Dissolved oxygen (DO)

แปลว่า(Environmental Engineering) The amount of molecular oxygen dissolved in water.

Procaryotic organisms

แปลว่า(Environmental Engineering) Organisms which do not have a cellular membrane.

Bacteria

แปลว่า(Environmental Engineering) One celled microorganisms which do not have a nuclear membrane.

Fixed solids

แปลว่า(Environmental Engineering) (FS) are the solids that do not volatilize at 550°C.

Stability:

แปลว่า(english) Stability is best defined as the opposite of instability, which is the occurrence of large structural deformations which are not the result of material failure.

Anaerobes

แปลว่า(Environmental Engineering) A group of organisms that do not require molecular oxygen. These organisms, as well as all known life forms, require oxygen. These organisms obtain their oxygen from inorganic ions such as nitrate or sulfate or from protein.

Bainite

แปลว่า(english) A eutectoid transformation product of ferrite and a fine dispersion of carbide, generally formed at temperatures below 840 to 930 F (450 to 500 C): upper bainite is an aggregate containing parallel lath-shape units of ferrite, produces the so-called feathery appearance in optical microscopy, and is formed at temperatures above about 660 F (350 C); lower bainite consists of individual plate-shape units and is formed at temperatures below about 660 F (350 C). Also, a slender, needle-like (acicular) microstructure appearing in spring steel strip characterized by toughness and greater ductility than tempered Martensite. Bainite is a decomposition product of Austenite best developed at interrupted holding temperatures below those forming fine pearlite and above those giving Martensite.
