摘　　要：本文研究了一类奇异线性两点边值问题的数值解法,利用拉格朗日插值理论与积分插值法,使格式的收敛阶达到O(h4).本文最后列举了一些数值试验结果,这些结果验证了理论结果.In this paper,a kind of Numerical solution method for a Class of singular linear two- point boundary value problem is studied,By using Lagrange interpolation theory and integral interpolation method,Make scheme order of convergence to. Finally,we present some numerical results which illustrate and support our theoretical results.
