Fr.: résolution angulaire
Of a telescope, the smallest angle betwwen two → point sources that produces distinct images. It depends on both the wavelength at which observations are made and on the diameter of the telescope. Same as → spatial resolution.
Chemistry: The process by which a solid, gas, or liquid is dispersed homogeneously in a gas, solid, or a liquid.
Verbal noun of → dissolve.
Fr.: observation à haute résolution
An observation that provides a particularly narrow, peaked image of a point source. → point spread function.
Fr.: résolution d'image
The separation between two detached but adjacent points in an image.
Fr.: solution de Larson-Penston
The analytical solution to the → hydrodynamic equations describing the → collapse of an → isothermal sphere. The Larson-Penston solution is → self-similar for a purely dynamical isothermal collapse with spherical symmetry. It corresponds to the collapse prior to the formation of a → protostar, and thus is suitable for the study of → pre-stellar cores. The Larson-Penston solution was extended by Shu (1977) to obtain a whole family of solutions for this problem.
Named after R. B. Larson (1969, MNRAS 145, 271) and M. V. Penston (1969, MNRAS 144, 425), who simultaneously, but independently, did this study.
Fr.: faible résolution
The quality of an instrument that lacks sufficient resolution for a specific observation. This is a relative quality, but presently a resolution below about 1 arcsecond.
Fr.: solution particulière
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.
resolution of a force
Fr.: résolution de force
Fr.: solution saturée
A solution which can exist in equilibrium with excess of solute. The saturation concentration is a function of the temperature.
Fr.: solution de Schwarzschild
Briefly following Einstein's publication of → General Relativity, Karl Schwarzschild discovered this solution in 1916 (Sitzungsberichte der Königlich Preussischen Akademie der Wissenschaften zu Berlin, Phys.-Math. Klasse, 189); → Schwarzschild black hole.
Fr.: solution singulière, ~ particulière
1) The act of solving a problem, question. The state of being solved.
Verbal noun of → solve.
Fr.: résolution spatiale
The smallest detail that can be seen in an image. Same as → angular resolution.
vâgošud-e binâb, ~ binâbi
Fr.: résolution spectrale
The capacity of a spectrograph to separate two adjacent spectral lines. The theoretical spectral resolution depends on the grating dispersion, grating position, pixel size, collimator and camera focal length, and the entrance slit-width.
Fr.: résolution temporelle
The measure of the ability of an observing system to clearly separate events in time. In other words, the shortest time interval that can be determined between two different events.
Fr.: résolution temporelle
Same → temporal resolution.
