polarity reversal 中文意思是什麼

polarity reversal 解釋
反極性
  • 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。
  • reversal : n. 1. 顛倒，倒轉，反轉，逆轉，反向；反復。2. 【法律】撤消。3. 【攝影】正負片之間的轉換。
  1. 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。
  2. During a reversal, the main field weakens, almost vanishes, then reappears with opposite polarity

    在逆轉期間，主磁場減弱，幾乎為零，然後以相反的磁極重新出現。
  3. 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。
  4. Despite the inherent limitations, several noteworthy observations came out of these efforts, including hints about the possible onset of a new polarity reversal

    盡管在此既有限制之下，研究人員仍然得到了許多重要的觀測結果，包括關于磁極可能開始反轉的線索。
  5. Viewed at the surface of the model earth, the reversal of the dipole occurred when the reversed flux patches begin to dominate the original polarity on the core - mantle boundary

    由模型中的地球表面看來，磁偶極的反轉是發生於地核?地函交界上反向通量斑塊開始超過原本的極性時。
