ABSTRACT. Ruelle's principle for turbulence leading to what is usually called
the Sinai-Ruelle-Bowen distribution (SRB) is applied to the
statistical mechanics of many particle systems in nonequilibrium
stationary states. A specific prediction, obtained without the need
to construct explicitly the SRB itself, is shown to be in agreement
with a recent computer experiment on a strongly sheared fluid. This
presents the first test of the principle on a many particle system far
from equilibrium. A possible application to fluid mechanics is also
discussed.
