摘要/Abstract

摘要：为了解决宇宙大爆炸标准模型与观测实验的困难，提出了宇宙暴胀模型，要求宇宙于１０^－３５　ｓ、能标为104　GeV时发生暴胀，暴胀使能标降到109　GeV左右，于１０^－３２　ｓ暴胀结束宇宙又重新加热到104　GeV.一种可能的解释是：当时刻为１０^－３５　ｓ时，费米型夸克Ｔ２／３Ｆ的超对称伴子Ｙ＋２／３ＴＢ，Y-＋２／３ＴＢ对发生湮灭转化为光子对，使宇宙背景能量突然上升所致.

关键词： 宇宙暴胀, 相变, 宇宙重新加热, 超对称, 宇宙早期核子

Abstract: In order to over come the difficulty of the big bang model of the universe not tallying with the observation and the experiments,the universe inflation model was put forward,which requires that the inflation of the universe take place at the time １０^－３５　ｓ and the energe scale 104　GeV,the energy scale decrease to 109　GeV due to the inflation,and the universe be heated again to 104　GeV at the time １０^－３２　ｓ　after the inflation ended.One of possible explanations is that at the time １０^－３５　ｓ the pairs of the supersynunetry companions Ｙ＋２／３ＴＢ and Ｙ－＋２／３ＴＢ of Fermi type quark Ｔ２／３Ｆ were annihilated and converted into pairs of photons and the back ground energy of the universe abruptly rose.As a result of it,the universe was heated again and inflated.

Key words: universe inflation, phase transition, re-heating of the universe, supersymmetry, early universe nucleon
