dilate

Dilate是英語動詞，源自古法語，英式與美式發音均為[daɪˈleɪt]，第三人稱單數、現在分詞、過去式及過去分詞分別為dilates、dilating、dilated。作及物動詞時意為“使擴大/膨脹”，作不及物動詞時指物體自身“擴大/膨脹”或引申為“詳述”。其構詞源自前綴“di-”（分開）與詞根“late”（釋放），意為“分開放→擴大”。

該詞主要用於生理學及醫學領域，描述血管、瞳孔等結構的擴張現象，如瞳孔對光線變化的反應（Pupils Dilate）或擴張型心肌病（dilated cardiomyopathy）。在臨床中亦用於手術操作（如球囊導管擴張肺動脈瓣）及藥物作用（擴張動脈血管）。此外，其短語動詞形式“dilate on/upon”表示詳細闡述，派生名詞“dilater”指醫學擴張器械。該詞被柯林斯詞典列為TEM8級辭彙，常見於專業語境。
