noun
steady state
Technical term used in physics, engineering, and systems theory to describe a condition where properties remain constant over time.
このシステムは定常状態に達するまでに時間がかかる。
This system takes time to reach a steady state.
平衡状態 (equilibrium state) emphasizes a balance of opposing forces, while 定常状態 focuses on unchanging properties over time, often in flow systems.
Compound of 定常 (constant, steady) and 状態 (state, condition). The exact historical derivation is uncertain; the term is a modern technical coinage.
