Anaerobes

แปลว่า(Environmental Engineering) A group of organisms that do not require molecular oxygen. These organisms, as well as all known life forms, require oxygen. These organisms obtain their oxygen from inorganic ions such as nitrate or sulfate or from protein.

Bleeder

แปลว่า(english) A defect wherein a casting lacks completeness due to moltn metal draining or leaking out of some part of the mold cavity after pouraing has stopped.

Breakout

แปลว่า(english) An accident caused by the failure of the walls of the hearth of the furnace resulting in liquid iron or slag (or both) flowing uncontrolled out of the blast furnace.

Concentrated force:

แปลว่า(english) A force considered to act along a single line in space. Concentrated forces are useful mathematical idealizations, but cannot be found in the real world, where all forces are either body forces acting over a volume or surface forces acting over an area.

Mass balance

แปลว่า(Environmental Engineering) An organized accounting of all inputs and outputs to an arbitrary but defined system. Stated in other terms, the rate of mass accumulation within a system is equal to the rate of mass input less the rate of mass output plus the rate of mass generation within the system.

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.

Blast Furnace 2

แปลว่า(english) A vertical shaft type smelting furnace in which an air blast is used, usually hot, for producing pih iron. The furnace is continuous in operation using iron ore, coke, and limestone as raw materials which are charged at the top while the molten iron and slag are collected at the bottom and are tapped out at intervals.

Bent Axis Pumps

แปลว่า(english) In this pump, the pistons are at an angle to the drive shaft and Thrust Plate. The piston block shaft is connected to the drive shaft by a universal joint, not shown. The drive shaft, thrust plate, piston block shaft, and piston block all revolve. The connecting rods are attached to the thrust plate and revolve with it, unlike the swash plate pump where the piston rods slide past a stationary swash plate. The outlet ports are semi-circular holes in the Valve Plate, shown on the far right of the animation on edge and in a head-on view below, right. As the pump revolves, half the pistons suck in fluid as they pass over the intake port. The other pistons discharge their fluid through the outlet port. This pump should be compared to the radial piston pump, swash plate pump, and wobble pump.
