Определение perturbation в Английский Язык Турецкий язык словарь
(Askeri) DÜZENSİZLİK (HV. ): Bir gök cisminin muntazam hareketinde, bu harekete amil olan kuvvet dışında bir kuvvetin sebep olduğu düzensizlik. Gezegenlerde bu hale, karşılıklı çekim kuvvetleri sebebiyet verir. Gazetelerde periyodik düzensizlik, mukabil durumlarına göre kısa süreli salınımlar; yüzyıllara bağlı düzensizlik ise yörüngelerindeki cüzi değişikliklerdir

(Tekstil) In astronomy, perturbation is the complex motion of a massive body subject to forces other than the gravitational attraction of a single other massive body
For a body orbiting the Sun or a planet, the gravitational effect of a third body (e g ,another planet) on its orbit, usually resulting in small changes or periodic fluctuations [For comets, outgassing near the sun may also act on its orbit ]
A disturbance in the regular elliptic or other motion of a heavenly body, produced by some force additional to that which causes its regular motion; as, the perturbations of the planets are caused by their attraction on each other
1 Any departure introduced into an assumed steady state of a system, or a small departure from a nominal path such as a desired trajectory Usually used as equivalent to small perturbation
A forced change to a system This can result in a sudden shift to a new state, an immediate return to the old state or a long transient resulting in one or the other
A method of reducing degeneracy by adding or subtracting small tolerances to costs, matrix elements, right-hand side elements, or bounds
To disrupt greatly; to agitate Variation in a designated orbit, as of an electron or planet, resulting from the influence of one or more external bodies
A perturbation is a small change in the movement, quality, or behaviour of something, especially an unusual change. perturbations in Jupiter's gravitational field
The deviation of an orbiting object from its path around a center of farce caused by the action of an additional center of force
Perturbation is worry caused by some event. This message caused perturbation in the Middle East Headquarters. = alarm
An imprecise term that means changing some parameter value (or function) and seeing what effect this has on the solution This embodies continuity and differentiability properties of the optimal responses: objective value, policy set, and perhaps dual values too This is what is sometimes called marginal analysis of solutions, and changes are limited to some neighborhood of the initial values Some use perturbation function to mean the optimal objective value, even for large changes in the parameters, as in parametric programming
an unhappy and worried mental state; "there was too much anger and disturbance"; "she didn't realize the upset she caused me"
a disposition that is confused or nervous and upset activity that is an intrusion or interruption; "he looked around for the source of the disturbance"; "there was a disturbance of neural function"
throw into great confusion or disorder; disturb in mind or make uneasy or cause to be worried or alarmed; "She was rather perturbed by the news that her father was seriously ill"
cause a celestial body to deviate from a theoretically regular orbital motion, especially as a result of interposed or extraordinary gravitational pull; "The orbits of these stars were perturbed by the passings of a comet"
Gravitational influences ("tugging" and "pulling") of one astronomical body on another Comets are strongly perturbed by the gravitational forces of the major planets, particularly by the largest planet, Jupiter These perturbations must be allowed for in orbit computations, and they lead to what are known as "osculating elements" (which means that the orbital element numbers change from day to day and month to month due to continued perturbations by the major planets, so that an epoch is necessarily stated to denote the particular date that the elements are valid
small adjustments made to the Keplerian model of a satellite's orbit; due to Earth's gravity and drag, a satellite's orbit is not a perfect ellipse of constant shape and orientation
Minor corrections to the Keplerian model of a satellite orbit as an ellipse of constant shape and orientation Since satellite orbits are affected by Earth's gravity and drag caused by the Earth's atmosphere (causing satellites to spiral downward), minor adjustments must be made to the orbit
