  ۱، ۲) کرینی؛ ۳) نامنشیی   
1, 2) karini; 3) nâmeneši

Fr.: nominatif   

1) → nominative case.
2) Similar to such a case in function or meaning.
3) Made out in a person's name (

From L. nominativus "belonging to naming," from nomen, → name.

Karini, relating to or denoting karin, → subject.

nominative case
  کاته‌ی ِ کرینی   
kâte-ye karini

Fr.: nominatif   

Grammar: In certain inflected languages (as Sanskrit, Avestan, Greek, Latin, German, and Russian), relating to or denoting a case of nouns, pronouns, and adjectives having as its function the indication of the subject of a verb. Same as subjective case.

nominative; → case.

nâ- (#)

Fr.: non-   

A prefix meaning "not."

From O.Fr. non-, from L. non "not," from Old L. noenum "not one;" in some cases perhaps from M.E. non "not" (adj.), from O.E. nan.

Nâ- "no, not," variants na, ni, ma- (prohibitive) "not;" from Mid.Pers. nê, ma "no, not;" O.Pers. naiy, nai "not;" Av. nôit, naē "not;" cf. Skt. "not;" cf. L. ne-, in-, un-; Gk. ni; Lith. ; O.C.S. ne "not;" PIE *ne-.

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.


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-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.

nâyonidé (#)

Fr.: non ionisé   

Not ionized, → neutral.

non-; → ionized.

non-local thermodynamic equilibrium (NLTE)
  ترازمندی ِ گرماتوانیک ِ نامحلی   
tarâzmandi-ye garmâtavânik-e nâmahali

Fr.: hors équilibre thermodynamique local   

A physical condition in which the assumption of the → local thermodynamic equilibrium does not hold.

non-; → local thermodynamic equilibrium.

non-luminous matter
  ماده‌ی ِ ناتابان   
mâdde-ye nâtâbân

Fr.: matière non lumineuse   

Not ordinary matter. Same as → dark matter.

non-; → luminous; → matter.

non-radial pulsation
  تپش ِ ناشعاعی   
tapeš-e nâšo'âyi

Fr.: pulsation non-radiale   

A type of stellar pulsation in which waves run in different directions on and beneath the surface of a star.

non-; → radial; → pulsation.

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.

mekânik-e nâ-bâzânigi-mand
