B-scan (ut)
| Глоссарий терминов по технологиям неразрушающего контроля (NDT) |
A data presentation method generally, applied to pulse echo techniques which yields a two dimensional view of a cross-sectional plane through the test piece. the horizontal sweep is proportional to the test piece, with the vertical sweep proportional to distance, showing the front and back surfaces and discontinuities between.

- The method used to show ultrasonic wave information. may include a, b, or c scans displayed either on various types of recorders or cathode ray instrumentations.
- Technique used to show ultrasonic information. this may include a-scans, b-scans or c-scans, displayed on various types of recorders or display instruments.7,21 primary reference response level: ultrasonic response from the basic reference reflector at the specified sound path distance, electronically adjusted to a specified percentage of full screen height.7
Dimensional, английский
Размерный; пространственный; имеющий измерение 3-dimensional configuration трехмерная организация 2.5-dimensional configuration 2,5-мерная организация 2-dimensional configuration двухмерная организация
Horizontal, английский
- Горизонталь; горизонтальный
- Горизонталь; горизонтальный 287
- At right angles to the direction of gravity; on the level; parallel to the horizon; neither vertical nor inclined.
- A direction parallel to the horizon, or what is commonly termed lying flat. one of the greatest inconveniences navigators have to struggle with is the frequent want of a distinct sight of the horizon. to obviate this a horizontal spinning speculum was adopted by mr. lerson, who was lost in the victory man-of-war, in which ship he was sent out to make trial of his instrument. this was afterwards improved by smeaton, and consists of a well-polished metal speculum about 3-1/2 inches in diameter, inclosed within a circular rim of brass, so fitted that the centre of gravity of the whole shall fall near the point on which it spins. this is the end of a steel axis running through the centre of the speculum, above which it finishes in a square for the convenience of fitting a
Proportional, английский
- Член пропорции
- A пропорциональный analogy
- Пропорциональный

Extrusion defect, английский
A defect of flow in extruded products caused by the oxidized outer surface of the billet flowing into the center of the extrusion. it normally occurs in the last 10 to 20% of the extruded bar. also called “pipe” or “core.”
C-scan (ut), английский
A data presentation method generally applied to pulse echo techniques yielding a two dimensional plan view of the scanned surfaces of the part. through gating, only echoes arising from the interior of the test object are indicated. in the c-scan no indication is given of the echo depth.
