Reflect, английский
- A gradient brush option that makes the gradient repeat in alternating reflections.
- To copy driver binaries, install services, and add registry keys for one or more drivers from a driver package onto a system, without the context of a specific device. a system can be booted from reflected drivers, however full device installation may still be required in order to enable full driver functionality.
Reflect prevention sheet, английский
Reflectance, английский
- The percentage of light that is reflected from an object. spectrophotometers measure an object's reflectance at various intervals along the visible spectrum to determine the object color's spectral curve. see spectral curve, spectral data.
- The ratio of light returned from a surface expressed as a percentage.
- Отражательная способность
- The percentage of light reflected from a component, such as a connector, splice, splitter, or wdm
- The ratio of the reflected flux to the flux incident on a surface. reflectance coefficient, reflectance factor
- Коэффициент отражения, отражательная способность
- Ratio of reflected wave energy to incident wave energy. also known as reflectivity.
Reflectance (or reflection factor), английский
Отражательная способность (или коэффициент отражения). отношение потока лучистой энергии (или света), отражаемой данной поверхностью, к потоку лучистой энергии (или света), падающему на эту поверхность.
Reflectance pattern, английский
A reflectance pattern is an observation whose attributes have been normalized so that their values add up to one. see also: ann, normalization.
Reflectance reflectivity, английский
The ratio of the reflected radiant power to the incident radiant power.
Reflectance. light-reflective glass, английский
Reflectancia, испанский
Reflectancia ., испанский
Reflectancia del nivel de base ., испанский
Reflected, английский
Reflected glare, английский
- Relatively bright light that does not enter the eye directly from the light source, but after it has been deflected by a surface which the direct light has illuminated. it can be either diffuse or specular.
- Glare resulting from specular reflection of high brightness in polished or glossy surfaces in the field of view. also
Reflected light, английский
- Scene illumination multiplied by reflectance. this is the amount of light returned to the camera and determines the quality of picture.
- Various surfaces in a scene reflect between 1% and 95% of the incident light. specular surfaces will reflect it narrowly. diffuse (rough, irregular, or matte) surfaces scatter it. also see: glare and bounce light for further reflections.
Reflected light meter, английский
A meter that reads light reflected from the subject. all in-camera meters are of this type.
Reflected light meter (rlm), английский
An rlm reads light that is reflected from a scene. aim these meters at the subject or scene or a gray card from the direction of the camera. also see: spot meter and 18% assumption*.
Reflected plan, английский
A plan, viewed from above, laid out as if it were projected downward on an upper surface (such as a ceiling); thus a member seen on the left from below appears to the right on the plan.
Reflected sound, английский
Those sound waves that reach the listener or audience after being reflected from one or more surfaces (walls, ceilings, floors, etc.)
Reflected wave, английский
Reflected-light microscope, английский
Reflected-light microscopy, 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

Ghost (ut), английский
An indication that has no direct relation to reflected pulses from discontinuities in the materials being tested.
False indications (mt), английский
An indication of magnetic particles on the part held by gravity or surface roughness. it is neither caused nor held in place by leakage field.
