ตัวกรองผลการค้นหา
Bending Strength
แปลว่า(english) Upper limit of normal stress of a beam at which fracture or excessive plastic deformation occurs.
Consistency
แปลว่า(Concrete Engineering) The degree of plasticity of fresh concrete or mortar The normal measure of consistency is slump for concrete and flow for mortar.
Kinetic Energy:
แปลว่า(english) The energy of a moving mass; equal to (mv^2)2. Where m is mass and v is the magnitude of the velocity.
เกลือปรกติ
หมายถึง(เคมี) น. เกลือที่เกิดขึ้นโดยธาตุไฮโดรเจนชนิดที่แปรสภาพเป็นไอออนได้ ซึ่งมีอยู่ในโมเลกุลของกรดถูกโลหะหรือหมู่ธาตุที่เทียบเท่าโลหะเข้ามาแทนที่จนหมดสิ้น เช่น โซเดียมซัลเฟต (Na2SO4). (อ. normal salt).
Fluidization
แปลว่า(Environmental Engineering) The suspension of particles by sufficient upward velocity of the fluid. During fluidization the gravity force is overcome by a combination of buoyancy and fluid friction.
Stress:
แปลว่า(english) The intensity of internal force acting at a point in an object. Stress is measured in units of force per area. See shear stress and normal stress.
Bamboo Grain Structure
แปลว่า(english) A structure in wire or sheet in which the boundaries of the grains tend to be aligned normal to the long axis and to extend completely through the thickness.
Blast Cleaning (blasting)
แปลว่า(english) A process for cleaning or finishing metal objects by use of an air jet or centrifugal wheel that propels abrasive particles (grit, sand, or shot) against the surfaces of the workpiece at high velocity.
Colloids
แปลว่า(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.
Backwardation
แปลว่า(english) Market condition where the spot, or current price for a metal is higher than the three-month delivery price. This usually indicates immediate demand is perceived to be stronger than long-term demand. Not considered to be a "normal" market state (See Contango).
Blow Back
แปลว่า(english) A coating defect consisting of a lower coating film weight on the bottom of the coated sheet caused by high velocity air in the oven. Blow back usually occurs with high solids coatings which have little solvent to evaporate and "set" the film.
Age Hardening
แปลว่า(english) Hardening by aging, usually after rapid cooling or cold working. The term as applied to soft, or low carbon steels, relates to a wide variety of commercially important, slow, gradual changes that take place in properties of steels after the final treatment. These changes, which bring about a condition of increased hardness, elastic limit, and tensile strength with a consequent loss in ductility, occur during the period in which the steel is at normal temperatures.
