Subject field(s)
  • Scientific Measurements and Analyses

Universal entry(ies)
Mapp
symbol, see observation
DEF

The molar mass calculated from experimental data without the application of appropriate corrections ...

OBS

Its value would therefore not take into account corrections such as finite polymer concentration, association, preferential solvation, compositional heterogeneity or constitutional heterogeneity.

OBS

Mapp: In the symbol, the capital letter "M" is italicized, and the letters "app" are written in subscript (Mapp).

OBS

apparent molar mass; apparent relative molecular mass; Mapp: terms and symbol standardized by the International Organization for Standardization (ISO).

Mapp
symbol, see observation
DEF

Masse molaire calculée à partir de résultats expérimentaux sans appliquer les corrections pertinentes [...]

OBS

Sa valeur ne tiendrait donc pas compte, par exemple, de la concentration du polymère fini, des associations, de la solvation la plus appropriée, de l’hétérogénéité du composé ou de celle des constituants.

OBS

Mapp : Dans le symbole, la lettre majuscule «M» s'écrit en italique, et les lettres «app» s'écrivent en indice (Mapp).

OBS

masse molaire apparente; masse moléculaire relative apparente; Mapp : termes et symbole normalisés par l'Organisation internationale de normalisation (ISO).

DEF

Masa molar calculada a partir de datos experimentales sin aplicación de correcciones apropiadas, como para concentración de polímero finito, asociación, solvatación preferencial, heterogeneidad en la composición o en la constitución.

English

Subject field(s)
  • Radar, Radio Guidance and Goniometry
  • Spacecraft
  • Remote Sensing
DEF

[A technique] that corrects and improves radiometric values of individual pixels.

CONT

By using adaptive filters a compromise exists between the radiometric enhancement in the homogeneous areas and the preservation of the spatial resolution within the heterogeneous areas(i. e., the textural area or edges). Depending on the local heterogeneity degree of the target, pixels are weighted with a value ranging from the local mean to the raw intensity values.

OBS

radiometric enhancement: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

French

Domaine(s)
  • Radar, radioguidage et radiogoniométrie
  • Engins spatiaux
  • Télédétection
DEF

Technique qui corrige et améliore les valeurs radiométriques des pixels individuels.

OBS

accentuation radiométrique : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).
