摘要
从第一类积分方程的反演求解入手,推导出了适合低场脉冲核磁共振横向弛豫信号多指数反演的一种解谱算法。对解谱的具体过程进行了详细论述,并对不同信噪比、不同布点方式下的解谱结果进行了对比与分析。本算法对推广低场脉冲核磁共振分析测量技术的应用具有重要的参考价值。
Based on the inversion method of Fred Holm integral equation, a multi-exponential inversion algorithm is derived for resolving spectra of pulsed NMR transve-rserelaxation signals in low field. The resolving process is discussed in detail. The resolved results of NMR spectra under different S/N ratio and different space-time mode are compared and analyzed. This method is valuable for promoting the application of low field pulsed NMR measurement technology.
