    The green environmental protection industry has the dual attributes of driving economic growth and coping with environmental problems. The deep integration of “four chains” (i.e., innovation, industrial, capital, and talent chains) is crucial for the high-quality development of the green environmental protection industry and the achievement of the carbon peaking and carbon neutrality goals. Considering the development status of the green environmental protection industry, this study analyzes the characteristics of four-chain integration at different stages of enterprise development. In the early stage of establishment, the capital chain is key to enterprises and an industrial chain is gradually formed driven by the innovation and talent chains. During business expansion of enterprises, the industrial chain is extended, driven by the capital chain and supported by the innovation and talent chains. At the mature stage, enterprises can carry out strategic layout based on the industrial chain while maintaining the innovation chain. However, the four-chain integration in the green environmental protection industry of China still face several problems, including weak connection between the innovation and industrial chains, weak support of the capital chain to other chains, insufficient integration between the talent chain and the innovation and capital chains. To address this, we propose the following suggestions: (1) developing a low-carbon innovation strategy roadmap to clarify the development paths for four-chain integration; (2) improving the compatibility between the innovation and industrial chains; (3) optimizing the capital chain to improve its integration with other chains; (4) improving the talent chain; and (5) clarifying the driving chains according to the development stages of enterprises to ensure the effective integration of the “four chains”.

    China has considerable heavy oil reserves, with 60% being deep heavy oil. However, the mainstream thermal recovery technologies, such as cyclic steam stimulation, have a recovery rate of less than 20%. The development potential of heavy oil resources is enormous, and actively exploring new development methods to improve the recovery rate is an inevitable choice for the high-quality development of the petroleum industry. This study focuses on the construction of a chemical compound flooding technology system for heavy oil and its field application, providing an effective solution for the development of green and low-cost sequential technologies for deep heavy oil. Based on the analysis of the components of heavy oil, this study elaborates on the structural viscous mechanism and the recovery improving mechanisms (i.e., chemical viscosity reduction, starting pressure gradient reduction, and oil displacement efficiency improvement mechanisms), which enriches the theoretical understanding. In response to urgent need of engineering applications, this study breaks through the green chemical flooding system for heavy oil from two aspects: the design and synthesis of water-soluble viscosity reducers and the development of self-assembling plugging agents.

    Intelligent manufacturing is a systematic engineering and technological innovation that propels the transformation and upgrading of China’s manufacturing industry, enhancing industrial competitiveness. It is a pivotal element in strengthening the manufacturing sector of China. The comprehensive and profound advancement of intelligent manufacturing necessitates adherence to ideological innovation, requiring the formulation of a scientifically grounded development strategy from its philosophical roots. This paper, based on the phenomenological reductionism and ontological perspective method, starts from the perspective of the philosophy of technology, integrates systemic dialectical logical reasoning, investigates and identifies the “hard problems” of human–machine collaborative technology in intelligent manufacturing, and insightfully explores its philosophical essence from the standpoint of the philosophy of scientific epistemology. The research findings indicate that explicit knowledge and tacit knowledge are commonly present in manufacturing technology activities. However, the long-standing technological development has overlooked the significance of tacit knowledge and has made an unreasonable assumption about the existence of “rational people” in human subjects, neglecting their crucial role in manufacturing systems. Therefore, this paper, through ontological reflection, proposes a Cartesian intelligent manufacturing technology development path based on the Internet of Things, Internet of Contents & Knowledge, and Internet of Bodies. Building upon this foundation, it establishes a Heideggerian intelligent manufacturing system architecture grounded in behavior-oriented, deictic representations, and embodied embedding. Through this traceable causal analysis, it constructs a three-stage progressive development knowledge paradigm for resolving the “hard problems” of human – machine collaborative technology. This paradigm is characterized by data-driven, functional representation, and embodied integration. To efficiently promote the development of the new-generation intelligent manufacturing, a knowledge engineering classification assessment system can be established. The application of theoretical cognitive models can drive the resolution of technological challenges and the formulation of industry support policies. Establishing a multi-faceted application-oriented intelligent manufacturing public service platform strengthens knowledge circulation and integrated application.

    Space assets are crucial resources for a nation, and effectively managing the various risks associated with them will help maximize their benefits, enhance their contribution to national modernization and security, and improve the strength of the space industry. First, this study clarifies the definition and scope of space assets. In a narrow sense, space assets encompass all spacecraft in orbit. Broadly speaking, space assets also comprise related physical and intangible assets. Second, potential risk sources are identified from multiple dimensions and categorized into technical risks (such as collision disintegration, explosive disintegration, and load failure), military risks (including the use of spacecraft as weapons or weapon platforms), and management risks (referring mainly to mismatches in management systems, leading to loss of intangible assets). Subsequently, this study explores a quantitative assessment method for the technical risks, establishes a model for quantifying space asset values, and briefly analyzes possible risk control methods. Furthermore, a preliminary classification model for risk events is proposed along with several considerations including establishment of systems and mechanisms, formulation of response plans, responsibility allocation, and implementation and supervision of disposal actions.

    Pinglu Canal is the backbone project of the New Western Land-Sea Corridor of China. The canal project generated a total of 3.39 × 108 m3 of earthwork that covers approximately 23 types of rocks and soil and is characterized by large amount, diverse composition, and scattered distribution. Currently, the earthwork is utilized mainly through landfill and reclamation (over 50%); however, basic problems exist, including a low high-quality utilization rate, lagging research on demand for earthwork-reused products, lack of innovative technologies for earthwork reuse, a low level of digitalization, and lack of carbon emission evaluation. To address these problems, this study proposes innovative solutions from the perspectives of resource utilization, digitization, and carbon reduction. First, it is necessary to explore the potential application demands for the canal project itself and surrounding areas and propose corresponding utilization paths according to different types of rock and soil, thus to achieve multi-scenario, multi-path utilization. Second, geological information models and information databases should be established for earthwork in excavation areas to help develop a digital excavation-transportation-storage-utilization technology for earthwork. Moreover, it is recommended to conduct a lifecycle assessment to clarify the carbon emissions of multi-path utilization technologies, achieve a dynamic evaluation of carbon emissions by combining with the information from the earthwork databases, and develop modular mobile-type disposal equipment and in-situ utilization technologies to achieve the reduction of cost and carbon emissions. The organic combination of resource utilization, digitization, and carbon reduction is expected to provide a favorable support for the green construction of the Pinglu Canal Project.
