摘　　要：简单介绍了室温磁热效应测量仪的工作原理及组成,并且测量了Gd样品的磁热效应T-ΔTad曲线,该仪器具有操作简单方便、测量费用低廉等优点,它可以作为室温磁制冷材料研究的重要测量手段,同时也可以解决目前磁制冷材料普遍只研究等温磁熵变的不足的问题。This paper simply introduces the make-ups and working principle of the room temperature magne-tocaloric effect （MCE） direct measurement device. And the MCE T-△Tad curve of the rare earth metal Gd sample is measured. This device has many advantages such as simple operation and low measurement cost and so on. Therefore this device can serve as important means to research room temperature refrigerants. Meanwhile its measurement results can solve the problem of a lack of △Tad data in the resent room temperature refrigerants research field.
