【摘要】 <正> This paper is continuance of the paper[1]. A numerical calculation method of the Schwartz-Christoffel integral mapping the upper half plane onto the exterior of the polygon is discussed. The transformation formulas to deal with singular integral and the iteration equations to deal with the unknown parameters in the Schwartz-Christoffel integral are given. And this method is applied conformally to map the upper half plane onto the exterior of the polygon with the close cracks. And更多还原
