The utilization of the above fact is discussed under the purpose of error estimation. Using the result of potential theory, several important properties of the error are enumerated. For example, 1) the point at which the error is maximum appears on the boundary, 2) the error of the derivative of the solution along an arbitrary direction is also harmonics and ③ the error is solenoidal and irrotational. Numerical experiments are consistent with above properties. It is concluded that for the absolute error estimation the checking of the error only on the boundary is necessary and sufficient. It is pointed out that the easiness and certainty of the error estimations should be emphasized in the charge simulation method.}, pages = {115--121}, title = {代用電荷法における誤差の性質について}, volume = {18}, year = {1976} }
