| 摘 要： | Blazar高能伽马射线在宇宙传播过程中,将会和宇宙背景光子发生相互作用,从而能量会有一个降低的过程。文章将在理论上计算和分析宇宙微波背景（CMB）和河外背景光（EBL）对高能伽马射线的吸收过程,并讨论二者对不同红移情况下的高能伽马射线的吸收过程。

| Abstract: | The high-energy gamma rays can be absorbed by their interaction with the photons of extragalactic background light(EBL)and cosmic microwave background(CMB) when they radiate in the universe,with the energy of the gamma-ray photons falling down in this process.In this thesis,we will calculate the optical depth of gamma-rays from interaction with the photons of the EBL and CMB,and discuss the optical depth change with the different redshift. |
