2 ~! R7 _- P* a2 L  jRheological behavior of a material depends on time and space scales of observation (experiment). The former is important as a measure of the ratio of the rate of inherent processes in a material to the time of experiment and/or observation; the latter determines the necessity to treat a material as homo- or heterogeneous. Rheological properties of a material can be understood via balance (or conservation) equations (equations of solid state continuum or fluid dynamics), being a method to transit from properties at a point to an observed behavior of an item or a medium as a whole. The results of macroscopic description of behavior of real engineering and biological media, based on their rheological properties, are used in numerous applications related to technology of synthesis, processing, and shaping of different materials (plastics and ceramics, emulsions and dispersions in the chemical and food industries, pharmaceuticals, cosmetics, transport, oil industry, etc.), theirlong-term properties, natural phenomena, such as movement of mud streams and glaciers, and biological problems (dynamics of blood circulation, work of bones). One can conclude that the first goal of rheology is a search for stress versus deformation relationships for various technological and engineering materials in order to solve macroscopic problems related to continuum mechanics of these materials.
2 w! `8 z' c2 f+ a5 {The second goal of rheology consists of establishing relationships between rheological properties of a material and its molecular composition content. It is an important independent problem related to estimating quality of materials, understanding laws of molecular movements and intermolecular interactions. The term microrheology, related to classical works by Einstein,4 devoted to viscous properties of suspensions, is sometimes used in this line of thought, and it means that the key interest is devoted not only to movements of physical points but also to what happens inside the point during deformation of a medium.
