摘要
本文定义了平面单连通多边形域的一类较任意的三角剖分－分层三角剖分，并通过分析二元样条的积分协调条件，确定了分层三角剖分卜三次Ｃ１作条函数空间的维数．
In this paper, a kind of so-called stratified triangulation is defined. By analysiug the integral conformality condition of bivariate spline. we determine the dimension of space of cubic splines over stratified trianglulation.
