radiant intensity in a sentence

"radiant intensity" in Chinese  

SentencesmobileMobile

  • A spectral plot represents radiant intensity versus wavelength at an instant in time.
  • Light with the same radiant intensity at other wavelengths has a lower luminous intensity.
  • For example, radiant intensity can be measured in watts per steradian ( W穝r  " 1 ).
  • In radio-frequency engineering, radiant intensity is sometimes called "'radiation intensity " '.
  • Wien's displacement law determines the most likely frequency of the emitted radiation, and the Stefan Boltzmann law gives the radiant intensity.
  • A "'radiometric plot "'represents the radiant intensity versus time; there can be plots at multiple bands or wavelengths.
  • When calculating the radiant intensity emitted by a source, " ? " refers to the solid angle into which the light is emitted.
  • The term can refer to any of irradiance, luminous intensity, radiant intensity, or radiance, depending on the background of the person using the term.
  • In optics, "'Lambert's cosine law "'says that the radiant intensity or luminous intensity observed from an ideal surface normal.
  • The contrast radiant intensity method of defining infrared signature is to take the difference in average radiance of the object and that of the immediate background and multiply this by the projected area of the object.
  • It's difficult to see radiant intensity in a sentence .
  • Two fairly successful examples of defining the infrared signature of an object are the "'apparent temperature difference "'at the sensor and the "'contrast radiant intensity "'( CRI ) definitions.
  • This is usually due to the lower radiant intensity of the objects being measured as well as the difficulty of measuring light at higher energies using its particle-like nature as compared to the wavelike nature of light at lower frequencies.
  • As ytterbium ( III ) oxide has a significantly higher emissivity in the infrared range than magnesium oxide, a higher radiant intensity is obtained with ytterbium-based payloads in comparison to those commonly based on magnesium / Teflon / Viton ( MTV ).
  • For each point along a time-intensity radiometric plot, a spectral plot can be generated based on the number of spectral bands in the collector, such as the radiant intensity plot of a missile exhaust plume as the missile is in flight.
  • Unlike power density, radiant intensity does not depend on distance : because radiant intensity is defined as the power through a solid angle, the decreasing power density over distance due to the inverse-square law is offset by the increase in area with distance.
  • Unlike power density, radiant intensity does not depend on distance : because radiant intensity is defined as the power through a solid angle, the decreasing power density over distance due to the inverse-square law is offset by the increase in area with distance.
  • Directive gain is represented as D ( \ theta, \ phi ) and compares the radiant intensity ( power per unit solid angle ) U ( \ theta, \ phi ) that an antenna creates in a particular direction against the average value over all directions:
  • Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function ( a model of the sensitivity of the human eye to different wavelengths ).
  • In radiometry, "'radiant intensity "'is the radiant flux emitted, reflected, transmitted or received, per unit solid angle, and "'spectral intensity "'is the radiant intensity per unit frequency or wavelength, depending on whether the intensity " in branches of physics other than radiometry.
  • In radiometry, "'radiant intensity "'is the radiant flux emitted, reflected, transmitted or received, per unit solid angle, and "'spectral intensity "'is the radiant intensity per unit frequency or wavelength, depending on whether the intensity " in branches of physics other than radiometry.
