综述了反对称孪生幂（AGP）态的各种表达式。利用BCS（Barclay，库珀，and Schrieffer）型态的产生和湮灭算符的简单关系，对AGP和GAGP（广义AGP）方案刻画了这类算符.这些运营商的一阶约化密度矩阵的退化的效果显示。
Various expressions for antisymmetrized geminal-power (AGP) states are reviewed. With the use of a simple relationship for creation and annihilation operators of BCS (Bardeen, Cooper, and Schrieffer)-type states, such operators are characterized for AGP and GAGP (generalized AGP) schemes. The effect of degeneracy in the first-order reduced density matrix on these operators is displayed.
