Geometrical Parameters to Icosahedron, Ortho-pentagonal Dodecahedron and Their Applications in Quasicrystal Lattices

In this paper the geometrical parameters to icosahedron and orthopen-tagnal dodecahedron are obtained.Two kinds of 3-dimension quasicrystal lattices are discussed. A new kind of lattices with the characters of or-thopentaqnal dodecahedron is given.By the geometrical parameters,otherkinds of 3-dimension quasicrystal will be dealt with.
