geometrical constraint meaning in English

几何约束

At first every method of constraint solving is presented in this paper . through comparing the advantages and disadvantages of one method with another the method of constraint solving based geometrical constraint graph in which geometrical constraint system is expressed by graph , and which can deal with over - constraints and down - constraints is proposed
本文首先总结了二维参数化设计中的各种约束求解方法，并权衡每种约束求解方法的利弊，提出了基于几何约束图的约束求解方法，此方法是用图来表示几何约束系统，能够有效地处理欠约束和过约束的情况。
