravity of the Han Tang dance and its style.
