responsivity pâsoxandegi Fr.: responsivité A performance criterion for an electronic detector, the ratio of the detector's electrical output to its optical input. → responsive; → -ity. |
rest âram Fr.: au repos Cessation or absence of motion. → rest energy; → rest mass. M.E.; O.E. ræste, reste "rest, bed, intermission of labor, mental peace," akin to O.H.G. rasta "league of miles," O.N. rost "league, distance after which one rests." Âram, variant of ârâm "rest, quiet, tranquility;" Mid.Pers. râm "peace," râmenidan "to give peace, pleasure," râmišn "peace, pleasure;" Av. ram- "to stay, rest;" cf. Skt. ram- "to stop, stand still, rest, become appeased;" Gk. erema "quietly, gently;" Goth. rimis "rest;" Lith. rãmas "rest." |
rest energy kâruž-e âram Fr.: énergie au repos The energy which a particle has when it is at rest. According to Einstein's → mass-energy relation, it is equal to the → rest mass times the square of the → speed of light: E = mc2. |
rest frame cârcub-e âram Fr.: référentiel au repos, repère ~ The → frame of reference with respect to which an object or observer is at rest. A clock in that particular rest frame registers what is by definition → proper time. See also → moving frame. |
rest mass jerm-e âram Fr.: masse au repos The → inertial mass that an object has when it is at rest relative to an observer. |
rest-mass energy kâruž-e jerm-e âram Fr.: énergie au repos Same as → rest energy. |
restoration bâzsâzi (#), bâzgardâneš Fr.: restauration The act or process of restoring such as → image restoration. Verbal noun of → restore. |
restore bâzsâxtan, bâzgardândan Fr.: restaurer 1) To bring back into existence, use, or the like; reestablish. M.E., from O.Fr. restorer, from L. restaurare "repair, rebuild, renew," from → re- "back, again" + -staurare, from PIE root *sta- "to stand, set down, make or be firm," → state. Bâzsâxtan, from bâz- "back, again," → re-, +
sâxtan "to build, make, fashion; to adapt, adjust, be fit" (from
Mid.Pers. sâxtan, sâz-, Manichean Parthian s'c'dn "to prepare,

restored image vine-ye bâzsâxté, tasvir-e ~ Fr.: image restaurée An image that has been upgraded by a process of → image restoration. Restored, p;p. of restore, → restoration; → image. Tasvir, → image; bâzsâxté, p.p. of bâzsâxtan, → restoration. |
restoring force niru-ye, bâzgardân, ~ bâzsâz Fr.: force de rappel A force that comes into play after a system is perturbed away from the equilibrium, tending to bring the system back the equilibrium position. For example, when a pendulum is displaced from its equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. The restoring force combined with the pendulum's mass causes it to oscillate about the equilibrium position. |
restrain bâzdâštan (#) Fr.: restreindre To hold back from action; keep in check; repress; to limit or hamper the activity, or effect of. M.E. restreynen, from O.Fr. restreindre "press, push together; curb, bridle;" from L. restringere "to draw back tightly, confine," from → re- "back" + stringere "draw tight," → strain. Bâzdâštan, from bâz- prefix denoting "reversal, opposition," → re-, + dâštan "to hold," → property. |
restrict forudâštan, forudâridan Fr.: restreindre To confine or keep within limits. → restricted three-body problem. From L. restrictus, p.p. of restringere "to restrict, bind fast, restrain," from → re- "back" + stringere "to draw tight." Forudâštan "to keep down, hold under control, bring to a halt" (Steingass, Dehxodâ),
from foru- "down, downward," → de-,
+ dâšt past stem of dâštan
"to have, to possess"
(Mid.Pers. dâštan; O.Pers./Av. root dar- "to hold, keep back,

Gk. thronos "elevated seat, throne;" L. firmus "firm, stable;"
Lith. daryti "to make;" PIE *dher- "to hold, support")
+ -an infinitive suffix. |
restricted three-body problem parâse-ye seh jesm-e forudâridé Fr.: problème restreint à trois corps A special case of the → three-body problem in which the → mass of one of the bodies is negligible compared to that of the two others. If the relative motion of the two massive components is a circle, the situation is referred to as the → circular restricted three-body problem. An example would be a space probe moving in the → gravitational fields of the → Earth and the → Moon, which revolve very nearly in circles about their common → center of mass. |
restriction forudâreš Fr.: restriction The act of restricting, the state or the condition of being restricted. |
result barâyé Fr.: résultat General: Something that happens as a consequence; outcome. M.E. resulten (v.); L. resultare "to result," in classical L.

Barâyé, literally "upcoming," from bar- "on; up; upon; in; into; at; forth; with; near; before; according to" (Mid.Pers. abar; O.Pers. upariy "above; over, upon, according to;" Av. upairi "above, over," upairi.zəma- "located above the earth;" cf.

resultant barâyand (#) Fr.: résultante Physics: The single vector obtained by applying vector addition to two or more given vectors. M.E., n. use of L. resultant-, pr.p. of resultare, → result. Barâyand, from bar, → result, + -âyand short for âyandé agent noun of âmadan "to come, arrive, become," → result. |
