针对边界部分有重叠的图象，提出了一种基于网格匹配的快速对准算法，并通过平滑因子对图象实现了无缝拼接。

In this paper, we present a fast stitching algorithm for the overlapping images based on grid matching, which makes images matching correctly, stitching images seamless and smooth.

分析讨论了影响材料体积变化的三个主要因素：有限元网格变形及网格重划、增量步长、惩罚因子，并给出了相应的控制方法。

Three main factors are discussed in detail: deformation of finite element mesh and remeshing, incremental step length, penalty coefficient. Moreover the control ways are provided.
