| 摘 要： | LPSCD法是目前线性预测法取代FFT在实践中最有意义的方法之一。本文建议在LPSVD之后作等比指数加权处理可改善HRNMR谱的分辨率,并保留高分辨NMR谱的所有特征。甚至可以用线段的集合重构高分辨谱,它与原FFT谱具有同样的化学位移、强度和积分。

| Abstract: | In practice, LPSVD is one of the most interesting linear-prediction techniques instead of FFT now. In this paper, a method is proposed by means of proportional exponential weighting which is performed after LPSVD, one can keep all characteristic parameters in HRNMR-spectra and improve their resolution, so far as a spectrum can be reconstructed by a group of lines with the same chemical shifts, intensities or integration of FFT spectra. |
