- A spurious image resulting from an echo.
- Global horizontal sounding technique
- To sail slowly when there is apparently no wind.
- An otdr signature caused by an optical echo that occurs when light reflects off two reflective surfaces, creating a false image at double the distance from the initial event
- A false image in the lens of an instrument.
- [1] to sail slowly when there is no perceptible wind. [2] a secondary, duplicate, or false image on a radar screen due to echoes or interference. also phantom.

Ghost ball, английский
Imaginary aiming target where the cue ball needs to impact the object ball so the line through their centers (the impact line) is in the direction of the desired object ball path.

Ghost image, английский
- In spectacle optics, an unwanted secondary image formed by internal reflections from the rear or by reflection from the anterior surface of the cornea and a second reflection from the ocular (eye) surface of a spectacle lens.

Ghost ships, английский
There are several types of maritime apparition. some are thought to warn of coming disaster while others recall earlier tragedies. the block island phantom does both. some, such as the cursed corsair, the flying dutchman, and the japanese yureisen, are sinister specters that appear out of nowhere. others were mystery ships like mary celeste, discovered intact with crew mysteriously vanished. and some appear to be explicable phenomena such as the chaleur bay phantom and jenny the glacial ghost. interestingly, some 90 percent of all phantom ship sightings are between the fortieth and fiftieth latitudes.
Ghost site, английский
A web site that remains live but is no longer updated or maintained or only done so very infrequently.
Ghost suppression, английский

Indication, английский
- Индикация
- A situation or sign which suggests that a specific treatment should be given or that a condition has a particular cause sulpha drugs have been replaced by antibiotics in many indications. contraindication
- (1) notice given by a dealer (through autex) or customer of an interest in buying or selling stock, sometimes including specific volume and price; (2) approximation of where a specialist sees buy and sell interest to tighten the range to an opening price.
- Выражение интереса (бирж.)
- In nondestructive inspection, a response or evidence of a response, that requires interpretation to determine its significance.
- Nondestructive test response that requires interpretation to determine its relevance. these include such things as meter deflections, shadows on radiographs, blips on screens, or localized discolorations on surfaces. see also defect; discontinuity; indication, false; indication, nonrelevant. indication, discontinuity: visible evidence of a material discontinuity. subsequent interpretation is required to determine the significance of an indication. indication, false: test indication that could be interpreted as originating from a discontinuity where no discontinuity exists. compare defect; ghost; indication, nonrelevant. false indications are an economic liability for inspection because they must be investigated. indication, nonrelevant: indication due to misapplied or improper testing. may also be an indication caused by an actual discontinuity that does not affect the usability of the test object (a change of section, for instance). indication, relevant: indication from a discontinuity (as opposed to a nonrelevant indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size, shape, orientation, or location.
- Nondestructive test response that requires interpretation to determine its relevance.4 see also defect; discontinuity; false indication; nonrelevant indication. indication, nonrelevant: indication that has no relation to a discontinuity that might constitute a defect.1 test response caused by geometry or by a physical condition that is not a discontinuity. indication, relevant: indication from a discontinuity (as opposed to a false indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size or location.1
- Nondestructive test response that requires interpretation to determine its relevance. compare defect; discontinuity; indication, false; indication, nonrelevant. indication, false: (1) test indication that could be interpreted as originating from a discontinuity but that actually originates where no discontinuity exists in the test object. (2) indication due to misapplied or improper testing. compare indication, nonrelevant; defect. indication, nonrelevant: indication that has no relation to a discontinuity that might constitute a defect. test response caused by geometry or by a physical condition that is not a discontinuity (a change of section, for instance). indication, relevant: indication from a discontinuity (as opposed to a false indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size or location.

- Nondestructive test equipment response to a discontinuity that requires interpretation to determine its relevance.4 in magnetic particle testing, a visible accumulation of magnetic particles that serves as evidence of a magnetic leakage field.
- Defect, discontinuity, false indication and nonrelevant indication. induced current magnetization: noncontact means for testing delicate ring shaped objects for circumferential discontinuities. the technique is based on the fact that a time varying current passing through an internal conductor, often a soft iron or laminated core, self-induces an encircling magnetic field. this time varying magnetic field will induce a secondary current circling through the ring. this secondary current then self-induces the toroidal magnetic field used for testing.
- Nondestructive test equipment response to a reflector, requiring interpretation to determine its relevance. compare crack; defect; discontinuity; indication, false.10 indication, discontinuity: visible evidence of a material discontinuity. subsequent interpretation is required to determine the indication’s significance.10 indication, false: test indication that originates where no discontinuity exists in the test object. compare defect; indication, nonrelevant.10 indication, nonrelevant: indication possibly caused by an actual discontinuity that does not affect the usability of the test object (a change of section, for instance) or that is smaller than a relevant indication. compare indication, false and indication, relevant.10 indication, relevant: indication from a discontinuity (as opposed to a nonrelevant indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size, shape, orientation or location. compare indication, nonrelevant.10,19

Radiation maze (rt), английский
An indirect route of access to a room that contains a radiation source. it is designed to allow easy access when the source is turned off or is fully shielded, and to reduce radiation intensity outside the room to acceptable levels when the source is turned on or exposed. reduction of radiation intensity is achieved through multiple scattering from walls and application of the inverse square law.
Reflection (ut), английский
An indication that has arisen as a result of an incident sound beam being reflected at the boundary of two materials of dissimilar acoustic impedance.
