To solve the dual integral equations , the jumps of the displacements across the crack surfaces are expanded in a series of jacobi polynomials 為了求解對偶積分方程,將裂紋面上的位移差函數展開為雅可畢多項式的級數形式。
After giving the legendre polynomials approximation to parametric speed of the curve , the author gives the jacobi polynomials approximation to parametric speed with endpoints interpolation . from this , two algebraic offset approximation algorithms , which preserve the direction of normal , are derived 給出了曲線參數速度的legendre多項式逼近,進一步給出了參數速度的插值區(qū)間端點的jacobi多項式逼近,由此導出了保持法矢平移方向的兩個等距代數有理逼近算法
