Billet

แปลว่า(english) (1) A semi-finished section hot rolled from a metal ingot, with a rectangular cross section usually ranging from 16 to 36 in., the width being less than twice the thickness. Where the cross section exceeds 36 in., the term “bloom” is properly but not universally used. Sizes smaller than 16 in. are usually termed “bars”; a solid semi-finished round or square product which has been hot worked by forging, rolling, or extrusion. (2) A semi-finished, cogged, hot rolled or continuous-cast metal product of uniform section, usually rectangular with radiused corners. Billets are relatively larger than bars.

relative density

แปลว่าความหนาแน่นสัมพัทธ์

Pining

แปลว่า(Concrete Engineering) Development of relatively small cavities in a concrete surface, due to phenomena such as cavitation or corrosion.

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.

Process framework

แปลว่า(Software Engineering) a relatively small set of fundamental software engineering activities that define a software process

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.

relative motion

แปลว่าแรงเคลื่อนที่สัมพันธ์กัน

relative humidity (1)

relative

แปลว่าสัมพัทธ์

Vapor Pressure

แปลว่า(Concrete Engineering) The pressure exerted by a vapor that is calculated based upon relative humidity and temperature. The higher the humidity and higher temperature, in degrees Fahrenheit, the greater the vapor pressure exerted.

Water Vapor Pressure

แปลว่า(Concrete Engineering) The pressure exerted by water vapor. Air that contains higher amounts of water vapor exerts a higher vapor pressure than air which has a lower amount of has a higher water vapor pressure In concrete water vapor pressure is calculated by the difference between the vapor pressure of the concrete and the ambient relative humidity and temperature and in contact with the soil. that is calculated by; based upon relative humidity and temperature. The greater the difference between the water vapor and ambient humidity and temperature, in degrees Fahrenheit. the greater the water vapor pressure exerted.

Bars

แปลว่า(english) A relatively long straight, rigid piece pf metal; long steel products rolled from billets into such shapes as squares,rectangles, rounds,angles,channels,hexagons,and tees. In steel, “merchant bars” include rounds,flats,angles,squares,and channels that are used by fabricators to manufacture a wide variety of products such as furniture,stair railings and farm equipment. Concrete reinforcing bar (rebar) is used to strengthen concrete in highways,bridges and buildings.
