Fault diagnosis plays a significant role in conducting condition-based maintenance and health management for gas turbines(GTs) to improve reliability and reduce costs. Various diagnosis methods developed by modeling engine systems or certain components implement faults detection and diagnosis based on the measurement of systemic parameters deviations. However, these conventional model-based methods are hindered by limitations of inability to handle the nonlinear nature, measurement uncertainty, fault coupling and other implementing problems. Recently, the development of artificial intelligence algorithms has provided an effective solution to the above problems, triggering broad researches for data-driven fault diagnosis methods with better accuracy,dynamic performance, and universality. This paper presents a systematic review of recently proposed intelligent fault diagnosis methods for GT engines, according to the classification of shallow learning methods, deep learning methods and hybrid intelligent methods. Moreover, the principle of typical algorithms, the evolution of enhanced methods, and the assessment of pros and cons are summarized to conclude the present status and look forward to the future in the field of GT fault diagnosis. Possible directions for development in method validation, information fusion, and interpretability of intelligent diagnosis methods are concluded in the end to provide insightful concepts for scholars in related fields.

师范院校的兴起和民族国家现代教育体系的建立密切相关。在世界教育现代化过程中,师范教育具有举足轻重的地位。与世界其他国家相比,师范教育,尤其是师范大学独具中国特色。20世纪90年代以来,在由全球研究型大学主导的学术锦标赛体制下,我国师范大学的发展面临排名的威胁和强化科研导向的压力。在“双一流”建设背景下,为实现高质量发展,师范大学需要以一流为目标,在师范性和研究型之间保持平衡,并努力实现卓越教学和卓越科研的统一。在推进教育强国建设中,师范大学既要为基础教育培养优秀教师又要追求一流目标,还肩负着彰显中国大学模式并把中国教育文明的价值观传递给全世界的时代使命。

孙中山在《建国方略》中提出民权初步思想,主张训练民众开会以培养现代公民,进而实现“纠合群力”“发达民权”。借助学校和民众教育,南京国民政府以普及和演习议事规则为着力点,实践了民权初步思想。在学校,国民党注重传授学生系统的议事规则,训练其专业的议事技能。围绕选举权的行使,以识字为先导,国民党面向失学民众普及议事常识并训练其使用选举权。受观念束缚,受训后的民众议事能力与孙中山的设想仍有较大差距,这表明训练开会既要系统灌输议事规则,更要树立良好的会议氛围,以变迁议事观念,启蒙公民的权利、集体和规则意识。总结民权初步思想的实践教训对于新时代培养合格公民、发展社会主义民主政治具有一定鉴戒意义。
