数字孪生是实现智能制造和工业数字化转型的关键技术，受到工业界和学术界的广泛关注和研究。经过20年的发展，数字孪生的应用领域已经十分广泛。由于应用领域的多样性，针对数字孪生的组成部分提出了各种参考模型和研究方法。因此，本文对当前数字孪生基本组成部分的研究进行了系统研究。本文分析了2017年至2022年的117篇文章，通过理清数字孪生与信息物理系统的关系，首先明确了数字孪生的定义、特征和应用领域。在此基础上，分析了数字孪生核心组成部分（物理实体、虚拟模型、孪生数据）的研究方法。同时对数字孪生的应用领域进行了分析和圈定，探讨了数字孪生的应用潜力。最后提出了研究结果和未来的研究建议。
The digital twin is a crucial technology for realizing smart manufacturing and industrial digital transformation, which has received extensive attention and research from industry and academia. After 20 years of development, the application area of digital twins has been pervasive. Due to the diversity of application areas, various reference models and research methods have been presented for the components of the digital twin. Therefore, this paper provides systematic research of current studies on the basic components of the digital twin. This paper analyzed 117 articles from 2017 to 2022. By clarifying the relationship between the digital twin and the cyber-physical system, it first clarified the definition, characteristics, and application areas of the digital twin. On this basis, the research methodology of the core components of the digital twin (physical entities, virtual models, and twin data) is analyzed. At the same time, the application areas of digital twins are analyzed and delineated, and the application potential of the digital twin is explored. Finally, the research results and future research recommendations are presented.
