Anoxic process

แปลว่า(Environmental Engineering) A process which occurs only at very low levels of molecular oxygen or in the absence of molecular oxygen.

Stratosphere

แปลว่า(Environmental Engineering) The atmosphere from approximately 12 km to 70 km. The temperature of the atmosphere increases in this region.Strong acid

Blacking Hole

แปลว่า(english) Irregular-shaped surface cavities in a casting containing carbonaceous matter. Caused by spilling off of the blacking from the mold surface.

Formal technical reviews

แปลว่า(Software Engineering) a structured meeting conducted by software engineering with the intent of uncovering errors in some deliverable or work product

HRM High Reactivity Metakaolin

แปลว่า(Concrete Engineering) Refined form of an ASTM C618, Class N (natural) pozzolan. A high performance, mineral admixture, similar in performance to silica fume, additionally comparable in cost. Pure white powdered in form will, not effect the natural color or darken concrete as silica fume does. Suitable for high-performance color matching in architectural concrete. Dosage at 5% to 10%, of cement by weight. No bleed water, better finishability, more creamy, cleanup is easier with slightly higher 28 day strengths and 25% - 35% less plasticizer is required than silica fume.

Bolster (die block)

แปลว่า(english) A “tool” or reinforcing part which supports the backer-which, in turn, supports an extruding die against the pressure of extrusion.

Beam and Sling

แปลว่า(english) Tackle used in conjunction with a crane for turning over the cope or drag of a mold prior to assembly.

Change control

แปลว่า(Software Engineering) an umbrella process that enables a project team to accept, evaluate, and act on changes in a systematic manner

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.

Support:

แปลว่า(english) A support contributes to keeping a structure in place by restraining one or more degrees of freedom. In a structural model, supports represent boundary entities which are not included in the model itself, e.g., foundations, abutments, or the earth itself. For each restrained translation degree of freedom at a support, there is a corresponding reaction force; for each restrained rotation degree of freedom, there is a reaction moment.

Backing Sand

แปลว่า(english) The bulk of the sand in the flask. The sand compacted on top of the facing sand that covers the pattern.

Zircon

แปลว่า(english) The mineral zircon silicate, ZrSiO4, a very high melting point acid refractory material used as a molding material in steel foundries.
