ducted 是形容词，描述某物配备管道、通过管道输送的，或具有管道状结构的。其核心含义源于名词 "duct"，意指用于输送流体（如空气、气体、液体）或容纳线缆等的通道或导管。
以下是其在不同领域的详细解释与应用：
基本定义与结构特征
工程与技术应用（暖通空调 HVAC）
医学与解剖学应用
"Ducted" 的核心概念是存在或涉及管道。它既可以描述物理结构（如管道式空调、腺体导管），也可以描述通过管道实现的输送方式（如管道送风）。其具体含义需结合上下文，尤其在区分工程系统（如 HVAC）和生物结构（如解剖学）时。
“Ducted” 是一个多义词，具体含义需结合语境理解，主要分为以下两类：
基本含义
表示“管道中的”或“通过管道输送的”，常用于工程、医学等领域。例如：
扩展场景
作为动词duct 的过去式或过去分词，表示“通过管道输送”或“用导管封住”。例如：
