Record 2 1997-08-20

English

Subject field(s)
  • Scientific Measurements and Analyses
  • Geology
DEF

The degree of abrasion of a clastic particle as shown by the sharpness of its edges and corners, expressed by Wadell (1932) as the ratio of the average radius of curvature of the several edges or corners of the particle to the radius of curvature of the maximum inscribed sphere (or to one-half the nominal diameter of the particle).

CONT

... roundness may be defined as the ratio of the average radius of curvature of the corners of the particle "image" to the radius of the maximum inscribed circle.

French

Domaine(s)
  • Mesures et analyse (Sciences)
  • Géologie
CONT

[...] un cube aurait un émoussé nul et une sphéricité forte, tandis qu'un cylindre terminé par deux hémisphères aurait une sphéricité nulle et un émoussé élevé.

CONT

[...] l'émoussé des grains de sable peut être évalué à la loupe binoculaire à l'aide d'un micromètre-cible.

OBS

Il faut distinguer entre forme (sphéricité) et arrondi («roundness»). L'arrondi résulte de l'usure des bords et des coins, tandis que la forme n'a rien à faire avec l'allure des bords et des coins [...]

Record 3 1993-11-08

English

Subject field(s)
  • Winemaking
CONT

to be round, a wine must be harmonious but also big. It will be in perfect balance, and it gives a sense of "roundness" in the way it fills the mouth.

French

Domaine(s)
  • Industrie vinicole
OBS

un vin qui possède cette qualité est un vin toujours très agréable. Suffisamment riche en alcool et en glycérine, il ne possède pas une acidité prononcée [donne l'impression d'être franc, loyal].
