- 本文以強引力的de Sitter度規和Einstein-Yukawa理論的Reissner-Nordstrom度規為例,討論了在原子核內或在強子內Dirac粒子的真空禁帶能隙,結果表明,在強引力下,粒子的真空能隙形成一個(gè)勢阱.In this paper, we discussed the vacuum gap of Dirac particle in the interior of a atomic nucleus and of a hadron. Results of the calculating showed that the vacuum gap is as a potential well, whether in de Sitter metric for the case of strong gravity, or in Reissner-Nordstrom metric for the case of yukawa field.
