Water Vapor Pressure

แปลว่า(Concrete Engineering) The pressure exerted by water vapor. Air that contains higher amounts of water vapor exerts a higher vapor pressure than air which has a lower amount of has a higher water vapor pressure In concrete water vapor pressure is calculated by the difference between the vapor pressure of the concrete and the ambient relative humidity and temperature and in contact with the soil. that is calculated by; based upon relative humidity and temperature. The greater the difference between the water vapor and ambient humidity and temperature, in degrees Fahrenheit. the greater the water vapor pressure exerted.

Blister 2

แปลว่า(english) A defect in metal, on or near the surface, resulting from the expansion of gas in a subsurface zone. Very small blisters are called pinheads or pepper blisters.

Suspended growth reactor

แปลว่า(Environmental Engineering) A reactor in which the microorganisms are suspended in the wastewater. Examples of suspended growth reactors are activated sludge reactors and anaerobic digesters. See attached growth reactor.

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.

Electronegativity

แปลว่า(Environmental Engineering) The potential of an atom to attract electrons when the atom is bonded in a compound. The scale is 0 to 4 with 0 being the most electropositive (low attraction) and 4 being the most electronegative (high attraction).

Interface design

แปลว่า(Software Engineering) a software engineering action that establishes the structure and workflow for a user interface; follows three "golden rules:" place the user in control, reduce the user's memory leoad, make the interface consistent.

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.

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.

Block Off

แปลว่า(english) 1) Wooden separators which are used at both the bottom of a lift and between IPM's (bundles) of a lift. 2) The act of placing 4x4s between the lifts in the piler's box.

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.

Air Entraining Agent

แปลว่า(Concrete Engineering) An addition for hydraulic cement, or an admixture for concrete or mortar which entrains air in the form of minute bubbles in the concrete or mortar during mixing.
