metastable; metastability
Technical term in physics and chemistry describing a state that is stable under small disturbances but not at the lowest possible energy; can transition to a more stable state with sufficient perturbation.
準安定状態にある原子は、わずかな刺激でより低いエネルギー状態に遷移する。
An atom in a metastable state transitions to a lower energy state with a slight stimulus.
This alloy takes a metastable phase at room temperature.
