词汇 remanent
释义

Definition of remanent in English:

remanent

adjective ˈrɛmənəntˈrɛmənənt
  • (of magnetism) remaining after the magnetizing field has been removed.

    (磁性)剩余的,残余的

    Example sentencesExamples
    • Given the lag time between aeolianite deposition and the acquisition of chemical remanent magnetism, the East Naracoorte Range, which is reversely magnetized could actually have a minimum age exceeding 810 ka.
    • While the basalt pile is largely characterized by reversely polarized remanent magnetism, measurements on the Faeroe Islands demonstrate the presence of two significant intervals with normally polarized remanent magnetism.
    • There are, however, local weak remanent magnetic fields associated with some of the Moon's major impact basins that suggest that part of the core may still have been liquid and generating a global field when these formed 3.6 Ga ago.
    • Some samples revealed a steep low-temperature natural remanent magnetization component removed by temperatures higher than 150°C.
    • The direction and intensity of the remanent magnetization of the oriented samples before and after demagnetization were analysed using spinner magnetometers.
    Synonyms
    remaining, leftover, unused, unconsumed

Derivatives

  • remanence

  • noun
    • Coercivity of remanence, the back-field required to reduce a saturation remanence to zero, cannot readily be determined from hysteresis loop measurements and requires separate back-field measurements.
      Example sentencesExamples
      • We introduce the additional constraints of crustal isostasy to gravity models and the observations of the polarity of magnetic remanence within the lava pile to magnetic models.
      • To explore this possibility both the anisotropy of susceptibility and the anisotropy of magnetic remanence of the dykes were measured.
      • The fraction of the saturation magnetization which is retained when the driving field is removed is called the remanence of the material, and is the basis of data storage on audio and video tapes and computer hard drives.
      • Acquisition of the intermediate-temperature remanence in the dykes occurred during the greenschist-facies metamorphism, or during cooling at the end of the period of metamorphism and alteration.

Origin

Late Middle English: from Latin remanent- 'remaining', from the verb remanere.

Definition of remanent in US English:

remanent

adjectiveˈrɛmənəntˈremənənt
technical
  • 1Remaining; residual.

    〈技〉剩余的,残余的

    Example sentencesExamples
    • However, a related property, the coercivity of remanent hysteresis, which is determinable from the hysteresis loop, has been shown to be an adequate estimator of the coercivity of remanence.
