abstraction levels
抽象层次。在信息可视化与系统设计中指对同一对象可呈现的不同详细程度——从高层概览到具体细节，用户可在不同层次间切换以管理认知复杂度。对应 Shneiderman 经典可视化箴言 'Overview first, zoom and filter, details on demand'。
English Definition
"Different degrees of detail or generality at which a system or concept can be viewed; in information visualization, users can switch between high-level overviews and low-level details to manage complexity."
用法说明 · 针对中文母语者
中文也常说'层次抽象'或'抽象层级'；在论文中 'levels of abstraction'（复数形式）也常见，含义相同。
常见错误
- ·与 'abstraction'（抽象概念本身）混用——后者是泛指名词
- ·误用为'详细信息'——实际强调的是层次切换的能力，而非单层的细节量
