interstellar polarization
  قطبش ِ اندر-اختری   
qotbeš-e andaraxtari

Fr.: polarisation interstellaire   

The polarization of starlight caused by aligned → interstellar grains, so that initially → unpolarized light from a star is partially polarized by the time it reaches the Earth.

interstellar; → polarization.

interstellar radiation field
  میدان ِ تابش ِ اندر-اختری   
meydân-e tâbeš andaraxtari

interstellar reddening
  سُرخش ِ اندر-اختری   
sorxeš-e andaraxtari

Fr.: rougissement interstellaire   

The dimming of light during its travel in the → interstellar medium due to absorption by → intervening → dust grains. Since shorter wavelengths are particularly affected, the spectrum of the light is increasingly dominated by the long wavelength end of the spectrum. As a result, the light is "reddened" as it travels through space. Robert J. Trumpler (1886-1956), a Swiss-American astronomer, was the first to produce a definite evidence of the existence of → interstellar extinction and to estimate its magnitude (1930).

interstellar; → reddening.

interstellar reddening curve
  خم ِ سُرخش ِ اندر-اختری   
xam-e sorxeš-e andaraxtari

Fr.: courbe de rougissement interstellaire   

A graph showing the relation between → interstellar absorption (in magnitudes) and wavelength.

interstellar; → reddening; → curve.

interstellar scintillation
  سوسوی ِ اندر-اختری   
susu-ye andaraxtari

Fr.: scintillation interstellaire   

An apparent twinkling of the signals from distant point-like radio sources (pulsars). It is due to turbulence, i.e. fluctuations in the electron density of the interstellar ionized gas, through which the signals have passed on their way to Earth.

interstellar; → scintillation.

interstice
  اندرجا   
andarjâ (#)

Fr.: interstice   

1) A minute gap between the adjacent parts of a body or objects close together.
2) In a crystal lattice, the empty space between adjacent atoms. The interstices are of two types: Tetrahedral-interstices and Octahedral-interstices. Also called → interstitial site.

From L. interstitium "space between; interval," from intersistere, from → inter- "between," + stem of stare "to stand," cognate with Pers. istâdan, → stand

Andarjâ, literally "a place between," from andar "between," → inter-, + , → place.

interstitial
  اندرجایی   
andarjâyi

Fr.: interstitiel   

1) Pertaining to, situated in, or forming → interstices.
2) → interstitial atom.

interstice; → -al.

interstitial atom
  اتم ِ اندرجایی   
atom-e andarjâyi

Fr.: atom interstitiel   

In a → crystal, an imperfection caused by the presence of an extra atom that occupies a place outside the normal → lattice position. It may be the same type of atom as the others (self interstitial) or an → impurity atom.

interstitial; → atom.

interstitium
  اندرجایان   
andarjâyân

Fr.: interstitium   

A network of fluid-filled spaces in the body's connective tissues all over the body. It lies below the skin's surface and surrounds arteries, muscles, and the digestive and urinary tracts in a layer long thought to be dense connective tissue. Interstitium could be the largest organ in the human body

From L. interstitium, → interstice.

Andarjâyân, from andarjâ, → interstice, + euphonic sound -y-, + relation suffix -ân.

intersystem
  اندر-راژمان   
andar-râžmân

Fr.: inter-système   

Describing something that involves mutual relations between systems.

inter-; → system.

intersystem crossing
  گذر ِ اندر-راژمانی   
gozar-e andar-râžmâni

Fr.: conversion intersystème   

A → radiationless relaxation process in which a molecule in some excited → electronic state converts to a state of different spin → multiplicity. Intersystem crossing is analogous to → internal conversion.

intersystem; → crossing.

intersystem line
  خط ِ اندر-راژمانی   
xatt-e andar-râžmâni

Fr.: raie semi-interdite   

In spectroscopy, same as → semi-forbidden line.

inter-; → system.

interval
  اندروار   
andarvâr (#)

Fr.: intervalle   

1) Math.: A portion of a real line (i.e. a line with a fixed scale so that every real number corresponds to a unique point on the line) between two designated endpoints. → span.
2) Music: Difference in pitch between two tones of a scale.

From O.Fr. intervalle, from L.L. intervallum, originally "space between two palisades or ramparts," from → inter- "between" + vallum "rampart."

Andarvâr, literally "between walls," from andar-inter- + vâr "wall," as in divâr "wall" (originally "fortress wall," from *dida-vāra-), variant bâru "wall, rampart, fortification; fort; tower;" Mid.Pers. bâr, var "enclosure, defences, fortress;" Av. var- "castle."

intervene
  اندرگمیدن   
andargamidan

Fr.: intervenir   

1) To occur or be between two things.
2) To occur or happen between other events or periods.

Fr.: intervention   

The act or fact of intervening.

M.E., from M.Fr. intervention, or directly from L.L., from L. intervenire "to come between, interrupt," from → inter-, + venire "to come," as below.

Andargam "coming between," from andar- "between," → inter-, + gam "to come;" cf. Av./O.Pers. gam- "to come; to go," Mod./Mid.Pers. gâm "step, pace," âmadan "to come;" cf. Skt. gamati "goes;" Gk. bainein "to go, walk, step;" L. venire "to come;" O.H.G. queman "to come;" E. come; PIE root *gwem- "to go, come."
