Definition of helicoid in English:

helicoid

noun ˈhiːlɪkɔɪdˈhɛləˌkɔɪd

1A helical or spiral object.
Example sentencesExamples
- If the disk's surface curved a lot, the disk could arrange itself only one way - as a double spiral staircase like a helicoid.
1. 1.1Geometry A surface formed by simultaneously moving a straight line along an axis and rotating it around it (like a screw thread).
  〔几何〕螺旋面
  Example sentencesExamples
  One of the clues that a helicoid is an efficient surface and not just an accident is its ubiquity in nature.

adjective ˈhiːlɪkɔɪdˈhɛləˌkɔɪd

Of the form of a helix or helicoid.
螺旋形的，螺旋面的
Example sentencesExamples
- Arthropod cuticle can produce unusual optical effects, analogous to solutions of liquid crystals, resulting from a layered, helicoid structure.
- Molecules may knit together to form helicoid surfaces, emblems of stable energy states.
- The pin count for that cooler was 371 helicoid pins.
- There are helicoid pins fitted into the base, which addresses the heat dissipation weakness of copper.
- This new helicoid pin design increases surface area for heat dissipation.
Synonyms
coiled, helical, helix-shaped, corkscrew, curling, winding, twisting, whorled, scrolled

Derivatives

helicoidal

adjective hiːlɪˈkɔɪd(ə)lˈhɛləˌkɔɪd(ə)l

The energy is expressed in terms of the six helicoidal parameters: twist, tilt, roll, shift, slide, and rise.
Example sentencesExamples
- Thirteen pages with drawings for man-powered aeroplanes survive and there is one design for a helicoidal helicopter.
- The pattern of currents was originally represented as a spiral or helicoidal flow, but more complex cells of circulation have since been identified which can influence the distribution of erosion and deposition.
- One could pursue this type of analysis further and compute, for example, the correlations between two different helicoidal parameters in different steps, etc.
- Each inflorescence produces 200-300 flowers that have a helicoidal repartition and open in sequence from bottom to top.

Origin

Late 17th century: from Greek helikoeidēs 'of spiral form', from helix, helik- (see helix).
