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.

Magnitude:

แปลว่า(english) A scalar value having physical units.

Risk Management and Monitoring Plan (RMMP)

แปลว่า(Software Engineering) a plan for mitigating, monitoring and managing risks

Organic nitrogen

แปลว่า(Environmental Engineering) Nitrogen contained as amines in organic compounds such as amino acids and proteins.

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.

Nitrogen fixation

แปลว่า(Environmental Engineering) The conversion of atmospheric (or dissolved) nitrogen gas into nitrate by microorganisms.

unit hydrograph

แปลว่ากราฟหนึ่งหน่วยน้ำท่า : ดู hydrograph, unit

Denitrification

แปลว่า(Environmental Engineering) The anoxic biological conversion of nitrate to nitrogen gas. It occurs naturally in surface waters low in oxygen, and it can be engineered in wastewater treatment systems.

Unit Water Content

แปลว่า(Concrete Engineering) The quantity of water per unit volume of freshly mixed concrete, often expressed as gallons or pounds per cubic yard. This is the quantity of water on which the water cement ratio is based, and does not include water absorbed by the aggregate

Non-agitating Unit

แปลว่า(Concrete Engineering) A truck-mounted unit for transporting ready-mixed concrete short distances, not equipped to provide agitation (slow mixing) during delivery.

nitrate

แปลว่ากรดดินประสิวที่รวมกับธาตุอื่นๆ เช่น รวมกับโปแตสเซี่ยม ก็เป็น potassium nitrate

zenith

แปลว่าจุดที่ตรงศีระบนท้องฟ้า
