Factors influencing the filtration performance of geotextile can be classified into four categories-external conditions(hydraulic gradient and loading state) ;(bio) chemical conditions of fluent(pH, hardness(e. g. [Fe], [Mn], [Mg], [Ca]), redox potential(Eh) for iron ochre, BOD and COD of water(substrate type/concentration), osmotic pressure and dissolved oxygen) ;the properties of basement material(coefficient of uniformity(Cu), coefficient of gradation(Cc), plastic index(PI), double hydrometer ratio(DHR) for dispersive clay, particle shape and grain hardness for granular soil, compaction degree of soil and saturation degree) ;and the properties of geotextile(filtration opening size(FOS), apparent opening size(AOS), fiber density, textile bulk density(mass/area), porosity, thickness and fiber material)... screen test results clearly indicated that the height of self filtration is proportional to the constriction size(Dc) of granular filter used. Additionally, they suggested the filter opening size value should be within the range between d50 and d80 for linearly graded soil and within the flat range in gap graded soil. 2, record 2, English, - opening%20size

Pour les géotextiles utilisés comme filtres, on mesurera par commodité la probabilité de passage des particules de sol d'un diamètre connu. On assimile ainsi le géotextile à un tamis. On enregistre la taille maximale des particules traversant le tamis, mesure assimilée à un diamètre, d'où l'expression «diamètre de filtration». Plusieurs principes et méthodes sont actuellement utilisés pour définir cette caractéristique : tamisage à sec de billes de verre calibrées [...]; tamisage à sec de particules de sol [...]; tamisage de sol à l'humide [...]; tamisage de sol sous régime hydrodynamique. 4, record 2, French, - ouverture%20de%20filtration

The ram profile is a record of a hardness index through a vertical section of the snowpack. The ram hardness(R) is measured by driving a ram penetrometer(ram or ramsonde) vertically into the snowpack. The ram is a tube or rod with a centimeter scale for depth and a standard cone-shaped tip. The operator drops a hammer(H) a certain distance(f) and records the penetration depth(p) of the ram into the snow. 6, record 3, English, - ram%20profile

The capacity [of a grinding mill] is directly affected by the grindability of the ore. Unfortunately, no fully acceptable definition of grindability has yet been agreed on. It includes the qualities of hardness(or brittleness) and toughness(resilient resistance) of the ore and the characteristic resulting particle shape of the finished product...

[...] F.C. Bond (1951) a publié, sous le nom de troisième théorie, un essai de justification mathématique de la position intermédiaire, rattachant l'énergie théoriquement nécessaire à la puissance 2,5 de la dimension. La théorie de Bond lui a permis de mettre au point une méthode de mesure de la broyabilité (ou aptitude au broyage) complétée par une formule de calcul de l'indice énergétique, dont l'emploi tend à devenir de plus en plus courant.
