The central concept of microbiologically influenced corrosion is ‘biofilm’. However, it is neither a 100% biological fabric nor a film. While biofilms though mechanisms such as establishment of differential aeration cells can accelerate corrosion, under certain circumstances such as thickening may also decelerate corrosion. In this article, these mechanisms will be discussed. Along with that, this author also introduces a new term that can replace the term ‘biofilm’. This new term, ‘temenos’, has been proposed to indicate that when a biofilm forms, electrochemical conditions under the biofilm and those of the bulk will be highly different from each other.

受微生物影响的腐蚀的中心概念是“生物膜”。但是，它既不是100％的生物织物也不是薄膜。尽管通过诸如建立差异化曝气池等机制的生物膜可以加速腐蚀，但在某些情况下（例如增厚）也可以使腐蚀减速。在本文中，将讨论这些机制。随之，作者还引入了一个新术语，可以代替术语“生物膜”。已经提出了这个新术语“ temenos”，以表明当形成生物膜时，生物膜下的电化学条件与主体条件下的电化学条件将彼此非常不同。
