Metabolism

แปลว่า(Environmental Engineering) The processes which sustain an organism, including energy production, synthesis of proteins for repair and replication.

Rock Pocket

แปลว่า(Concrete Engineering) Area or portion of hardened concrete which is deficient in mortar and consisting primarily of coarse aggregate and open voids; caused by insufficient consolidation or separation during placement, or both; by leakage from form.

Linear Elastic:

แปลว่า(english) A force-displacement relationship which is both linear and elastic. For a structure, this means the deformation is proportional to the loading, and deformations disappear on unloading. For a material, the concept is the same except strain substitutes for deformation, and stress substitutes for load.

Colloids

แปลว่า(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.

Photochemical pollutants

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

Break Test (for tempered steel)

แปลว่า(english) A method of testing hardened and tempered high carbon spring steel strip wherein the specimen is held and bent across the grain in a vice-like calibrated testing machine. Pressure is applied until the metal fractures at which point a reading is taken and compared with a standard chart of brake limitations for various thickness ranges.

Anaerobic process

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

Ac3

แปลว่า(english) In hypoeutectoid steel, the temperature at which transformation of ferrite into austenite is completed upon heating.

Bandsaw

แปลว่า(english) A power saw, the blade of which is a continuous,narrow,steel band having teeth on one edge and passing over two large pulley wheels.

Source reduction

แปลว่า(Environmental Engineering) The elimination or reduction of the waste at the source by modification of the actual process which produces the waste.

Bending Angle

แปลว่า(english) A 'V-shaped' piece of angle iron attached to the rear of the coil car in the Strip Steel, which is used to help the operator put bends into the front end of a coil.

Irreversible reaction

แปลว่า(Environmental Engineering) A reaction in which the reactant(s) proceed to product(s), but the products react at an appreciable rate to reform reactant(s).
