In this paper, the current situation, development trend and existing problems of electric field ionization gas under high pressure are summarized. The theory and method of high ionization discharge under high pressure are emphatically studied. Using extreme physical methods and special technological means, a strong dielectric barrier discharge with equivalent electric field intensity E / n> 350dat and electron average energy Te> 10eV is formed in the discharge gap, which is enough for the majority of gas molecules to decompose and ionize Such as electrons, photons, ions, free radicals and active atoms, excited atoms and active molecular fragments, to provide single-molecule chemical active particles; and then at the molecular level according to pre-designed model of processing of new materials, new materials for its chemical Industrial, environmental engineering and materials industry applications provide theoretical basis and technical means.
