Biogeochemical cycle

แปลว่า(Environmental Engineering) The cycle of elements through the biotic and abiotic environment.

Vapor Pressure

แปลว่า(Concrete Engineering) The pressure exerted by a vapor that is calculated based upon relative humidity and temperature. The higher the humidity and higher temperature, in degrees Fahrenheit, the greater the vapor pressure exerted.

Work breakdown structure (WBS)

แปลว่า(Software Engineering) the set of work tasks required to build the software; defined as part of the process model

Deoxygenation

แปลว่า(Environmental Engineering) The consumption of oxygen by the different aquatic organisms as they oxidized materials in the aquatic environment.

Stiffness:

แปลว่า(english) This is a general term which may be applied to materials or structures. When a force is applied to a structure, there is a displacement in the direction of the force; stiffness is the ratio of the force divided by the displacement. High stiffness means that a large force produces a small displacement. When discussing the stiffness of a material, the concept is the same, except that stress substitutes for force, and strain substitutes for displacement; see modulus of elasticity.

Elastic energy:

แปลว่า(english) The energy stored in deformed elastic material (e.g., a watch spring). Elastic energy equals where k is the stiffness, and is the associated deflection. Elastic energy is sometimes called elastic potential energy because it can be recovered when the object returns to its original shape; see potential energy.

Organic compound

แปลว่า(Environmental Engineering) Any compound containing carbon except for the carbonates (carbon dioxide, the carbonates and bicarbonates), the cyanides, and cyanates.

Linear:

แปลว่า(english) A structure is said to behave linearly when its the deformation response is directly proportional to the loading (i.e. doubling the load doubles the displacement response). For a material, linear means that the stress is directly proportional to the strain.

Influent

แปลว่า(Environmental Engineering) The fluid entering a system, process, tank, etc. An effluent from one process can be an influent to another process. See effluent.

Bauxite

แปลว่า(english) The only commercial ore of aluminum, corresponding essentially to the formula Al2O3xH2O.

Blow

แปลว่า(english) The impact or force delivered by one workstroke of the forging equipment.

Troposphere

แปลว่า(Environmental Engineering) The lower atmosphere, from the earth's surface to approximately 12 km. This portion of the earth's atmosphere contains about 95 percent of the atmospheric gases. The temperature gradually declines through this region.
