time con·stant

that part of a circuit that determines the time interval over which the rate of electrical events will be averaged; in pulmonary physiology, the factors determining rate of flow in the airways.

time constant

a mathematic term of fixed value used in expressing the rate of change of some variable, such as airflow in the airways, as a function of time.
