Reversible reaction

แปลว่า(Environmental Engineering) A reaction in which the reactant(s) proceed to product(s), but the products react at an appreciable rate to reform reactant(s).

Elementary reaction

แปลว่า(Environmental Engineering) A reaction in which the rate expression corresponds to the stoichiometric equation.

Irreversible reaction

แปลว่า(Environmental Engineering) A reaction in which the reactant(s) proceed to product(s), but the products react at an appreciable rate to reform reactant(s).

Reaction:

แปลว่า(english) A reaction is a force exerted by a support on an object: sometimes called support reaction. Using this definition, a reaction is an external force.

modulus of subgrade reaction

แปลว่าโมดูลัสการต้านแรงกดของชั้นดิน

Alkali-Aggregate Reaction

แปลว่า(Concrete Engineering) Older terminology for Alkali-Silica Reactivity (ASR).

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.

Basic Oxygen Furnace (BOF)

แปลว่า(english) "WHAT A pear-shaped furnace, lined with refractory bricks, that refines molten iron from the blast furnace and scrap into steel. Up to 30% of the charge into the BOF can be scrap, with hot metal accounting for the rest. WHY BOFs, which can refine a heat (batch) of steel in less than 45 minutes, replaced open-hearth furnaces in the 1950s; the latter required five to six hours to process the metal. The BOF's rapid operation, lower cost and ease of control give it a distinct advantage over previous methods. HOW Scrap is dumped into the furnace vessel, followed by the hot metal from the blast furnace. A lance is lowered from above, through which blows a high-pressure stream of oxygen to cause chemical reactions that separate impurities as fumes or slag. Once refined, the liquid steel and slag are poured into separate containers. "

Pin support:

แปลว่า(english) In two dimensions, a pin support restrains two translation degrees of freedom but does not restrain rotation. When considering reaction forces, a pin support is usually considered to have two force components: one each about the x and y axes respectively.

Statically indeterminate:

แปลว่า(english) A statically indeterminate structure is one where there is more than one distribution of internal forces and/or reactions which satisfies equilibrium.

Statically determinate:

แปลว่า(english) A statically determinate structure is one where there is only one distribution of internal forces and reactions which satisfies equilibrium. In a statically determinate structure, internal forces and reactions can be determined by considering nothing more than equations of equilibrium.

System

แปลว่า(Environmental Engineering) An arbitrarily defined area or volume surrounded by a boundary and possessing specific inputs, outputs, and reactions.
