primary surface
1primary surface — A rectangular surface longitudinally centered about a runway. Its width is a variable dimension, and it usually extends 200 ft (60 m) beyond each end of the runway when the runway has a specially prepared hard surface. When the runway has no… …
2Primary Surface — I Primary Surface [dt. »primäre Oberfläche«] die, Teil der Bilddaten in einem Bildschirmspeicher, der zum sichtbaren Bildbereich gehört (im Unterschied zu den nicht sichtbaren, den Offscreen Surfaces, dt. »Oberflächen außerhalb des… …
3Surface plate — A surface plate is a solid, flat plate used as the main horizontal reference plane for precision inspection, marking out (layout), and tooling setup. The surface plate is often used as the baseline for all measurements to the workpiece, therefore …
4Primary form — is used in surface metrology to refer to the over all shape of a surface which can be measured quantitatively, as contrasted with more local or higher spatial frequency variations in the surface dimensions such as surface waviness or surface… …
5Surface Marker Buoy — (standard) = A Surface Marker Buoy, SMB or simply a blob is an inflatable buoy used by SCUBA divers, with a line, to mark the diver s position to their surface, safety boat while the diver is underwater.SMBs are inflated on the surface before… …
6Primary color — Primary colors are sets of colors that can be combined to make a useful range (gamut) of colors. For human applications, three are often used; for additive combination of colors, as in overlapping projected lights or in CRT displays, the primary… …
7Surface enhanced Raman spectroscopy — Surface Enhanced Raman Spectroscopy, or Surface Enhanced Raman Scattering, often abbreviated SERS, is a surface sensitive technique that results in the enhancement of Raman scattering by molecules adsorbed on rough metal surfaces. The enhancement …
8Primary immunodeficiency — Primary immunodeficiencies are disorders in which part of the body s immune system is missing or does not function properly. To be considered a primary immunodeficiency, the cause of the immune deficiency must not be secondary in nature (i.e.,… …
9Surface metrology — is the measuring of small scale features on surfaces, and is a branch of Metrology. Surface primary form, surface waviness and surface roughness are the parameters most commonly associated with the field. It is important to many disciplines and… …
10Surface exposure dating — is a collection of geochronological techniques for estimating the length of time that a rock has been exposed at or near Earth s surface. Surface exposure dating is used to date glacial advances and retreats, erosion history, lava flows,… …
