This variation of stresses is due to the action of in - plane shear strain in the plate, which is termed “ shear - lag ”. stresses larger than the elementary bending uniform stress thus develop at the web - flange connection. an appropriate reduced “ effective width ” of the plate - with the uniform stress equal to the maximum longitudinal stress - has been widely used by engineers in conjunction with the elementary beam bending theory
但實際上翼緣中剪切變形是不均勻的，由此導致正應力沿橋寬呈曲線分佈，從而引出了有效寬度的概念，即按初等梁理論的公式也能得與真實應力峰值接近相等的那個翼緣折算寬度。 -
This paper is described wavelet transform theory, mother wavelet choice, the method to filter signal by wavelet transform and the result, prospered a way to extract feature originated from wavelet theory, which using wavelet packet analyzing method to subdivide signal both in low frequency and high frequency field, and consider energy of every layer as feature in frequency field, and in conjunction with the detailed analyzing character of wavelet packet in time - frequency plane, consider several minimum or maximum points in the lowest frequency band a s features in the time field
本文介紹了小波變換的理論、基小波的選擇和利用小波變換進行信號濾波的方法和濾波處理結果，並提出了一種基於小波理論的新的特徵值提取方法。即利用小波包分析方法將信號在低頻、高頻段作進一步的細分，以各層分解的能量作為信號的頻域特徵值，以最低頻帶的極值點作為時域特徵值，這樣的特徵值選取方法較全面的反映了信號的時-頻特徵，優于傳統的傅里葉分析方法。
