Steady state may refer to:
It may also refer to:
- Steady stateSteady stateA system in a steady state has numerous properties that are unchanging in time. This implies that for any property p of the system, the partial derivative with respect to time is zero:...
(systems) an operating condition in thermodynamicThermodynamicsThermodynamics is a physical science that studies the effects on material bodies, and on radiation in regions of space, of transfer of heat and of work done on or by the bodies or radiation...
and other systems or processes when variables stay constant as time passes.- Steady state economy, a stable economy maintained at a sustainable equilibrium.
- Steady state (electronics)Steady state (electronics)In electronics, steady state is an equilibrium condition of a circuit or network that occurs as the effects of transients are no longer important....
, a state existing in a circuit or network when all transients have died away. - Steady state (chemistry)Steady state (chemistry)In chemistry, a steady state is a situation in which all state variables are constant in spite of ongoing processes that strive to change them. For an entire system to be at steady state, i.e. for all state variables of a system to be constant, there must be a flow through the system...
, a central term in chemical kinetics. - Steady state (biochemistry)Steady state (biochemistry)In ionic steady state, cells maintain different internal and external concentrations of various ionic species. Cell membranes are permeable to sodium and various other ions, so in order to maintain a constant ionic concentration the cell must expend energy to actively transport these ions against...
, regarding ions across cell membranes - Steady state (physiology), also known as homeostasisHomeostasisHomeostasis is the property of a system that regulates its internal environment and tends to maintain a stable, constant condition of properties like temperature or pH...
, a system in which a particular variable is not changing but energy must be continuously added to maintain this variable constant. - Steady state (pharmacokinetics)
- Dynamic equilibriumDynamic equilibriumA dynamic equilibrium exists once a reversible reaction ceases to change its ratio of reactants/products, but substances move between the chemicals at an equal rate, meaning there is no net change. It is a particular example of a system in a steady state...
commonly observed in dynamical systemDynamical systemA dynamical system is a concept in mathematics where a fixed rule describes the time dependence of a point in a geometrical space. Examples include the mathematical models that describe the swinging of a clock pendulum, the flow of water in a pipe, and the number of fish each springtime in a...
