摘　　要：通过对桥梁结构的总刚半带宽最小时的节点排列特征进行分析,归纳总结出三条规律,运用AD算法进行节点优化排序,并结合桥梁结构的特点进行了算法优化。应用VC++编制了面向对象的带宽优化程序,通过算例对比验证了程序的正确性和可靠性,结果表明:该方法能够优化出很佳的半带宽值,并大大减少了计算机内存占有空间,提高了运算效率。This paper makes an analysis on the order features of the nodes when the network bandwidth is the minimum value and presents three rules. Considering the feature of bridge structure, the AD algorithm is optimized and the object oriented bandwidth optimization program is developed. The correctness and reliability of the program are proved by testing a large number of examples. The procedure takes an arbitrary input sequence and creates an optimal bandwidth for complex network system by renumbering the node labels, thus, considerable improvement for computer storage and operating efficiency is achieved in the solution of the systems.
