- 1(管狀或中空的身體部位)擴張。瞳孔則常說放大;眼科會說散瞳。
If a hollow part of the body dilates, it becomes wider. Something can also dilate it. Doctors use this constantly: pupils dilate in the dark, or when drops are put in; blood vessels dilate when you are hot; in childbirth the cervix dilates so the baby can come out. It is a biology and hospital word in this sense, not a playground word. There is an older use too, to dilate on a subject, meaning to talk about it at length — to spread the words out — though students meet the body meaning far more. A different, rarer history once also gave English a dilate meaning “to delay”; that is not this sense, and you can leave it alone.
組成From Latin dīlātō (“to spread out”), from dī- + lātus (“wide”).
