Abstract : this paper discusses high order numerical model of non - linear boundary equation . by using integral technique , the boundary condition problem is turned into a form initial condition problem . we construct 4 order numerical formula . the convergence theory is given and proved . the examples show that our method has fast convergence speed and less numerical time 文摘:討論非線性邊值問題的一種高精度計算模型.利用積分值將邊值問題轉(zhuǎn)化為形式初值問題,構(gòu)造了一類四階精度的計算格式,證明了收斂性.通過算例表明該方法收斂速度高,計算量小
