摘　　要：对涉及纯Ni、纯Co及WC-Co硬质合金的比饱和磁化强度值的文献进行了分析研究,发现部分论文(20多篇)的数值(以A·m2/kg为单位)约为正常值的4π倍。研究结果表明:这种情况产生的原因,对于比饱和磁化强度测定值,估计是有关作者在进行电磁量的单位换算时出现了失误;而对于由相关数据所得的比饱和磁化强度计算值,是由于其测定的饱和磁化强度值约为正常值的4π倍所致。为便于分析讨论问题,对有关物理量的定义及相应的单位换算公式也作了相应介绍。Study is made of the literatures in respect of specific saturated magnetization value of pure Ni,Co and WC-Co cemented carbide.In more than 20 articles are indicated that the specific saturated magnetization value is about 4π times of the normal value( A·m^2/kg).The results showed that for the measured value,this is due to the author's mistake in the unit conversion of electric magnetism quantity; while for the calculated value based on related data,it is due to the fact that the measured specific saturated magnetization value is about 4π times of the normal value.Corresponding description is also made of the definition of the related physical quantity and corresponding unit conversion expression are presented for the convenience of discussion.
