1) diryâz; 2) a), b) giyâné, giyâni; c) giyânbâvar
Fr.: 1) séculaire; 2) laïc
1a) General: Going on from age to age; continuing through long ages.
Secular from O.Fr. seculer, from L.L. sæcularis "of an age, occurring once in an age," from sæculum "age, span of time, generation, the spirit of the age."
1) Diryâz "long lasting, from dir "slowly, tardily;
late" (Mid.Pers. dêr, variants dagr, drâz "long;"
(Mod.Pers. derâz "long," variant Laki, Kurdi
derež); O.Pers. darga- "long;" Av. darəga-,
darəγa- "long," drājištəm
"longest;" cf. Skt. dirghá- "long (in space and time);"
L. longus "long;" Gk. dolikhos "elongated;" O.H.G.,
Ger. lang; Goth. laggs "long;" PIE base
+ yâz present stem of yâzidan "to stretch out the arms; grow up"
(Parthian Mid.Pers. y'd "to reach a goal, come to, stretch out;"
Av. yat- to reach, take one's place," yaiiata "places,"
frā-iiatāt "has reached;" cf. Skt. yat- "to be in place, put in place,
line up;" PIE base *iet- "to be in place").
Fr.: aberration séculaire
The smallest component of the aberration of starlight which is caused by the motion of the solar system through space. → annual aberration; → diurnal aberration.
→ secular; → aberration.
Fr.: accélération séculaire
The apparent gradual increase in the → Moon's motion in its orbit, as measured relative to → mean solar time. Secular acceleration corresponds to an extremely gradual reduction in the speed of the → Earth's rotation. The slow-down of the Earth's spin comes mainly from → tidal frictions from the Moon. Historically, Edmond Halley (1656-1742) was the first to suggest that the Moon's mean rate of motion relative to the stars was gradually increasing. In 1693, Halley compared eclipses of recent, medieval, and classical Babylonian time, and discovered that the Moon's mean motion had been gradually increasing. Using Lunar Laser Ranging measurement, based on laser reflectors left by the Apollo astronauts on the Moon's surface (1969 to 1972), the secular acceleration is derived to be -25".4 ± 0".1 century 2 (Xu Huaguan et al., 1996, in Earth, Moon and Planets 73, 101). This corresponds to a linear increase of about 3.5 cm yr-1 in the mean Earth-Moon distance.
→ secular; → acceleration.

Fr.: changement séculaire
A continuous, non-periodic change in one of the attributes of the states of a system. Often, a change in an orbit due to dissipation of energy. See also → canonical change.
Fr.: instabilité séculaire
Instability caused by a slow dissipation of energy.
→ secular; → instability.
Fr.: parallaxe séculaire
The angle subtended at a star by a baseline that is the distance the Sun moves in a given interval of time with respect to the local standard of rest (4.09 AU per year).
Fr.: perturbation séculaire
A variation of planetary orbital elements which is always in the same direction as time increases.
→ secular; → perturbation.
Fr.: stabilité séculaire
1) The condition in which the equilibrium configuration of a system is
stable over long periods of time.
Fr.: terme séculaire
In perturbation theory used in celestial mechanics, a steadily increasing disturbance. → periodic term.
Fr.: variation séculaire
Same as → secular perturbation.
The view that religious considerations should be excluded from civil affairs or public education.
The process of organizing society or aspects of social life around non-religious values or principles.
