n.蠟燭芯；燈芯

It was empty, but a feeble tallow candle, with a broken back and a long, cauliflower-headed wick sputtered upon the table. 房間是空空洞洞的，只點(diǎn)了一支暗淡無(wú)光的牛脂蠟燭，背部開(kāi)裂，蠟燭芯長(zhǎng)長(zhǎng)的，花椰菜頭似的，蠟燭油濺潑在桌子上。

A wick connects it to a reservoir. 一燈芯繩把它與水槽相連。

The wick is the quintessence of the candle. 燈芯是蠟燭的精華。
