摘　　要：本文建立了一个新的数学模型并提出一种基于变量流技术的变量设计方法．尺寸函数和几何交切函数的划分与建立避免了求解繁琐的约束方程．我们以全交互方式建立基型和确认通道，由系统自动提取约束并实现尺寸驱动，解决了任意复杂图形的参数化问题，并易于适应新的变化．In this paper, a new mathematical model is founded and a variable parameter design method based on variable flow technology is put forward. The dimension function and geometry intersection and tangency function is classifiedand set up, so that the solving of restraint equations is avoided. Basic type and affirm cycle are built interactively.The system picks up restraints and achieves dimension-driven automatically. The parameterization problems of arbitrary complicated graph are solved.
