  • 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。
  • field : n 菲爾德〈姓氏〉。n 1 原野，曠野；（海、空、冰雪等的）茫茫一片。2 田地，牧場；割草場；〈pl 〉〈集...
  1. Output can be obtain, next we use our designed the wavelet soft threshold to select result of the wavelet transform, finally, we give the selected result reversal wavelet transform. it is obvious : the wavelet soft threshold is important to improve the quality of the gray image processing. i give the donoho wavelet soft threshold a modified value method, which has a relation with ratio of signal - noise. i made full use of discrete hop field single feedback neural network, and nonlinear steady of automatic system at last, i obtained a steady limited ring, give the energy function an order differential a optimal

    我的思路是：改造現有圖形結構，先建立能反映信噪比大小且含待定參數k的表達式，然後通過離散型h0pfi舊單層反饋神經網路，再結合前邊的混合濾波器構成一個非線性控制系統，寫出對應的網路函數，利用相平面法和李雅普諾大穩定性的判據，得到一個穩定的極限環，從而確定出參數卜的范圍，進而再對原來的小波軟閾值進行修正，用修正後的值作為小波閾值。
  2. A reversal could knock out power grids, hurt astronauts and satellites, widen atmospheric ozone holes, send polar auroras flashing to the equator and confuse birds, fish and migratory animals that rely on the steadiness of the magnetic field as a navigation aid

    逆轉會破壞能量網格，損害宇航員和衛星，加大臭氧層空洞，發送極光到赤道而搞亂鳥類，魚和遷徙動物，它們依靠磁場的穩定性作為導航幫助。
  3. No seismic reflection wave imaging technology, as well as the crustal rocks and the ocean ridges residual magnetic field sensors return reverse, there is no better explanation, can only use " earth ' s magnetic field reversal " to explain this phenomenon in order to cover up the phenomenon nature of the problem

    也沒有地震反射波的成像技術，以至對地殼巖石和大洋洋脊的感應剩磁場來回反向問題，沒有更好的解釋方法，只能用「地球磁場逆轉」來解釋此現象，以現象掩蓋了本質問題。
  4. 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。
  5. 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。
  6. The method to determin reversal electric field was provided, and on the base of experiment data in this method, a new periodicity poled waveform and period was designed

    根據該方法的實驗數據設計出了一種新的周期性極化波形和周期。實驗的結果有:通過實驗測出了slt晶體的極化反轉電壓為1 . 6kv / mm 。
  7. In order for a reversal to take place there must be a brief time during which the field is non - existent

    為了發生一次倒轉，必須有一個很短的時間沒有磁場存在。
  8. One three - dimensional simulation ? which had to run for 12 hours a day every day for more than a year to simulate 300, 000 years ? depicted the onset of a reversal as a decrease in the intensity of the dipole field

    一個三維的模擬（必須每天運算12小時，並且持續一年，才能得出30萬年的模擬結果）所描繪出的反轉事件，是開始於偶極場強度的衰減。
  9. Abstract ； on the " earth ' s magnetic field reversal " one said, we have not experienced a human nor historical records

    摘要；關于「地球磁場逆轉」一說，我們人類並沒有經歷過，也沒有歷史記載。
