摘要(中) 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
標準摘要(英) 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.關鍵字(中) ★ 廣義相對論
