在测得转轮内部的绝对速度矢量后，按速度三角形原理进行分解，得到了绝对速度切向分量、相对速度及相对速度切向分量。

The absolute velocity was decomposed based on the law of velocity triangle, the absolute tangential velocity, the relative velocity and the relative tangential velocity were presented in this paper.

该法在行波法生成平面三角形网格的基础上，将一个三角形单元分解为三个四边形单元。

Based on the advancing front technique developed for triangular mesh generation, quadrilateral mesh can be generated by dividing each triangular element into three quadrilateral elements.

ROAM算法就是通过采用分解和合并方法实时地调整三角形网格，能交互式地实现观察依赖、局部可调整的地形网格化处理，生成多分辨率的地形模型。

ROAM method adopts split and merge operations to adjust triangle meshes, can interactively perform view-dependent, locally-adaptive terrain meshing and can construct multiresolution terrain model.
