摘　　要：对原为第一类边值问题的非线性常微分方程采用并行打靶的方法,寻求原问题相对应的初值问题,将其转换为Volterra型积分方程组离散求解,并采用外推技术进一步提高解的精度.同时,对问题的存在性,唯一性,以及算法的收敛性均进行了讨论,并取得较好的数值结果.Parallel shooting method was used to transform the boundary problem into initial problem,further transform it into integral equations and seek its discrete solution by using trapezoid formula.In order to achieve better precision order,extrapolation techniques were used too.The problems of existence,uniqueness,convergence of the algorithm were discussed,and had good numerical results.
