Radiant cut, английский
- A brilliant cut fancy rectangular or square shaped diamond with its corners cut off. read worthy`s guide to radiant cut diamonds.
- The radiant cut is either a square or rectangle in shape, and like the emerald, the radiant cut is distinguishable by its blocked (cut) corners. the radiant is a beautiful combination of the classic emerald cut but with the faceted sparkle of the round brilliant or princess cut, because it combines the step cutting of the emerald with the triangular faceting of the brilliant cut.
Radiant energy, английский
- Laser energy emitted, expressed in joules (j).
- The amount of watts reaching a given point accumulated over a given
- Energy emitting as electromagnetic waves. also called radiation.
- Energy transmitted through a medium by electromagnetic waves. also known as radiation.
- Total energy, in joules, of electromagnetic radiation emitted by a source. radiant energy is determined by integrating radiant flux with respect to time. 510 glossary r
Radiant energy (q), английский
Energy in the form of electromagnetic waves usually expressed in units of joules (watt-seconds).
Radiant exposure (h), английский
The total energy per unit area incident upon a given surface. it is used to express exposure to pulsed laser radiation in units of j/cm2.
Radiant flux, английский
- The time rate of flow of radiant energy in units-watts
- The amount of power incident on a given surface, expressed in watts.
- Radiant energy’s rate of flow, measured in watts.
- Radiant energy’s rate of flow, measured in watts or joules per second (j/s). compare luminous flux.
Radiant gas -, английский
Инфракрасный газовый излучатель rail ~ машина для нагревания рельсов
Radiant glass, английский
Glass containing radiant heating elements.
Radiant heat, английский
- Heat energy carried by electromagnetic waves longer than light waves and shorter than radio waves; radiant heat (electromagnetic radiation) increases the sensible temperature of any substance capable of absorbing the radiation, especially solid and opaque objects.
- Heat energy carried by electromagnetic waves that are longer than light waves and shorter than radio waves
Radiant heat ignition, английский
Radiant heating, английский
- A method of heating, usually consisting of a forced hot water system with pipes placed in the floor, wall, or ceiling. also electrically heated panels.
- Heating which results from heat transmitted by radiation, as contrasted with heat transmitted by conduction or convection.
Radiant heating system, английский
A system for heating a room or space by means of heated surfaces (such as panels heated by the flow of hot water or electric current) which provide heat primarily by radiation.
Radiant intensity, английский
- The radiant power expressed per unit solid angle about the direction of the light.
- Electromagnetic energy emitted per unit time per unit solid angle.
- Electromagnetic energy emitted per unit time per unit solid angle. measured in watts per steradian.
- Electromagnetic flux emitted per unit solid angle in a given direction from the source. measured in watts per steradian (w/sr). compare luminous intensity.
Radiant intensity (power of source), английский
The amount of power from a point source generated
Radiant output, английский
Radiant panel test, английский
- An astm standard method of test for the surface flammability of a material, using a radiant heat source.
- A test for the flammability of carpets or rugs in which the specimen is mounted on the floor of the test chamber and exposed to intense radiant heat from above. the rate of flame spread is assessed.
- Flammability tests
- Radio-frequency drying: use of radio-frequency electromagnetic radiation for drying textiles
- The application of rf to wet goods results in the selective heating of the water, which has a partial polarity, because the molecule must do work to align in the rf field causing heat generation within the water droplets
Radiant power, английский
- Laser power emitted, expressed in watts (w).
- Total radiant energy emitted per unit time.
- See radiant flux.
Radiant temperature asymmetry, английский
Radiant-heated spray column, английский

Radioactivity leak test, английский
Leak test using radioactive tracer gas such as krypton-85, detected by its emission of radioactive decay products.
Quenching of fluorescence, английский
