| 摘 要： | 本文研究了引力透镜和富星系团在宇宙中作为一种分布,对红外背景畸变的统计效应。其中包括富系团的热电子对红外背景畸变的Sunyaev-Zel’dovich效应,以及引力透镜对红外背景畸变的引力效应。本文给出了z=4范围内的红外背景的总畸变,其结果是:Sunyaev-Zel’-dovich效应为:(△T_r)/T_r～10~(-2)—10~(-3),纯引力效应为(△T_r)/T_r～10~(-3)—10~(-4)。

| Abstract: | In this paper, we discuss the statistical effect of the IR background distortion due to gravitational lens and rich galactic clusters, both of which have a definite distribution within the universe. The effect includes the distortion on IR background due to the Sunyeav-ZePdovich effect of the hot electrons in rich galactic clusters and that due to gravitational effect of gravitational lens. The total distorition within Z-4 is presented. The conclusions are (1) thedistortion due to the Sunyaev-Zel'dovich effect is ; (2) the distortion due tothe gravitational effect of gravitational lens is . |
