如果QCD相变是一阶的，那么热电机制在早期宇宙中产生磁场。通过合理的跃迁参数，发现当宇宙温度在150 MeV左右时，可以在1 m尺度上形成5-G磁场。这些原始场是QCD相变的结果，在星系形成开始时的大小约为2 × 10的-17次方G。参43。
If the QCD phase transition is first-order, then a thermoelectric mechanism generates magnetic fields in the early universe. For reasonable transition parameters, it is found that 5-G magnetic fields could form on scales of 1 m when the temperature of the universe was around 150 MeV. These primordial fields, a consequence of the QCD phase transition, have a magnitude of about 2 x 10 to the -17th G at the time when galaxy formation begins. 43 refs.
