The vapor heat capacities as a function of temperature at 101. 3kPa of three binary systems, acetone-chloroform, benzene - carbon tetrachloride and benzene-ethanol, were measured in a multicomponent vapor flow calorimeter constructed in this laboratory.

• 用自行建立的多组分气体流动热量计测定丙酮-氯仿、苯-四氯化碳和苯-乙醇3个二元体系于不同温度、不同组成时的常压汽相热容。
