DEF

Hauteur de la couche d'ozone si celle-ci était rabattue au sol, dans une colonne atmosphérique verticale, à pression et température normales.

OBS

La couche d'ozone qui protège la vie sur Terre, bien que concentrée à vingt-cinq kilomètres d'altitude, est constituée de molécules d'ozone inégalement réparties dans l'atmosphère. C'est donc uniquement par métaphore qu'on peut parler d'épaisseur de la couche d'ozone. Physiquement, on peut cependant mesurer la quantité de molécules d'ozone au-dessus d'un point donné et en déduire une certaine épaisseur.

Spanish

Campo(s) temático(s)
  • Contaminación del aire
OBS

La Fundación del Español Urgente (Fundéu BBVA), con el asesoramiento de la Real Academia Española, indica que la expresión capa de ozono, que alude a una zona de la atmósfera que filtra las radiaciones nocivas del Sol, se escribe íntegramente en minúscula. [...] Dado que se trata de un nombre descriptivo de una región de la atmósfera donde aumenta la concentración de ozono, no hay razón para escribirlo con mayúscula, como tampoco se hace con las denominaciones de otras capas como la ionosfera o la estratosfera. [...] Asimismo, ozono se escribe con minúscula inicial por tratarse de una sustancia química, igual que el agua, el amoniaco o el metano, de modo que en los ejemplos anteriores lo apropiado habría sido capa de ozono o, como denominación alternativa pero más técnica, ozonosfera.

cokes: The standard grades of hot-dipped tinplates, that carry about 0.56 kg of tin per basis box (i.e. lighter coating than the charcoal grades), that consist of mild-steel coated with tin, and that are used for packaging, canning and general purposes.

CONT

Various grades of hot-dipped tin plate were produced, the terminology indicating in a general way the weight of tin coating or, more exactly, the amount of tin used to produce the given unit or base box of plate. Coke tin plate has always designated the plate produced with the lowest amount of tin and formerly was called Cokes or Common Cokes. In ascending weight of coating, the various grades were Common Cokes, Standard Cokes, Best Cokes, and Kanners Special. Charcoal tin plate carries still heavier coatings including 1A and 2A.

CONT

Terms, charcoal plate and coke plate, which in last century described quality of iron used as a base metal, have now come to be applied to tin plate of certain coating thickness. Amount of coating on coke plates is generally between 1.24 and 2.5 pounds per base box - on charcoal plates between 3 pounds and 5 pounds per base box. For roofing applications, heavier charcoal weight coatings have always been preferred. Common cokes, 1.25 lb/base box. Standard cokes, 1.50 lb/base box; Best cokes, 1.70 lb/base box. "Kanners" special cokes, 2.0 lb/base box. ... Weight of coating on an electrolytic plate is a measurement of amount of coating on both sides of sheet, expressed in grams per square meter. Prior to adoption of this system, a "pot yield" method was used. The coating designation numbers are a hold over from this earlier system.

  • Meteorological Forecasting, Data Measurement and Analysis
  • Atmospheric Physics
DEF

Thickness h of the layer in which mixing occurs with a nearly adiabatic temperature gradient and only light winds.

CONT

Mixing Layer Depth ... The mixing layer is the atmospheric zone near the surface where pollutants disperse rapidly. The depth of this layer depends on the temperature and on the stability of the atmosphere at low levels. Lower values of mixing layer depth indicate that the pollutants will be mixed in a smaller volume of air.

OBS

The mixing height is the depth of the unstable air in the boundary layer and is used for forecasting smoke or pollutant trajectories.

OBS

h is approximately equal to kL, where k is the von Kármán constant and L, the Monin-Obukhov length.

Key term(s)

CONT

Épaisseur de la couche de mélange [...] La couche de mélange est la portion de l'atmosphère près de la surface où les polluants se dispersent rapidement. L'épaisseur de cette couche dépend de la température et de la stabilité de l'atmosphère dans les bas niveaux. De faibles valeurs d'épaisseur de la couche de mélange signifient que les polluants seront dilués dans un volume d'air moindre.

OBS

La «hauteur» est une dimension d'un corps observé à la verticale (i.e. de bas en haut); l'«épaisseur» lorsque regardée à la verticale peut parfois être considérée comme la «hauteur».

Minimized life-cycle cost and optimal retrofit strategies for Multi-family residences ... This paper only will deal with the insulation measures and how they will emerge if the minimized LCC [life-cycle cost] concept is implemented. In [2] we have shown the influence of different discount rates, optimization periods, building and energy costs etc, on the optimal insulation thickness, but no concern was taken to the fact that the insulation thickness will influence the proper heating equipment.

CONT

An investigation of the thermal conductivity of pipe insulations will explore various types of insulation as well as the effect of insulation thickness on preventing energy loss. We will collect data relating to temperature distributions along pipes and through their insulations, at elevated temperatures.

Subject field(s)
  • Electrochemistry
OBS

When a kinetic current flows, the concentrations of the electroactive substance B and its precursor C at very small distances from the electrode surface are influenced both by mass transfer and by the finite rate of establishment of the chemical equilibrium. As the distance from the electrode surface increases, the chemical equilibrium is more and more nearly attained. The thickness of the reaction layer is the distance from the electrode surface beyond which deviations from the chemical equilibrium between C and B are taken to be negligibly small.

French

Domaine(s)
  • Électrochimie
OBS

Lorsqu'un courant cinétique circule, les concentrations de la substance électroactive B et de son précurseur qui sont présentes à de très faibles distances de la surface de l'électrode sont influencées à la fois par le transfert de masse et par la vitesse finie à laquelle l'équilibre chimique s'établit. À mesure que l'on s'éloigne de l'électrode, on s'approche pratiquement de l'équilibre chimique. L'épaisseur de la couche réactionnelle est la distance de l'électrode au-delà de laquelle on considère que les écarts, par rapport à l'équilibre chimique, entre B et C sont négligeables.
