摘要 利用B网方法和最小决定集技术,构造了Powell-Sabin(Ⅱ)型加密三角剖分Δ_(PS2)下二元三次C^1样条函数空间的一个最小决定集,给出了该空间的维数和一组具有局部支集的对偶基. In this paper, by using the B-net method and the technique of minimal determining set, the dimension of bivariate Cl cubic spline space S1/3 (△ps2) over the Powell-Sabin's type (Ⅱ) refinement is determined and a locally supported dual basis is constructed.
