ducted 是形容詞，描述某物配備管道、通過管道輸送的，或具有管道狀結構的。其核心含義源于名詞 "duct"，意指用于輸送流體（如空氣、氣體、液體）或容納線纜等的通道或導管。
以下是其在不同領域的詳細解釋與應用：
基本定義與結構特征
工程與技術應用（暖通空調 HVAC）
醫學與解剖學應用
"Ducted" 的核心概念是存在或涉及管道。它既可以描述物理結構（如管道式空調、腺體導管），也可以描述通過管道實現的輸送方式（如管道送風）。其具體含義需結合上下文，尤其在區分工程系統（如 HVAC）和生物結構（如解剖學）時。
“Ducted” 是一個多義詞，具體含義需結合語境理解，主要分為以下兩類：
基本含義
表示“管道中的”或“通過管道輸送的”，常用于工程、醫學等領域。例如：
擴展場景
作為動詞duct 的過去式或過去分詞，表示“通過管道輸送”或“用導管封住”。例如：
如需進一步了解具體領域（如醫學或工程）的用法，可參考詞典或專業文獻。
