【摘要】 介绍了将小波多分辨分析 (MRA)用于核磁共振 (NMR)自由感应衰减 (FID)信号的水峰抑制。结果表明 :这是一种能有效抑制NMR强水峰的数据后处理方法。该方法操作简便 ,引入畸变信息少 ,抑制效果好 ,对邻近水峰的共振峰影响小 ,可得到相位纯正、基线平坦的谱。更多还原

【Abstract】 Wavelet multi-resolution analysis has been used for suppressing water peak in free induced signals of NMR. The experimental results demonstrate that this is an effective data post-processing technique to remove strong water signals. The method is simple to operate and the spectra with pure phase and flat baseline can be obtained.更多还原
