Etch angle
| Diamond Glossary (алмазы и бриллианты - глоссарий терминологии) |
The angle formed between the true horizon and the actual plane of the etch ring in an acid bottle as measured before capillarity corrections are applied. also called apparent angle. compare apparent dip.

Angle, английский
- Угол
- The space or aperture intersected by the natural inclination of two lines or planes meeting each other, the place of intersection being called the vertex or angular point, and the lines legs. angles are distinguished by the number of degrees they subtend, to 360°, or the whole circumference of a circle. angles are acute, obtuse, right, curvilinear, rectilinear, &c. (all of which see).

Angle beam, английский
- Ultrasound beam traveling at an acute angle into a medium. the angle of incidence or angle of refraction is measured from the normal to the entry surface.
- Ультразвуковой луч, проникающий в среду под острым углом. угол падения или угол преломления измеряется от нормали к входной поверхности.
- In ultrasonic testing, ultrasound beam traveling at an acute angle into a medium. the angle of incidence or angle of refraction is measured from the normal to the entry surface.15

Angle beam (ut), английский
A sound beam traveling at some angle other than normal to me surface of the test object. measured from normal incidence.
Angle beam test technique, английский
In ultrasonic testing, inspection technique in which transmission of ultrasound is at an acute angle to the entry surface.18
Angle beam testing, английский
- Technique of ultrasonic testing in which transmission of ultrasound is at an acute angle to the entry surface.
- Метод ультразвукового контроля, при котором передача ультразвука происходит под острым углом к входной поверхности.
- Technique of ultrasonic testing in which transmission of ultrasound is at an acute angle to the entry surface.7,21
Angle beam transducer, английский
- Transducer that transmits or receives ultrasonic energy at an acute angle to the surface. this may be done to achieve special effects such as setting up transverse or surface waves by mode conversion at an interface.
- Преобразователь, который передает или принимает ультразвуковую энергию под острым углом к поверхности. это можно сделать для достижения специальных эффектов, таких как создание поперечных или поверхностных волн путем преобразования мод на интерфейсе.

Angle blasting, английский
Sandblasting, or the like, at an angle of less than 90°. angle block, glue block a small block of wood, triangular in cross section, which is used to stiffen two intersecting pieces of wood at right angles; for example, under the step of a stair.
Angle board, английский
A board whose surface is cut at a desired angle; serves as a guide for cutting and/or planing other boards at the same angle. ancon, 1
Angle bond, английский
A tie used to bond masonry work at wall corners. angle brace 1. a strip of material which is fixed across a frame to make it rigid, as a wood strip which is nailed temporarily across the corners of a window frame or doorframe to maintain squareness during shipment or in handling before permanent installation; also called an angle tie. 2. an angle iron. 3. a special brace which is used for drilling where there is insufficient room for an ordinary brace handle to turn.
Angle brace, английский
Angle brace, 1., английский
Angle brace, 3. corner block 1., английский
Angle bracket, английский

Angle brick, английский
Any brick having an oblique shape to fit an oblique, salient corner.
Angle buttress, английский
One of two buttresses at right angles to each other, forming the corner of a structure.
Capillarity, английский
- A property of a solid-liquid system manifested by the tendency of the liquid in contact with the solid to rise above or fall below the level of the surrounding liquid; this phenomenon is seen in a smallbore (capillary) tube.
- A phenomenon observable when making borehole-inclination surveys by the acid-etch method, wherein the upper surface of the dilute hydrofluoric acid is seen to curve upward, forming a concave surface. when the acid bottle is in a true vertical or horizontal position, the concave surface is symmetrical, and the resultant etch plane is horizontal. when the acid bottle is tilted, the concave surface is asymmetric in shape; the resultant etch plane is not horizontal, and the angle so indicated is always greater than the true inclination of the borehole. see apparent angle, capillarity correction.
- The peculiar action by which the upper surface of a liquid, in contact with a solid, such as the inside walls of a glass tube, is curved upward when the containing walls are wetted by the liquid and downward when not wetted. see meniscus.
- Капиллярность 99 capital
Corrections, английский
- Reductions of observations of the sun, moon, or stars.
- A set of features that enables users to improve the quality of their images with just one or two clicks. galleries help the user optimize characteristics such as brightness, contrast, color, and sharpness.

Cone angle, английский
- The angle included between the opposite sides of the cone in a concave bit, measured in degrees.
- The angle between the edges of the spot light’s beam. if you shine a flashlight on the ground, you will notice that it does not light the ground evenly, but that the light gets dimmer the farther from the center it gets. the cone angle determines how quickly this falloff happens.
True dip, английский
The angle at which veins, strata, etc., dip, as measured vertically downward from the horizon along a line at right angles to the strike of the veins, strata, etc.; also, the dip of a vein, strata, etc., as determined on oriented core. see core orienta¬tion, oriented core. compare apparent dip.
