Lepton epoch
- 轻子时期（轻子时期是宇宙演化早期的一个时期，宇宙由轻子主导。在大爆炸后1秒开始，在轻子时期的宇宙温度高，轻子/反轻子对仍维持热平衡。大约在大爆炸后10秒钟，宇宙温度降低，轻子和反轻子对不再产生，多数被消除，宇宙进入光子时期）
Lepton epoch

abstract:
In physical cosmology, the lepton epoch was the period in the evolution of the early universe in which the leptons dominated the mass of the universe. It started roughly 1 second after the Big Bang, after the majority of hadrons and anti-hadrons annihilated each other at the end of the hadron epoch.
