| | In this paper, we study the relations between the existance uniqueness of interpolation with boundary condition using bivariate quadric splines connected with triangular partition and positions of interpolating points. After proving the existence uniqueness of interpolation. Problems at center, vertex and partial center, we give the construction methods for these three interpolating functions. | | 本文研究(Ⅱ)型三角剖分下带边界条件的二元二次样条插值问题的存在唯一性与插值节点分布的关系,并且在证明了中心插值、角点插值和偏心插值问题解的存在唯一性的基础上,给出了这三种插值函数的构造方法。 | | 文摘来源 | | Using the B-spline basis of Bidimensional spline spaceS_2 ̄1(△_(mn)(2)).We discuss the centre interpolation spline function with appropriate boundary conditions. For the first time.We obtain the Asymptotic expansion of non-tensor product interpolating splines. Further more,we get the brief succinct Asymptotic expansion and super-convergence results at spe cial points (error bounds O(vh4))under the boundany condition (B). | | 利用二元样条空间S_2~1(△_(mn)~(2))的B样条基,本文讨论了带适当边界条件的中心插值问题,首次获得了非来积型二元样条插值的误差渐近展开.进一步,在边界条件(B)下,得到了十分简洁的渐近展式和在特殊点上的超收敛结果. | | 文摘来源 | |   |
