摘　　要：对埃特金算法每次迭代需要计算两次函数值的缺点进行了改进,改进后的埃特金算法利用前次计算的函数值,每次迭代只需再计算一次函数值,从而大大提高了优化迭代计算的效率与自动化程度,其在结构优化中的应用算例验证了该算法的可行性和优越性.In order to conquer the defect of Aitken algorithm of requiring twice value in an iterative, ameliorated Ttiken algorithm is proposed. This algorithm uses the message of the last iteration, so only one value is required in an iterative. The efficiency and the automatic degree is much advanced. The feasibility and superiority of this algorithm have been authorized through examples.
