For the benefit of a electronic-positron structure the representations about an annihilation of the electronic-positron pairs, formation in substance electronic-positron of pairs under activity action of a gamma radiation, electronic and positron character of a beta radiation in nuclei are worked. Terminology： positrino, electrino, pairino. The new mechanism of a physical phenomenon, well explored to the present moment, with the conventional interpretation - mechanism of an annihilation of a free positron on electrons of substance is offered. That is the conventional point of view is those, that during annihilation the electron bums down, disappears or is transmuted into a gamma-quantum. In opinion of the author any facts or the proofs of such interpretation do not exist. The following mechanism therefore is offered： an electron and positron at coming together are discharged by two gamma-quantum and form pairino （unloaded electron - positron state with gravitational mass ＂m＂ about 2 eV, with compensation by electric charge, about an electrino by positrino interaction）; that is the mechanism ＂cold＂ （low, is less than 10 KeV, energies） synthesis of pairino. The given mechanism of phenomenon of annihilation is more realistic.展开更多

Our results show that the impact of each of the three foundational factors (the environ- mental current, the asymmetric structure and the asymmetric convection system) on TC track varies with time and the im- portance of each of the factors is different for the different TC motion time period. They show two kinds of the effects. One is a direct way. The asymmetric outer wind structure and the positive longitudinal wind speed averaged in radial-band (100-300) km in the period of (0-11) h are caused by the introduction of the initial brows-like meso-scale vortex, which results in TC track to turn to the north from the northwest directly. The other is an indirect influence. First, initial TC axisymmetric circula- tion becomes a non-axisyrnmetric circulation after the addition of the meso-scale vortex. The initial non-axisymmetric circula- tion experiences an axisymmetrizational process in the period of (0-11) h. Second, axisymmetrizationed TC horizontal size is enlarged after t=-12 h. Third, both the TC asymmetric structure and the TC energy dispersion induced-anticyclone are intensi- fied, which quickens the TC motion and results in the track to turn to the north indirectly. The TC motion is characterized by the unusual track under the direct and the indirect effect. The formation of the unusual track should be attributed to the com- mon effects of three factors, including the environmental flow, the TC asymmetric structure and the asymmetric convection system.展开更多
