Hardness, английский
- Dureté
- A property of wood that enables it to resist indentation. it is measure in kn and is often determined by the janka hardness test.
- The resistance of a substance to surface abrasion.
- Твердость
- A property of wood that enables it to resist indentation.
- A diamond’s ability to resist scratches
- Generally measured using the mohs scale. resistance a material offers to scratching or abrasion.
- As used by individuals associated with the drilling and bit-setting industry, the relative ability of a mineral to scratch another mineral or to be penetrated by a knoop indenter; also, the relative ability of a metal to resist being penetrated by the indenter point of a vickers, brinnell, or eockwell hardness-testing apparatus.
- Твёрдость; жёсткость; стойкость ~ of water жёсткость воды
- 1. when used in reference to water, hardness is the total parts per million (ppm) of calcium an caco3 plus the magnesium expressed as equivalent caco3 [ppm hardness (as caco3) = (ppm ca x 2.497 + ppm mg x 4.116)]. 2. used in reference to pulp to denote the degree of delignification.
- Resistance of a material to indentation or scratching
- A measure of the ability of a material to withstand penetration by a hard pointed object. regarding thermal interface materials, this property is usually inversely proportional to the ability of a material to conform to uneven surfaces. hardness shore a (shore d, shore )
- Resistance of metal to plastic deformation, usually by indentation. however, the term may also refer to stiffness or temper or to resistance to scratching, abrasion, or cutting.
- In materials science, the resistance of a material to deformation, scratching, abrasion, or cutting. see also brinell hardness; rockwell hardness.
- Resistance of metal to denting, to plastic deformation by bending or to mechanical deformation by scratching, abrasion or cutting. typically measured by indentation.

Hardness testing, английский
By means of instruments such as brinnel, rockwell, scleroscope, vickers, etc.
Hardness wheel, английский
Rockwell, английский
A unit of hardness as determined by a rockwell hardness tester. see rockwell hardness. compare knoop hardness.
Rockwell hardness number, английский
Твердость `по роквеллу
Rockwell hardness test, английский
A test for determining the hardness of a material based upon the depth of penetration of a specified penetrator into the specimen under certain arbitrarily fixed conditions of test.
Resistance, английский
- Property of a conductor that opposed the current flow produced by a given difference of potential. the ohm is the practical unit of resistance.
- Уровень сопротивления - уровень цен, при котором активные продажи могут приостановить или развернуть тенденцию к повышению;
- Сопротивление (параметр)
- Сопротивление
- Сопротивление, т. е. уровень цен, при котором активные продажи могут приостановить или развернуть тенденцию к повышению.
- 1. the ability of a person not to get a disease 2. the ability of bacteria or a virus to remain unaffected by a drug the bacteria have developed a resistance to certain antibiotics. 3. opposition to a force
- Resistencia
- Устойчивость; резистентность resource for child health (reach)
- Устойчивость; резистентность
- The property of opposing movement, for example [1] electrical conductors offer resistance to the flow of electricity and dissipate some of its energy, usually as heat. [2] water resists the movement of vessels or other objects by parasitic drag, consuming some of the power available to drive the vessel forward.
- Imperviousness of the coating to mechanical, chemical, physical or weather influences
- Capacity of a member or component, or a cross-section of a member or component of a structure, to withstand actions without mechanical failure e.g. bending resistance, buckling resistance, tension resistance
- A material’s ability to restrict the flow of electrical current through itself. measured in ohms.
- The opposition of a circuit to the flow of current . resistance is measured in ohms, and can be calculated by dividing the voltage by current.
- The ability to impede (resist) the flow of electric current. with the exception of superconductors, all substances have a greater or lesser degree of resistance. substances with very low resistance, such as metals, conduct electricity well and are called conductors. substances with very high resistance, such as glass and rubber, conduct electricity poorly and are called nonconductors or insulators.
- An effective upper bound on prices achieved because of many willing sellers at that price level.
- Capacity of a component, or cross section of a component of a structure to
- The opposition to the flow of an electrical current through a conductor or circuit that does not include inductive or capacitive elements. it can be expressed as the ratio of the applied voltage to the current.
- Resistance is the opposition to the flow of an electrical current through a conductor. its unit is the ohm.
Indentation, английский
- Сдвиг; введение отступов; структурированное расположение текста; структурирование текста
- Displacement of the left or right edge of a block of text in relation to the margin or to other blocks of text.
- In a spot, seam or projection weld, the depression on the exterior surface of the base metal.
