Pumping

pumping

[′pəmp·iŋ] (fluid mechanics) Unsteadiness of the mercury in the barometer, caused by fluctuations of the air pressure produced by a gusty wind or due to the motion of a vessel. (physics) The application of optical, infrared, or microwave radiation of appropriate frequency to a laser or maser medium so that absorption of the radiation increases the population of atoms or molecules in higher energy states. Also known as electronic pumping. The removal of gases and vapors from a vacuum system.

Pumping

(in quantum electronics), the process of creation of a nonequilibrium state of a substance under the action of electromagnetic fields or collisions with charged or neutral particles, upon abrupt cooling of preheated gaseous masses, and so on. Pumping may shift a substance from a state of thermal equilibrium to an active state (with a population inversion), in which it can amplify and generate electromagnetic waves.

The term “pumping” has spread beyond the bounds of quantum electronics—it is used in radio engineering and optics to designate the processes by which the active elements of parametric systems are affected.

pumping

The displacement and ejection of water and suspended fine particles at joints, cracks, and edges.

Drug slang A regional term for selling crack
Sexology Copulation

pump·ing

(pŭmp'ing) Vigorous opening and closing of the fist to enhance filling of subcutaneous veins below a tourniquet placed around an arm in preparation for phlebotomy.

pumping

(pump'ing) Draining or emptying of fluids by hydraulic suction.

lymphatic pumping

In osteopathy, manipulation of the thoracic cavity to facilitate lymphatic circulation.
