Introduction to relaxation time

The relaxation time is the time required to reach thermal equilibrium. It is a characteristic time of the dynamic system. The time required for a certain variable of the system to change from a transient state to a certain stationary state. In statistical mechanics and thermodynamics, the relaxation time represents the time required for the system to move from an unstable steady state to a stable steady state. In synergetics, the relaxation time can characterize the degree of influence of fast variables, and a short relaxation time indicates that fast variables are easily eliminated.
