The optimized variational modal decomposition (VMD) algorithm is widely used in the diagnosis of rolling bearing faults. However, the subjectivity of the optimization range can compromise the effect of fault feature extraction under strong background noise (SBN). To enhance the fault diagnosis accuracy of rolling bearings under SBN, an adaptive range selection for parameter optimization of the VMD algorithm was developed. The proposed algorithm utilizes a method based on peak spectral clustering and center frequency to determine the optimal range of mode number and penalty factor. An optimization process based on the weighted kurtosis spectrum L 2 /L 1 norm is then employed as the fitness function to obtain the optimal values of modes and penalty factor. Experimental results have demonstrated that the proposed method achieves a 20.02 % increase in fault diagnosis accuracy compared to the classical adaptive variational mode decomposition (AVMD) method.

本文立足于新时代背景下外语教材建设的内涵,聚焦高校韩语教材建设的具体路径,围绕课程思政,新文科建设,数字化转型三个方面探讨高校韩语教材建设如何完成外语教材肩负的时代使命:第一,如何将中华文化有机融入高校韩语教材;第二,高校韩语教材建设如何适应跨学科要求,实现学科间的交叉融合;第三,如何建设高校韩语数字化教材。通过对这些问题的探讨,期望能为新时代外语教材建设的相关学术研究及实践探索提供借鉴和启示。 This article is based on the connotation of foreign language teaching material construction in the context of the new era, focuses on the specific path of Korean language textbook construction in colleges and universities, and explores how the construction of Korean language textbook in colleges and universities can fulfill the mission of the times shouldered by foreign language teaching materials from three aspects: curriculum ideology and politics, new liberal arts construction, and digital transformation: First, how to organically integrate Chinese culture into Korean language textbooks in colleges and universities; second, how to build Korean language textbooks in colleges and universities to adapt to interdisciplinary requirements and achieve cross-integration between disciplines; and third, how to build digital Korean language textbooks in colleges and universities. Through the discussion of these issues, we hope to provide reference and inspiration for related academic research and practical exploration of foreign language teaching material construction in the new era.

在国家大力推进一流本科教育的背景下,做强一流专业、培养一流人才已经在高校形成广泛共识,一流本科专业建设成为了高校加快推进教育教学改革、实现内涵式发展的重中之重。本文立足外语类专业自身发展特点,围绕落实新文科建设要求,拟从时代背景、人才培养、学科建设、资源支持这几方面剖析当前外语类一流本科专业建设过程中所面临的困境,并探索突破这些困境的有效方法,以期为外语类一流专业建设提供启示和参考。 In the context of the country’s vigorous promotion of first-class undergraduate education, strengthening first-class majors and cultivating first -class talents have formed a wide consensus in colleges and universities. First-class undergraduate majors have become the top priority of accelerating education and teaching reform and realizing connotative development. This article is based on the characteristics of the development of foreign language majors, focusing on implementing the requirements of new liberal arts construction, and intended to analyze the dilemma faced in the current first-class undergraduate majors in foreign languages from the background of the times, talent training, discipline construction, and resource support, and explore breakthroughs in breakthroughs The effective methods of these dilemma are in order to provide inspiration and reference for first -class professional construction of foreign language.
