【摘要】 目的研究优质天然饮水的团簇结构特征。方法选用17O-NMR为监测指标,用ARX400型核磁共振波谱仪测定不同水样(天然饮水、人工制水)的团簇结构。结果测量了21个代表性水样的17O-NMR半高幅宽在53～145Hz范围内。结论优质天然饮水的17O-NMR半高幅宽一般都在70～90Hz的范围内。更多还原

【Abstract】 Objective To study the characteristic cluster structure of good-quality natural drinking water.Methods The coupling 17 O NMR(nuclear magnetic resonance)FWHM(full width half maximum)was selected as the index to weigh the rel-ative average size of water cluster in liquid water.The 17 O NMR FWHM of water samples(nature water and artificial water)were measured by ARX400NMR spectroscopy.Results 17 O NMR FWHMs of21representative water samples were in the range of53-145Hz.Conclusion 17 O NMR FWHM of good-quality natural drinking water mainly lay from70to90Hz.更多还原
