- A series of square waves or other beam deflections displayed on the cathode-ray tube screen of the ultrasonic equipment is used to determine the distance from the test surface of the article being inspected to a subsequent discontinuity or boundary.
- Series of indications on the horizontal trace of the display screen to show increments of time or distance.7,21

Discontinuity, английский
- Разрывность (течения, кривой)
- Разрыв (непрерывности); нарушение сплошности; перегиб кривой; разрезность {конструкции) о ~
- [stratigraphy] any interruption in sedimentation, whatever its cause or length, usually a manifestation of nondeposition and accompanying erosion; an unconformity. gg part 629 - glossary 629-24 (430-vi-nssh, 2008)
- An interruption in the normal physical structure or configuration of a part such as cracks, laps, seams, inclusions, porosity. a discontinuity may or may not affect the usefulness of a part. see defect.
- Interruption in the physical structure or configuration of a test object. after nondestructive testing, a discontinuity indication may be interpreted to be a defect. compare defect; indication. discontinuity, artificial: reference discontinuity such as hole, indentation, crack, groove, or notch introduced into a reference standard to provide accurately reproducible indications for determining test sensitivity levels.
- Interruption in the physical structure or configuration of a test object. after nondestructive testing, a discontinuity indication can be interpreted to be a defect.4,7 compare defect; indication. discontinuity, artificial: reference discontinuity such as hole, indentation, crack, groove or notch introduced into a reference standard to provide accurately reproducible indications for determining test sensitivity levels.4 discontinuity, inherent: material anomaly originating from solidification of cast metal. pipe and nonmetallic inclusions are the most common inherent discontinuity and can lead to other types of discontinuities in fabrication.2,5 discontinuity, primary processing: discontinuity produced from the hot or cold working of an ingot into forgings, rods, bars and other shapes.2,5 discontinuity, secondary processing: discontinuity produced during machining, grinding, heat treating, plating or other finishing operations.2,5 discontinuity, service induced: discontinuity caused by the intended use of the part.
- Intentional or unintentional interruption in the physical structure or configuration of a part.1,4 after nondestructive testing, unintentional discontinuities interpreted as detrimental in the host object may be called flaws or defects. compare defect, dislocation and indication.1 discontinuity, artificial: reference discontinuities such as holes, indentations, cracks, grooves or notches that are introduced into a reference standard to provide accurately reproducible indications for determining sensitivity levels.1 discontinuity, primary processing: in metals processing, a material anomaly produced from the hot or cold working of an ingot into forgings, rod and bar.1 discontinuity, service induced: material anomaly caused by the intended use of the part.1 display resolution, thermal: precision with which an instrument displays its assigned measurement parameter (temperature), usually expressed in degrees, tenths of degrees, hundredths of degrees and so forth.3
- Interruption in the physical structure or configuration of a test object. after nondestructive testing, a discontinuity indication may be interpreted as a defect. compare anomaly; defect; indication. drift (electronic): change in output reading of an instrument, usually due to temperature change.
- Interruption in the physical structure or configuration of a test object. after nondestructive testing, a discontinuity indication may be interpreted as a defect. compare anomaly; defect; indication. discontinuity, artificial: reference anomaly such as hole, indentation, crack, groove, or notch introduced into a reference standard to provide accurately reproducible indications for determining test sensitivity levels. see also known discontinuity standard. discontinuity, inherent: material anomaly originating from solidification of metal. pipe, banding, and nonmetallic inclusions are the most common inherent discontinuities and can lead to other types of discontinuities in fabrication. discontinuity, primary processing: discontinuity produced from the hot or cold working of an ingot into forgings, rods, bars, and other shapes. glossary d-e 497 discontinuity, secondary processing: discontinuity produced during machining, grinding, heat treating, plating, or other finishing operations. discontinuity, service induced: discontinuity caused by the intended use of the part. see also brittle crack propagation; creep; ductile crack propagation; fatigue crack propagation.
- Interruption in the physical structure or configuration of a test object. after nondestructive testing, a discontinuity indication can be interpreted to be a flaw or a defect.10 compare defect; indication.5,6 discontinuity, artificial: reference discontinuity such as hole, indentation, crack, groove, or notch introduced into a reference standard to provide accurately reproducible indications for determining sensitivity levels.4
- Interruption in the physical structure or configuration of a test object. after nondestructive testing, a discontinuity indication can be interpreted to be a flaw or a defect.10 compare defect; indication.

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
