The production of pairs of monopole–antimonopole in presence of extremely intense magnetic fields, is briefly investigated in the case where the magnetic field undergoes also a time variation. The possibility that similar conditions are realized, with a production of ordinary particles, was already considered for astrophysical phenomena, e.g. some phases of evolution of neutron stars.

在非常强烈但缓慢变化的磁场中产生单极-反单极对

在磁场也经历时间变化的情况下，简要研究了在极强磁场存在的情况下单极-反单极对的产生。对于天体物理现象，例如中子星演化的某些阶段，已经考虑了通过产生普通粒子实现类似条件的可能性。
