X-ray
| Авиационный алфавит |
- 1. a ray with a very short wavelength, which is invisible, but can go through soft tissue and register as a photograph on a film. x-rays are used in diagnosis in radiography, and in treating disease by radiotherapy. the x-ray examination showed the presence of a tumour in the colon. 2. a photograph taken using x-rays the dentist took some x-rays of the patient’s teeth. he pinned the x-rays to the light screen. 3. an examination in which x-ray photographs are taken all the staff had to have chest x-rays. verb to take an x-ray photograph of a patient there are six patients waiting to be x-rayed. comment: because x-rays go through soft tissue, it is sometimes necessary to make inter- x-ray imaging 458 nal organs opaque so that they will show up on the film. in the case of stomach x-rays, people take a barium meal before being photographed (contrast radiography); in other cases, such as kidney x-rays, radioactive substances are injected into the bloodstream or into the organ itself. x-rays are used not only in radiography for diagnosis but as a treatment in radiotherapy as rapidly dividing cells such as cancer cells are most affected. excessive exposure to x-rays, either as a person being treated, or as a radiographer, can cause radiation sickness.

Рентгеновские лучи, русский
, не видимое глазом электромагнитное излучение с длиной волны 10-5 - 102 нм. проникают через некоторые непрозрачные для видимого света материалы. испускаются при торможении быстрых электронов в веществе (непрерывный спектр) и при переходах электронов с внешних электронных оболочек атома на внутренние (линейчатый спектр). источники - рентгеновская трубка, некоторые радиоактивные изотопы, ускорители и накопители электронов (синхротронное излучение). приемники - фотопленка, люминесцентные экраны, детекторы ядерных излучений. рентгеновские лучи применяют в рентгеновском структурном анализе, медицине, дефектоскопии, рентгеновском спектральном анализе. открыты в 1895 в. рентгеном.

Wavelength, английский
- Light is made up of electromagnetic waves; wavelength is the crest (peak)-to-crest distance between two adjacent waves.
- Для оптических сетевых устройств длина волны светового потока составляет 850, 1300, 1310 и 1550 нм
- The optical term for frequency. fiber optics generally uses the 850 nm, 1300/1310 nm, 1550 nm and 1625 nm wavelengths for transmission purpose due to the marriage of performance with light sources, optical fibers, and optical detector technologies
- Distance in the direction of propagation of a periodic wave between two successive points at which the phase is the same. tel 203•377•8282 fax 203•378•2457 e-mail res_sales@oriel.com url www.oriel.com 9-17 polarization lenses optics prisms & filters beam splitters windows, substrates & mirrors properties of optical coatings optical materials
- The length of the light wave, usually measured from crest to crest, which determines its color. common units of measurement are the micrometer (micron), the nanometer, and the angstrom unit.
- The spatial period of a plane wave
- The distance between "waves" in the electromagnetic field, specified as angstroms or nanometers.
- The distance an electromagnetic wave travels in the time it takes to oscillate through a complete cycle. wavelengths of light are measured in nanometers (10-9 m) or micrometers (10-6m).
- The linear distance occupied by one complete cycle of vibration of an energy form from any given point to the next point characterized by the same phase.
- For light waves or sound waves, the distance between two successive points of a periodic wave in the direction of propagation, in which the oscillation has the same phase; the distance the wave travels in one period. for light waves three common units of wavelength are: micrometer, nanometer, and angstrom. wave molding, oundy molding, swelled chamfer, undulating molding, undy
- Длина волны wax 1. воск 2. парафин 3. пластичная глина way 1. путь; дорога 2. проход; переход 3. колея 4. направление, сторона 5. амер, расстояние
- The physical length between corresponding points of successive cycles of a wave. low frequencies have long wavelengths; high frequencies have short wavelengths.
- The distance between the crests of a wave in a radio signal, measured as the speed of light divided by the frequency in- hz.
- The distance between one peak of a wave and the next peak
- Light is measured by its wavelength (in nanometers) or frequency (in hertz). one wavelength. equals the distance between two successive wave crests.
- The distance between two points having the same phase in two consecutive cycles of a periodic wave, along a line in the direction of propagation.
- Distance between repeating values of a wave — for example, the distance from one peak to the next peak on a sine wave. wavelength is a fundamental descriptor when discussing wave behavior, system sensitivity, and diffraction effects.
- Distance between repeating values of a wave. for example, the distance from one peak to the next peak on a sine wave.
- Distance between repeating values of a wave. for example, the distance from one peak to the next peak on a sine wave. wavelength is generally measured in nanometers when considering uv-a radiation (for example, 365 nm). compare frequency.
- Distance between repeating units of a wave. for example, the distance from one peak to the next peak.
- Distance needed in the propagation direction for a wave to go through a complete cycle.7,21
Photograph, английский
- A picture taken with a camera, which uses the chemical action of light on sensitive film verb to take a picture of something with a camera
- Фотография, фотоснимок
Radiography, английский
- Radiografía
- The work of examining the internal parts of the body by taking x-ray photographs
- See radiologic testing. radiologic testing (rt): use of penetrating radiant energy in the form of x-rays, gamma rays, or neutrons for nondestructive testing of objects to provide images of the objects’ interiors. also called radiography; radiographic testing.
Radiotherapy, английский
The treatment of diseases by exposing the affected part to radioactive rays such as x-rays or gamma rays comment: many forms of cancer can be treated by directing radiation at the diseased part of the body.
Examination, английский
- Обследование
- Экспертиза; проверка; рассмотрение (оценка патентоспособности заявки на патент, производимая патентным ведомством)
- 1. an act of looking at someone or something carefully from the examination of the x-ray photographs, it seems that the tumour has not spread. 2. the act of looking at someone to find out what is wrong with him or her the surgeon carried out a medical examination before operating. 3. a written or oral test to see if a student is progressing satisfactorily (note: in this sense, often abbreviated to exam.)
- An examination of a dead body by a pathologist to find out the cause of death the post mortem showed that he had been poisoned. abbr pm. also called autopsy
- A searching by, or cognizance of, a magistrate, or other authorized officer. now strict in navy and army.
- Проверка; исследование; рассмотрение
- The checking of a taxpayer`s tax return, accounts, self-assessment calculations, etc. the process may or may not include an audit of the taxpayer`s own books.
- Осмотр; освидетельствование, обследование; исследование, проверка, контроль
- Изучение
- The study of a patent application by a patent office examiner to determine whether or not an invention can be patented and whether the application complies with all the legal requirements (including formal requirements). depending on issues raised in the resulting examination report, amendment of the patent application may be required.
- Process of testing materials, interpreting and evaluating test indications to determine if the test object meets specified acceptance criteria.1
