The 14th Five-Year Plan period is a critical period for China to achieve high-quality development. Based on super-efficiency slacks-based measure(SBM) model, grey-related analysis(GRA) and other models, this paper studies the heterogeneity of the coupling relationship among technological innovation, industrial transformation and environmental efficiency in the Huaihai Economic Zone during the period of 2005-2019. In addition, it analyzes the coupling mechanism of single and binary systems to the ternary system, which is of great significance for the collaborative symbiosis among systems. The findings are as follows. 1) The technological innovation, industrial transformation and environmental efficiency(TIE) systems of the Huaihai Economic Zone had significant spatial-temporal heterogeneity. Although their evaluation value fluctuated, the development trends are all positive. Ultimately, technological innovation is characterized by being high in the northeast and low in the southwest around Xuzhou, while other systems are relatively staggered in space. 2) The coupling of TIE systems is in transition, lack of orderly integration and benign interaction. However, the developing trend of interaction is also upward, and a spatial pattern driven by Xuzhou and Linyi as the dual cores has gradually formed. Moreover, the coupling is mostly manifested as outdated technological innovation and industrial transformation. Except for the final coordination of regenerative cities, the other resource types are all in transition. Cities in all traffic locations are still in transition. The overall system interaction of cities on Longhai Line(Lanzhou-Lianyungang Railway) is relatively optimal, and cities on Xinshi Line(Xinxiang-Rizhao Railway) are accelerating toward synergy. 3) The coupling status of TIE systems depends on the development of the single system and the interaction of the binary(2E) system. The coupling is closely related to technological innovation and Technology-Industr

As representatives of high-precision parts， aerospace products are characterized by complex structures， long production cycles and high precision requirements. After the design of aerospace products is completed， a manufacturability assessment needs to be conducted based on 3D model features in terms of modeling quality and process design， otherwise the cost of design changes will be increased. Due to the poor structure and reusability of product manufacturing feature information and assessment knowledge in the current aerospace product manufacturability assessment process， it is difficult to realize automated manufacturability assessment. To address these issues， this paper first establishes a domain ontology model for aerospace product manufacturability assessment. On this basis， a structured representation method of manufacturability assessment knowledge and a knowledge graph data layer construction method are proposed. Based on the semantic information and association information expressed by the knowledge graph， a rule matching method based on subgraph matching is proposed to improve the precision and recall. Finally， applications and experiments based on the software platform verify the effectiveness of the proposed knowledge graph construction and rule matching method.

黄河源区是黄河流域最重要的水源地和产流区,贡献了超过全流域37%的产流量,对流域中下游地区的水资源安全、粮食生产和生态环境有决定性的意义。明晰黄河源区近60年来的气候水文和近30年来的植被覆盖特别是草地退化的变化特征,不仅是深入理解黄河源区水文循环机理的前提,也是准确把握源区及中下游水资源状况和生态环境的关键,更是贯彻习近平总书记“黄河流域生态保护和高质量发展”要求的核心问题。从气候角度看,黄河源区自1951年以来经历了显著的暖湿化过程,20世纪90年代有所回落。但从2000年以来,气温和降水以更快的速度增大,进而引发了冰川积雪消融加剧、蒸散发增加和冻土层退缩等一系列后果。然而,由于各个过程中水分损耗的加剧以及人类活动的影响,这种增湿并不能转换为有效的水资源,黄河源区的观测和天然河川径流量均呈现出减少的趋势。而不断退化的草地则使得区域水分涵养能力不断降低,生态环境不断恶化。面对黄河源区严峻的水资源和生态环境挑战,除了继续深入研究黄河源区水文循环机理外,建议应做到:(1)将生态环境保护放在首位;(2)水资源的有序开发利用;(3)社会生产与自然环境的和谐共存;(4)从战略高度贯彻实施有序适应气候变化。
