Acceleration:

Climatology

แปลว่า(Environmental Engineering) The study of the climate, how the earth's atmosphere performs over long periods of time.

Velocity:

แปลว่า(english) A vector quantity equal to the rate that position changes with time.

Calcine

แปลว่า(Concrete Engineering) To alter composition or physical state by heating to a specific temperature for a specific length of time.

Carbonation

แปลว่า(Concrete Engineering) 1) Reaction between the products of portland cement (soluble calcium hydroxides), water and carbon dioxide to produce insoluble calcium carbonate (efflorescence). 2) Soft white, chalky surface dusting of freshly placed, unhardened concrete caused by carbon dioxide from unvented heaters or gasoline powered equipment in an enclosed space. 3) Carbonated, dense, impermeable to absorption, top layer of the surface of concrete caused by surface reaction to carbon dioxide. This carbonated layer becomes denser and deeper over a period of time. 4) Reaction with carbon dioxide which produces a slight shrinkage in concrete. Improves chemical stability. Concrete masonry units during manufacturing may be deliberately exposed to carbon dioxide after reaching 80% strength to induce carbonation shrinkage to make the units more dimensionally stable. Future drying shrinkage is reduced by as much as 30%.

Batch Oven

แปลว่า(english) Oven use to bake a number of cores at one time.
