In order to improve the resistivity of oxidation, dysprosium cobalt ferrite magnetic fluids were prepared.摘要为了提高磁流体的抗氧化能力，制备了镝钴铁氧磁流体。
Influences of temperature on magnetic property and stability, mechanism of dysprosium modification on the magnetic prope利用古埃磁天平研究了温度对磁性和稳定性的影响；研究了稀土镝磁性能的改性、表面活性剂的表面改性，并从理论上进行了分析。
