The article is based on a previous suggestion by the author to introduce a new temperature scale — named after the German physicist Boltzmann. The proposition is repeated in short, then some practical consequencies are demonstrated. The ideal gas law will take on a simpler form and the molar heat capacities will turn into dimensionless quantities. The universal gas constant and the Boltzmann constant are shown to be superfluous conversion factors. It is further demonstrated how an empirical scale for the Boltzmann temperature can be established and how dimensional analysis can be performed. Some examples from statistical mechanics show that the Boltzmann temperature is well suited when deducing the basic relations in this field. It is emphasized that the proposition does not affect the theory of thermodynamics, it only draws conclusions from well known facts. In traditional thermodynamics the so-called barometric equation is taken to actually measure the Boltzmann constant. Such measurement has no meaning in the Boltzmann temperature idiom, the result of the measurement is in this notion the Loschmidt (Avogadro) number. The molar entropy becomes a pure, dimensionless number, a property which corresponds well to the real nature of entropy. The relation to the thermodynamic probability of a state is established, and a different form of the Boltzmann equation S=k In W is given. 相似文献

feature resonance and so break down as t → ∞. The classical methods of averaging and multiple scales eliminate such secular behavior and provide asymptotic solutions
valid for time intervals of length t=O(ε−1). The renormalization group method proposed by Chen et al. [Phys. Rev. E 54 (1996) 376–394] gives equivalent results. Several well-known examples are solved with these methods to demonstrate the
respective techniques and the equivalency of the approximations produced. Finally, an amplitude-equation method is derived
that incorporates the best features of all these techniques. This method is both straightforward to automate with a computer-algebra
system and flexible enough to allow the forcing f to depend on the small parameter
This paper is dedicated to Jerry Kevorkian with sincere appreciation for his long career of dedicated teaching at the University
of Washington and for his substantial contributions to multiscale asymptotics 相似文献
