【摘要】 在力学中，许多反问题有其重要的工程背景。采用系统控制论的描述，所谓反问题就是逆系统辨识问题。本文利用基于神经网络的逆系统辨识方法对力学反问题进行求解。并给出了材料力学参数反求和裂纹长度的反求两个算例更多还原

【Abstract】 By employing the method of small parameter expansions, the mode localization of twin control surfaces with asymmetrical parameters is studied in the paper. It is an emphasis of the present paper to study the effects of asymmetrical parameters on the mode localization of the twin control surfaces. The mechanisms of mode localization are also disscused.更多还原
