摘　　要："实践八号"乳胶室探测器是我国首次用于空间观测高能电子及伽玛射线的乳胶室探测器.介绍"实践八号"乳胶室探测器的设计原理、数据分析方法、设计过程和初步观测结果等."实践八号"乳胶室探测器空间观测时间为15天,可探测的粒子能量范围为100 GeV～5 TeV.At present, the research on dark matter is the cutting edge of science. It is the hotspot to find out if the dark matter exist in the form of particle by observing the electrons and γ-rays resulted from the disintegration or reciprocity of dark matter. Emulsion chamber is a powerful detector for high-energy electrons and γ-rays with high special and energy resolution. As one of the payloads of ＂ShiJian eight＂ satellite, the emulsion chamber detector is the first one in China designed for space observing the high-energy electrons and γ-rays. In this paper, several problems are discussed, such as the design principle of the detector, data analysis, process of designing and some results of this experiment. The design life of this detector is about 15 days in its orbit, and the energy range of the particle detected by the emulsion chamber is about 100 GeV to 5 TeV.
