  • 摘要

    通过分析在ＲＦ场照射下自旋体系的稳态特性，指出了区分稳态和饱和态的概念是非常必要的。用推广的Ｓｏｌｏｍｏｎ方程描述稳态ＮＯＥ实验，给出了稳态ＮＯＥ实验增强因子的修正表达式，并用实验证明了它的正确性。

     

    Abstract

    The steady-state properties of a spin system irradiated by RF field are analysed. The steady-state NOE experiment is described by the extended Solomon equations. The steady-state NOE enhancement factor is obtained and verified by the experiments of liquids and solids.
