研究了由自旋为1的玻色子组成的N-体系统的总自旋态.导出了具有{N}和{N-1,1}对称性的总自旋态的母配分系数.这些系数使有关矩阵元的计算大为方便.因而它们将有助于建立一个关于旋量玻色爱因斯坦凝聚的改进了的理论,其中总自旋S及它的Z-分量Sz均得以守恒.
研究瞭由自鏇為1的玻色子組成的N-體繫統的總自鏇態.導齣瞭具有{N}和{N-1,1}對稱性的總自鏇態的母配分繫數.這些繫數使有關矩陣元的計算大為方便.因而它們將有助于建立一箇關于鏇量玻色愛因斯坦凝聚的改進瞭的理論,其中總自鏇S及它的Z-分量Sz均得以守恆.

The total spin-states of a N-body system with spin-one bosons have been investigated.The fractional parentage coefficients for the total spin-states with {N} and {N-1,1} symmetries have been derived.These coefficients facilitate greatly the calculation of related matrix elements,they appear as a powerful tool for the establishment of an improved theory for the spinor Bose-Einstein condensation;spinor bosonic systems;fractional parentage coefficients.
