摘要
制备了一个简易绝热型热量计，并用此热量计实测了 ７ 种非均相电解质水溶液在 ５～６０℃范围内不同温度区间的比热容，提出了比热容与温度的经验关联式⒚关联式的计算值和实验值的平均相对偏差均小于 １％ ⒚热量计采用标准物质正庚烷标定，装置的测量精度为 ０．９％
A conventional adiabatic calorimeter was constructed and the specific heat capacities of 7 heterogeneous aqueous electrolytes have been measured at the temperatures from 5 ℃to 60 ℃. The correlation of specific heat capacity with temperature has been presented. The average deviations between the calculated and measured values were within 1%. Calorimeter is calibrated by n heptane, which is the standard reference substance for calorimetry. The accuracy of measurement was about 0.9 per cent.
