解釋
偶極電源-
The current trends of this field is to acquire the current density of dipole distribution rather than a few dipoles. based upon that, a new model was proposed - dipole layer localization method ( dllm ) : spherical dipole layer was used as source model, on which dipoles were distributed by equilateral triangles ; three concentric inhomogeneous sphere was used as head model, which contains scalp, skull and cortex with different conductance. the dipole distribution and scalp potential tomography were obtained with singular value decomposition ( svd )
鑒于該領域的研究趨勢已從求取少數偶極子過渡到偶極子分佈密度的獲得，本文提出了新的模型? ?偶極面定位方法（ dipolelayerlocalizationmethod ， dllm ） ：以等邊三角形均勻分佈的偶極子構成的偶極面（球面）作為源模型；包括頭皮、顱骨和皮層的三層同心介質球作為頭顱模型，運用奇異值分解來求解逆問題，從而獲得偶極子分佈和頭皮電位分佈，實現三維成像。 -
Based the basic principle of the accumulation of induced electric charges across the resistivity discontinuities and the induction current channeling inside the conductive bodies inspirited by the mt field, we set up the relation between the measured field on the earth surface and the distribution of the induced source underground by means of the defining the electric charge occurrence probability function and the electric dipole occurrence probability function and the spacial distributing of the " correlation probability ". the " image " of the field sources underground, or the distributing graphy of the induced electric charges and the induced current in the mesuring area can be drawed, from which we can get the outline of the geological anomaly on the meaning of the probability
大地電磁場概率成像方法是一種新的地球物理成像反演方法，它是根據在大電磁波場的激勵下，地下介質電阻率間斷處產生感應電荷積累和導體內部產生感應電流，從而產生感應電磁場的原理，相應地定義了感應電荷發生概率函數和感應電偶極子發生概率函數，通過「相關概率」發生的大小的空間分佈，建立了地表觀測場與地下場源空間分佈的內在聯系。地下場源分佈概率的「像」 ，即測區的感應電荷和感應電流的概率的分布圖像，就是測區內地質體在概率意義下地質異常體的分佈輪廓。 -
