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10-35s、能标为1014 GeV时发生暴胀,暴胀使能标降到109 GeV左右,于10-32s暴胀结束宇宙又重新加热到1014 GeV.一种可能的解释是:当时刻为10-35s时,费米型夸克TF2/3的超对称伴子YTB+2/3,YTB+2/3对发生湮灭转化为光子对,使宇宙背景能量突然上升所致.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 10^14 GeV,the energy scale decrease to 109 GeV due to the inflation,and the universe be heated again to 1014 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 YTB^＋2/3 and Y^-TB^＋2/3 of Fermi type quark TF^2/3 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.
