  1. At the same time, the program corresponding to the proposed method is compiled in fortran90, which is used to analyze the influence of several factors on behaviour of barrettes, including ratio of length to width, ratio of depth to equivalent diameter, ratio of modulus of pile to soil, possion ' s ratio, the finite layer etc. many useful conclusions are obtained from the above analyse

    該方法考慮了壁板樁樁身橫截面的非軸對稱性，並用fortran語言編制了相應的程序，進而分析了多種因素對壁板樁承載特性的影響，包括長寬比、樁徑比、樁土剛度比、泊松比以及有限壓縮層深度等。
  2. Absorption - band parameters such as the position, depth, width, and asymmetry of the feature have been used to quantitatively estimate composition of samples from hyperspectral data. so spectral absorptions are very important feature bands in use of hyperspectral classification and targets identify, this paper extracts absorption features of actual hyperspectral image by continuum removed method which is very useful. then tested both of them by

    吸收峰波段參數例如波長位置、深度、寬度、斜率、對稱度、面積等常常被用來定量的估計高光譜樣本的組成，因此光譜的吸收峰是高光譜識別分類應用中很重要的特徵波段，論文通過包絡線去除這種很有效的光譜分析工具提取出了實際的高光譜圖像的地物光譜的吸收峰參數。
