Model, Logical Structure and Main Characteristic of the SAM System of Classical Thermodynamics

The Surrounding Analysis Method called the SAM is a kind of advanced classical thermodynamics theoretical system. The SAM is found on the recent research about the nature of object and the principle of conversion of energy. It studies the equilibrium of system and the changing course of state from root causes called inner cause and outer causes. A more religious logical structure is found in the SAM. In the paper, the thermodynamic model, logical structure and main characteristic of the SAM system are introduced emphatically. The logical structure of the SAM is more reasonable and more understandable. Thermodynamic energy is taken as original nonfinite definition. The definition of entropy change is given directly in the SAM. The SAM takes heat, work and mass flow as independent interactions. The general expressions of the basic laws in the SAM have more inclusiveness and more universal applicability. The SAM has the more applicability in teaching and practice.
