Fr.: système dissipatif
General: To separate from association of any kind.
Verbal form of → dissociation.
General: An act or instance of dissociating; the state of being dissociated.
Fr.: énergie de dissociation
Energy required to dissociate a molecule. → dissociate.
Of, relating to, or tending to produce → dissociation.
Adj. of → dissociate.
Fr.: recombinaison dissociative
A process where a positive molecular ion recombines with an electron, and as a result it dissociates into two neutral products. For example, AB+ + e-→ A + B, where e- is an electron, AB+ is a diatomic or polyatomic molecular ion, and A and B are the neutral fragmentation products. Dissociative recombination is the dominant recombination process in planetary ionospheres and interstellar clouds.
Chemistry: The process by which a solid, gas, or liquid is dispersed homogeneously in a gas, solid, or a liquid.
Verbal noun of → dissolve.
To make a solution of, as by mixing with a liquid; pass into solution.
From L. dissolvere "to loosen up, break apart," from → dis- "apart" + solvere "to loose, loosen, untie," from PIE *se-lu-, from reflexive pronoun *swe- + base *leu- "to loosen, divide, cut apart" (cf. Gk. lyein "to loosen, release, untie," Skt. lunati "cuts, cuts off," lavitram "sickle," O.E. leosan "to lose," leas "loose."
Vâluyidan, infinitive from stem vâlu(y)-, from vâ-→ de- + lu, variant of Mod.Pers. las "loose," lâ "slit, cut," luš "torn," lok "torn, piece," lâc "open, wide open" (→ analysis), from PIE *leu- "to loosen, divide, cut apart."
Absence or lack of symmetry
Fr.: éjecta distaux
Geology: Impact ejecta found at distances more than 5 crater radii from the rim of the source crater.
apest, durâ (#), duri (#)
1) The separation/length in space/time between two things/events.
M.E., from O.Fr., from L. distantia "a standing apart," from distantem (nominative distans) "standing apart, separate, distant," pr.p. of distare "to stand apart," from → dis- "apart, off" + stare "to stand," (cf. Mod.Pers. istâdan "to stand," O.Pers./Av. sta- "to stand, stand still; set," Skt. sthâ- "to stand," Gk. histemi "put, place, weigh," stasis "a standing still").
Apest, literally "standing apart," from apa- prefix denoting
"separation, away, off," → dis-, + est variant of
ist, present stem of istâdan, to stand," as above;" cf.
Choresmian bst "to stand apart," from *apa- + st-
"to stand," → stand.
Fr.: fonction de distance
Same as → metric.
Fr.: module de distance
The difference between the → apparent magnitude (m) of a star or galaxy and its → absolute magnitude (M). It is given by m - M = 5 log d - 5, where d is the distance in → parsecs. For an object that is 10 pc away, the distance modulus is zero.
distance to the horizon
Fr.: distance à l'horizon
The distance separating an observer and the → apparent horizon of the place. Neglecting the → atmospheric refraction, it is given by: d = (2Rh)1/2, where R is the radius of the Earth and h is the observer's height. This can be approximated to: d (km) = 3.57(h)1/2 for a typical value of R = 6378 km. The atmospheric refraction, however, makes the thing more complex, depending on the temperature and density variations along the line of sight. Generally, refraction pushes the apparent horizon about 10% farther.
Fr.: distinct, différent
1) Readily distinguishable from all others.
Past-participle adjective from obsolete distincten "to distinguish one thing from another; make distinct," from O.Fr. distincter, from L. distinctus, p.p. of distinguere "to separate between, mark off."
Bažnâ, literally "high," from Kurd. bažn "height, stature," variants baž, baš "height," bašn, → stature, faš, baš "a horse's mane."
1) The act or an instance of distinguishing or differentiating.
Serving to identify; distinguishing or characteristic.
Fr.: distinctement, clairement
In a clear and noticeable way; clearly.
Fr.: distinction, différence
The state or quality of being distinct.
1) To perceive as being different or distinct.
ME. distingwen, from O.Fr. distinguer, from L. distinguere "to separate between, divide, mark off," perhaps literally "separate by pricking," from assimilated form of → dis- "apart" + -stinguere "to prick."
Bažnâyidan, verb from bažnâ, → distinct.
