摘　　要：居里温度的测量是通过对磁滞回线随温度变化的定性观测和磁化强度随温度变化的定量测量完成的。对定性测量中热磁特性的微观机理和定量测量中的数据处理进行了分析和研究,以期能够引导学生学会分析实验现象并能科学地处理实验数据。The measurement of Curie temperature is accomplished by the qualitative observation of the hysteresis loop with temperature and the quantitative measurement of magnetization with temperature.The microscopic mechanism of the thermal magnetic properties in the qualitative measurement and the data processing in the quantitative measurement are analyzed and studied in order to guide the students to learn to analyze the experimental phenomena and to deal with the experimental data scientifically.
