The act or process of converting; state of being converted. → convert.
Verbal noun of → convert.
Hâgard, from hâ- prefix denoting "reversal; to," sometimes creating nuance [Dehxodâ], + gard present stem of gardidan, gaštan "to change; to turn;" Mid.Pers. vartitan; Av. varət- "to turn, revolve;" cf. Skt. vrt- "to turn, roll," vartate "it turns round, rolls;" L. vertere "to turn;" O.H.G. werden "to become;" PIE base *wer- "to turn, bend."
Fr.: facteur de conversion
1) A numerical factor that, by multiplication or division, translates one
unit or value into another.
→ conversion; → factor.
frequency to wavelength conversion
hâgard-e basâmad bé mowj-tul
Fr.: conversion fréquence / longueur d'onde
Deriving the → wavelength of an undulatory phenomenon from
its → frequency, and vice versa.
→ frequency; → wavelength; → conversion.
hertz to meter conversion
hâgard-e hertz bé metr
Fr.: conversion hertz / mètre
→ frequency to wavelength conversion.
→ hertz; → meter; → conversion.
Fr.: conversion interne
A → radiationless relaxation process in which a molecule in some excited → electronic state converts to a state of the same → multiplicity but of lower electronic energy and in which the lost electronic energy is converted initially into vibrational energy.
→ internal; → conversion.
Meteo.: A departure from the usual decrease or increase with altitude of the value of an atmospheric property. It almost always refers to a temperature inversion, i.e., an increase in temperature with altitude. Chemistry: To subject to → inversion.
Verbal noun of → invert.
Fr.: couche d'inversion
Meteo.: The atmospheric layer in which the temperature gradient is
inverted, that is increases; → inversion. The inversion layer
tends to prevent the air below it from rising, thus trapping any pollutants that are present.
number system conversion
hâgard-e râžmân-e adadi
Fr.: conversion de système de numération
The conversion of a → number system
with a given → base to another system with a
different base; such as the conversion of a → decimal number
(base 10) to a → binary number system
In order to convert a number into its representation in a different
number base, we have to express the number in terms of powers of the other base.
For example, to convert the decimal number 100 to base 3, we must figure out how to
express 100 as the sum of powers of 3. We proceed as follows:
→ number; → system; → conversion.
vâgardâni-ye porineš, vâruneš-e ~
Fr.: inversion des populations
In physics, specifically statistical mechanics, the state of an atomic or molecular system in which the number of members in an excited state is larger than those in lower energy states. → optical pumping; → inverted population.
→ population; → inversion.
Fr.: inversion de température
Meteo.: A reversal in the normal temperature decrease, the temperature rising with increased elevation in the atmosphere instead of falling. A layer in which temperature increases with altitude.
→ temperature; → inversion.
Fr.: convesrion de l'uranium
A chemical process converting the → yellowcake to → uranium hexafluoride. The uranium hexafluoride is heated to become a gas and loaded into cylinders. When it cools, it condenses into a solid.
→ uranium; → conversion.
A particular form or variant of something.
M.E., from M.Fr. version, from M.L. versionem (nominative versio) "a turning," from p.p. stem of L. vertere "to turn;" cognate with Pers. gardidan "to change," as below.
Gardâk, present stem of gardidan "to change, to turn" (Mid.Pers. vartitan "to change, to turn;" Av. varət- "to turn, revolve;" cf. Skt. vrt- "to turn, roll," vartate "it turns round, rolls;" L. vertere "to turn;" O.H.G. werden "to become;" PIE base *wer- "to turn, bend") + -âk noun suffix.
