The ELF magnetic field generated by a video terminal measures only a few milligauss, or about one-hundredth the strength of the earth's own magnetic field, The electric fields surrounding a power line can be as high as 10 kilovolts per meter, but the corresponding field induced in human cells will be only about 1 millivolt per meter.

The dynamic behavior of an individual polymer chain in the confined system or environment (the extension of a single polymer chain which one end is fixed under the electric field, the translocation process of a single Gaussian chain through a nanometer-scale pore under the electric field, spontaneous recoil of a single chain located in the confined environment) was studied by using Monte Carlo computer simulation. The simulation results can be used to investigate the kinetic law of molecular chain polarization, dipole relaxation and trapped charge carrier under the application of electric field.

Given a mesh, we first solve a Poisson equation to construct a scalar field and use it to generate some critical points. The cutting paths between the critical points and the boundaries are solved in the Poisson scalar field using the deepest descent method. For meshes with nonzero-genus, we construct a Harmonic scalar field, and connect the saddle points with the boundaries based on the Morse theory.

Second, thestress-type ABC indicates that the ABC is an expression of interaction stress betweenthe near-field finite domain and the far-field infinite domain. It can compatible withthe finite element method very well as a natural stress boundary condition, leading tothe numerically stable near-field wave motion method.

Numerous impermeable underground structures exist in urban seepage field. Since the corner of the structure is singular point and the dimension of the structure is negligibly small compared with the whole urban seepage field, it is difficult to model seepage field in urban area with existing methods.

In this paper an analysis has been made to some regions of magnetosphere, including the Nightside, Cusp and Duskside. By applying the Curvature Radius Method to the magnetic field data measured by four satellites of Cluster, the geometrical structure of Magnetic Field Lines, including the curvature radius, directions of curvature and normal of the osculating planes of the Magnetic Field Lines have been investigated.

Finally, we present an arithmetic of multiplehypocentral, heterogenous dislocation, and a multirupture segment superposition model for simulating the earthquake deformation field. The simulated LOS interferometry map presents the distribution characteristics of the earthquake deformation field better than that of previous studied. Meanwhile, a suit of fault geometric parameters of the earthquake is also obtained by the study. Having a better effect upon simulating asymmetry, great dislocation, macro rupture field, and nonhomogeneity of dislocation than the traditional model, the multisegment method is a progress of this work. It provides a better explanation for the study on hypocentral parameters.
