Phototroph

แปลว่า(Environmental Engineering) Organisms which obtain energy from light using photooxidation.

Chemotroph

แปลว่า(Environmental Engineering) Organisms which obtain energy from the metabolism of chemicals, either organic or inorganic.

Heterotrophic

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

Bright Dip

แปลว่า(english) An acid solution into which pieces are dipped in order to obtain a clean, bright surface.

Autotrophic

แปลว่า(Environmental Engineering) Organisms which utilize inorganic carbon for synthesis of protoplasm. Ecologists narrow the definition further by requiring that autotrophs obtain their energy from the sun. In microbiologist parlance, this would be a photoautotroph. See photoautotrophic and chemoautotrophic.

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.

Batch Anneal

แปลว่า(english) The process by which a large, stationary stack of steel coils (4 coils high) is subjected to a long heat-treating cycle. This process enables the cold-rolled sheet to fully recrystallize into the softest possible product conforming to customer specifications. Controlling the recrystallization process makes a fine-grained microstructure easy to obtain, and minimizes the tendencies for retention of directional properties of the rolled steel which could produce undesirable shapes in the stamping of a cylindrical part such as a can. Also see Anneal and Continuous Anneal.
