A review is presented of research and development of gas discharge and non equilibrium plasma including, new ideas of non equilibrium plasma at high gas pressure. With special technology, strong electric fields(>400Td) can be achieved by which electrons are accelerated suddenly, becoming high energy electrons(>10eV) at high pressure. On impact with the electrons, the gas molecules dissociate into ions, atomic ions, atoms and free radicals, and new substances or molecules can be synthesized through custom design. Chemical reaction difficult to achieve by conventional method can be realized or accelerated. Non equilibrium plasma chemistry at high pressure has wide application prospects.
