摘要
根据WBR理论 ,采用“改进的矩阵计算方法” ,计算出了强偶合体系较为完整、准确的弛豫方程组 ,并根据此方程组分析研究了J偶合对横向弛豫、纵向弛豫和交叉弛豫的影响 。
According to the WBR theory and by means of the “Promoted matrix computation method”, the authors computed and studied the relaxation equations of strong coupling system, especially the effect of J coupling on transverse relaxation, longitudinal relaxation and cross relaxation. Finally the authors gained the following valuable conclusions. (1) The effect of weak coupling on the computation of relaxation is very small and neglectable. (2) The strong coupling has hardly any effect on the computation of transverse relaxation. (3) The strong coupling has a certain extern effect on the computation of longitudinal relaxation and cross relaxation, especially this effect achieves maximum when the match condition ω\-a-ω\-b≈2πJ comes into existence and can't be neglected.
