然后，提出了以推进波前法与映射法相结合处理裁剪曲面的三角剖分方法，并给出了具体的实现算法。

Then, the paper put forward method used to Triangular segmentation of trimmed surface by combining the Advancing Front Technique with Mapping Technique, and afforded its special algorithm .

本文首先利用状态空间法结合三角级数展开技术，对简支的FGM梁、板、圆柱壳结构进行了弹性理论分析。

So, we employ an elasticity method, i. e. state space method, to analyze the simply-supported FGM beams, plates and cylindrical shells.
