摘　　要： 用符拉索夫薄壁理论计算曲梁,必湎求解一个含有8N个方程的线性方程组(N是结构单元数)。按常规算法需占用大量的计算机内存。本文提出一个新的方法,使这一计算能在袖珍机和微机上完成,整个程序仅占不到5K内存。主要作法是:1.对非零矩阵块的系数采用数据压缩存放。2.各类结点条件作为一个子程序,3.采用列主元消去法。 When the thin-wall curved beam is solved by vlazov's thin-wall theory, it is necessary to work out the solution of bighter-order hear equations which content the 8N equations, where N is the number of structure element. According the common algorithm, enormous memory space will be occupied. In this paper the authors put forward a new algorithm which can make this kind of structure to be solved by microcomputer, even pocket computer. The memory space for source program is less than 5k bytes.
