摘要: 利用正规乘积算符内的积分技术(IWOP),导出了在相干态│z〉过完备性中,积分变量:与z^*可以独立地做积分变换,而保持其完备性.利用相干态的这一特点和IWOP积分技术,进而可以方便地证明粒子数平移态D(z)In〉具有过完备性.

Abstract: The completeness of the coherent state is proved by using the technique of integration within the ordered product (IWOP) ,where the integral variables z and z^* have been preformed independent transformation. Both the completeness and the property of the coherent state of the displaced Fock state D(z) │n〉 are also proved by using the IWOP.

Key words: IWOP, eigen state, Fock space, operator
