Неоднородность
| Англо-русский словарь по геологии |
(1) различный состав между центром и поверхностью единицы микроструктуры (типа дендрита, зерна, карбидной частицы) как следствие неравномерного затвердевания, в результате перепада температур. (2) центральная полость в торце выдавливаемого стержня.

Heterogeneity, английский
- Гетерогенность
- Неоднородность; гетерогенность
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.

Coring, английский
- Croma coring
- Removing a core from a concrete structure or rock foundation, for test purposes.
- This operation collects geological samples from the formation. a special coring bit is used to drill out a cylindrical core sample inside the drill bit and the coring tool assembly.
- The process of cutting a vertical, cylindrical sample of the formations encountered as an oil well is drilled. the purpose of coring is to obtain rock samples, or cores, in such a manner that the rock retains the same properties that it had before it was removed from the formation. cretaceous :of or relating to the geologic period from about 135 million to 65 million years ago at the end of the rsmyth.shr.glossary.doc mesozoic era, or to the rocks formed during this period, including the extensive chalk deposits for which it was named.
