摘　　要：本文采用高精度光电计时粘度计及单茎毛细管密度瓶分别测定了在２８８．１５～３２８．１５Ｋ温度区间内，氨基乙酸和ＤＬ－氨基丙酸在１ｍｏｌ·ｋｇ￣（－１）Ｎａ＿２ＣＯ＿３水溶液中的粘度及密度数据；计算了两种氨基酸在该溶液中的粘度Ｂ系数及极限偏摩尔体积；拟合出了粘度Ｂ系数与温度的关系方程；讨论了氨基酸的引入对Ｎａ＿２ＣＯ＿３水溶液结构的影响规律；用流动过渡状态理论得到了两种氨基酸在１ｍｏｌ·ｋｇ￣（－１）Ｎａ＿２ＣＯ＿３，溶液中的流动活化参数．The viscosities and densities of glycinc and DL-alanine in 1mol·kg￣(-1) sodiumcarbnate aqueous solutions were mcasured at 288.15～328.15K with the high precise viscometer and thesingle stem pycnometer.The viscosity B coefficients and the limiting partial inolar volumes were calcu- lated.The equation was related with the least-squares method between the B coefficients and tempera-ture. The influence on the structure of 1mol·kg￣(-1) Na_2CO_3 was discussed and the flow activationparameters of two amino acids in 1mol·kg￣(-1) Na_2CO_3 aqueous solutions were obtained.
