摘　　要：对多景NOAA/AVHRR影像的研究发现:CH3波段不仅可以提取高温信息,而且还可以提取常温状态下的物类信息,并且在很多情况下优于CH4波段。文章给出了具体分析,并进行了原因探讨。Based on detailed studies of quite a few NOAA/AVHRR images, it is found that the image of channel 3 could be used to extract not only the information of high temperature objects but the information of normal temperature objects as well, and that in many cases it is better than the image of channel 4 in the information extraction. In this paper the authors have also made a concrete analysis and probed into the causes of such a phenomenon.
