摘　　要：裁剪分析是膜结构设计过程中的关键，为此，本文提出一种有效的方法——动态规划法，把空间任意曲面近似展成平面。即基于动态规划的基本思想，把空间任意曲面划分成有限个相邻的条块（称之为条元），依次耦联计算出每一条元的展开形状，便可得到整个曲面的展开图。This paper suggests a useful effective method——Dynamic Programming Method(DPM) for approximate transformation of an arbitrary curved surface into a plane. Patterning is very important in designing curved surface, especially in manufacturing processes for transformation of curved surface into a plane. DPM is that, an objective curved surface is decomposed into regions of adjacent strips. Then, each region (or strip) is developed in turn into a flattened shape. The whole shape is derived by solving multi stage decision processes. Finally, two examples are pressented by way of illustration.
