释义

Definition of radiometric in English:

radiometric

adjective ˌreɪdɪə(ʊ)ˈmɛtrɪkˌreɪdiəˈmɛtrɪk
Physics
  • Relating to the measurement of radioactivity.

    〔物理〕辐射测量的,辐射度的

    radiometric data
    Example sentencesExamples
    • A single UVB - 1 sensor in the field can experience a change in overall radiometric sensitivity or gain during the year between successive calibrations.
    • Both events clearly post-date the lower Rotliegend volcanism in the Southern Permian Basin where the volcanics give radiometric ages in the range 288300 Ma.
    • No radiometric technique that is capable of measuring on that large a time scale can narrow down ages within 10,000 years.
    • Both radiometric and biostratigraphic data indicate the onset of magmatism in late Mid-Jurassic time.
    • Fossils are almost never dated by radiometric methods, since they rarely contain suitable radioactive elements.
    • Dumyahn and First measured the three-dimensional emission profile of various types of single lamps by taking radiometric measurements at various points in space.
    • No radiometric data have been obtained from Stage III rocks.
    • Our interest was mainly in the spectral signature of the system, not the absolute radiometric values of the irradiance; thus, distances and angular content did not concern us.
    • Thermal images were taken with a radiometric infrared video camera.
    • The age of the intrusion is also well constrained by several radiometric analyses.
    • This cannot be a simple application of the photometric and radiometric test methods used for other conventional light sources, for several reasons.
    • All of these factors are likely to be important in the case of the Besdegirmen rocks, and hence igneous crystallization ages may be greater than measured radiometric ages.
    • It comprises several mafic, mafic-felsic and felsic intrusions with distinctive geochemical affinities and apparent radiometric ages.
    • Microwave sensor data, thermal and radiometric information etc. can be got even under adverse weather conditions or cloud cover.
    • Numerous radiometric age determinations are now available to help unravel the evolution of the East Greenland Caledonide orogen.
    • The sediments of the Grensen Formation are barren of all organic material and hence must be dated using radiometric and petrographic evidence alone.
    • We have an extensive radiometric dataset from the garnet gneiss, summarized in Table 4.
    • The Institute Nacional de Meteorologia provided the radiometric, columnar ozone and meteorological information for the three stations used in this study.
    • The temperature-time plot shows how this model also fails to satisfy the radiometric data.
    • We note the peak axial radiometric temperature difference between irradiated and nonirradiated surfaces of these specimens was approximately 10 degC.

      Example sentencesExamples
      • Almost all meteorites are collisional fragments of asteroids, and can be dated radiometrically to about 4.6 billion years, which represents the birth of the Solar System.
      • Thus basin evolution can be readily linked to geochemically and radiometrically constrained volcanic arc development.
