In situ treatment

แปลว่า(Environmental Engineering) Treatment of a waste in place, as opposed to pumping or digging the waste up and then treating it.

Bend Test

แปลว่า(english) Various tests which is used to ascertain the toughness and ductility of a metal product, in which the material is bent around its axis and/ or around an outside radius. A complete test might specify such a bend to be both with and against the direction of grain. For testing, samples should be edge filed to remove burrs and any edgewise cracks resulting from slitting or shearing. If a vice is to be employed, then you must line the jaws with some soft metal, to permit a flow of the metal in the piece being tested.

Box Annealing

แปลว่า(english) Annealing a metal or alloy in a sealed container under conditions that minimize oxidation. In box annealing a ferrous alloy, the charge is usually heated slowly to a temperature below the transformation range, but sometimes above or within it, and is then cooled slowly; this process is also called close annealing or pot annealing.

Tilt-up

แปลว่า(Concrete Engineering) A method of concrete construction such as where members are cast horizontally near their eventual position, usually on a recently placed slab, and then tilted into place after removal of forms.

lengthening rod

แปลว่าก้านต่อเครื่องเจาะ ซึ่งปลายด้านหนึ่งเป็นเกลียวตัวผู้ ปลายอีกด้านหนึ่งเป้นเกลียวตัวเมีย สำหรับต่อด้ามเครื่องมือ เจาะให้ยาวออกไปอีก

Nitrification

แปลว่า(Environmental Engineering) The biological oxidation of ammonia and ammonium sequentially to nitrite and then nitrate. It occurs naturally in surface waters, and can be engineered in wastewater treatment systems. The purpose of nitrification in wastewater treatment systems is a reduction in the oxygen demand resulting from the ammonia.

earthenware

แปลว่าภาชนะที่ทำด้วยดินเผา

Blue Annealing

แปลว่า(english) Heating hot rolled ferrous sheet in an open furnace to a temperature within the transformation range and then cooling in air, in order to soften the metal. The formation of a bluish oxide on the surface is incidental.

Baked Strength

แปลว่า(english) Compressive, shear, tensile or transverse strength of a mold sand mixture when baked at a temperature above 231 B0F (111 B0C) and then cooled to room temperature.

Toxicity

แปลว่า(Environmental Engineering) A U.S. EPA hazardous waste characteristic defined with a rigorous test procedure, the TCLP (for Toxicity Characteristic Leaching Procedure). In the procedure, a waste is extracted for 24 hours with an acetic acid solution. The acid extract is then analyzed for the presence of any of the contaminants listed in the procedure.

osmiridium

แปลว่า(โลหะ) โลหะผสมของออสเมี่ยม (17-487.) และ ridium 497. iวมทั้ง platinum suthenium และ rhodium อย่างละเล็ก ๆ น้อย ๆ เป็นส่วนผสมอยู่ด้วย

naphthenes

แปลว่า(เคมี) คือ Polymethylene hydrocarbons ซึ่งจะพบมากในน้ำมันปิโตรเลี่ยม
