摘　　要：研究热阻、热漏及回热损失等不可逆因素对以顺磁盐为工质的Ericsson制冷循环性能的影响,分析和讨论循环的重要性能参数及优化工作区域,所得结论为磁制冷机的优化设计和性能评价提供参考。The effect of the irreversibilities including thermal resistances, thermal leak and regenerative losses on the performance of a magnetic Ericsson refrigeration cycle, in which a paramagnetic salt is employed as the cyclic working substance, is investigated. The important performance parameters of the cycle and their optimal operating regions are analyzed and discussed. The results of this study provide some new information for use in the optimized design and the performance evaluation of magnetic refrigerator
