Fr.: perte par hystérésis
Dissipation of energy which occurs, due to magnetic hysteresis, when the magnetic material is subject to changes of magnetization.
In physics, a measure of the energy, mass, or other physical quantities lost in a system, by conversion or external effects.
From O.E. los "loss, destruction," from P.Gmc. *lausa, from PIE base *leu- "to loosen, divide, cut apart, untie, separate" (cf. Gk. lyein "to loosen, untie, slacken," lysus "a loosening;" L. luere "to loose, release, atone for;" Skt. lunati "cuts, cuts off," lavitram "sickle;" Pers. las "loose," lâ "slit, cut;" → analysis).
Dastraft, literally "gone from hand," from dast "hand" (Mid.Pers. dast; O.Pers. dasta-; Av. zasta-; cf. Skt. hásta-; Gk. kheir; L. praesto "at hand;" Arm. jern "hand;" Lith. pa-žastis "arm-pit;" PIE *ghes-to-) + raft p.p. of raftan "to go, elapse, glide by, depart" (Mid.Pers. raftan, raw-, Proto-Iranian *rab/f- "to go; to attack").
Fr.: fibre à faible perte
Optical fiber that transmits a greater percentage of input light than does high-loss step-index fiber.
Fr.: perte de masse
The outpouring of particles and gas from a star, occurring at varying rates and by a variety of processes throughout a star's lifetime. → Bipolar flows are believed to be due to mass loss by forming → protostars, while → massive stars lose their mass through powerful → stellar winds.
mass loss rate
nerx-e dastraft-e jerm
Fr.: taux de perte de masse
The rate with which the → mass loss process takes place, usually expressed in → solar mass per year. → radiation-driven mass loss. The mass loss rate and the → terminal velocity are anti-correlated, since the → wind momentum is constant, → bi-stability jump.
Fr.: perte ohmique
Same as → Ohmic dissipation.
radiation-driven mass loss
dastraft-e jerm az râh-e bâd-e tâbeši
Fr.: perte de masse par vent radiatif
Fr.: perte de transmission
A decrease in power in transmission from one point to another.
