摘　　要：20世纪30年代天文学观测对标准宇宙模型提出了严峻挑战,为了调和观测数据与理论模型的矛盾,理论物理学家提出了暗物质理论;此后,实验物理学家据此摸索出了各种暗物质探测方案.本文将从暗物质概念的由来、暗物质基本性质、暗物质探测原理及方法和DAMPE在探测暗物质方面的最新进展几个方面展开介绍.重点以DAMPE的数据为基础,以电子谱分析为核心,在前人的研究基础上,对DAMPE数据和结果进行多层次、多方位的综合,进一步阐述了DAMPE电子谱中出现的TeV拐折和尖锐信号包含的深刻意义;最后依托研究过程中得到的一些信息,对未来暗物质探测实验提出一点看法和见解.In the 1930 s, astronomical observations presented severe challenges to the standard universe model. In order to reconcile the contradiction between observational data and theoretical models, theoretical physicists proposed dark matter theory. Since then, experimental physicists have explored various dark matter detection schemes. This paper introduces the origin of dark matter concept, the basic properties of dark matter, the principle and method of dark matter detection and the latest progress of DAMPE in detecting dark matter. The focus is on DAMPE data, with electronic spectrum analysis as the core, before based on human research, the multi-level and multi-directional synthesis of DAMPE data and results further elaborates the profound significance of Tev inflection and sharp signal in DAMPE electronic spectrum. Finally, relying on some information obtained during the research process, put forward some opinions and insights on future dark matter detection experiments.
