| 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。

| Abstract: | 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 andA is occasionally B.Occasionality 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. |

| Keywords: | possibly not possibility occasionality impure truth-value connective relationship truth-value function |
