The book provides a new approach to the description of friction processes. It explains the simultaneous coexistence of alternative friction models, and prognosticates the possibility of quantum and relativistic effects manifestation in macromechanical systems such as friction units. Consideration of measurement as a process of defining the output parameters of tribosystem is carried out with the apparatus of second quantization and conceptions associated with non-local quantum effects. Such approaches make it possible not only to take another look to the evolution of tribosystems, but also to discover previously unknown regularities of friction.
