The result of our experiment on Rb atoms is interesting and surprising .To affirm or to refuse the result should not be by conjectures but by experiments.  相似文献

Based on the hydridic Earth model, we propose a hydridic model of the Earth’s electric field. The model predicts that the negative electrode of the Earth’s capacitor is located under the Earth’s crust and the Earth’s fluids carry a positive charge. We have observed an excess of positive charge in the Earth’s crust down to kilometer depths. The model explains the unitary variation of the fair-weather atmospheric electric field strength, the change in atmospheric electric field strength and the precipitation of high-energy electrons during earthquakes.  相似文献

It is stated that the conjecture that the hydrogen-like atoms may have large permanent electric dipole moments is doubtable.Two kinds of experiments are suggested to check the reliability of the conjecture further.  相似文献

Effects of dipole moment on the horizontal dust lattice waves in one-dimensional dust chain are investigated. The general dispersion relations are derived. The waves are sensitive to the direction of the dipole moment, which has an angle θ (0≤ θ≤π) with respect to the vertical direction. When the waves are self-excited, it is shown that the real part of frequency for longitudinal wave is increased, while it is decreased for the horizontal transverse wave with increasing θ. When the waves are externally exited, both the real and imaginary parts of wave number are decreased for the longitudinal and transverse waves with increasing θ.  相似文献

Flows of material particles, viz., cosmic rays and cosmic dust, are perpetually coming from space into the Earth’s atmosphere; these are particles sized from 0.001 μm to dozens or hundreds of μm. The paper shows that cosmic rays influence the main parameters of the atmosphere’s electricity, and cosmic dust influences global cloudiness, albedo and the Earth’s climate. Original Russian Text ?

The electronic structure of the quantum-dot molecules in an electric field is investigated by the finite element method with the effective mass approximation.The numerical calculation results show that the valence bond of the quantum-dot molecule alternates between covalent bonds and ionic bonds as the electric field increases.The valence-bond property can be reflected by the oscillator strength of the intraband transition.The bound state with the highest energy level in the quantum-dot molecule gradually changes into a quasibound state when the electric field increases.  相似文献

The influence of the Earth’s gravitational field on a weakly relativistic electron involved in the process of generation of microwave radiation is evaluated. It is shown that such exposure leads to the generation of a second harmonic.  相似文献

Earth??s field nuclear magnetic resonance (NMR) can be used for non-destructive in-bottle liquid screening by evaluating the spin?Clattice relaxation times of protons in various liquids. An Earth??s field NMR apparatus has been developed and optimized to measure the spin?Clattice relaxation times of various liquids contained in 500?ml PET bottles. Two methods to generate 90-degree readout pulses using transient oscillating signals generated in a resonator are reported. The lower detection limit of pure water was 1?ml. The minimum measurable spin?Clattice relaxation time was 50?ms.  相似文献

The methods of theoretical and celestial mechanics and mathematical statistics have been used to prove that the Earth’s motion relative to the center of mass, the polar wobble, in the principal approximation is a combination of two circumferences with a slow trend in the mean position corresponding to the annual and Chandler components. It has been established that the parameters (amplitude and phase shift) of the annual wobble are stable, while those of the Chandler component are less stable and undergo significant variations over the observed time intervals. It has been proven that the behavior of these polar motion parameters is attributable to the gravitational-tidal mechanisms of their excitation.  相似文献

In this paper, it is shown how free induction decay signals recorded in the Earth’s magnetic field from water protons confined in porous media can be used to derive transversal relaxation times (T 2) and their distributions. After T 2 determination of six sintered glass samples with various pore sizes, the common theoretical model can be fitted to the data set. The T 2 distribution of water protons in a bimodal porous system is analyzed and compared to mercury porosimetry results. The implications for the calculation of pore sizes and pore size distributions of porous media by this method are discussed.  相似文献

The effects of the external electric field on the ferroelectric superlattice with two alternating layers have been studied using the transverse Ising model based on the effective-field theory with the differential technique. The hysteresis loops and susceptibility of the system have been given. The stronger the external electric field, the smaller the susceptibility, reflecting that the polarization is weaker.  相似文献

Four kinds of solar indices F10.7, E10.7, S10, Mg10 and four thermospheric neutral density models, i.e., CIRA72, DTM94, NRLMSISE00 and JB2006, are discussed. The CHAMP accelerometer data are used to calculate thermospheric total mass density. Based on the comparison of the model densities with CHAMP observations, the effects of various indices on the model accuracy are detected. It is found that under quiet and moderate solar conditions (F10.7<160), all of the models’ errors are reduced about 15% by using E...  相似文献
