Bending Strength

แปลว่า(english) Upper limit of normal stress of a beam at which fracture or excessive plastic deformation occurs.

Ligand

แปลว่า(Environmental Engineering) The ion or molecule which surrounds or complexes with the central atom or ion.

Blue Vitriol Copper sulfate

แปลว่า(english) A layout solution which turns a copper color when applied to a clean,polished metal surface.

ACCUMULATOR

แปลว่า(english) A vessel, normally cylindrical, which is used to store fluid and gas for future release of the energy in the compressed fluid and gas. Normally contains a diaphragm or piston between the fluid (liquid) and gas chambers. Fluid is normally introduced at one end and the gas at the opposite end.

Thiols

แปลว่า(Environmental Engineering) Organic compounds which contain the "-SH" functional group. Also called mercaptans.

Maximum Size Aggregate

แปลว่า(Concrete Engineering) Aggregate whose largest particle size is present in sufficient quantity to affect the physical properties of concrete; generally designated by the sieve size on which the maximum amount permitted to be retained is 5 or 10 percent by weight.

Coupling

แปลว่า(Software Engineering) an informal measure of the degree to which a software component is connected to other components, to data, and to the external environment

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.

Equivalent

แปลว่า(Environmental Engineering) The mass of the compound which will produce one mole of available reacting substance. Thus, for an acid, this would be the mass of acid which will produce one mole of H+, for a base, one mole of OH-.

Trickling filter

แปลว่า(Environmental Engineering) An attached growth biological process in which the microbial film is attached to non-moving rock or plastic media.

Heterotrophic

แปลว่า(Environmental Engineering) A group of organisms which obtain carbon for synthesis from other organic matter or proteins.

Stiffness:

แปลว่า(english) This is a general term which may be applied to materials or structures. When a force is applied to a structure, there is a displacement in the direction of the force; stiffness is the ratio of the force divided by the displacement. High stiffness means that a large force produces a small displacement. When discussing the stiffness of a material, the concept is the same, except that stress substitutes for force, and strain substitutes for displacement; see modulus of elasticity.
