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

Vibration

แปลว่า(Concrete Engineering) Energetic agitation of concrete to assist in its consolidation, produced by mechanical oscillating devices at moderately high frequencies. (A.) External vibration employs a device attached to the forms and is particularly applicable to the manufacture of precast items and for the vibration of tunnel lining forms. (B.)

Bismuth

แปลว่า(english) Chemical symbol Bi. A soft, course cystalline heavy metal with a silvery white color and pinkish tinge; usually produced as a by-product of copper,leaad and other metals. Has a thermal conductivity lower than all other metals except mercury. Used as alloying agent but leading use is in pharmaceuticals.

Brown Sharp Gages

แปลว่า(english) A standard series of sizes refered to by numbers, in which the diameter of wire or thickness of sheet metal is generally produced and which is used in the manufacture of brass, bronze, copper, copper-base alloys and aluminum. These gage numbers have a definite relationship to each other. In this system, the decimal thickness is reduced by 50% every six gage numbers- while temper is expressed by the number of B&S gage numbers as cold reduced in thickness from previous annealing. For each B&S gage number in thickness reduction, where is assigned a hardness value of 1/4 hard.

Bounding

แปลว่า(Software Engineering) removing ambiguity from specification

Broaching

แปลว่า(english) Smoothing machined holes or outside surfaces of castings by drawing pushing on or more broaches (special cutting tools) through the roughed out hole.
