摘　　要：概述了液态金属电阻的测试方法 ,利用直流恒流四电极法测量原理建立了固 液金属电阻率连续变温测试装置 ,并利用该装置对合金Pb6 1 .9Sn38.1 及固体非晶Zr57Nb5Cu1 5.4 Ni1 2 .6 Al1 0 的电阻率进行了连续变温测量 ,验证了该装置测试的可靠性。The methods of measuring the electrical resistivity of liquid metal were reviewed. The instrument of solid-liquid metal electrical resistivity measurement during the temperature continuous change by four-probe method was designed and made. The electrical resistivity of the solid-liquid Pb 61.9Sn 38.1 and bulk solid metal glass Zr 57Nb 5Cu 15.4Ni 12.6Al 10 were measured by means of the instrument, and it is proved that the instrument is available.
