ABSTRACT
In the study of the nonequilibrium properties of the system, averaging is not so trivial. Therefore, a method for averaging is also addressed in this book. We propose averaging over an ensemble of statistically independent initial values of the coordinates and velocities of the system. Choice of the system size for simulations of nonequilibrium properties is also important. According to the analysis in this book, the necessary system size may not be larger than several tens or hundreds of particles in the basic cell.
