摘要
在研究电力、电信传输问题时,两根平行圆导线或两个圆柱形导体之间的电场、电势可以采用柱面镜像法计算,这种方法归结为一对电轴的电场、电势问题。本文引进双极坐标,在描述电场、电势的分布,以及计算不同情况下的电容问题时,显得更加简单、方便,由此看出选择适当的坐标系所带来的优点。
Cylindrical mirror image method can be used to calculated the electric field and potential between two parallel round wires or two cylindrical conductors in the study of electricity and telecommunications transmission, which is reduced to the electric field and potential problem of a pair of electrical axis. In this paper, the bipolar coordinate are introduced, and it is simpler and more convenient to describe the distribution of electric field and potential, and to calculate the capacitance in different cases. It shows the advantages of selecting the appropriate coordinate system.
