Deflection:

แปลว่า(english) This word usually carries the same meaning as displacement, although it is sometimes used in place of deformation.

Chemical oxygen demand (COD)

แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any organic matter in the water using harsh chemical conditions.

Banding

แปลว่า(english) Inhomogeneous distribution of alloying elements or phases aligned in filaments or plates parallel to the direction of working.

Dump

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

Inertial Force:

แปลว่า(english) A fictitious force used for convenience in visualizing the effects of forces on bodies in motion. For an accelerating body, the inertial force is considered as a body force whose resultant acts at the object's center of gravity in a direction opposite the acceleration. The magnitude of the force is the mass of the object times the magnitude of the acceleration.

Biochemical oxygen demand (BOD)

แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any organic matter present in a water during a specified period of time, usually 5 days. It is an indirect measure of the amount of organic matter present in a water.

Boron Steels

แปลว่า(english) The addition of boron in the range 0.0005-0.005% to certain steels increases the hardenability. A range of boron steels is now listed in the current BS 970 and are widely used for the production of cold headed fastenings.

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.

Backoff

แปลว่าRemoval of part of coil from entry end of unit; may be necessitated by a defect in coil or by a wreck in the mill, etc. Backoff weight is the part of the coil that is removed and not finished/produced.

Brown Sharp Gages

แปลว่า(english) A standard series of sizes refered to by numbers, in which the diameter of wire or thickness of sheet metal is generally produced and which is used in the manufacture of brass, bronze, copper, copper-base alloys and aluminum. These gage numbers have a definite relationship to each other. In this system, the decimal thickness is reduced by 50% every six gage numbers- while temper is expressed by the number of B&S gage numbers as cold reduced in thickness from previous annealing. For each B&S gage number in thickness reduction, where is assigned a hardness value of 1/4 hard.

Elastic Shortening

แปลว่า(Concrete Engineering) The shortening of a member in pre-stressed concrete which occurs on the application of forces induced by prestressing.

BREATHER

แปลว่า(english) A device which permits air to move in and out of a container or component to maintain atmospheric pressure.
