ground state
(redirected from Stationary state)

   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.01 sec.
ground state
n.
The state of least possible energy in a physical system, as of atoms or molecules.

ground state,
1 the lowest energy level of a physical system. See also fatigue state.
2 the stable form of an atom or molecule.

state [stāt]
condition or situation.
alpha state the state of relaxation and peaceful awakefulness associated with prominent alpha brain wave activity.
anxiety state the condition of experiencing undue anxiety, as in anxiety disorders.
excited state the condition of a nucleus, atom, or molecule produced by the addition of energy to the system as the result of absorption of photons or of inelastic collisions with other particles or systems.
ground state the condition of lowest energy of a nucleus, atom, or molecule.
persistent vegetative state a condition of profound nonresponsiveness in the wakeful state caused by brain damage at whatever level and characterized by a nonfunctioning cerebral cortex, the absence of any discernible adaptive response to the external environment, akinesia, mutism, and inability to signal; the electroencephalogram may be isoelectric or show abnormal activity. Vegetative states raise ethical questions regarding appropriate care, use of resources, and allowing a patient to die.
refractory state a condition of subnormal excitability of muscle and nerve following excitation.
resting state the physiologic condition achieved by complete bed rest for at least 1 hour.
steady state dynamic equilibrium.

ground state,
n the state of a nucleus, an atom, or a molecule when it has its lowest energy. All other states are termed
excited.

state
condition or situation.

excited state
the condition of a nucleus, atom or molecule produced by the addition of energy to the system as the result of absorption of photons or of inelastic collisions with other particles or systems.
ground state
the condition of lowest energy of a nucleus, atom or molecule.
refractory state
a condition of subnormal excitability of muscle and nerve following excitation.
resting state
the physiological condition achieved by complete rest for at least 1 hour.
steady state
dynamic equilibrium.

The author describes the origins of quantum mechanics, its mathematical tools and postulates, one- and three-dimensional problems, angular momentum, identical particles, approximation methods for stationary states, scattering theory, time-dependent perturbation theory, and other related topics.
Second, it indicates the concomitant rise in the profit rate that is ignored by present-day trade textbooks, but that Ricardo regarded as an equally important gain from trade for a country such as England that was in the throes of the industrial revolution, aimed to become the "workshop of the world," and wished to ward off the approach toward a stationary state that was otherwise foreshadowed by the classical school of thought.
It was observed here that a stationary state corresponding to a "dry" paint state was reached in approximately 30 min.
