中文摘要：
在温度为298.15-343.15 K,质量分数为25%-100%的条件下,采用Calvet微量量热仪测定了室温离子液体四氟硼酸1-乙基-3-甲基咪唑（[Emim]BF4）及其水溶液体系的比热容。建立了该体系的比热容与温度和浓度的经验关联式,并比较了该体系的差示扫描量热计（DSC）所测得的实验数据和现象。研究认为Calvet微量量热法更适于测量含挥发性溶剂的体系。
英文摘要：
The heat capacities of the ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate （[Emim] BF4） and its aqueous solutions with weight fraction in the range 25 % -100 % have been measured using a Calvet microcalorimeter at temperatures from 298.15 to 343.15 K. The variation in heat capacity with temperature and concentration has been studied. The results obtained were compared with those using DSC （Differential Scanning Calorimetery）. It is concluded that the Calvet microcalorimeter is more appropriate than DSC for determination of the heat capacity of systems involving volatile species.
