Abstract
The basis for defining and measuring temperatures is an equilibration process. In externally unforced systems the equilibration process is the time evolution, driven by entropy, toward the thermodynamic equilibrium states. In the systems subjected to external forces the equilibration process is a time evolution representing the approach from a more detailed level of description to constitutive relations on a less detailed level. This approach is driven by the CR entropy that in the absence of driving forces and after the approach is completed becomes the dissipation potential (a quantity closely related to the entropy production).
期刊介绍：
This journal is of a multi- and inter-disciplinary nature and covers a broad range of fields including mathematics, computer science, physics, chemistry, biology, earth sciences, and their intersection. History of science is also included within the topics addressed by the journal. The transactions of the Pelorian Academy started out as periodic news sheets containing the notes presented by the members of the Divisions into which the Academy has been and still is organized, according to subject areas. The publication of these notes for the Division (“Classe”) of Mathematical, Physical and Natural Sciences is the responsibility of the Editorial Committee, which is composed of the Director of the division with the role of Chairman, the Vice-Director, the Secretary and two or more other members. Besides original research articles, the journal also accepts texts from conferences and invited talks held in the Academy. These contributions are published in a different section of the journal. In addition to the regular issues, single monographic supplements are occasionally published which assemble reports and communications presented at congresses, symposia, seminars, study meetings and other scientific events organized by the Academy or under its patronage. Since 2004 these transactions have been published online in the form of an open access electronic journal.
