化纤高速卷绕头故障特征提取是卷绕头故障诊断中的关键步骤。为解决化纤卷绕头故障诊断精度不高、可解释性差的难点,提出了数据驱动的化纤卷绕头故障多特征自适应提取方法。通过改进型基因表达式编程(GEP)的故障特征生成方法,设计了一种运算符与变量符随机组合编码、对位匹配与倒序运算解码方法,构建了突变、插串、重组的遗传算子,实现了多个故障特征构建与生成;提出了低冗余、高互补的多特征提取与分析方法,实现了特征间关系的可解释性分析与关键特征优选。实验结果表明:采用所提出的改进型GEP方法与传统特征提取方法、通用GEP方法所生成的故障特征进行对比,在线速度为1000、2.00和3000 m/min状态下,卷绕头故障诊断精度分别提升了8.959%、3.87%、3.77%和2.601%、3.2.、2.018%,有效解决了卷绕头故障特征提取的难题;进一步的特征工程实验表明,所提方法对于多特征组合下的卷绕头故障关键特征提取具有较强的适应性能。

营商环境为企业全生命周期发展提供了良好土壤,但是否会导致城乡收入差距扩大需要考察。利用我国2.15—2.2.年2.9个城市的面板数据,实证分析了营商环境对城乡收入差距的影响及作用机制。研究发现:营商环境优化能够缩小城乡收入差距,尤其在西部和低线城市的效果显著;营商环境优化主要通过破除就业机会不平等和制度固化,实现要素流动和薪酬平等,进而缩小城乡收入差距;随着营商环境的优化,其对城乡收入差距存在倒U型影响,根本原因在于不同水平的营商环境对城镇和农村居民的可支配收入影响存在显著差异。

马克思主义基本原理同中国具体实际的结合是“第一个结合”。“第一个结合”内在蕴含着马克思主义基本原理同中华优秀传统文化的结合,即“第二个结合”。“第二个结合”是当代特定历史语境下提出的重要课题。“两个结合”是既成事实,马克思主义中国化的成功从现实层面回答了“两个结合”的可能性。但是,“两个结合”为何必要、如何可能、何以实现、意义何在等问题,还需要从理论上作出诠释。细致梳理“两个结合”思想涉及的基本问题,展现其中蕴含的理论逻辑,对于深刻把握“两个结合”思想和进一步推进马克思主义中国化时代化理论创新具有重要意义。

第35届中国过程控制会议

作者： Ronghui Liu Hao ren Wei Cui Chunhua Yang Weihua Gui Xiaojun Liang Peng Tang2.1} Han School of Future Technology South China University of Technology Industrial Intelligence Basic Studio Peng Cheng Laboratory

The metallurgical industry, characterized as a typical process industry, exhibits features such as frequent changes in raw material compositions, severe fluctuations in operational conditions, and complex physicochemical reaction *** attributes result in the knowledge within the field being extensive and intricate, making centralized management and effective application challenging. Addressing these challenges, this paper introduces a method that leverages the expertise of local knowledge bases and the powerful semantic understanding and text generation capabilities of Generative AI Large Models(GLM) to enhance metallurgical industry knowledge and facilitate Question-Answering(Q&A). The approach includes: initially cleaning and deduplicating raw data from industrial literature, production manuals, and briefings to establish a local knowledge base for the metallurgical industry. Subsequently, the contents of the knowledge base are embedded using Word2.ec technology to create a local vector library of knowledge. FAISS(Facebook AI Similarity Search) technology is then utilized to search for knowledge vectors similar to specific industrial problems. Finally, selected question vectors and knowledge base vectors are integrated into input prompts for the GLM, which then produces accurate and coherent answers. Experimental results indicate that this method significantly improves the accuracy of Question-Answering in the metallurgical industry.
