stationary black hole siyah-câl-e istvar Fr.: trou noir stationnaire A → black hole with zero → angular momentum, that does not rotate. → stationary; → black hole. |
stationary limit surface ruye-ye hadd-e istvar Fr.: surface limite stationnaire A property of → space-time outside a → rotating black hole, which consists of a surface which geometrically bounds the → ergosphere outward. At the stationary limit a particle would have to move with the local light velocity in order to appear stationary to a distant observer. This is because the space here is being dragged at exactly the speed of light relative to the rest of space. Outside this limit space is still dragged, but at a rate less than the speed of light. Also known as → static limit. → stationary; → limit; → surface. |
stationary noise nufe-ye istvar Fr.: bruit stationnaire Electronics: A random noise whose intensity remains constant with time. → stationary; → noise. |
stationary orbit madâr-e istvar Fr.: orbite stationnaire An orbit in which the satellite revolves about the primary at the angular rate at which the primary rotates on its axis. From the primary, the satellite thus appears to be stationary over a point on the primary. → stationary; → orbit. |
stationary phase fâz-e istvar Fr.: phase stationnaire Mechanics: The condition of a body or system at rest. → stationary; → phase. |
stationary point noqte-ye istvar Fr.: station Of a planet, the position at which the rate of change of the apparent right ascension of a planet is momentarily zero. → stationary; → point. |
stationary satellite mâhvâre-ye istvar Fr.: satellite stationnaire An artificial satellite in a synchronous orbit. → geostationary orbit → stationary; → satellite. |
stationary wave mowj-e istvar Fr.: onde stationnaire Same as → standing wave. → stationary; → wave. |
statistical âmâri (#) Fr.: statistique Of, pertaining to, consisting of, or based on → statistics. Statistic, from → statistics + → -al. |
statistical equilibrium tarâzmandi-ye âmâri Fr.: équilibre statistique A state in which the average density of atoms per cubic centimeter in any atomic state does not change with time and in which, statistically, energy is equally divided among all degrees of freedom if classical concepts prevail. → statistical; → equilibrium. |
statistical hypothesis engâre-ye âmâri Fr.: hypothèse statistique An assumed statement about the way a → random variable is distributed. A statistical hypothesis generally specifies the form of the → probability distribution or the values of the parameters of the distribution. The statement may be true or false. See also → null hypothesis. → statistical; → hypothesis. |
statistical hypothesis testing âzmun-e engâre-ye âmâri Fr.: test d'hypothèse statistique A method of making decision between rejecting or not rejecting a → null hypothesis on the basis of a set of observations. → statistical; → hypothesis; → test. |
statistical inference darbord-e âmâri Fr.: inférence statistique The process of inferring certain facts about a → statistical population from results found in a → sample. → statistical; → inference. |
statistical law qânun-e âmâri (#) Fr.: loi statistique A law that governs the behavior of a system consisting of a large number of particles and which differs from the laws obeyed by each of the particles making up the macroscopic system. See also → dynamical law. → statistical; → law. |
statistical mechanics mekânik-e âmâri (#) Fr.: mécanique statistique → statistical; → mechanics. |
statistical parallax didgašt-e âmâri Fr.: parallaxe statistique The mean parallax of a group of stars that are all at approximately the same distance, as determined from their radial velocities and proper motions. → statistical; → parallax. |
statistical physics fizik-e âmâri (#) Fr.: physique statistique The branch of physics that applies methods of → probability theory and → statistics to the behavior of large numbers of microscopic particles (such as molecules, atoms, or subatomic particles) in order to explain and predict the overall properties of the system composed of such particles. → statistical; → physics. |
statistical population porineš-e âmâri Fr.: population statistique Any collection of individuals or items from which → samples are drawn. See also → finite population, → infinite population. → statistical; → population. |
statistical thermodynamics garmâtavânik-e âmâri Fr.: thermodynamique statistique Same as → statistical mechanics. → statistical; → thermodynamics. |
statistical weight vazn-e âmâri Fr.: poids statistique 1) Statistics: A number assigned to each value or range of values of a
given quantity, giving the number of times this value or range of
values is found to be observed. → statistical; → weight. |
