Saltwater intrusion

แปลว่า(Environmental Engineering) The gradual replacement of freshwater by saltwater in coastal areas where excessive pumping of groundwater occurs.

Oxidative phosphorylation

แปลว่า(Environmental Engineering) The synthesis of the energy storage compound adenosine triphosphate (ATP) from adenosine diphosphate (ADP) using a chemical substrate and molecular oxygen.

Dump

แปลว่า(Environmental Engineering) An illegal and uncontrolled area where wastes have been placed on or in the ground. See Landfill.

Autotrophs

แปลว่า(Environmental Engineering) A group of organisms capable of obtaining carbon for synthesis from inorganic carbon sources such as carbon dioxide and its dissolved species (the carbonates). This group includes plants and algae.

Chlorofluorocarbons

แปลว่า(Environmental Engineering) Synthetic organic compounds used for refrigerants, aerosol propellants (prohibited in the U.S.), and blowing agents in plastic foams. CFCs migrate to the upper atmosphere destroying ozone and increasing global warming. Typical atmospheric residence times are 50 to 200 years.

Adaptive maintenance

แปลว่า(Software Engineering) activity associate with changing an application to make it conform to changes in its external environment

Dissolved oxygen (DO)

แปลว่า(Environmental Engineering) The amount of molecular oxygen dissolved in water.

Photochemical pollutants

แปลว่า(Environmental Engineering) Chemicals which react photochemically (in the presence of sunlight) to destroy ozone in the stratosphere.

Fluidization

แปลว่า(Environmental Engineering) The suspension of particles by sufficient upward velocity of the fluid. During fluidization the gravity force is overcome by a combination of buoyancy and fluid friction.

CFCs

แปลว่า(Environmental Engineering) Chlorofluorocarbons, chemicals which result in a depletion of the ozone layer in the upper atmosphere.

Closure

แปลว่า(Environmental Engineering) The act of preparing a landfill for long term inactivity, including placement of a cover over the landfill to prevent infiltration of surface water.

Anaerobic process

แปลว่า(Environmental Engineering) A process which only occurs in the absence of molecular oxygen.
