According to relativity principle of special relativity via Lorentz transformation,on the basis of Coulomb law,the electric field force and the magnetic field force among moving charges were obtained skillfully.

Talk about how to use the virtual work principle to solve the relative problems of electrostatics,show it s simple,direct and convenient to use virtual work principle in working out electric field intensity,electric field force,moment of force.

By means of the finite element analysis,it indicates that the electric field force on impurities is on the boundary of the two phases medium and its direction is from the less dielectric constant to the bigger one.

Theoretical calculations of electrostatic force between ellipsoidal drops in W/O emulsion

The results indicate that the catalytic formation of the carbon nanotips results from deformation of the catalyst particles by the electrostatic force.

Sometimes only the electric force exists, sometines only the magnetic force exists, andsometimes the electric force and magnetic force exist at the same time.

A finite element model was proposed to investigate the electrical force acting on the nanotubes during the growth process and the dependence on CNTs height, inter-tube distance and diameter.

The process relies heavily on the electrostatic force produced by the depletion region, and a model is built to analyze the dominant factor of the electrostatic force.

The two-dimensional three-stage microbeam model subject to the electrostatic force is used to analyze effects of some factors on tunable-range of MEMS voltage-controlled capacitor.

A novel electromechanical integrated drive system actuated by electrostatic force was proposed,the basic operating principle of which was also described.
