| 摘 要： | 简单介绍了时不变ARMA模型的数学描述，并阐述了结构参数与ARMA模型参数之间的对应关系：通过实例分析说明了ARMA模型用于工程结构识别的可行性；最后用一维ARX模型和ARVX模型对同一结构进行识别，从而得出多维模型在结构识别领域有更广阔的应用前景。

| Abstract: | In this article, time-invariant ARMA model is simply introduced and the relationship between physical parameters of structure and parameters of ARMA model is detailed described;system identification using ARMA mode is proved to be feasible through several examples; the identification to the same structre based on two models displays its advantage of ARMAV model in the field of system identification. |
