摘 要: 文章讨论了改进的热平衡积分法的细化.将求解区间[0,s]均匀分划,在所得的子区间内选取适当的近似解析解形式,运用改进的热平衡积分法进行求解.通过讨论得知:细化的改进热平衡积分法能很好地提高所求解的精度. Refinement of the refined integral method is discussed in this paper.Divide the interval evenly partition,select the appropriate form of approximate analytic solution in the obtaining sub-interval,and use the refined integral method to solve.It showed that we can raise the accuracy of solution by using refinement of the refined integral method.
