characteristic time; typical reaction time
Rare technical term used in physics, chemistry, or engineering to describe a representative time scale for a process, such as a reaction or relaxation time.
The characteristic time of this reaction is estimated to be about 2 milliseconds.
Compound of 特性 (characteristic, property) and 時間 (time). The exact origin is uncertain; it appears to be a calque or direct translation of the English term 'characteristic time' used in scientific contexts.
