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.

Gastaldi and co-workers have observed two types of contrasts in Al-Pd-Mn IQCs: black-white double-lobe and loop-shaped, by using X-ray topography, and the facetted dodecahedral pores by phase-sensitive radiography.
Gastaldi领导的小组在结合利用X射线形貌术以及相位敏感成像术研究Al-Pd-Mn二十面体准晶单晶中的缺陷时发现两种衬度，其中已知黑白双瓣衬度是由于准晶中的五角十二面体空洞引起，而对于环形衬度则除了知道退火行为不同于位错从而不太可能是位错圈外，基本上对其缺陷的几何及性质不甚了解。

Goldberg got a class of polyhedra which are icosahedral symmetry by appending hexagons on regular dodecahedron by rule in 1937. They are called Goldberg polyhedra which provides a new approach for polyhedral molecule design.
1937年，数学家Goldberg通过在正十二面体上有规律地添加六边形面得到一类具有二十面体对称性的多面体，即Goldberg多面体。
