Condensation

แปลว่า(Concrete Engineering) When a moisture laden gas comes in contact with a cooler surface a change of state from gaseous to liquid occurs.

Colloids

แปลว่า(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.

Burnt Rubber

แปลว่า(english) Small or large black spots that generally show up on surface and are generally caused by pickling steel too hot.

Boil

แปลว่า(english) Agitation of a bath of metal caused by the liberation of a gas beneath its surface. May be deliberately induced by the addition of oxidizing material to a bath containing excess carbon. In the later case it is called a carbon boil and CO or CO2 are liberated.

Closure

แปลว่า(Environmental Engineering) The act of preparing a landfill for long term inactivity, including placement of a cover over the landfill to prevent infiltration of surface water.

Troposphere

แปลว่า(Environmental Engineering) The lower atmosphere, from the earth's surface to approximately 12 km. This portion of the earth's atmosphere contains about 95 percent of the atmospheric gases. The temperature gradually declines through this region.

Bevel

แปลว่า(english) Angle formed between the prepared edge of the end of tube and a plane perpendicular to the surface. Standard pipe bevel is 30 degrees.

Pining

แปลว่า(Concrete Engineering) Development of relatively small cavities in a concrete surface, due to phenomena such as cavitation or corrosion.

Peeling

แปลว่า(Concrete Engineering) A process in which thin flakes of matrix or mortar are broken away from concrete surface; caused by adherence of surface mortar-to forms as forms are removed, or to trowel or float in portland cement plaster.

Burn-On-Sand

แปลว่า(english) Sand adhering to the surface of the casting that is extremely difficult to remove.

Breaker

แปลว่า(english) Uncoiler rolls through which the strip passes; composed of a mandrel and leveling rolls which unwind the strip prior to processing through the Pickler. Breaker rolls assist in breaking up the Hot Mill surface scale.

Concentrated force:

แปลว่า(english) A force considered to act along a single line in space. Concentrated forces are useful mathematical idealizations, but cannot be found in the real world, where all forces are either body forces acting over a volume or surface forces acting over an area.
