Meanings of current deactivation in English

Tail current deactivation kinetics was biexponential with time constants of 0.12 and 1.5s.

This, and the evidence in the preceding paragraph, suggest that the delay recovery and the current deactivation are independent processes.

While near the half-activation range the current decays with an apparently single exponential time course, at more positive potentials the current deactivation becomes sigmoidal.

The time course of the delay recovery does not seem to be linked to the time course of current deactivation recorded at the same voltage.
