Выражение встречается в следующем контексте:
Due to the fact the drying phase ahs started it is compulsory that all this humidity is supplied by the drying timber, It is therefore useful to slowly increase the temperature from To to T1 (with the exception for the cases with fungus) but it is also better to inhibit the intervention of the humidification. The equipment forecast for the management and control
of the drying cycle must have a suitable “hysteresis” which delays the intervention of humidification).
