摘要：

This paper aims to justify the use of statistical mechanics tools in situations where the system is out of equilibrium and jammed. Specifically, we derive a Boltzmann equation for a jammed granular system and show that the Boltzmanns analysis can be used to produce a "Second Law", <(S)over dot> greater than or equal to 0 for jammed systems. We highlight the fundamental questions in this area of physics and point to the key quantities in characterising a packing of particles. accessible through a novel experimentation method which we also present here.
