ABSTRACT The electromagnetic field with regard to velocity of a charged particle in arbitrary motion has been calculated in the paper. The distributional specialities and motion law of the electromagnetic field with regard to yelocity of the particle have been discussed as well.

The surface gravity of the charged BTZ black hole,the temperture and the Hawking spectra are given in this paper . It is shown that the angular velocity of the horizon and the electromagnetic vector potential play the role of the chemical potential.

In the paper, the charged mechanism , the equilibrium potential and the fragmentation criterien of dust grains in the cometary plasma have been discussed. ; and the electrnstatic disruption as well.

Solar particles such as 3 He,electrons and heavy ions with appropriate charge states are significantly heated by the H cyclotron waves with frequency ω=2Ω 3He preferentially.

The basic tool is the decomposition ofN pairs of free charged bosons with respect toglN and the commuting withglN Lie algebra of infinite matrices?l.

The results show that Langmuir and ion-acoustic wave are enhanced and the charged particles can be accelerated by the coupling of wave-wave.

A charged mesa, due to its reduced chemical potential, acts as a Coulomb sink and grows at the expense of neighboring neutral mesas.

In this article, we will describe in detail the proposed physical models, which can explain qualitatively the most salient features of coarsening of charged Pb mesas on the Si(111) surface, as observed by scanning tunneling microscopy (STM).

SCC susceptibility of pure copper in a 1 M NaNO2 solution was increased by pre-charged hydrogen.

Refinement of the Oblique Dipole Model in the Evolution of Rotary Motion of a Charged Body in the Geomagnetic Field

The evolution of the rotary motion of a charged rigid body in the geomagnetic field is considered, and the incorrectness of the oblique dipole model is demonstrated.

The electric field distribution around a charged satellite in a rarefied magnetospheric plasma influences greatly the densities and trajectories of particles measured by onboard instruments.

Secular evolution of rotary motion of a charged satellite in a decaying orbit

In the present work site-directed mutagenesis of the charged residues of cytochrome P450scc and adrenodoxin, which might be involved in interaction, was used to study the nature of electrostatic contacts between the hemeprotein and the ferredoxin.

It is taken into account that the charged condensation nucleus can be displaced from the mass center of the droplet to new equilibrium position inside the droplet under the action of external electric field and response field.

This transition is caused by the formation of ion pairs due to the binding of counterions with the charged groups of the polymer chain and is accompanied by a macromolecule collapse.

In this paper we discuss some properties of the metric field outside a rotating and charged object under VGM (The Theory of Gravitation by Considering the Vector Graviton Field and Metric Field). In Boyer-Lindquist coordinates the metric is expressed by equation (3) in the text. We come to the following conclusions: 1. According to the theory of VGM, it is impossible that a black hole possesses angular moment and charge, i.e. a rotating object, no matter whether it is charged, can not be a black hole. Therefore,...

According to the theory of VGM, it is impossible that a black hole possesses angular moment and charge, i.e. a rotating object, no matter whether it is charged, can not be a black hole. Therefore, both Kerr's black hole or Kerr-Newman's black hole can not exist in the Universe. 2. For a axisymmetrical object with angular moment and charge, there exists a critical radial coordinate distance relating to the angle where r_m=R_g(1+kQ~2/R_g~2), R_g(=GM/a~2, a half of Schwartzschild's radius) is the radius of a black hole without rotating or charge under VGM, a is J/Mc and J is the angular moment of the object, k=4πG/c~4, and Q is the charge of the object. For normal star similar to the sun which possesses charge about 100 coulomb, kQ~2/R_g~2～10~(-35) and r_m≈R_g. For the particles in the region r>r_k(θ) the metric field shows the behaviour of usual attraction, but for the particles in the region R

ID the late seventies, a "twin quasi-stellar object"[5] was discovered in the universe. The majority of astronomers considered it might be caused by the gravitational lens effect, an inference of the general theory of relativity. But, the gravitational theory proposed previously has not taken into account the influence of an electric field on the gravitation field. In this article,based on the general theory of relativity, the gravitational lens effect produced by the charged gravitation field is considered....

ID the late seventies, a "twin quasi-stellar object"[5] was discovered in the universe. The majority of astronomers considered it might be caused by the gravitational lens effect, an inference of the general theory of relativity. But, the gravitational theory proposed previously has not taken into account the influence of an electric field on the gravitation field. In this article,based on the general theory of relativity, the gravitational lens effect produced by the charged gravitation field is considered. The result shows that the lens effect of the charged gravitation field is smaller than that of the uncharged one; and therefore the quantity of electric charge of a celestial body can be determined.

In this paper we have obtained a metric which, containing five arbitrary functions of time, degenerates into Reissner-Nordstrom metric or Kinnersley[2] metric in special case, respectively. This metric describes the field of an arbitrarily accelerating charged point mass. It is a further generalization of the Vaidya star metric. This metric should have extensive meaning and may be useful for some kind of concrete models of celestial bodies
