摘　　要：对近年来在制冷界研究相当活跃的磁制冷的工质，尤其是近室温磁制冷的工质——铁磁材料，在外加磁场中的热力学特性进行了分析、讨论，并在此基础上总结了选取近室温磁制冷工质的理论依据和原则，使实际中的选择工作有了针对性，减少了盲目性．Refrigerants of magnetic refrigeration have been studied actively in the field of refrigeration these years.The thermodynamic characteristics of magnetic refrigerants in aded magnetic field,especially ferromagnetic material,which is used as refrigerant of magnetic refrigeration near room temperature,have been analyzed and discussed in this paper.On the basis of this,theoretical basis and principle of selecting refrigerant of magnetic refrigeration near room temperature has been summarized.This makes the selecting work less aimless in reality.
