摘要
作为逻辑联结关系的“偶然”是一种特殊的可能:同时也可能不的可能,即,可能不如此的可能,或者说是,有与之不相容的可能情况的可能。作为逻辑联结关系的“风马牛”是一种最彻底的、最特殊的偶然。A风马牛B,当且仅当,A偶然B且A偶然B。偶然和风马牛都是2元的非纯真值联结关系。不是为正统数理逻辑所研究的纯真值联结词。
Occasionality, as a logic connective relationship, is a special possibility： at the same time it is a possibility that is not possible, that is, a possibility that is not like this, or a possible state that is not compatible with this. Irrelevance, as a logical relationship, is a kind of the most complete and special occasionality. A is irrelevant to B if and only if A is occasionally B and ┐ A is occasionally B. Oecasionality and irrelevance are both binary connective relationships of a impure truth-value, and they are not pure truth-value connective for the study of orthodox mathematical logic.
