Abstract
The implications of the dense random packing (DRP) model are discussed, with an expectation that it may represent a possible structure model for perfect amorphous solids. The topological definition of the DRP is argued on the basis of Sadoc's idea that the DRP is an assembly of spheres, close-packed in a curved non-Euclidean space and mapped onto the linear Euclidean space. Thermal properties of the DRP, especially excess entropy, are also discussed in this context. Discussions are evidenced by the observed changes in structures and thermal properties of metallic glasses due to particle bombardments and cold works. Similar arguments prove to apply for systems such as amorphous silicon and amorphous silica.
