steady state

listen to the pronunciation of steady state
İngilizce - İngilizce
Any state that does not change over time, or is in a dynamic equilibrium
system has properties which do not change with time
A long-run equilibrium with constant capital per person (p 633)
The level of drug accumulation in the blood when input and output are equal
Strain invariance of the microfabric on the sample scale
A situation in which the relevant variables are constant over time
Condition of a body or system in which the conditions at each point do not change with time, after initial fluctuations have disappeared
Input/Output are Balanced at a Point Below Max Limits of System
A process in biochemistry that refers to situations of high activity even though the overall structure and composition of cells seems not to change Steady state processes are used to explain metabolic homeostasis The flow of water molecules in a river or free flowing traffic are examples of steady state processes where the overall movement of water molecules (cars) does not appear to change, although the composition of particular molecules (cars) is constantly changing
A situation in which a model, process, or device exhibits stable behavior independent of time Also called equilibrium
A system is in a steady state when the state of the system is independent of the time of the observation of this state For example, a waiting line system is in a steady state if its arrival and service rates dop not change with time Conversely, this system is not in a steady state if its arrival rate increases from 11: 00AM to noon
A situation in which the variables in an economic model (e g , population, the labor force, output, per capita income, the capital stock, etc ) change at constant percentage rates over time The rates of change may differ from one variable to another, but they must be consistent with each other within the confines of the model These rates of change may be positive, zero or negative
an open system that has no macroscopic changes; however, this is because any materials that leave the system are immediately replaced
A stable condition that does not change over time or in which change in one direction is continually balanced by change in another
The behavior of a vibrating system after it has had plenty of time to settle into a steady response to a driving force In the steady state, the same amount of energy is pumped into the system during each cycle as is lost to damping during the same period
A condition where the AED has reached a stable blood level so that if the person continues to take the same dose each day the level will stay the same With most AEDs steady state blood levels occur after five half lives
A condition in which circuit s values remain essentially constant, occurring after all initial transients or fluctuating conditions have settled down
steady state theory
A cosmological model of the universe in which matter is continuously created as the universe expands
steady state theory
The theory describing a steady state universe. Also called continuous creation theory. the idea that things in space have always existed and have always been moving away from each other as new atoms begin to exist big bang theory
steady state universe
A model universe in which the density of matter is constant over space and time, and the expansion of the universe, required on other grounds, is compensated for by the continuous creation of matter. The model is generally believed to be discredited by the discovery of the background radiation of the big bang
Characteristic of a steady state
steady-state theory
Concept of an expanding universe whose average density remains constant, matter being continuously created throughout it to form new stars and galaxies at the same rate that old ones recede from sight. A steady-state universe has no beginning or end, and its average density and arrangement of galaxies are the same as seen from every point. Galaxies of all ages are intermingled. The theory was first put forward by William Macmillan (1861-1948) in the 1920s and modified by Fred Hoyle to deal with problems that had arisen in connection with the big-bang model. Much evidence obtained since the 1950s contradicts the steady-state theory and supports the big-bang model
