On the basis of setting appropriate parameters, scanning single point energies are obtained by the same method and the potential energy curves under different external fields are also obtained. These results show that the physical property parameters and potential energy curves may change with external electric field, especially in the case of reverse direction electric field. The potential energy function without external electric field is fitted by Morse potential, and the fitting parameters are obtained which are in good agreement with experimental values. In order to obtain the critical dissociation electric parameter, the dipole approximation is adopted to construct a potential model fitting the corresponding potential energy curve of the external electric field. It is found that the fitted critical dissociation electric parameter is consistent with numerical calculation, so that the constructed model is reliable and accurate. These results will provide important theoretical and experimental reference for further studying the molecular spectrum, dynamics, and molecular cooling with Stark effect.展开更多

The experimental results indicate that TRIP steel exhibits good BH ability while DP steel does not, and prestrain displays a strong effect on the BH values of both steels. The comparison of microstructures of the two steels showed that the hard second phase in the matrix might be harmful to the BH ability. For deformed specimens, baking resulted in a loss of uniform elongation, but there was no obvious decrease in uniform elongation for unprestrained specimens.展开更多

In a second paper, we proposed a method to determine if the QCD gas density on black hole ergospheres grows in time and hence their ergoregions act as matter reactors that break matter and antimatter symmetry by trapping antimatter particles. In this paper, we suggest that quark and antiquark pair exchange reactions between particles and the QCD gas may accelerate or decelerate particles and that the quarks and antiquarks numbers are strictly conserved in these pair exchange reactions. We further suggest that antimatter plays a principal role in the universe and is inseparable from both matter, via Dirac’ spinors, and space, via the quarks and antiquarks pair exchange reactions with the QCD gas;however with a singular exception, black hole ergospheres separate and black hole ergoregions trap antimatter particles.展开更多

We propose that by mapping and simulating the cosmic web structure, it may be possible to learn if the universe was created in a single big bang that started a single chain of BH explosions mini-creation event cycles, or alternatively, the BH explosions mini-creation event cycles are uncorrelated spacelike events, and the universe had no single primeval atom beginning. .展开更多

BH should be accessible in the planned ILC and the observation of such particle can strongly support the littlest Higgs model. The realization of 7Y and e^-γ collisions would open a wider window to probe BH. In this paper, we study the new gauge boson BH production processes e^-γ→e^-BH and e^-γ→e^-BH at the ILC. Our results show that the production cross section of the process e^-γ→e^-BH is less than 0.1 fb in most parameter spaces allowed by the electroweak precision data while the cross section of the process e^-γ→e^-BH can be over one fb in the favorable parameter spaces. With the high luminosity, the enough typical signals could be produced via e^-γ→e^-BH. Because the final electron and photon beams can be easily identified and the signal can be easily distinguished from the backgrounds produced by Z and H decaying, e^-γ→e^-BH is a promising process to probe BH.展开更多
