The variable geometry truss mechanisms have been studied extensively and systematically by this project. The research plan has been completed all sidedly, and expected results have been obtained. Three new kinds of combination decahedrons and a new class of variable geometry truss mechanism, which is composed of an octahedron and three tetrahedrons connected in parallel form, are proposed. The position analyses for decahedrons, dodecahedrons, triple-octahedrons, combinations decahedron and a new type of structure of variable geometry truss mechanisms are presented by introducing additional extra linear displacement sensors and using resultant elimination and homotopy continuation algorithms. The method of kinematical analysis of variable geometry truss mechanisms is established.

The two-dimensional structural units (such as silicon-oxygen tetrahedral sheet, octahedral sheet), interlayer space are assembled according to the sphere close packing manner, and the close packing layers parallel to {0001}. There are several mechanisms to release the difference in size while the silicon-oxygen tetrahedral sheet and octahedral sheet assemble the TO and TOT-type structural layers. The two types of structural layers with different interlayer space fitted together in six kinds of assembling modes and formed six kinds of crystal layers. The combinatorics analysis of the two-dimensional structural units revealed that there may be 28 kinds of TOT type interstradified minerals in six kinds of polysomatic assembling modes of interatradified structure. The structural layer is symmetrical for octahedron sheet in the structure of interstratified minerals and shows polarity characteristics.

Our calculated results show that the surface face-centered cubic sites are the most favorable sites at 0.25 monolayer, however, the system with a half of the oxygen adatoms taking the fcc sites and the other half taking the octahedral sites between the second and third layer Octa(2,3) is the most stable configuration at 0.50 ML. When the oxygen coverage is larger than 1.0 ML, each of the oxygen atoms prefer separately taking the fcc and octahedral sites such as Octa(2,3), Octa(4,5) and etc. in the alternate layers.
我们的计算结果表明，在覆盖度为0.25单层时，氧原子占据表面面心立方位置最稳定；在覆盖度为0.50ML时，氧原子同时占据表面fcc位置及第二层和第三层之间的八面体Octa(2，3)位置最稳定；在覆盖度大于等于1.00ML时，氧原子喜欢同时占据间隔一个间隙层的表面和八面体间隙位置，如表面fcc位置、第二和第三层之间的八面体Octa(2，3)位置、第四和第五层之间的八面体Octa(4，5)位置等。
