贴上一点前后文：
Product modularity is a property of product architecture. Products can be ‘‘modular’’ or ‘‘integral’’ depending on the allocation of the functions to the modules and on the nature and the number of the interfaces. In a pure modular product architecture each module performs only one function and interfaces are standard. Fixson develops a tool for assessing product architecture and classify products depending on the level of modularity. He specifies three main characteristics of interfaces: nature, reversi- bility and standardization. Product modularity implies that changes in one module of the product require few or no changes in other parts of the product.

典型中式英语，十有八九翻译软件的杰作。改成：natural,reversible and standard

自然

没有同意替换的地方，几个释义里只有特性和自然比较贴切，但是这里在说产品模块化，我觉得材料特性恐怕接近原意
