transient phenomenon
Technical term in physics and engineering for a temporary state that occurs when a system changes from one steady state to another, such as electrical transients or thermal transients.
A transient phenomenon was observed right after the circuit was switched on.
To analyze transient phenomena, it is necessary to solve differential equations.
Refers to a steady state, the opposite of a transient state. 過渡現象 describes the behavior before reaching 定常状態.
Compound of 過渡 (kato, 'transition') and 現象 (genshō, 'phenomenon'). The term is a direct translation of the English 'transient phenomenon' and is used primarily in technical contexts.
