摘　　要：用临界态模型对热均衡压方法制作的高质量密度Ｔｌ２Ｂａ２Ｃａ２Ｃｕ３Ｏ１０块材样品在低磁场下的磁化曲线进行了模拟计算并与实验结果进行了对比。计算结果表明这种方法制作的样品有较高的粒间临界电流密度。The critical state model is used to perform the simulate calculation for the low magnetic field magnetization loop of high mass density Tl 2Ba 2Ca 2Cu 3O 10 bulk sample made by hot isostatic press method. The results show that the sample has a high intergranular critical current density. The information of the dependence of the intergranular critical current on the magnetic field is obtained by the crtical state model simulate calculation.
