However, some special states may live much longer, up to several seconds or more before they decay, and are therefore called metastable states.
However, upon termination of the light, the drain current decayed and settled to a metastable state, which was the store/read state as a function of time.
The relaxed state is a thermodynamic state that is experimentally accessible via relaxation tests since, according to De Donder [17], such a state generalizes Duhem's metastable state.
The result is a complex multiphase system, the structure of which is often in a metastable state that tends to separate into a polymer-rich phase and an asphalt-rich phase.
In this metastable state, aggregation of the dissolved gas molecules into clusters may be imagined.
However, in some cases, such a metastable state does not exist; that is, no receding contact angle will be observed, or the receding contact angle is equal to zero.
This broad exotherm is due to relaxation from a metastable state.
Because of the crystalline content, the radiation-crosslinked PE is in a stressed metastable state with the memory of its initial dimensions.
The melting process of the crystals formed from flexible linear macromolecules below the equilibrium melting temperature is usually an irreversible phenomenon since the crystalline state is far from an equilibrium state due to a quench effect to develop a metastable state.
That is, the blends, even at long mixing times, may be stuck in a metastable state due to the melting order of the blend components.
This project will a) investigate the formation of high temperature processing in a radio frequency inductively coupled plasma, and b) process calcium phosphates through metastable states to capture structural modifications for enhancing properties.
The core of the technique is the analysis of metastable states and using them to simplify the computational problem.
