摘　　要：本文用静态法测定了五种含盐水溶液的饱和蒸气压,并根据实验数据总结出含盐水溶液饱和蒸气压与温度、浓度及盐离子价数之间关系的一个经验公式。用此公式所得计算值与实验值及文献值相吻合,为某些需控制相对湿度的场合提供了一些水盐恒湿体系。The vapor pressure has been measured by the static method for five salt-containing aqueous solution sys- tems. A experimential equation has been established by these experimental data in order to describe the de- pendence of vapor pressure on temperature, salt' s concentration and ionic valence. The computation values obtained by this equation agree with those values of experiment and literature. The constant humidity systems of salt-containing aqueous solution have been supplied for some situations controlling the ralative humidity.
