A New Frame Work of Thermodynamics (1) Traditional Thermodynamics, (2) Thermodynamics of Thermal Electrons in a Static Magnetic Field, (3) Cosmos Thermodynamics

This new frame work of thermodynamics contains three parts. First, the traditional thermodynamics: relating to all the ordinary thermodynamical processes we meet in our daily life and work, and in ordinary research. They are all irreversible. Entropy in these processes tends to increase, never decrease. Second, thermodynamics of thermal electrons in a magnetic field:Some experiments of thermal electrons emitted from two identical and parallel Ag-O-Cs emitters (work function 0.8eV) in a vacuum tube applied by a static magnetic field. The magnetic field is an artificial Maxwell’s demons. Third, cosmos thermodynamics: The universe is closed. There is an extraordinary heat ocean at a temperature of about 3K in the central part of the closed universe. A big band and a big assembling constitute a big cycle, the matter and energy in the closed universe are involved in an extraordinary big cycle; Entropy can increase, and it can also decrease. Black holes are natural demons in the universe.Besides, there is a supplementary file On Bekenstein and Hawking’s Black Hole Thermodynamics attached to this article, showing that Bekenstein’s “area entropy” is an incorrect idea, and so on.
