altazimuth instrument
  سازال ِ فرازا-سوگان   
sâzâl-e farâzâ-sugâni

Fr.: instrument altazimutal

astronomical; → instrument.

instrument
  ۱) ساز؛ ۲) سازال   
1) sâz; 2) sâzâl

Fr.: instrument   

1) An object used for producing music.
2) A measuring device designed to record the present value of a quantity under observation.

From O.Fr. instrument, from L. instrumentem "a tool, apparatus, furniture," from instruere "to arrange, furnish," from → in- + struc- (var. s. of struere "to put together") + -tus p.p. suffix.

1) Sâz "(musical) instrument; apparatus; harness; furniture," from sâzidan, sâxtan "to build, make, fashion; to adapt, adjust, be fit" (from Mid.Pers. sâxtan, sâz-, Manichean Parthian s'c'dn "to prepare, to form;" Av. sak- "to understand, to mark," sâcaya- (causative) "to teach").
2) Sâzâl, from sâz + -âl, → -al.

instrument error
  ایرنگ ِ سازال، خطای ِ ~   
irang-e sâzâl, xatâ-ye ~

Fr.: erreur instrumentale   

The correctable part of the inaccuracy of a measuring instrument.

instrument; → error.

instrumental
  سازالی   
sâzâli

Fr.: instrumentale   

Of, relating to, or performed by or with one or more instruments.
See also:
instrumental broadening, → instrumental flexure, → instrumental magnitude, → instrumental profile, → instrumental response function, → instrumentalism, → instrumentalist.

Adj. of → instrument.

instrumental broadening
  پهنش ِ سازالی   
pahneš-e sâzâli

Fr.: élargissement instrumental   

The broadening of a point source caused by the response functions of the telescope and the instrument used.

instrumental; → broadening.

instrumental flexure
  چفتگی ِ سازال   
caftegi-ye sâzâl

Fr.: flexion d'instrument   

An image defect caused by the mechanical flexure of materials; for example the curved-shape image of a long slit in a spectrograph.

instrumental; flexure, from L. flexura "a bending, turning, winding," from flectere "to bend, turn."

Caftegi, from caftidan "to bend, incline," cafté "curved, bent;" sâzâli, → instrumental.

instrumental magnitude
  برز ِ سازالی   
borz-e sâzâli

Fr.: magnitude instrumentale

instrumental; → magnitude.

instrumental profile
  فراپال ِ سازالی   
farâpâl-e sâzâli

Fr.: profil instrumental

instrumental; → profile.

instrumental response function
  کریای ِ پاسخ ِ سازال

Fr.: fonction de la réponse instrumentale   

The mathematical form of the way an instrument affects the input signal.

instrumental; → response; → function.

instrumentalism

sâzâlbâvari

Fr.: instrumentalisme   

In the philosophy of science, the pragmatic view that a scientific theory is no more than a useful instrument or tool for getting our experiences in some order.

instrumental; → -ism.

Fr.: instrumentation   

1) The design and use of scientific instruments for detection, measurement, control, computation, and so on.
2) The ensemble of instruments contained in a given machine or system.

From → instrument + -ation a combination of -ate and -ion, used to form verbal nouns.

Sâzâlgari, noun from sâzâlgar, → instrumentalist. Sâzâlgân, with plurality suffix -gân.
