A helix is a line that turns around a centre as it goes up or down, like a spring, a screw, or a staircase that climbs while it turns.

A helix helix是 a line一條線 that turns around a centre繞著中心轉 as it goes up or down一邊往上或往下走 like a spring, a screw, or a staircase that climbs while it turns就像彈簧、螺絲，或是一邊往上爬一邊轉的樓梯

DNA, the long code inside living things, is often shown as a double helix: two of these lines twisting together. Doctors also call the outer curved edge of the ear the helix. There is a much rarer verb, to helix, meaning to twist into this shape or to move in that climbing turn.

DNA DNA the long code inside living things也就是生物體內那條很長的密碼 is often shown as a double helix常常被畫成double helix（雙螺旋） two of these lines twisting together兩條這樣的線纏繞在一起 Doctors醫生 also call也把 the outer curved edge of the ear耳朵外緣那道彎彎的邊 the helix叫做helix（耳輪） There is還有 a much rarer verb一個很少見的動詞 to helix to helix meaning意思是 to twist into this shape扭轉成這個形狀 or to move in that climbing turn或以那種一邊爬升一邊轉的方式移動

Though actually, people often say spiral for both a flat coil and this climbing shape; a true helix keeps rising or falling as it turns, like a screw. It is not the same picture as a circle lying flat.

Though actually不過其實 people人們 often say spiral常常把spiral用 for both a flat coil在平面的圈圈 and this climbing shape和這種爬升的形狀上 a true helix真正的helix keeps rising or falling as it turns會一邊轉一邊持續往上升或往下降 like a screw就像螺絲一樣 It它 is not the same picture as a circle lying flat跟平躺著的圓圈畫面不一樣
