摘　　要：依据形式代数（ｆｏｒｍｅｘａｌｇｅｂｒａ）理论，用ＦＯＲＴＲＡＮ语言编制了实用程序，使外形比较复杂的球面网壳、椭球形网壳、双曲抛物面形及筒壳等形式的网格结构能够利用计算机自动成形，避免了以往冗长、单调且易于出错的结构成形工作，与计算机辅助图形相结合，既直观又便于修改和检查．通过工程实例来说明形式代数在空间网格结构自动成形中的优越性和很强的实用性．Using formex algebra theory,this paper compiles procedure in FORTRAIN language in order to configurate automatically for a structure of special shape,such as globe,hyperboloid and paraboloid ,etc,and avoid previous tedious work. The procedure is combined with computer aided graphics aspcts,so it is apt to modify and check data.It is evident that formex algebra theory is of value in configuration of space grid structrue of special shape.

关 键 词：形式代数 空间网格结构 计算机 自动成形
