摘　　要："水是H2O"是克里普克提出的后验必然命题的例证。一些国外学者对"水是H2O"作为一个后验必然命题提出了质疑。Helen Steward认为,"H2O"不是严格指示词。Mark Johnston认为,水是H2O不应该被看作同一性命题,而只是其构成的命题。实际上,这些看法是错误的,而且论证也不合理。"水是H2O"作为一个后验必然命题的示例是不容置疑的。Water is H2O is an example of necessary posteriori propositions, which has been questioned by some foreign scholars. Helen Steward claims that H2O be not a rigid designator, and Mark Johnston argues that the statement of Water is H2O＂should be viewed as claims of constitution but not of identity. The authors of this article think that none of their viewpoints is correct and the related demonstration is unreasonable as well. That the view- point of Water is H2O＂ is viewed as necessary posteriori propositions can not be doubted.

关 键 词：水 H2O 后验必然命题 合理示倒
