Beryllium Copper
แปลว่า(english) An alloy of copper and 2-3% beryllium with optionally fractional percentages of nickel or cobalt. Alloys of this series show remarkable age-hardening properties and an ultimate hardness of about 400 Brinell (Rockwell C43). Because of such hardness and good electrical conductivity, beryllium-copper is used in electrical switches, springs, etc.
ultimate strength
แปลว่ากำลังประลัย
Ultimate disposal
แปลว่า(Environmental Engineering) The process of returning residuals back to the environment in a form which will have the minimal or reduced negative environmental impacts.
AAC - Autoclaved Aerated Concrete
แปลว่า(Concrete Engineering) Exceptionally lightweight precast concrete with high thermal qualities and fire resistence. Suitable for cutting with ordinary hand tools. Mix design is composed of portland cement, sand or siliceous material, lime, gypsum, finely powdered aluminum, and water. Initial mix is a combination of portland cement, sand, lime and gypsum to produce a slurry. Finely powdered aluminum mixed into a paste is added prior to placement into large, rail-like forms. The finely powdered aluminum reacts with the alkaline components of the cement and lime to produce hydrogen gas, which increases the volume approximately five times producing a uniformly, dispersed cellular structure. Units are cut to required shape. Units are placed in an autoclave, an enclosed pressurized chamber, and steam cured at 3500 F. Approximately 80% of the ultimate volume consists of air voids.
Retempering
แปลว่า(Concrete Engineering) The addition of water and remixing of concrete which has started to stiffen: usually not allowed as it may affect the ultimate strength.
ultimate stress
แปลว่า(วิศว) แรงประลัย, คือแรงที่ถูกดึงจนวัตถุทนต่อไปไม่ไหว
ultimate load
แปลว่าน้ำหนักบรรทุกประลัย
ultimate load desing
แปลว่าโครงสร้างเหล็กที่ใช้กับงานคอนกรีต
GFRC - Glass Fiber Reinforced Concrete
แปลว่า(Concrete Engineering) Concrete panels, usually architectural designs, reinforced with a high zirconia (16% minimum), alkali-resistant glass fiber. Optimum glass fiber content of 5% by weight. Lower fiber content results in lower early ultimate strengths, higher fiber content can produce composite compaction and consolidation difficulties.
ultimate test
แปลว่าการทดสอบโดยใช้คลื่นความถี่สูง, การทดสอบอุลตราโซนิก
