【Abstract】 The accuracy solution of resistance values between electrodes for two dimensional infinity boundary is derived.The numerical calculation of resistance between electrodes for limited two-dimension area is carried out.By contrasting the results for infinity area and limited area,it is shown that the numerical method is feasible.On the basis of the nu-merical analysis,the influences of the distance between border and electrodes on resistance are analyzed;and the cacula-tion shows that rectangular electrodes save20%～30%metal material in comparison with the rounded ones on the condi -tion of equal resistonce.更多还原
