Transit-Mixed Concrete

แปลว่า(Concrete Engineering) Concrete produced from a central-batching plant, where the materials are proportioned and placed in truck-mixers for mixing enroute to the job or after arrival there.

Stress testing

แปลว่า(Software Engineering) a testing task that determines how software responds when it is forced to meet or exceed operational limits

Ottawa Sand

แปลว่า(Concrete Engineering) A sand used as a standard in testing hydraulic cements by means of mortar test specimens. Sand is produced by processing silica rock particles obtained by hydraulic mining of the orthoquartzite situated in open-pit deposits near Ottawa, Illinois; naturally rounded grains of nearly pure quartz.

Moment:

แปลว่า(english) The resultant of a system of forces causing rotation without translation. A moment can be expressed as a couple.

Reactive waste

แปลว่า(Environmental Engineering) A waste which; 1) reacts violently with water, 2) forms potentially explosive mixtures with water, 3) is normally unstable, 4) contains cyanide or sulfide in sufficient quantity to evolve toxic fumes at high or low pH, 5) is capable of exploding if heated under pressure, or 6) is an explosive compound listed in Department of Transportation (DoT) regulations. One of EPA's four hazardous waste properties.

Backwardation

แปลว่า(english) Market condition where the spot, or current price for a metal is higher than the three-month delivery price. This usually indicates immediate demand is perceived to be stronger than long-term demand. Not considered to be a "normal" market state (See Contango).

Blanking

แปลว่า(english) An early step in preparing flat-rolled steel for use by an end user. A blank is a section of sheet that has the same outer dimensions as a specified part (such as a car door or hood) but that has not yet been stamped. Steel processors may offer blanking for their customers to reduce their labor and transportation costs; excess steel can be trimmed prior to shipment.

Funicular:

แปลว่า(english) A funicular shape is one similar to that taken by a suspended chain or string subjected to a particular loading.

Axial force:

แปลว่า(english) A system of internal forces whose resultant is a force acting along the longitudinal axis of a structural member or assembly.

Quality management

แปลว่า(Software Engineering) a set of software engineering actions that helps ensure that software is built in a way that achieves high quality

Agglomerating Processes

แปลว่า(english) "Fine particles of limestone (flux) and iron ore are difficult to handle and transport because of dusting and decomposition, so the powdery material usually is processed into larger pieces. The raw material's properties determine the technique that is used by mills. 1) SINTER Baked particles that stick together in roughly one-inch chunks. Normally used for iron ore dust collected from the blast furnaces. 2) PELLETS Iron ore or limestone particles are rolled into little balls in a balling drum and hardened by heat. 3) BRIQUETTES Small lumps are formed by pressing material together. Hot Iron Briquetting (HBI) is a concentrated iron ore substitute for scrap for use in electric furnaces.

Greenhouse gases

แปลว่า(Environmental Engineering) Gases which trap solar radiation. Of the solar energy entering the earth's atmosphere a portion is reflected back and a portion penetrates onto the earth's surface. The portion reflected back from the earth's surface is at a different wavelength that when it entered. Carbon dioxide and other gases, which pass solar radiation, absorb this reflected radiation, increasing the earth's temperature. This is much like a greenhouse, hence the name.
