  1. The level first frequency variety regularity following the pre - stressing cable value is achieved through white noise sweep checking. the conclusion that model is in elastic work stage is achieved

    對結構模型進行了振動臺試驗，採用白噪聲對結構模型進行掃頻分析，得出結構水平第一振型對應頻率隨拉索預應力值的變化規律。
  2. 3. the effect of measurement error is considered as gauss white noise. through theoretical analysis and numerical simulation, damage assessment results are also subject to gauss distribution. furthermore, results indicate that the mean keeps intact, but the standard deviation is linear to error level

    3 、將測量誤差的影響考慮為正態分佈的高斯白噪聲，通過理論分析和數值模擬，說明用靈敏度分析法識別結構損傷時，損傷識別結果也服從高斯正態分佈，其平均值保持不變，而方差則與誤差水平成線性關系。
  3. In chapter 4, i performed the analyzing work with wavelet and fastica and find that wavelet was a high efficient way to filter the cep signal when i set the wavelet and scaling function to haar, decomposing level to 4, threshold method to fixed to threshold and white - noise structure to scaled white - noise. it took the advantage that reduced the accumulating times to 60 with more smooth signal and less distortion. but fastica takes no advantage on this facet

    本文通過小波變換和獨立分量快速分析模式識別的方法對cep數據進行了分析處理，同時與數字低通橢圓濾波器的處理效果進行了比較，發現用小波對cep的數據進行濾波處理時，可以將數據的疊加次數從120降低到60次左右，且信號的質量要比以前的處理方法好；但是獨立分量快速分析方法效果不很好。
