bâzsâzi (#), bâzgardâneš
The act or process of restoring such as → image restoration.
Verbal noun of → restore.
1) To bring back into existence, use, or the like; reestablish.
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,

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.
To hold back from action; keep in check; repress; to limit or hamper the activity, or effect of.
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."

"to have, to possess"
(Mid.Pers. dâštan; O.Pers./Av. root dar- "to hold, keep back,
maintain, keep in mind;" cf. Skt. dhr-, dharma- "law;"
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.
The act of restricting, the state or the condition of being restricted.
General: Something that happens as a consequence; outcome.
