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(duì)偶積分方程,將裂紋面上的位移差函數(shù)展開(kāi)為雅可畢多項(xiàng)式的級(jí)數(shù)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(shù)速度的legendre多項(xiàng)式逼近,進(jìn)一步給出了參數(shù)速度的插值區(qū)間端點(diǎn)的jacobi多項(xiàng)式逼近,由此導(dǎo)出了保持法矢平移方向的兩個(gè)等距代數(shù)有理逼近算法
