| 摘 要： | 对于直言命题的变形推理，传统上认为0命题不能换位。本文通过欧拉图我们可以证明以全称命题为前提的换质位法推理中0命题是能够换位的。它完全符合传统的直言命题变形推理规则。

| Abstract: | Regarding deformed reasoning in categorical proposition, people think that the O-proposition can not been converted on tradition. In fact, it is possible to exert conversion on O-proposition in conversion by contraposition inference which takes the premise by the universal proposition. It conforms to the tradition to deformed reasoning rule in categorical proposition. |
