Metallograph
| Глоссарий горнодобывающей промышленности |
- An optical instrument designed for both visual observation and photomicrography of prepared surfaces of opaque materials at magnifications ranging from about 25 to about 1500 diameters.
- Short term for metallographic microscope.

Металлографический микроскоп, русский
Оптический прибор, разработанный для визуального наблюдения и получения микрофотографий подготовленных поверхностей непрозрачных материалов при увеличениях от ×25 до ×2000. прибор состоит из высокоинтенсивного освещающего источника, микроскопа и фотокамеры. на некоторых приборах, специально приспособленных для исследования поверхностей образца, обеспечено использование поляризованного света, наклонного освещения, темнополевого освещения и яркополевого освещения.

Instrument, английский
- A term used to describe a sensor (or sensors), the associated transducer(s), and the data read-out or recording device.
- (измерительный) прибор
- One of many terms for a light, heard mostly in the theater. see: lights.
- A piece of equipment or a tool the doctor had a box of surgical instruments.
- A term of extensive application among tools and weapons; but it is here introduced as an official conveyance of some right, or the record of some fact.
- A legal document that records an act or agreement and provides the evidence of that act or agreement. instruments include contracts, notes, and leases (e.g. a debt instrument).

- Прибор, инструмент
- To tag the source code in order to measure the amount of time spent in each area.

Observation, английский
- Наблюдение; измерение
- Наблюдение; измерение оцт object задача; цель
- Observación
- The process of watching and examining a person or thing over a period of time she was admitted to hospital for observation.
- N наблюдение
- Наблюдение
- In nautical astronomy, denotes the taking the sun, moon, or stars` altitude with a quadrant or sextant, in order thereby to find the latitude or time; also, the lunar distances.
- [1] general; the act of measuring some magnitude with an instrument, such as the time of an occultation (with a clock); the right ascension of a star (with a transit instrument and clock); the sun’s altitude, or the distance of the moon from a star (with a sextant); the temperature (with a thermometer); etc. [2] nautical; a celestial sighting, taken in order to calculate a time or position. [3] the information so acquired.
Photomicrography, английский
Metallographic, английский
Microscope, английский
- Microscopio
- A scientific instrument with lenses, which makes very small objects appear larger the tissue was examined under the microscope. under the microscope it was possible to see the cancer cells. comment: in an ordinary or light microscope the image is magnified by lenses. in an electron microscope the lenses are electromagnets and a beam of electrons is used instead of light, thereby achieving much greater magnifications.
- Device used to form a highly magnified image of tiny objects for clear visualization
- Instrument that provides enlarged images of small objects. microscope, compound: conventional microscope, using geometrical optics for magnification. also called laboratory microscope. microscope, interference: magnifier using the wavelength of light as a unit of measure for surface contour and other characteristics. microscope, metallographic: metallurgical microscope incorporating a camera. also called a metallograph. most metallographic microscopes share these features: (a) stand with concealed shock absorbers, (b) intense light source, (c) inverted stand so that the test object is face down, (d) viewing screens for prolonged tasks such as dirt count or grain size measurements, (e) bright, dark and polarized illumination options. microscope, metallurgical: microscope designed with features suited for metallography. microscope, phase contrast: laboratory microscope with two additional optical elements to transmit both diffracted and undiffracted light, revealing refractive index discontinuities in a completely transparent test object. microscope, polarizing: microscope with polarizing elements to restrict light vibration to a single plane for studying material with directional optical properties. as fibers, crystals, sheet plastic and materials under strain are rotated between crossed polarizers on the microscope stage, they change color and intensity in a way that is related to their directional properties. mig welding: see gas metal arc welding.
- Instrument that provides enlarged images of very small objects.
