从各向异性电介质中点电荷的电势表达式出发，采取分段计算叠加的方法，首先计算了各向异性电介质中均匀带电矩形线框的空间电势. 然后，利用电场强度与电势梯度的关系，导出了各向异性电介质中均匀带电矩形线框电场强度的空间分布表达式. 最后，对方形均匀带电线框和中心轴线上的特殊情形进行了简单说明.

Based on expression of potential for point charge in anisotropic dielectric and adopting the method of segment calculation superposition，the space potential and electric field strength for uniform charged rectangular frame in anisotropic dielectric are derived. Then，using the relationship between electric field strength and potential gradient，we get the space electric field strength expression for uniform charged rectangular frame in anisotropic dielectric. At last，the special cases of uniform charged square frame and central axis are also discussed simply.
