摘　　要：以实例图形概念，应用稀疏矩阵三角块分技术及非线性数值迭代技术，提出了有效的包括几何约束表达、有效性检验、约束分解及求解的约束满足策略。该策略还支持不完备几何约束的约束满足。A strategy for geometric constraint satisfication is presented with the application of the concept of case graphics, sparse matrix triangular blocking and nonlinear numerical iteration technologies. The strategy includes several constraint satisfication technologies, such as representation, identification, decomposition and solution. Futhermore, this strategy supports the decomposition and solution of underconstrainted geometric constraints.
