Receiving water quality standards

แปลว่า(Environmental Engineering) Standards which require a discharger to maintain a certain quality level in the receiving water.

Balanced Steel

แปลว่า(english) Steels in which the deoxidisation is controlled to produce an intermediate structure between a rimmed and killed steel, Sometimes referred to as semi-killed steels, they possess uniform properties throughout the ingot and amongst their applications are boiler plate and structural sections.

Cement Gel

แปลว่า(Concrete Engineering) The colloidal gel (glue like) material that makes up the major portion of the porous mass of which hydrated cement paste is composed.

Aluminous Cement

แปลว่า(Concrete Engineering) A hydraulic cement in which the principal constituents are calcium aluminates, instead of calcium silicates which comprise the major ingredients of portland cement. (See calcium aluminate cement)

Rebound

แปลว่า(Concrete Engineering) Wet shotcrete or sand and cement which bounces away from a surface again at which pneumatically applied mortar is being projected.

Conversion

แปลว่า(Environmental Engineering) The fraction of a species entering a system which is converted to product.

Amino acid

แปลว่า(Environmental Engineering) A functional group which consists of a carbon with a carboxylic acid, "-COOH" and an amine, "-NH2." These compounds are the building blocks for proteins.

Boring Tool

แปลว่า(english) A cutting tool in which the tool bit,the boring bar and in some cases the tool holder are incorporated.

Aerobic process

แปลว่า(Environmental Engineering) A process which requires molecular oxygen.

Component (of a vector):

แปลว่า(english) Any vector can be expressed as a collection of vectors whose sum is equal to the original vector. Each vector in this collection is a component of the original vector. It is common to express a vector in terms of components which are parallel to the x and y axes.

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.

Synergism is the act of working together

แปลว่า(Environmental Engineering) Two chemicals which are synergistic have a greater effect together than the sum of their individual effects. The effect can be either positive or negative.
