摘要: 本文研究了in Vivo NMR实验中的水峰抑制问题.通过结合予饱和和1-2τ-5,4-τ-5,4-2τ-1硬脉冲序列,水峰抑制系数达到1000以上.从而为研究微量代谢产物创造了条件.

Abstract: Water-suppression is introduced into OSIRIS localized in Vivo spectroscopic technique. By combining presaturation and selective detection episodes, a suppression factor of > 1000 could be readily obtained. The technique could therefore be used to detect and study metabolites in Vivo.

Key words: in Vivo NMR, Water suppression, Presaturation
