The charge is normally heated slowly to a temperature below the transformation range, but occasionally above or within it, and then is slowly cooled.

Nitrification

แปลว่า(Environmental Engineering) The biological oxidation of ammonia and ammonium sequentially to nitrite and then nitrate. It occurs naturally in surface waters, and can be engineered in wastewater treatment systems. The purpose of nitrification in wastewater treatment systems is a reduction in the oxygen demand resulting from the ammonia.

Change of State

แปลว่า(Concrete Engineering) The process whereby liquid is heated to the point of evaporation changing the liquid into a gas the condensation of a gas on a cooler surface returning it from gaseous to liquid form.

Design walkthrough

แปลว่า(Software Engineering) a formal technical review of the design

Band, Inside

แปลว่า(english) A loose steel frame placed inside a removable flask to reinforce the sand at the parting line after the flask has been removed.

Biochemical oxygen demand (BOD)

แปลว่า(Environmental Engineering) The amount of oxygen required to oxidize any organic matter present in a water during a specified period of time, usually 5 days. It is an indirect measure of the amount of organic matter present in a water.

Line of Action:

แปลว่า(english) The line of action of a force is the infinite line defined by extending along the direction of the force from the point where the force acts.
