【摘要】 本文用密度矩阵计算了在弱相互作用下,自旋都为1/2的核的A、AX、AMX与AFMX四种体系以及自旋都为3/2的核的A与AX两种体系中的各种量子相干。获得了它们的数目的比值以及它们的数目的总和。本文还扼要地描述了这一研究结果的可能应用。更多还原

【Abstract】 In this paper, quantum coherences under weak interaction in A, AX, AMX and AFMX systems of which spin quantum number 1/2is,and in A and AX systems of which spin guantum number is 3/2 are calculated by using the density matrix. Their numeral ratio and their numeral sum are got. The potential applications of results of the study are also described,更多还原
