Typical models of statistical systems in thermostat

The statistical description recognizes that any complex system in an equilibrium condition possesses stationary states. Solving stationary equations of Shredinger, can be found dependence of energy of stationary states Ei and number of stationary states (statistical weight) Г from volume V or other external parameter of system х, numbers of particles in system N. It is usual if to not mean complexity of her decision, a problem of quantum mechanics of the isolated system.
