Terms for subject Environment (26921 entries)
surface source diffuse Quelle
surface source Emissionsquelle
surface storage oberirdische Speicherung
surface tension (The force acting on the surface of a liquid, tending to minimize the area of the surface; quantitatively, the force that appears to act across a line of unit length on the surface. Also known as interfacial force; interfacial tension; surface intensity) Oberflächenspannung
surface tension of water Oberflächenspannung des Wassers
surface treatment (Any method of treating a material (metal, polymer, or wood) so as to alter the surface, rendering it receptive to inks, paints, lacquers, adhesives, and various other treatments, or resistant to weather or chemical attack) Oberflächenbehandlung
surface treatment with washing Oberflächenbehandlung mit Waschen
surface water Oberflächengewässer
surface water Oberflächengewasser
surface water oberirdische Gewässer (pl.)
surface water (All waters on the surface of the Earth found in streams, rivers, ponds, lakes, marshes or wetlands, and as ice and snow) Oberflächengewasser
surface water containment Kontrolle von Oberflächengewässern
surface water management Oberflächenwasserbewirtschaftung
surface water management (The administration or handling of water naturally open to the atmosphere (rivers, lakes, reservoirs, ponds, streams, seas, etc.)) Oberflächenwasserbewirtschaftung
Surface Water Quality Monitoring Beobachtung der Oberflächengewässer-Qualität
surface waters Oberflächenwasser
surface waters oberirdische Gewässer (pl.)
surface-active agent grenzflächenaktive Substanz
surface-active agent (A substance that, when used in small quantities, modifies the surface properties of liquids or solids. A surface-active agent reduces surface tension in a fluid or the interfacial tension between two immiscible fluids, such as oil and water. Surfactants are particularly useful in accomplishing the wetting or penetration of solids by aqueous liquids and serve in the manner of detergent, emulsifying, or dispersing agents. They are more effective than soap in certain situations and are used by conservators for such purposes as cleaning, wetting, and dispersing) Tensid
surfactant grenzflächenaktive Substanz
