求解包装动力学在受到脉冲下的冲击谱,来算具体响应规律 (response shock spectrum)

Finland Matlab cannot do regular meshes for non-regtancular regions. However, one can manually do very coarse regular meshes for these type domains. The difficulty is with the edge data e. If this data does not correspond to the orientations given by the PDEtool geometry files, refinement will not work. The function drawedges() will display the order of the edges and their segment numbers. However, this function does not tell how the edges are oriented. However, just run the visualization, and if the refinement does not work correctly, you know the problem is with the orientatino of the edge. Remember to also correct the last two rows of the matrix e when changing the orientation. (See the documentation for initmesh for more info.)

趋势面分析是拟合数学曲面的一种统计方法。通常要找到一个合适的曲面精确表达实际问题往往比较困难，但却可以利用多项式函数来近似逼近它。(trend surface analysis is fitting surfaces of a mathematical statistical methods. Usually to find a suitable surface accurately reflect the actual problems are often more difficult, but polynomial function can be used to approximating it.)
