- 1圓柱體（形狀）；汽缸（引擎部件）
A cylinder is a solid or hollow shape like a tube or a can — it has two flat, round ends and straight sides. Tin cans, some water bottles, and are all cylinder-shaped. In cars, 'cylinders' are the tube-shaped parts inside the engine where fuel burns to make the car move — that's why you'll hear about 'a four-cylinder engine' or 'a six-cylinder engine,' meaning the engine has that many of these parts.
From the word’s history
From Middle French cylindre, from Latin cylindrus, from Greek kýlindros, from kylíndō 'I roll'.
經拉丁文 cylindrus，源自希臘文「滾動」。
組成From Greek 'kylindein,' meaning to roll.
