(14) Hysteresis in the phase transition temperature may be due to the difference in water content of the two phases and their low water permeabilities.
(15) Moreover, the force-aiNa relation observed after increase in stimulation rate from 0.5 to 3 Hz resembled that observed after decrease in the rate from 3 to 0.5 Hz, indicating an absence of hysteresis in the relation.

(20) Bronchodilation results in a constrictor effect of a DI which probably represents relaxation of smooth muscle in conducting airways, thereby decreasing airway hysteresis and allowing parenchymal hysteresis to dominate.
Thermostat
Definition:
(n.) A self-acting apparatus for regulating temperature by the unequal expansion of different metals, liquids, or gases by heat, as in opening or closing the damper of a stove, or the like, as the heat becomes greater or less than is desired.
