non-algebraic function
  کریای ِ ناجبری   
karyâ-ye nâjabri

Fr.: fonction non algébrique   

A → transcendental function. Examples are: exponential, logarithmic, and trigonometric functions.

non-; → algebraic + → function.

non-baryonic dark matter
  ماده‌ی ِ سیاه ِ ناباریونی   
mâde-ye siyâh-e nâbâriyoni

Fr.: matière noire non-baryonique   

Dark matter composed of → non-baryonic particles.

non-; → baryonic; → dark; → matter.

non-baryonic matter
  مادّه‌ی ِ ناباریونی   
mâdde-ye nâbâriyoni (#)

Fr.: matière non-baryonique   

Matter that, unlike the ordinary matter, is not made of baryons (including the neutrons and protons). It is proposed as a possible constituent of dark matter.

non-; → baryonic matter.

non-coherent radiation
  تابش ِ ناهمدوس   
tâbeš-e nâhamdus (#)

Fr.: rayonnement incohrént   

Radiation having waves that are out of phase in space and/or time; radiation which is not → coherent.

non-; → coherent; → radiation.

non-contingent
  نا-آمرسان   
nâ-âmarsân

Fr.: non contingent   

Describing a → proposition that is either → true in every possible circumstance or → false in every possible circumstance. A proposition that is not → contingent.

non-; → contingent.

non-dispersive medium
  مدیم ِ ناپاشنده   
madim-e nâpâšandé

Fr.: milieu non dispersif   

A medium in which the → phase velocity is independent of frequency.

non-; → dispersive; → medium.

non-Euclidean geometry
  هندسه‌ی ِ نا-اقلیدوسی   
hendese-ye nâ-oqlidosi (#)

Fr.: géométrie non-euclidienne   

Any of several geometries which do not follow the postulates and results of Euclidean geometry. For example, in a non-Euclidean geometry through a point several lines can be drawn parallel to another line. Or, the sum of the interior angles of a triangle differs from 180 degrees. According to Einstein's general relativity theory, gravity distorts space into a non-Euclidean geometry.

non-; → Euclidean geometry.

non-hierarchical multiple system
  راژمان ِ بستایی ِ ناپایگانی   
râžmân-e bastâyi-ye nâpâygâni

Fr.: système multiple non hiérarchique   

A → multiple star system that lacks the characteristics of a → hierarchical multiple system.

non-; → hierarchical; → multiple; → system.

non-ideal magnetohydrodynamics (MHD)
  مغنات-و-هیدروتوانیک ِ نا-آرمانی، ~ نا-مینه‌وار   
meqnâtohidrotavânik-e nâ-ârmâni, ~ nâ-minevâr

Fr.: magnétohydrodynamique non idéale   

A → magnetohydrodynamics approach dealing with → plasmas which is an improvement with respect to → ideal magnetohydrodynamics. Non-ideal magnetohydrodynamics allows for a drift between particles, redistributing the → magnetic flux and acting on both the → angular momentum and magnetic flux conservation issues.

non-ideal; → magnetohydrodynamics.

non-inertial frame
  چارچوب ِ نالختی‌ناک، ~ نالختی‌مند   
cârcub-e nâlaxtinâk, ~ nâlaxtimand

Fr.: référentiel non inertiel, ~ non galiléen   

Any frame of reference in which the law of inertia does not apply, such as in accelerating and rotating frames. For example, the Earth is a non-inertial frame because it is rotating about its axis. But the rotation is so slow that the associated acceleration is negligible compared to other accelerations commonly encountered in everyday life. However, the non-inertial nature of the Earth appears in, e.g., the → Coriolis effect. → inertial reference frame.

non-; → inertial; → frame.

non-ionized
  نایونیده   
nâyonidé (#)

Fr.: non ionisé   

Not ionized, → neutral.

non-; → ionized.

non-radiative process
  فراروند ِ ناتابشی   
farâravand-e nâtâbeši

Fr.: processus non radiatif   

An process in which an excited state returns to the ground state without emitting radiation. → radiative process.

non-; → radiative; → process.

non-relativistic
  ناباز‌آنیگی‌مند   
nâ-bâzânigi-mand

Fr.: non-relativiste   

Not concerned with or based on the → theory of relativity. See also:
non-relativistic electron, → non-relativistic mechanics, → relativistic.

non-; → relativistic.
