摘　　要：利用均匀设计的实验方法,改变材料的主成份制备MnZn铁氧体材料。用回归分析的方法分别分析了主成份对起始磁导率μi、相对损耗因数tanδ/μi、磁滞常数ηB的影响。研究发现,材料的以上三个特性受二峰位置变化的影响较大,通过合理的主成份配比控制二峰的位置,可以优化材料的特性。MnZn ferrite materials were prepared with different principal components based on uniform design method.The influence of principal components on the initial permeability,relative loss factor and hysteresis constant were analyzed by regression analysis.It was found that material properties were strongly affected by secondary peak.Principal component can change the position of secondary peak,and resultantly,can optimize material properties.
