Made of tubes, or shaped like a tube — long, round, and hollow in the middle. A tubular steel chair is one built from metal pipes; tubular bells are the hanging metal tubes an orchestra strikes; a worm has a tubular body.

Made of tubes由管子做成的, or shaped like a tube或形狀像管子 — long, round, and hollow in the middle長長的、圓圓的，中間是空心的. A tubular steel chair用金屬管做的椅子 is one built from metal pipes就是這樣做出來的; tubular bells管弦樂團敲的懸掛金屬管 are the hanging metal tubes an orchestra strikes就是這個; a worm has a tubular body蟲子則有著管狀的身體.

The word is common in describing furniture, machines, buildings and living things, and it is neutral and slightly technical — an engineer's or a designer's word rather than a chatty one. Hollow is the part students forget: if it is round but solid all through, like a pencil lead or a broom handle, 'cylindrical' is the better word.

The word這個字 is common in describing furniture, machines, buildings and living things常用來形容家具、機器、建築和生物, and it is neutral and slightly technical語感中性又有點技術性 — an engineer's or a designer's word比較像工程師或設計師會用的字 rather than a chatty one不是閒聊會講的. Hollow中空 is the part students forget是學生最容易忘記的重點: if it is round but solid all through如果整個是圓的但裡面是實心的, like a pencil lead or a broom handle像鉛筆芯或掃把柄, 'cylindrical' is the better word用「cylindrical」比較好.

There is also a slang sense worth knowing when you watch old films: in 1980s American surfing talk 'tubular' meant excellent, wonderful — a great wave curls over into a tube around the surfer, so the best waves were tubular. It sounds dated and comic now, the way 'radical' does.

There is also a slang sense worth knowing when you watch old films還有一個看老電影時該知道的俚語用法: in 1980s American surfing talk在1980年代美國衝浪的說法裡 'tubular' meant excellent, wonderful「tubular」是指很棒、很讚 — a great wave curls over into a tube around the surfer大浪捲起來會在衝浪者周圍形成一個管子, so the best waves were tubular所以最棒的浪就叫tubular. It現在講這個字 sounds dated and comic now聽起來很過時又有點好笑, the way 'radical' does就像「radical」一樣.
