摘　　要：With the calculation and measuring experiment methods,the effect of vacuum chamber materials' magnetic permeability on field distribution in a dipole magnet is discussed.The results show that when the relative magnetic permeability of chamber materialμ_r≠1,it will affect the field uniformity.Once the high field uniformity is required, the material property and size of vacuum chamber in a dipole magnet have to be taken into account carefully.通过计算机模拟计算与实验相结合,讨论了真空盒磁导率对二极磁铁磁场分布的影响.结果表明当真空盒磁导率μ_r≠1时,真空盒将影响磁铁磁场分布,在磁场均匀性要求很高时,必须考虑真空盒的材料与尺寸对磁场均匀性的影响.
