Definition of helix in English:

helix

nounPlural helices ˈhiːlɪksˈhilɪks

1An object having a three-dimensional shape like that of a wire wound uniformly in a single layer around a cylinder or cone, as in a corkscrew or spiral staircase.
螺旋，螺旋状物
Example sentencesExamples
- Terrified, he ran to a stairwell; its helix curved upward toward the floors above.
- A television monitor showed what was inside: a glowing ball of gas surrounded by a metal helix.
- The building blocks are chosen so that the ribbon curls into a helix.
- Seven of the predicted helices in our final structure are consistent with the model of MacDonald.
- They found that DNA consists of two connected twisted strands in the shape of a helix.
- The crucial trick is that the helix is not even: it has a significantly larger diameter in the middle than at the ends.
- He was looking at the picture of the helix.
- Both had almost the same number of helices, strands and turns.
- It described his proposal for a different type of helical structure, which he called the helix.
- The excess is carefully cut away to fabricate the helix shape.
- The fibers themselves are assumed to be straight helices.
- Although Concrete art is typically austerely geometrical, it is not necessarily so; Bill's sculpture, for example, often uses graceful spiral or helix shapes.
