摘要
采用两种快速算子θ和Φ以及离散算子Ｅ，研究并解决了两个问题：计算多个曲面（或平面）切割另一曲面形成的局部表面面积，以及多个曲面（或平面）围成的复杂几何体体积。解决了参数化设计中常见的一些几何特征求解的工程问题。
Two kinds of rapid operatorsθand,cornbined with a discreting operator E,are used in this paper.With these operators, local surface area problem, where the local area is formed by cutting a surface with many kinds of curved surfaces. or planes. Further, many complex geometry volumes used in aircraft configuration design are calculated. The software programmed in these algorithms has both effectiveness and acceptable accuracy for characteristic value calculation problems in parametric design.
