摘要
本文用B-网方法确定了△_(nm)^((2))剖分上二次双周期样条函数空间的维数,给出了插值条件的几种提法,证明了解的存在唯一性.
This paper determins the dimensions of double periodic quadratic splines on type-Il triangulations by using B-Net. It also gives several kinds of formulations of interpolation conditions and proves the existence and uniqueness of the interpolation.
