magnetic polarity 解釋
磁極化
  • magnetic : adj. 1. 磁（性）的；（可）磁化的。2. 吸引人心的；有魅力的。3. 催眠術的。
  • polarity : n. 1. 【物理學】（分）極性，磁性引力；（光的）偏極；極體；【數學】配極（變換）；【生物學】（莖與根的）反向性，極性。2. （性格的）正反對。3. （思想、感情等的）歸向，傾向。
  1. When the sun's rotation sweeps this warped surface across the earth, we detect sudden changes in the polarity of the magnetic field.

    當太陽的自轉使這個波浪形間隔面掃過地球時，我們就會探測到磁場極性的突然反轉。
  2. Magnetic minerals trapped inside ancient rocks have recorded hundreds of these so - called polarity reversals in the past 500 million years

    在地磁反轉后，指北針的指針會指向南極，而不再是冰凍的北極。
  3. Deltan heliographers observe an irregularity in the magnetic cycle of the star delta. the shift of the stars magnetic polarity which usually occurs every 12 years has occurred 1 year early

    德爾塔日光儀觀察到星球德爾塔的磁極周期不規則性變化；該星球每12年移動一次的磁極變化剛剛在一年前發生過。
  4. For an actual planetwide polarity reversal to occur, such a reversed flux patch would grow and engulf the entire polar region ; at the same time, a similar change in overall regional magnetic polarity would take place near the other geographic pole

    如果整個行星的磁極要真的反轉，反向通量斑塊需擴大到涵蓋整個極區；同時，另一個地理極點附近也會發生類似的區域極性全面變化。
  5. Magnetic field polarity reversals are magnetic poleshifts

    磁場極性逆轉就是磁極轉換。
  6. Only on rare occasions do the thermodynamics work ; the fluid motions and the magnetic field all evolve in a compatible manner, so the new dipole polarity can diffuse in and establish a reversed magnetic field

    只有在很少的情況下熱力學才發揮作用，此時流體運動和磁場都會以相互訪調的方式演化，這樣新的偶極性就會散開並建立一個倒轉的磁場。
  7. When a ferromagnetism items is under the application of stress, the phenomenon that the tangential component of magnetic leakage field has maximum value and that the normal component of magnetic leakage field changes polarity and acquires zero value at the stress concentration zone will take place

    鐵磁性工件在受到應力作用時，在應力集中處會有漏磁場的切向分量出現最大值、同時法向分量改變符號且過零值點的現象。
  8. But scientists need additional evidence to answer the puzzling questions about the magnetic field that emerges ? and why it would change polarity over time

    但科學家需要更多證據來解釋令人困惑的問題，像是磁場的生成，以及為什麼磁極會隨時間而改變等。
  9. This paper introduces the formation of magnetic field, polarity reversal, secular variation and the use of geomagnetic polarity reversal or susceptibility in stratigraphic study

    摘要本文介紹了地球磁場的成因、極性變化以及運用極性倒轉劃分對比地層和指示環境。
  10. Mixed - polarity magnetic field

    極性混合磁場
  11. Based on the multi - shelves thermal demagnetization, magnetic test, directional analysis, the paper has drawn the paleo - latitude map and contrasted it with international standard polarity pole on the basis of the volcano rock age

    經過巖心的多檔熱退磁及磁性測試和定向分析，繪制出古極緯度圖，在參考火山巖同位素年齡的基礎上，將古極緯度柱與國際標準極性年表進行對比。
