isotopic fractionation barxâneš-e izotopi Fr.: fractionnement isotopique Same as → isotope fractionation. → isotopic; → fractionation |
isotopic number adad-e izotopi Fr.: nombre isotopique The difference between the number of neutrons in an isotope and the number of protons. Neutron excess. |
isotopic ratio vâbar-e izotopi Fr.: rapport isotopique The relative abundances of two isotopes of a given chemical element, such as D/H (deuterium/hydrogen), (carbon) 12C/13C, and (uranium) 235U/238U. |
isotopic spin spin-e izotopi (#), izospin (#) Fr.: spin isotopique Same as → isospin. |
isotopologue izotopolog Fr.: isotopologue Any of molecular entities which differ in their isotopic composition but retain the same → chemical elements, e.g. H2O and HDO. |
isotopomer izotopomer Fr.: isotopomère Any of → isomers having the same number of each isotopic atom but differing in their positions. For example, CH3CHDCH3 and CH3CH2CH2D are a pair of isotopomers. Short for isotopic isomers. |
isotropic izogard, hamsângard (#) Fr.: isotrope Having physical properties that do not vary with direction. |
isotropic Universe giti-ye izogard, ~ hamsângard (#) Fr.: Univers isotrope A Universe having observed properties that appear identical in every direction. |
isotropy izogardi, hamsângardi (#) Fr.: isotropie The property by which physical properties are equal along all directions. → anisotropy. Isotropy, noun of → isotropic. |
issue 1) borunây; 2) borunâyidan Fr.: issue, question, problème 1a) A result or outcome of something. M.E., from O.Fr. issue "a way out, a going out, exit; final event," from L. exire "to go out, go forth; become public; flow, pour forth," from → ex- "out," + ire "to go," Borunây, literally "what comes out, exits," from borun, → out, + ây- present stem of âmadan "to come, arrive, become," → precession. |
iterate itaridan Fr.: itérer 1) To utter or to do something over again or repeatedly.
→ repeat. Iterate "to do again, repeat," back-formation from iteration, from L. iterationem (nom. iteratio) "repetition," noun of action from iterare "to do again, repeat," from iterum "again, for the second time;" cf. Skt. itara- "the other (of the two), another." Itaridan, from L. iter(um), Skt. itar(a-), as above, and Pers. dialects Kâšâni (Voništun) târ "the other;" Kurd. tir "the other" + -idan Pers. infinitive suffix. |
iteration itareš Fr.: itération A computational process involving a succession of approximations, which consists of repeating the operation by inputting the outcome of each preceding operation to improve the final result until a desired accuracy is achieved. Compare → repetition. Verbal noun of → iterate. |
iterative method raveš-e itareši Fr.: méthode itérative A method of computation in mathematics using → iteration. Iterative, characterized by or involving → iteration; → method. |
