本文测定了己内酰胺７水（重水）．二甲基乙酰胺／水（重水）和丙烯酰胺７／水（重水）体系中Ｎ－１４在低浓度区域的弛豫时间，考察了四极弛豫的溶剂同位素效应，虽然所研究的酰胺分子大小不一，但在无限稀释的溶液中，仍然可以表明这些酰胺分子的运动完全受溶剂分子的控制。
This paper measured the caprolactam 7 water (heavy water). The solvent isotope effect of the quadrupole relaxation was examined for the relaxation time of N-14 in the low concentration regions in dimethylacetamide / water (heavy water) and acrylamide 7 / water (heavy water) systems. Although the amide molecules studied In varying sizes, in infinitely diluted solutions it is still possible to show that the movement of these amide molecules is completely controlled by the solvent molecules.
