1·This paper tries to generalize the throwing objects from the one dimension pin to the convex curve in two dimension, and even the three dimensional regular tetrahedron and regular hexahedron .
在蒲丰投针问题的基础上，把投掷物由一维的针推广到二维的凸曲线，三维的正四面体、正六面体；
2·Accordingly, a technique for automatic hexahedron mesh of rock-mass with complex structure was realized using multiply mapping mesh.
在此基础上，利用多重映射网格，实现了复杂构造岩体六面体网格剖分；
3·This improved MT algorithm use standard tetrahedron as the initialized mesh unit instead of the tetrahedron dividing from the hexahedron.
该改进的MT算法用标准的正四面体单元取代传统的正六面体单元分割成的四面体单元作为MT算法的网格初始化单元。
4·Based on the structural and movement characteristics of this kind of radial mechanism, a new hexahedron mechanism is proposed.
本文在其结构和运动特点分析的基础上，进一步提出一种新型六面体机构。
5·Integrated block is a generalization of hexahedron around, except to execute components installed side pipe fittings, the other three face plate hydraulic valves can be installed.
集成块的推广，除执行六面体元件安装管讨论，另一边三个面板液压阀可以安装。
