以下转自wikipedia

Opacity or opaque refers to something difficult to see through or perceive. It can refer to:

• Opacity (optics), material through which visible light does not pass through.
  
• Opaque context, a linguistic context in which it is not possible to substitute co-referential terms while guaranteeing the preservation of truth values.
  
• Opaque data, data that can only be manipulated through an external interface in order to preserve abstraction.
