暗物质粒子探测器（DAMPE）是一个星载高能粒子和射线探测器，致力于间接探测粒子暗物质和研究高能天体物理。最近发表了25 GeV ~ 4.6TeV宇宙线正负电子能谱的首次精确测量结果。DAMPE谱在0：9 TeV附近出现了一个有趣的谱软化现象，在1：4 TeV附近出现了一个试探性的峰。这些结果引发了广泛的讨论。介绍了DAMPE的探测器、数据分析和初步结果。特别是，DAMPE数据的物理解释进行审查。
The DArk Matter Particle Explorer (DAMPE) is a satellite-borne, high-energy particle and -ray detector, which is dedicated to indirectly detecting particle dark matter and studying high-energy astrophysics. The first results about precise measurement of the cosmic ray electron plus positron spectrum between 25 GeV and 4.6 TeV were published recently. The DAMPE spectrum reveals an interesting spectral softening arount 0:9 TeV and a tentative peak around 1:4 TeV. These results have inspired extensive discussion. The detector of DAMPE, the data analysis, and the first results are introduced. In particular, the physical interpretations of the DAMPE data are reviewed.
