Furthermore, the advantages of the genetic algorithm and the above single layer neural network are combined to yield a new identification technique. The network topology is employed to replace the procedure for solving the governing equation when GA is used to identify the system parameters of both the SDOF system and the MDOF system with or without noise contamination. The comparison is made between the predicted acceleration and the measured one for each case.

另外，结合类神经网路与基因演算法於结构动力参数识别，首先应用前述之单层类神经网路架构做为系统动力模式，再藉由基因演算法搜索符合该系统之权重值，然后将权重值代入网路架构以取代解微分方程式求得系统反应，最后再与量测反应做比较；同时亦利用该方法应用於进行识别含杂讯之输出入资料的系统权重值，以验证该方法应用於单自由度线性系统及多自由度线性系统识别之可行性。

With this method,goodresults were obtained in the leaf of spinach and Chinese ilex,atypical double layer film system.

在典型的双层薄膜体系菠菜叶子和冬青树叶子中，应用本文的方法对样品的双层体系的光声吸收进行了分离，得到了合理的结果。

Achieved through bitmap layer, if to do simple image editing software, you can refer to this example.

详细说明：通过位图实现了图层，如果做简单的图像编辑软件，可以参考这个例子。

By anchoring an imaginary spring between each data point and deformable curve or surface, the fairing model is established. Then FEM is used to solve the deformation problem of the model caused by imaginary springs and a bicubic B-spline surface patch is taken as one element. Lastly the B-spline active surface model is applied to surface reconstruction from layer data and the problem resulted from fitting for uneven cross-sectional curves can be solved.

通过在数据点与模型之间连接虚拟弹簧，建立光顺模型，并以双三次B样条曲面片作为单元，运用有限元法对模型在虚拟弹簧作用下的变形问题进行求解，得到光顺后的B样条曲面；并在此基础上，提出了一种新的基于断层数据的表面重建方法，可很好地解决不均匀截面族的曲面生成问题。
