Energy:

แปลว่า(english) A property of a body related to its ability to move a force through a distance opposite the force's direction; energy is the product of the magnitude of the force times the distance. Energy may take several forms: see kinetic energy, potential energy, and elastic energy.

Broach

แปลว่า(english) A long, tapered cutting tool with serrations which,when forced through a hole or across a surface, cuts a desired shape or size.

Bevel

แปลว่า(english) Angle formed between the prepared edge of the end of tube and a plane perpendicular to the surface. Standard pipe bevel is 30 degrees.

water capillary

แปลว่าน้ำดูดซึม : น้ำในดินที่ถูกจับยึดไว้ด้วยแรงดูดซึม (capillary force) ของช่องว่างระหว่างเม็ดดินที่มีขนาดเล็ก เป็นน้ำส่วนที่พืชสามารถนำไปใช้ได้

Brinell Hardness Test

แปลว่า(english) A common standard method of measuring the hardness of materials. The smooth surface of the metal is subjected to indentation by a hardened steel ball under pressure. The diameter of the indentation, in the material surface, is then measured by a microscope and the hardness value is read from a chart or determined by a prescribed formula.

Closure

แปลว่า(Environmental Engineering) The act of preparing a landfill for long term inactivity, including placement of a cover over the landfill to prevent infiltration of surface water.

Load:

แปลว่า(english) An external force. The term load is sometimes used to describe more general actions such as temperature differentials or movements such as foundation settlements.

Transmissibility:

แปลว่า(english) The principle stating that a force has the same external effect on an object regardless of where it acts along its line of action.

Denitrification

แปลว่า(Environmental Engineering) The anoxic biological conversion of nitrate to nitrogen gas. It occurs naturally in surface waters low in oxygen, and it can be engineered in wastewater treatment systems.

Wagner Fineness

แปลว่า(Concrete Engineering) The fineness of materials such as portland cement expressed as total surface area in centimeters per gram as determined by the Wagner turbidimeter apparatus and procedure.
