| 摘 要： | 用数理统计方法研究了粉末烧结Ｎｄ－Ｆｅ－Ｂ永磁体磁性能的均匀性，分析发现，粉末取向度对均匀性有很大影响，随装填密度增加，取向度变小，磁性减弱，分布的离散度变宽。磁体磁通量的分布受成分、取向磁场和密度等多种随机因素的影响统计结果比较好地服从正态分布

| Abstract: | Magnetic homogeneity and flux distribution in Nd Fe B magnets have been studied using a statistic method. The results show that the distribution of magnetic flux is affected by various random factors such as composition, orientational field, and magnetic flux density. The statistic results conform well to a normal Gaussian distribution. Moreover, the main factor affecting magnetic homogeneity is the orientation degree of the easy axis of the powders. |
