【摘要】 当软磁金属材料被加工（如切削、挤压）时，它的内部磁畴结构将会发生变化，其磁性能也有所改变。为了保证产品的一致性，需要对这些加工成型后的金属材料加以分选。本文讨论软磁金属材料的分选原理和实现方法。更多还原

【Abstract】 ：Changes in domain structure of soft magnetic metallic materials will occur if they are machined, and as a result, their magnetic properties will change. Therefore the machined materials should be classified to keep the consistence of qualities. A classifier is developed with function of measurement and classification on the basic of disscusion on classifying principle and method for soft magnetic metallic material.更多还原
