Errors

แปลว่า(Software Engineering) a lack of conformance found before software is delivered to the customer

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.

Dry Rodded Weight

แปลว่า(Concrete Engineering) The weight of dry aggregate rodded into a cylindrical container of diameter approximately equal to the height, each of 3 layers rodded 25 times, and the excess aggregate struck off level with the top of the container

Cold Joint

แปลว่า(Concrete Engineering) A visible lineation which forms when the placement of concrete is delayed. The concrete in place hardens prior to the next placement of concrete against it.

Mass balance

แปลว่า(Environmental Engineering) An organized accounting of all inputs and outputs to an arbitrary but defined system. Stated in other terms, the rate of mass accumulation within a system is equal to the rate of mass input less the rate of mass output plus the rate of mass generation within the system.

Bleeding, Bleed Water

แปลว่า(Concrete Engineering) A form of segregation in which some of the water in a mix tends to rise to the surface of freshly placed concrete. Known also as water gain.

Attached growth reactor

แปลว่า(Environmental Engineering) A reactor in which the microorganisms are attached to engineered surfaces within the reactor. Examples of attached growth reactors are the trickling filter and the rotating biological contactor. See suspended growth reactor.

Flexibility:

แปลว่า(english) Flexibility is the inverse of stiffness. When a force is applied to a structure, there is a displacement in the direction of the force; flexibility is the ratio of the displacement divided by the force. High flexibility means that a small load produces a large displacement.

Backer (back-up plate)

แปลว่า(english) A “tool” or reinforcing part, which presses against the outer surface of an extrusion die, supporting it against the pressure of the extruding metal. The backer has an opening larger than the die aperture, allowing the extruded product to emerge without marring its soft surface.

Back Gears

แปลว่า(english) Gears fitted to a machine to increase the number of spindle speeds obtainable with a cone or step pulley belt drive.

Statically equivalent:

แปลว่า(english) Two force systems are statically equivalent when their resultants are equal. Physically, this means that the force systems tend to impart the same motion when applied to an object; note that the distribution of resulting internal forces in the object may be different.

Back Rake

แปลว่า(english) The angular surface ground back from the cutting edge of cutting tools. On lathe cutting tools. The rake is positive if the face slopws down from the cutting edge toward the shank, and negative if the face sloopes upward toward the shank.
