There are several processes and phenomena within the world, that are subjected throughout their development to the shortrun external influences. Their length is negligible compared with the entire length of the studied phenomena and processes. Therefore, it are often assumed that these external effects are “instantaneous”, i.e. they're within the kind of impulses. The investigation of such “leaps and bounds” developing resurgent states may be a subject of various sciences: mechanics, management theory, pharmacology, medical specialty, population dynamics, economics, ecology.
