摘要
从热力学基本理论出发,解释了磁制冷材料的磁热效应,并推导出等温熵变ΔSm和绝热温变ΔTad的基本公式,为选择合适的磁制冷材料提供了理论依据。
Magnetocaloric effect in magnetic refrigeration has been analyzed by using thermodynamic theory. The formulae of magnetic entropy change ｜ΔSm｜ and adiabatic temperature change ΔTad have been deduced. The selection principle of magnetic refrigerant materials has been given.
