本文应用实验室坐标系Bloch方程,引入δ函数代替快扫相关核磁共振(NMR)原理阐述中的线性化处理,导出自旋脉冲响应函数,指出该理论与实验之间的一一对应关系,进一步闸述了该波谱法的原理。本文还做了快扫相关NMR 在DJS-130 计算机上的模拟,该模拟指出了快扫相关NMR 的主要特点和注意问题,为实际谱测量条件和参数的选择提供了依据。
In this paper, we use the laboratory coordinate system Bloch equation to introduce the δ function instead of linearization in the description of fast scan correlation nuclear magnetic resonance (NMR) principle, derive the spin impulse response function, point out the one-to-one correspondence between the theory and experiment Clarified the principle of the spectroscopy. In this paper, we also do the simulation of fast-sweep-related NMR on DJS-130 computer. The simulation points out the main features and attention problems of fast sweep-related NMR, which provides the basis for the actual spectral measurement conditions and parameters selection.
