IP Switches greatly expand the number of segments while restring the flattened topologies of bridged environments, thus multiplying the opportunities for broadcast storms.

IP交换大大扩展了段时恢复桥路环境下的平面拓扑结构因此广播风爆机倍增。

The goal of the mesh optimization algorithm is to re duce the number of the triangles in the mesh,and keep the accuracy of the interp olation at the same time.

求工程中曲面求得到的据模型虽然可以映零件的拓扑结构，但网格上的三角形的量一般比较大。
