  2. Based on an analysis of the formation mechanism of induced current in underground pipelines, the author holds that, where underground media show very poor conductance, underground pipelines are dominated by magnetic dipole lines, and where underground media have certain conductance, pipelines are equivalent to electric wires

    摘要通過對地下管線中的感應電流形成機理分析,本文認為,當地下介質導電性很差時,地下管線以磁偶極線為主;而當地下介質存在一定的導電性時,管線則等效于電流線。
  3. When a cluster of particles is immersed in a uniform electric field, the particles are coupled together due to the mutual interaction among them. this interaction causes the dipole moment of the cluster to be dependent upon the spatial arrangement and relative permittivity of the particles and upon the cluster size. in this work, we attempt to estimate the dipole moment of finite cubic arrays of particles, in terms of that of particle chains which has been known. we assume that a chain may be replaced by a single equivalent sphere with the same dipole moment. with replacing the chain by equivalent sphere, a cluster is simplified to a planar array, and this planar array is simplified to a chain, then the dipole moment is obtained. numerical calculations are performed. it is found that our results are acceptable

  5. This method need less unknowns, less computer memory requirement and better error convergence rate compared with low - order mom, and maintain the virtue of high accuracy. a method for efficient generation of mom matrices based on equivalent dipole is also discussed. we combine these two methods
