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.

Boiler

แปลว่า(english) A closed vessel in which water, is transformed into steam at a given pressure and temperature under controlled conditions.

Trickling filter

แปลว่า(Environmental Engineering) An attached growth biological process in which the microbial film is attached to non-moving rock or plastic media.

Secondary treatment

แปลว่า(Environmental Engineering) In wastewater treatment, the conversion of the suspended, colloidal and dissolved organics remaining after primary treatment into a microbial mass with is then removed in a second sedimentation process. Secondary treatment included both the biological process and the associated sedimentation process.

Stratosphere

แปลว่า(Environmental Engineering) The atmosphere from approximately 12 km to 70 km. The temperature of the atmosphere increases in this region.Strong acid

Bolster (die block)

แปลว่า(english) A “tool” or reinforcing part which supports the backer-which, in turn, supports an extruding die against the pressure of extrusion.

Blacking Hole

แปลว่า(english) Irregular-shaped surface cavities in a casting containing carbonaceous matter. Caused by spilling off of the blacking from the mold surface.
