重构_改善既有代码的设计

说明：  本文提出的自动频域分解是受到[1,2]引入的频域分解(FDD)的启发。目的是识别在环境噪声下土木工程结构健康监测中获得的加速度记录的振型、特征频率和模态阻尼比。(The automatic frequency domain decomposition proposed in this paper is inspired by the frequency domain decomposition (FDD) introduced by [1,2]. The purpose of this paper is to identify the mode shape, characteristic frequency and modal damping ratio of acceleration recorded in the health monitoring of civil engineering structures under environmental noise.)
