摘要：

An air cushion table that we have built and tested has been used to study the structure of 2D assemblies of identical discs of increasing density, going from very dilute systems up to the most compact crystalline array. We analyse the radial and angular distribution functions, calculated from an image analysis treatment, and the progressive structuration of these assemblies. The disorder-order transition is observed for a packing fraction close to the theoretical value of 0.82. It is confirmed by a study of the geometry of the Voronoi polygons.
