  1. So it is necessary to reflect the inner reality physical field ' s numerical number analogy method to analysis and improve the magnetic field and the computing accuracy of the cable ' s eddy - current detection. Ｔ his affords helping for the researching of biased cable instrument in the future. first open domain electric magnetic problem ' s breaking method is done with, which supposing fictitious boundary far away from the region. second breaking the infinite region into the finite region and supposing the electric magnetic is too small to be ignored

    通過採用目前處理開域電磁場問題的截斷法，人為地設定一個遠離待求區域的虛擬邊界，將無限區域截斷為有限區域，且認為在該邊界外面的電磁場已衰減得足夠小，小到可以忽略不計，從而令邊界上的電磁場場量為零，在此有限區域內採用較為成熟的Ａ ， Ａ法，並且併入庫侖規范建立數學模型。
  2. The fbc for connecting the subdomains on fictitious boundary is developed according to the actual field distribution in the waveguide to ensure the propagation of waves between adjacent subdomains. the relaxed algorithm is introduced to improve the iterative convergence

    文中從實際場分佈出發，在劃分區域的虛擬邊界上給出了連接子域的吸收虛擬邊界條件，並通過引入鬆弛演算法，構建了一種能夠用於分析波導問題的鬆弛迭代區域分解法。
  3. Secondly, the physical nature of divergence of iterative ddm based on the schwarz alternating method in treating waveguide problems is given in this paper. also an absorbing fictitious boundary condition ( fbc ) is presented to generate an iterative ddm for waveguide problems

    其次，針對helmholtz方程微分運算元的系數矩陣非正定，基於schwarz交替法的迭代區域分解法，在分析波導問題時迭代不收斂的困難，探討了產生這一問題的物理本質。
