摘　　要：将正交实验法用于环氧树脂粘结SmFeN磁体的矫顽力性能实验中,通过对实验数据的方差分析,确定了外磁场、氮化温度及球磨时间(微粒度)对该磁体磁性影响的显著水平及最佳的工艺,并对环氧树脂粘结SmFeN磁体的矫顽力机理作了初步探讨。An orthogonal experimental method was employed to conduct the experimental study of the coereitity of epoxy resin bonded Sm2 Fe17 Nx magnets. Through a variance analysis of the test data the effect of the various parameters on the magnets was ascertained along with a determination of the optimum structural parameters of the magnets. This led to an optimum design of the latter; meanwhile, the coereivity mechanism of the Coereivity of Epoxy Resin Bonded Sm2Fe17 Nx magnets was discussed in detail.
