| 摘 要： | 为变参绘图系统中的约束求解提供了一个新思路。采用该思路，不但可以通过分解和排序来提高求解速度，而且可以通过快速地指出约束不足和约束过载来提高灵活性和可靠性。文中详细介绍了该思路的原理，并给出了相应的算法。

| Abstract: | In this paper we propose a new method for parametric design based on graph model and operations.With the aids of graph decomposition and topological sorting this method can not only speed up geometry evaluation,but also detect under constrained and over constrained conditions in the parametric design.It makes features of high flexibility and reliability. |
