Subject field(s)
  • Geophysics
DEF

A field that satisfies the Laplace equation.

CONT

The deconvolution of gravity or magnetic data requires the separation of two basic components of the potential fields: one component represents a basic irreducible wave form or signature of the potential field, and the other represents the position and scale or distribution of this wave form throughout the area of measurement.

OBS

The Laplace equation is equivalent in three dimensions to the inverse square law of gravitational or electrical attraction (in source-free regions; in regions with sources, it becomes Poisson's equation). Examples of potential fields include the field of the gravity potential and static electric and magnetic fields.

OBS

potential field: term used at Natural Resources Canada - Earth Sciences Sector.

  • Géophysique
CONT

La déconvolution des données de la gravité ou magnétiques requiert une séparation de deux composantes de base des champs potentiels : une composante représente une forme d'onde de base irréductible ou la signature du champ potentiel, tandis que l'autre représente la position et l'échelle ou la distribution de la forme d'onde de toute la région mesurée.

OBS

champ potentiel; champ de potentiel : termes en usage à Ressources naturelles Canada - Secteur des sciences de la Terre.
