摘　　要：In order to investigate the effect of magnetic field on the liquid-liquid extraction, the extraction in the acetone-water-trichloroethane system was studied under magnetic field with different magnetic induction intensity.The results showed that the effect of magnetic field was positive in the extraction process, and the partition coeffi-cient and the yield of acetone increased-with the increasing magnetic induction intensity by 5.16%-8.35% and 1.85%-5.70% respectively. The effect of magnetic field on the extraction was intensified when the temperature became, higher. The experimental data of the partition coefficient of acetone were correlated by the method of least square in terms of a power-law correlation.以便在液体液体抽取上调查磁场的效果，在 acetone-water-trichloroethane 系统的抽取与不同磁性的正式就职紧张在磁场下面被学习。结果证明磁场的效果在抽取过程是积极的，并且分区系数和丙酮的收益与增加增加了磁性的正式就职紧张由 5.16%8.35% 和 1.85%5.70% 分别地。当温度变得更高时，抽取上的磁场的效果被加强。丙酮的分区系数的试验性的数据被最少的平方的方法以幂定律关联相关。
