时间之矢的相对性与绝对性

Relativity and absoluteness about a time's arrow

分别从三个方面讨论了时间之矢的相对性与绝对性。结果表明,对应于可逆过程、周期性过程或不存在因果关系的过程,其时间之矢具有相对性;而对应于不可逆过程、非周期性过程或有因果关系存在的过程,其时间之矢则具有绝对性。

In this paper,the relativity and the absoluteness about time's arrow have been analysed in three aspects. The results show that the time's arrow is of a relativity in the processes of the reversible, the periodical and the causeless, but it is of an absoluteness in the processes of the irreversible,the aperiodical and the causal.
