摘　　要：采用等温蒸发法研究了四元体系Na+,K+//NO 3-,Cl--H2O在298 K时NaNO3-KNO3共饱曲线的介稳程度及湿度对该共饱曲线介稳程度的影响。结果表明:在298 K时,不管在高湿度还是在低湿度下该四元体系的NaNO3-KNO3单变量曲线介稳现象均不明显。Metastable equilibrium of univariant curve of NaNO3-KNO3 and the influence of humidity in the quaternary system Na^＋,K^＋//Cl^-,NO3^--H2O were studied at 298 K by isothermal evaporation method.According to the experimental data,metastable equilibrium didn＇t occur obviously in the univariant curve of NaNO3-KNO3 not only at lower humidity but also at higher humidity.
