Abstract: On the basis of solving two-dimensional electrostatic field distribution by combining with the plane mirror method and conformal mapping,the induced charge distribution on the conductor curved surface is solved,the function of the surface charge density is got,and the curve of the function of the induced charge density are plotted by using mathematical software MATLAB.

Key words: conformal mapping, plane mirror method, electric field distribution, induced charge distribution
