摘　　要：NdFeB粘结磁体中的磁粉与粘结剂含量影响着磁体的磁性能和机械强度等物理性能,合理的组分设计有利于满足不同的使用要求。本文通过对磁粉模型的设计和计算,得到了磁粉与粘结剂的最佳组成比例,而实际制备磁体时两种组分的比例要略高于理论值。It is needed to get proper ratio of magnetic powder to binder in bonded NdFeB magnet, because it influences magnetic and mechanical performance. A model of magnetic powder is proposed to deduce the proper proportion of magnet components and the relevant formulae are given in the article. The amount of binder needed in reality is slightly higher than that of the theoretic calculation.
