absorption band bând-e daršami Fr.: bande d'absorption 1) A series of very closely spaced absorption lines in stellar spectra
resulting from the absorption of light by molecules. Bands caused by
titanium oxide (→ TiO bands) and carbon compounds occur
in the spectra of low temperature M and C stars. → absorption; → band. |
absorption coefficient hamgar-e daršam Fr.: coefficient d'absorption The fraction of normally incident light that is absorbed per unit path length or by a unit mass of absorbing medium. → absorption; → coefficient. |
absorption curve xam-e daršam Fr.: courbe d'absorption A graphic representation of the amount of radiant energy absorbed by a material as a function of the wavelength. → absorption; → curve. |
absorption feature ârang-e daršam Fr.: motif d'absorption A dip in a spectrum indicating that light has been absorbed on the path from the emitting source to the observer. It may be a line, corresponding to a well-defined atomic or molecular transition, or a more complex feature whose physical origin is not necessarily understood. → absorption; → feature. |
absorption line xatt-e daršami Fr.: raie d'absorption A dark line in the spectrum of a source produced by a lower temperature gas cloud lying between the source and the observer. → absorption; → line. |
absorption nebula miq-e daršami Fr.: nébuleuse par absorption, nébuleuse obscure A dark cloud of dust and gas that absorbs light from and impedes the view of background stars; dark nebula. → absorption; → nebula. |
absorption spectrum binâb-e daršami Fr.: spectre d'absorption A spectrum of absorption lines or bands, produced when light from a hot source, itself producing a continuous spectrum, passes through a cooler gas. → absorption; → spectrum. |
absorptivity daršamâyi Fr.: absorptivité The ratio of energy absorbed by a body to energy incident upon the same body. Absorptivity, from absorptive adj. from → absorb + → -ity, suffix expressing state or condition. Daršamâyi, from daršamâ quality adj. from daršam, present stem of daršamidan + -yi noun suffix. |
absorptivity-emissivity ratio vâbar-e daršamâyi/gosilâyi Fr.: rapport absorptivité-émissivité For a spatial object, the ratio between its absorption of solar radiation and its infrared emission. → absorptivity; → emissivity; → ratio. |
abstain parhizidan, parhiz kardan Fr.: s'abstenir To keep oneself from doing or partaking of something; refrain. → avoid. M.E. absteynen, absteinen, abstenen, from O.Fr. abstiner, abstenir, astenir "hold (oneself) back, refrain voluntarily," from L. abstinere / abstenere "withhold, keep back," from → ab-"off, away from" + tenere "to hold," from PIE root *ten- "to stretch," → tension. Parhiz, from Mid.Pers. pahrêzidan, pahrêxtan "to keep away from, abstain," ultimately from Proto-Ir. *pati-raic-, from prefix *pati- + *raic- "to leave, let abandon;" cf. Av. raēc- "to leave, let;" Pers. (+ *ui-) gorêz-, goriz-, gorixtan "to run away, flee;" Skt. rec- "to leave, release;" Gk. leipo "I let;" L. linquô "I leave;" PIE base *leikw- "to leave, let." |
abstinence parhiz (#) Fr.: abstinence The act or practice of abstaining from indulging a desire or appetite. Verbal noun of → abstain. |
abstract 1) âhanjidé (#); 2) âhanjidé (#), cekidé (#) Fr.: 1) abstrait; 2) abstrait, sommaire 1a) (adj.) A designation of what derives from → abstraction.
Contrasted to → concrete. M.E., from L. abstractus "drawn away," p.p. of abstrahere "to draw away, withdraw," from abs- "away," from → ab- + trahere "to draw," → attract. 1) Âhanjidé, p.p. of âhanjidan, variants âhixtan, âxtan
"to draw, pull, extract," → object. |
abstract object barâxt-e âhanjidé Fr.: objet abstrait An entity that does not exist in space or time and is not perceptible. Some examples are universals, sets, geometrical figures, and numbers. |
abstraction âhanješ (#) Fr.: abstraction 1) The mental process in which an element or quality is separated from a
total object. Also the result of this process. |
abstraction reaction vâžireš-e âhanješ (#) Fr.: réaction d'abstraction Chemistry: A bimolecular chemical reaction that involves removal of an atom or ion from a molecule. For example, hydrogen abstraction from methane: CH4 + Cl → CH3 + HCl. → abstraction; → reaction. |
absurd yâvé (#) Fr.: absurde Ridiculously senseless, illogical, or untrue; contrary to all reason. → reductio ad absurdum, → absurdity. See also → nonsense. M.Fr. absurde, from L. absurdus "out of tune; foolish," from surdus "deaf, stupid, inaudible." Yâvé, literally "unrelated speech," ultimately from *ui-vaka-, from *ui- "apart, away," → transit, + *vaka- "word, speech," → word. |
absurdity yâvegi (#) Fr.: absurdité The quality or state of being absurd; something that is absurd. |
abundance farâvâni (#) Fr.: abondance 1) The relative amount of a given → chemical element
with respect to other elements. M.E., from O.Fr. abundance, from L. abundantia "fullness," from abundare "to overflow," from L. → ab- "away" + undare "to surge," from unda "water, wave." Farâvâni "abundance," from farâvân "abundant," from feré "much, more; increase; priority;" Mid.Pers. frêh "more, much;" O.Pers. fra- "before, forth;" Av. frā, fərrā "forth, forward;" PIE base *pro-; cf. L. pro "on behalf of, in place of, before, for;" Gk. pro- "before, in front of." |
academic farhangestânik Fr.: académique 1) Of or relating to a college, academy, school, or other educational institution,
especially one for higher education. |
academician farhangestânvand Fr.: académicien A member of an association or institution for the advancement of arts, sciences, or letters. From Fr. académicien, from académic-, → academic, + -ian a suffix forming adjectives and nouns. Farhangestânvand, from farhangestân, → academy, + -vand a suffix forming adjectives and agent nouns, → actual. |
