摘　　要：本文运用非平衡态统计算符方法[1],研究了海森堡磁流体的能量输运现象,讨论了外磁场对其能量输运的影响,并计算了海森堡模型磁流体系统在非均匀外场中能流的平均值.Using the method of nonequilibrium statistical density operator, we studied the energy transport of the Heisenberg magnetic fluid. The influence of an applied magnetic field on the energy transport was discussed, and the average value of the energy flux was calculated in the presence of the uniform and nonuniform applied magnetic fields.
