摘　　要：应用等温流动微量热法测定298．15 K时甲酰胺与肌醇分子在不同浓度氯化钠水溶液中的混合过程焓变及其稀释焓,根据McMillan-Mayer理论关联得到各级异系焓相互作用系数(h_(xy),h_(xxy)及h_(xyy))．结果表明,甲酰胺与肌醇分子在氯化钠水溶液中的异系焓对相互作用系数h_(xy)均为负值,并且随着氯化钠浓度的增加,h_(xy)的绝对值逐渐减小．The enthalpies of mixing of formamide with myo-inositol and those of their dilution in aqueous sodium chloride solution of different concentration were determined by using flow-mix-isothermal microcalorimetry at 298.15 K. These results were used to determine heterotactic enthalpic interaction coefficients （hxy, hxxy and hxyy） according to the McMillan-Mayer theory. The results show that heterotactic enthalpic pairwise interaction coefficients hxy were negative in aqueous sodium chloride solution and became less negative with increasing the concentration of sodium chloride.
