anisotropic homogeneous cosmological model model-e keyhânšenâxti-ye hamgen o nâ-izogard Fr.: modèle cosmiologique homogène mais anisotrope A solution to Einstein's theory of → general relativity that is spatially homogeneous but allows for rotation and/or shear. See also → Bianchi cosmological model. → anisotropic; → homogeneous; → cosmological; → model. |
homogeneous hamgen (#) Fr.: homogène 1) Of uniform composition or having a common property throughout. Homogeneous, from M.L. homogeneus, from Gk. homogenes "of the same kind," from homos "same," → homo-, + genos "race, kind," gonos "birth, offspring," from PIE base *gen-/*gon-/*gn- "to produce, beget, be born," cf. Av. zan- "to bear, give birth to a child, be born," infinitive zazāite, zāta- "born," zana- "race" (in sruuô.zana- "belonging to the race of the horned ones"), O.Pers. zana- "tribe" (in paru-zana- "consisting of many tribes"), Skt. janati "begets, bears," jana- "creature, human being, race, tribe, people;" L. genus "race, stock, kind," gignere "to beget." Hamgen "of the same kind, like each other; friend, partner," from ham-, → homo-, + gen "kind," O.Pers./Av. zana- "race; tribe," cognate with L. genus, as above). Alternatively, gen may be a variant of Mid./Mod.Pers. gôn/gun "kind, type; manner; color, skin color," from Av. gaona- "hair, hair color, color." |
homogeneous fluid šârre-ye hamgen (#) Fr.: fluide homogène A fluid with uniform properties throughout, but meteorologists sometimes designate as homogeneous a fluid with constant density. → homogeneous, → fluid. |
homogeneous linear differential equation hamugeš-e degarsâne-yi-ye xatti hamgen Fr.: équation différentielle linéaire homogène A → linear differential equation if the right-hand member is zero, Q(x) = 0, on interval I. → homogeneous; → linear; → differential; → equation. |
homogeneous turbulence âšubnâki-ye hamgen (#) Fr.: turbulence homogène → Turbulence in which spatial derivatives of all mean turbulent quantities are negligible. → homogeneous, → turbulence. |
homogeneous Universe giti-ye hamgen (#) Fr.: Univers homogène A model Universe which is homogeneous and → isotropic on large scales. It is modeled by a → Robertson-Walker cosmology. A homogeneous Universe is filled with a constant density and negligible pressure. Any small spatial region is characteristic for the whole Universe. → homogeneous; → Universe. |
inhomogeneous nâhamgen (#) Fr.: inhomogène Lack of homogeneity; something that is not → homogeneous. → in- "not" + → homogeneous. |
nonhomogeneous nâhamgen (#) Fr.: non homogène Not homogeneous. → nonhomogeneous linear differential equation. → non-; → homogeneous. |
nonhomogeneous linear differential equation hamugeš-e degarsâne-yi-ye xatti nâhamgen Fr.: équation différentielle linéaire non homogène A → linear differential equation if Q(x)≠ 0 on interval I. → nonhomogeneous; → linear; → differential; → equation. |
