Abstract: Advanced technology talents are the key to achieve the goal of revitalizing the nation through science and education and talents. Based on the definition of academic chain connotation, using the comparative research method and interview method, we analyze senior talents cluster growth phenomena of the Quaternary loess research groups, glaciology research groups and “two bombs and one satellite” research groups, then analyze their internal academic inheritance and development. Senior talents in the development of clusters of academic chain phenomenon include three basic forms, namely horizontal type, vertical type and comprehensive type. Complementary and sharing mechanism of knowledge, disciplinary integration and combination mechanism, the drive mechanism of the country and the needs of society, team collaboration and stimulation and innovation mechanism, personal interests’ leading and the teacher pointing mechanism are the internal mechanism of the formation of the above three types of academic chain.

摘要： 高级科技人才是实现科教兴国和人才强国的关键。在界定学术链内涵基础上，采用对比研究法和调查访问法，对我国第四纪黄土研究群体、冰川冻土研究群体、“两弹一星”研究群体中高级人才集群成长现象进行了梳理，剖析了其内部学术思想的传承和发展轨迹。高级科技人才集群成长中的学术链现象包括三种基本形态，即横向式、纵向式和综合式。知识的互补和共享机制、学科的集成与整合机制、国家及社会需求的驱动机制、团队协同和激励创新机制、个人兴趣引领和名师指点的诱导机制是上述三类学术链形成的内在机理。
