Pârsang "a make-weight," from pâr-, a variant of pâd-, → counter-, + sang a variant of sanj, sanjidan "to measure; compare, put in balance," → object; alternatively, pârsang "a piece of stone," from pâr, short for pâré "piece, part," + sang, → stone, meaning "weight." |
eight hašt (#) Fr.: huit A → cardinal number between → seven and → nine. M.E. eighte, from O.E. eahta, æhta, related to O.Norse atta, Swed. åtta, Du. acht, O.H.G. Ahto, Ger. acht; Pars. hašt, as below, from PIE *okto(u) "eight." Hašt, from Mid.Pers. hašt; Av. ašta; cognate with Skt. asta; Gk. okto; L. octo (from which It. otto, Sp. ocho, Fr. huit). |
height bolandi (#), bolandâ (#), farâzâ (#) Fr.: hauteur Distance upward from a given level to a fixed point. M.E., from O.E. hiehthu; → high + -th a suffix forming nouns of action (e.g., birth) or abstract nouns denoting quality or condition (depth; length; warmth). Bolandi, bolandâ "height," noun forms from boland
"high," variants bâlâ
"up, above, high, elevated, height," borz "height, magnitude"
(it occurs also in the name of the mountain chain Alborz),
Lori dialect berg "hill, mountain;"
Mid.Pers. buland "high;" O.Pers. baršan- "height;"
Av. barəz- "high, mount," barezan- "height;" cf.
Skt. bhrant- "high;" L. fortis "strong" (Fr. & E. force);
O.E. burg, burh "castle, fortified place," from P.Gmc.
*burgs "fortress;" Ger. Burg "castle," Goth. baurgs "city,"
E. burg, borough, Fr. bourgeois, bourgeoisie, faubourg);
PIE base *bhergh- "high." |
makeweight pârsang (#) Fr.: contrepoids Something put in a scale to complete a required weight. Pârsang, → counterweight. |
mean molecular weight vazn-e molekuli-ye miyângin (#) Fr.: poids moléculaire moyen The total atomic or molecular weight divided by the total number of particles. For instance, the mean molecular weight of a plasma of pure ionized ^{4}He would be 4 (the atomic mass number) divided by 3, the total number of particles (1 nucleus plus 2 electrons), i.e. 4/3. |
molecular weight vazn-e molekuli (#) Fr.: poids moléculaire The sum of the atomic weights of all the atoms in a molecule. |
pressure scale height bolandi-ye marpel-e fešâr Fr.: hauteur d'échelle de pression A basic ingredient of the → mixing length theory that scales with the → mixing length. It is defined by the relation: H_{P} = -dr/dln P = -Pdr/dP , where r is the height and P the pressure. See also → scale height. |
scale height bolandi-ye marpel Fr.: hauteur d'échelle The height within which some parameter, such as pressure or density, decreases by a factor of e. For example, an atmospheric scale height of 100 km means that the value at 100 km is 1/e the value at the surface. |
statistical weight vazn-e âmâri Fr.: poids statistique 1) Statistics: A number assigned to each value or range of values of a
given quantity, giving the number of times this value or range of
values is found to be observed. → statistical; → weight. |
weight vazn (#) Fr.: poids 1) The force of attraction of the Earth on a given mass.
→ molecular weight; → weightlessness. M.E., from O.E. gewiht, cf. O.N. vætt, O.Fris. wicht, M.Du. gewicht, Ger. Gewicht. Vazn, loan from Ar. wazn. |
weight concentration dabzeš-e vazni Fr.: concentration en poids of a gas included in the composition of a → gas mixture, the ratio of mass of this gas to the mass of the whole mixture. Same as → weight fraction and → weight-fraction concentration. → weight; → concentration. |
weight fraction barxe-ye vazni Fr.: fraction en poids Same as → weight concentration. |
weight of a tensor density vazn-e cagâli-ye tânsor Fr.: poids d'une densité de tenseur A constant the value of which is characteristic for any given → tensor density. |
weight-fraction concentration barxe-ye vazni-ye dabzeš Fr.: concentration en poids Same as → weight concentration. → weight; → fraction; → concentration. |
weighted mean miyângin-e vazni (#) Fr.: moyenne pondérée An mean which is obtained by combining different numbers according to the relative importance of each. |
weightlessness bivazni (#) Fr.: apesanteur The phenomenon experienced by a body when there is no force of reaction on it. This happens when the body is in → free fall in a → gravitational field or when the net force on it is zero. From → weight + -less suffix meaning "without" + -ness a suffix of quality or state. |
