vacuum-brake

แปลว่าห้ามล้อรถซึ่งใช้ลมดูดอย่างเดียวกับ vacuum and atmospheric brake (แต่เป็นเครื่องห้ามล้อที่ใช้กับขบวนรถไฟ)

Bright Annealed Wire

แปลว่า(english) Steel wire bright drawn and annealed in controlled non-oxidizing atmosphere so that surface oxidation is reduced to a minimum and the surface remains relatively bright.

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.

Bonderized Coating

แปลว่า(english) A thin film of phosphate pretreatment applied to a steel surface (bare or zinc coated) to enhance paintability.

Bright Dipping

แปลว่า(english) Chemical polishing of aluminum, often by treatment with a mixture of nitric acid and phosphoric acid, yielding a mirror-shiny (specular) highly reflective surface. It is almost always followed by anodizing to protect the surface and provide some choice of color.

Greenhouse gases

แปลว่า(Environmental Engineering) Gases which trap solar radiation. Of the solar energy entering the earth's atmosphere a portion is reflected back and a portion penetrates onto the earth's surface. The portion reflected back from the earth's surface is at a different wavelength that when it entered. Carbon dioxide and other gases, which pass solar radiation, absorb this reflected radiation, increasing the earth's temperature. This is much like a greenhouse, hence the name.

Department

แปลว่ากรม, ทบวง, กอง, (ในส่วนราชการ) Depratment of Lands = กรมที่ดิน Department of Land Co-operatuve = กรมสหกรณ์ที่ดิน Department of Mines = กรมโลหะกิจ Department of Public and Municipal Works = กรมโยธาเทศบาล Department of State Higways = กรมทางหลวงแผ่นดิน

Bright Annealing

แปลว่า(english) A process carried out usually in a controlled furnace atmosphere, so surface does not oxidize, remaining bright.

Chlorofluorocarbons

แปลว่า(Environmental Engineering) Synthetic organic compounds used for refrigerants, aerosol propellants (prohibited in the U.S.), and blowing agents in plastic foams. CFCs migrate to the upper atmosphere destroying ozone and increasing global warming. Typical atmospheric residence times are 50 to 200 years.

Burning 2

แปลว่า(english) Heating a metal beyond the temperature limits allowable for the desired heat treatment, or beyond the point where serious oxidation or other detrimental action begins.

pressure, atmospheric

แปลว่าความดันบรรยากาศ : อัตราส่วนระหว่างน้ำหนักของบรรยากาศต่อหนึ่งหน่วยพื้นที่บนผิวโลกมีค่าประมาณ 14.7 ปอนด์ต่อตารางนิ้ว หรือ เป็นความสูง 760 มม. ปรอท หรือ 10 เมตรของน้ำ

Moist Room

แปลว่า(Concrete Engineering) A room used for storing and curing cementitious test specimens. The atmosphere of this room is maintained at a temperature of 73.4 3.0'F or 23.0*1.7'0 and relative humidity of at least 98 percent. These facilities must be adequate to continually maintain free moisture on the exteriors of test specimens.
