Abstract: 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.
