摘要:
An experiment with a spring is described to illustrate the fact that the irreversibility involved in a physical process in transforming the system from an initial state to a terminal state bears an inverse relationship to the number of discrete steps in which it is carried out, leading to the conclusion that the process becomes reversible as the number of steps tends to infinity. A similar relationship is shown to hold for processes like charging of a capacitor and compression of a perfect gas.
