Capable of or inclined to resistance; resisting.
A property of a → conductor which is defined as the ratio of the → electric intensity (E) to the → current density (J): ρ = E/J. The greater the resistivity, the greater the intensity needed to establish a given current density, or the smaller the current density for a given intensity. A "perfect" conductor would have zero resistivity, and a "perfect" → insulator an infinite resistivity.
An electrical component used to introduce a known value of resistance into a circuit.
1) The degree to which an → optical system renders visible
separate parts of an object. Also known as → angular resolution and
→ spatial resolution. See also
→ spectral resolution.
Verbal noun of → resolve.

Skt. sā- "to bind, fasten, fetter," sitá- "bound," ví-sita- "untied."
Past participle of → resolve.
Fr.: raie résolue
A → spectral line that is not contaminated by other nearby lines.
Fr.: pouvoir de résolution, pouvoir séparateur
A measure of an optical system's ability to produce an image which separates two points or parallel lines on the object.
1) The state of a → mechanical system
in which the → amplitude of → oscillation
is increased when it is subjected to stimulus from another source at or near its
own natural → frequency.
Resonance, from M.Fr. resonance, from L. resonantia "echo," from resonare "to resound," from re- "again, back" + sonare "to sound."
Bâzâvâyi, from bâz- "again, back," → re-, + âvâ "voice, sound" (related to âvâz "voice, sound, song," bâng "voice, sound, clamour" (Mid.Pers. vâng), vâžé "word;" Av. vacah- "word," vaocanghê "to decalre" (by means of speech), from vac- "to speak, say;" cf. Skt. vakti "speaks, says," vacas- "word;" Gk. epos "word;" L. vox "voice;" PIE base *wek- "to speak") + -yi noun suffix.
Fr.: capture résonante
Capture by an atomic nucleus of a particle whose energy is equal to one of the energy levels of the nucleus.
Fr.: fréquence de résonance
The frequency at which a system is in → resonance.
Fr.: raie de résonance
For a particular atom, the spectral line corresponding to the longest wavelength arising from a transition between the ground state and an excited state.
Fr.: orbite de résonance
An orbit which is in → orbital resonance with another orbit.
Fr.: particule de résonance
A hadronic particle which exists for only a very brief time (10-23 seconds) before decaying into hadrons; also called resonance. The existence of a resonance cannot be observed directly; it can only be inferred from studying the longer-lived products of its decay.
resonance region neutron
notron-e nâhiye-ye bâzâvâyi
Fr.: neutron dans la région de résonance
A neutron with an energy between 1 eV and 0.01 MeV.
Pertaining to a system in a state of → resonance; producing resonance; resounding.
Verbal adj. from → resonate.
Fr.: circuit résonnant
An electrical circuit containing both capacitance and inductance in such a way that a certain periodic electric oscillation will reach maximum amplitude.
Fr.: réaction résonnante
A nuclear reaction whose probability is enhanced at an energy corresponding to an energy level of one of the nuclei. → resonance capture.
Fr.: relaxation résonnante
A process whereby stellar orbit relaxation can be dramatically enhanced in orbits in a nearly Keplerian star cluster close to a → massive black hole (MBH). This process can modify the angular momentum distribution and affect the interaction rates of the stars with the MBH more efficiently than non-resonant relaxation. In the standard relaxation picture, each encounter is random and uncorrelated, so stars undergo a random walk. Relaxation is driven by the diffusion of energy which then leads to angular momentum transfer. However, in a stellar cluster around a MBH, each star will be on a Keplerian orbit, which is a fixed ellipse in space. The orbits of two nearby stars will thus exert correlated torques on one another, which can lead to a direct resonant evolution of the angular momentum. Since resonant relaxation increases the rate of angular momentum scattering, stars reach highly eccentric orbits more rapidly where they can become → extreme mass ratio inspiral (EMRI)s (Rauch, K.P., Tremaine, S., 1996, arXiv:astro-ph/9603018; Gair J.R. et al. 2013, Living Rev.
