ASR - Alkali-Silica Reactivity

แปลว่า(Concrete Engineering) The reaction of aggregates, which contain some form of silica or carbonates with sodium oxides or potassium oxides in cement, particularly in warm, moist climates or environments, causing expansion, cracking or popouts in concrete.

Bed-In

แปลว่า(english) Method whereby drag may be rammed in the pit or flask without necessity of rolling over. Process used in production of heavy castings.

Vector:

แปลว่า(english) A mathematical entity having a magnitude and a direction in space.

Mixed liquor volatile suspended solids (MLVSS)

แปลว่า(Environmental Engineering) The volatile suspended solids concentration in the activated sludge tank.

Jacking Equipment

แปลว่า(Concrete Engineering) In prestress concrete, the device used to stress the tendons.

Blowhole

แปลว่า(english) A defect in a casting caused by trapped steam or gas.

Mixed liquor suspended solids (MLSS)

แปลว่า(Environmental Engineering) The total suspended solids concentration in the activated sludge tank.

Total dissolved solids

แปลว่า(Environmental Engineering) (TDS) is the amount of dissolved matter in the water.

Blue Annealing

แปลว่า(english) Heating hot rolled ferrous sheet in an open furnace to a temperature within the transformation range and then cooling in air, in order to soften the metal. The formation of a bluish oxide on the surface is incidental.

Classes - a basic construct in object

แปลว่า(Software Engineering) oriented methods that categorizes elements of the problem

Aging 2

แปลว่า(english) A change in properties that occurs at ambient or moderately elevated temperatures after hot working or a heat treating operation (quench aging in ferrous alloys), or after a cold working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but does not involve a change in chemical composition. In a metal or alloy, a change in properties that generally occurs slowly at room temperature and more rapidly at higher temperatures.

Boron (chemical symbol B)

แปลว่า(english) Element N. 5 of the periodic system. Atomic weight 10.82. It is gray in color, ignites at about 1112 (degrees) F. and burns with a brilliant green flame, but its melting point in a non-oxidizing atmosphere is about 4000 (degrees) F. Boron is used in steel in minute quantities for one purpose only- to increase the hardenability as in case hardening and to increase strength and hardness penetration.
