A time which represents the speed with which a particular system can respond to change, typically equal to the time taken for a specified parameter to vary by a factor of 1−1/e (approximately 0.6321).
〔物理〕时间常数
Example sentencesExamples
The hyperinflation may be explained completely by the time constant of the respiratory system exceeding the time available for tidal exhalation.
One way is to vary the time constant of the slow negative-feedback variable.
The time constant of the signal-recovery process yields information on potential heart damage.
This time constant, like that for the half-life of a radionuclide, doesn't tell you an age necessarily - assumptions must be applied first.
This time constant reflects, rather, the lifetime of the first excited singlet state of the complex, which decays rapidly owing to intersystem crossing.

A time that represents the speed with which a particular system can respond to change, typically equal to the time taken for a specified parameter to vary by a factor of 11/e (approximately 0.6321).
