摘　　要：戴礼智于1934年留学英国伦敦大学,师从著名磁学家贝茨从事汞合金磁性研究。戴礼智与导师合作,运用古埃(Gouy)法对已知成分的铋、铬、铜、锰等汞合金的磁化率进行测量,发现除铜外,在固态下显示抗磁性的金属,其汞合金均显示顺磁性;发现锰—汞合金的磁化率具有温度滞后现象;此外,还研究了滴定法磁化率测量。文章以戴礼智的博士论文、档案及发表论文为基础,回顾并分析了上世纪30年代戴礼智在汞合金磁性方面的实验研究工作,以了解当时中国物理学界在此方面的贡献。新的史料也提供了戴礼智在英国留学的情形。Tai Li Chi engaged in the study of amalgam magnetism with his mentor, the famous physicist L.F. Bates when he studied in University of London in 1934. Tai Li Chi and L.F. Bates measured the magnetic susceptibility of the known components of bismuth, chromium, copper, and manganese amalgam using the Gouy method. They found that, in addition to copper, metals that were diamagnetic in the solid state exhibited paramagnetism in the amalgam state;the susceptibility of manganese-amalgam showed temperature hysteresis. In addition, they studied the titration method in magnetic susceptibility measurements. A review and analysis of the experimental research of Tai Li Chi is presented based on his dissertation, files and papers in the 1930s, which may help us to understand the status of this field in China and also know Tai＆#39;s studies in UK ac-cording to the new historical data.
