Entrained Air (See air entrainment)

แปลว่า(Concrete Engineering) Microscopic air bubbles intentionally incorporated in mortar or concrete, to improve workability and durability (usually imparting a higher degree of resistance to freezing and thawing).

Roller support:

แปลว่า(english) In two dimensions, a roller support restrains one translation degree of freedom.

Quality

แปลว่า(Software Engineering) the degree to which a product conforms to both explicit and implicit requirements

Defect removal efficiency (DRE)

แปลว่า(Software Engineering) a nondimension ratio (between 0 and 1) that provides an indication of the degree to which errors are removed from software before it is released to end-users

Levels of abstraction

แปลว่า(Software Engineering) the degree of detail with which some representation of the software is presented

Maintainability

แปลว่า(Software Engineering) the degree to which a program is amenable to change

Brake Press Bending

แปลว่า(english) An operation which produces various degree bends when fabricating parts from steel.

Composting

แปลว่า(Environmental Engineering) The controlled aerobic degradation of organic wastes into a material which can be used for landscaping, landfill cover, or soil conditioning.

Consistency

แปลว่า(Concrete Engineering) The degree of plasticity of fresh concrete or mortar The normal measure of consistency is slump for concrete and flow for mortar.

Black Oil Tempered Spring Steel Strip (Scaleless Blue)

แปลว่า(english) A flat cold rolled usually .70/.80 medium high carbon steel strip, blue-black in color, which has been quenched in oil and drawn to desired hardness. While it looks and acts much like blue tempered spring steel and carries a Rockwell hardness of C44/47, it has not been polished and is lower in carbon content. Used for less exacting requirements than clock spring steel, such as snaps, lock springs, hold down springs, trap springs, etc. It will take a more severe bend before fracture than will clock spring, but it does not have the same degree of spring-back.

Support:

แปลว่า(english) A support contributes to keeping a structure in place by restraining one or more degrees of freedom. In a structural model, supports represent boundary entities which are not included in the model itself, e.g., foundations, abutments, or the earth itself. For each restrained translation degree of freedom at a support, there is a corresponding reaction force; for each restrained rotation degree of freedom, there is a reaction moment.

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.
