摘要
By means of Side-Israeli’s quadrature reules, quadrature methods for solving boundary integral equations of the first kind are presented, which have high accuracy O(h3). Moreover, the asymptotic expansions with the odd pwoers h2μ-1 （μ= 2, 3） of the errors are shown, that is, using extrapolations, we can improve the accuracy order of approximations..
By means of Side-Israeli's quadrature reules, quadrature methods for solving boundary integral equations of the first kind are presented, which have high accuracy O(h^(3)). Moreover, the asymptotic expansions with the odd pwoers h^(2μ-1) (μ= 2, 3) of the errors are shown, that is, using extrapolations, we can improve the accuracy order of approximations..
