thermal equilibrium

n.
The condition under which two substances in physical contact with each other exchange no heat energy. Two substances in thermal equilibrium are said to be at the same temperature.

As previously described, at t = 0 s the module is in thermal equilibrium with the surroundings.
In case of thermal equilibrium, the side wall temperature corresponds to [T.sub.eq].
Kirchhoff's law extended much beyond Stewart's [3] and stated that, given thermal equilibrium, the radiation contained within an arbitrary cavity was depended only on the temperature of the enclosure and on the frequency of observation [1,2].
It should be noted that, according to Kirchhoff's law, an object emits as much radiation as it absorbs in thermal equilibrium, therefore it is reasonable we study the emitter's radiation spectrum from calculating its optical absorption.
Logarithmic corrections arises from loop quantum gravity due to thermal equilibrium and quantum fluctuations [68-74].
While Calcote and King did conclude that thermal equilibrium does not exist between the ions and their parent species, and that chemi-ions could be responsible for the higher ion concentrations deduced from experiments, they did not extend their computations to include these effects.
According to the above it is clear that the nature of this maximum is associated with the process of slowing down of neutrons in a non-equilibrium neutron system, which is generated by an isotropic source of neutrons in thermalized system of nuclei of moderation medium, and cannot be explained only by thermalized part of neutron system, i.e., thermal equilibrium part of the neutron system, and cannot be described by Maxwell distribution.
This photographically fast Newtonian reflector is built around a 150-mm parabolic primary mirror manufactured from B270 glass that reaches thermal equilibrium quickly.
The porous media model energy equation can use the thermal equilibrium model or the thermal nonequilibrium model.
[T.sub.m] is similar to the contents temperature at thermal equilibrium when the calorimeter is perfectly adiabatic.
Because of the difference in thermal diffusivity between the metal foam and the PCM, thermal equilibrium is not assured.
