摘要
提出一种描述自旋为１／２的强偶ＡＢ自旋体系多脉冲ＮＭＲ实验的密度算符演化的方法，推导了自旋算符的自由演化公式，具体描述了极化转移ＩＮＥＰＴ实验和二维ＤＱ－ＩＮＡＤＥＱＵＡＴＥ实验。该方法物理意义直观，计算量较小。
A new formalism was proposed to describe the evolution of density operators inmulti-pulse NMR experiments for the strongly coupled AB spin systems（I=1／2）； Theevolution formula of spin operators were derived．The polarization transform INEPTexperiment and two-dimensional DQ-INADEQUATE experiment were deseribed． Theformalism is distinct on physical meaning and requires less ealculation。
