中文摘要：

由于地球大气的吸收和发射，在空间进行红外观测显得更为重要。弥漫红外空间背景作为空间红外光电探测的背景噪声来源之一，是决定空间红外观测成败的一个重要因素。红外天文学对于弥漫红外空间背景的研究已经积累了丰硕的成果。本文基于地面及空间红外天文观测计划的成果，对国际天文界在弥漫红外空间背景性质方面的认识作了综述性的介绍，定量分析了弥漫红外空间背景各个组成部分的空间分布及观测特征，并列举了获取弥漫红外空间背景照度数据资料及具有实际应用价值的计算模型的徐径。

英文摘要：

Because of the absorption and emission by earth atmosphere, it is more important to conduct infrared observation in space. As one of the noise sources for space infrared opto-electronic detection, the diffuse infrared space background is an important factor to decide whether the infrared observation can be conducted successfully in space. The infrared astronomical community has accumulated a lot of achievements in the research on diffuse infrared space background. On the basis of the existing results of ground-based and space-based infrared astronomical observation programs, the widely accepted understanding of the diffuse infrared space background is presented. The spatial distribution intensity of each component of the diffuse space infrared background is analyzed quantitatively and the ways to access the diffuse space infrared background data and their calculation models are given.
