中文摘要：

从电磁尺度变换关系出发，考虑了由于尺度伸缩所引起的空间电磁特性的变化，得到了导体椭球上的电荷分布表达式，在椭球的3个半轴相等时，该表达式退回到导体球上的电荷分布；将所得结果与有关文献结果进行了数值比较，发现本结果更优．

英文摘要：

The expression of electric charge distribution on the surface for an ellipsoidal conductor is presented by utilizing the electromagnetic scale-transformation and the space electromagnetic characteristic. This expression is agreement with that for a conductor sphere when the three semi-axis a, b and c are equal. Compared with research results in the literature, the results that were obtained from this study shows that it is better than that in the literature.
