| 摘 要： | 本文计算量子数为整数的纯体系与混合体系的各种量子相干。推导出密度矩阵的阶数、鼻子相干数目的总和、最高量子数等公式。本文利用体系的每一个能级的总本征态,可由体系中每个核的有关的本征态叠加而成这一性质,使原有计算手续大为简化。这种方法在大自旋量子数及多核的复杂体系的计算中,更显示出它的优越性。

| Abstract: | The quantum coherences of different kinds for the pure systems and the mixedsystems with integral quantum-number were calculated. And the formulas were de-duced. The following nature was used also, i. e. the total eigen-state of everyenergy--level of the system may be added together to costitute by the relative eigen-state of every nucleus in the system. By this nature, the original calculating--pro-cedures were greatly simplified.In the calculation of complicated system with the bigspin quantum-number and many nuclei, the superiority of this method were moreshown up. |
