Abstract:	既然重力場中不存在能量與動量之密度，則應致力於尋求各守恆量之準局域量．本文繼同一系列研究之後，探討在廣義相對論理論中之質心距之準局域量，由此非但可以再次驗証Nester-Chen expression之有效性，更能顯示質心距較其他守恆量對各種表示式理論提供更嚴格之檢驗標準 Having recognized the absence of energy and momentum density for the gravitational field, conserved quasilocal quantities over finite 3- dimensional regions are the best that can be expected. Nester-Chen expression for the quasilocal center-of-mass moment was investigated. Not only the result agrees with the expectated asymptotical limit value but also the center-of-mass moment behaves as a more strict criteria for the validity of the expression.
