Steady state (disambiguation)

Steady state may refer to:

• Steady state (systems) an operating condition in thermodynamic and other systems or processes when variables stay constant as time passes.
  • Steady-state economy, an economy made up of a constant population size and a constant stock of physical wealth (capital).
  • Steady-state equilibrium (monetary theory), an economic situation where neutrality of money coincides with zero population growth.
  • Steady-state rate of growth (neoclassical growth theory), an economy featuring an equi-proportionate increase in capital and labour
  • Steady state (electronics), a state existing in a circuit or network when all transients have died away.
  • Steady state (chemistry), a term in chemical kinetics meaning the situation in which all state variables of an open system are constant in time.
  • Steady state (biochemistry), a situation in which certain parameters of cells or organs, usually concentrations of molecules, are constant in time
  • Steady state (physiology), also known as homeostasis, a system in which a particular variable is not changing but energy must be continuously added to maintain this variable constant.
• Dynamic equilibrium commonly observed in dynamical systems.

It may also refer to:

• Steady-state model, a non-standard cosmological view developed in 1949 by Fred Hoyle and others as an alternative to the Big Bang theory.
