介绍了一种改进的热导探头系统，该系统由探头加热器、控制电路和数据测试系统组成。它具有实验时间短、简单、准确度高、所需样品相对较少等优点。测量时间约为20 s。样品有效体积为50 ml。在这项工作中，用甘油和乙醇校准的探头表现出的准确度分别为1.4%和1.9%。利用该探针系统对橙子汁的导热系数进行了测量。测得的导热系数值与橙子汁的浓度和温度呈线性关系。橙子汁浓度的降低和温度的升高导致导热系数值的增加。而浓度对橙子汁导热系数的影响比温度的影响大。得到了橙子汁导热系数随浓度和温度变化的经验模型。
An improved thermal conductivity probe system consisting of a probe heater, control circuits and data test system was developed and described. It has the merits of the short duration of the experiments, simplicity, high accuracy, and relatively small sample requirement. The measurement time is about 20 s. The effective volume of sample is 50 ml. Calibration of the probe with glycerin and ethanol in this work exhibits an accuracy of 1.4% and 1.9%, respectively. The probe system was used to measure the thermal conductivity of orange juice. The measured thermal conductivity values were linearly dependent on the concentration and temperature of the orange juice. A decrease in the concentration of orange juice and an increase in the temperature resulted in an increase in the values of thermal conductivity. However, the influence of concentration on the thermal conductivity of orange juice was stronger than that of temperature. An empirical model for the thermal conductivity of orange juice as a function of concentration and temperature was obtained.
