Elimination of Reversibility Paradox in Time Reversal Processes

Abstract：

A more rational scheme of time reversal transformation is provided in the paper. In the new scheme, the transition probabilities are invariable under time reversal in the electromagnetic interaction processes of pure sates. But the evolutions of macro-processes can’t keep unchanged under time reversal owing to the interference effects of probability amplitudes between non-pure state processes. In this way, the so-called reversibility paradox, i.e. time reversal is reversible in micro-processes but irreversible in the macro-processes, can eliminated completely.
