Urbanization is a potential factor in economic development, which is a main route to social development. As the scale of urbanization expands, the quality of the urban water environment may deteriorate, which can have a negative impact on sustainable urbanization. Therefore, a comprehensive understanding of the functions of the urban water environment is necessary, including its security, resources, ecology, landscape, culture, and economy. Furthermore, a deep analysis is required of the theoretical basis of the urban water environment, which is associated with geographical location, landscape ecology, and a low-carbon economy. In this paper, we expound the main principles for constructing a system for the urban water environment (including sustainable development, ecological priority, and regional differences), and suggest the content of an urban water environmental system. Such a system contains a natural water environment, an economic water environment, and a social water environment. The natural water environment is the base, an effective economic water environment is the focus, and a healthy social water environment is the essence of such a system. The construction of an urban water environment should rely on a comprehensive security system, complete scientific theory, and advanced technology.

The concept and technologies of computing-network integration are still in the early stage of development. Research on computing task scheduling and network interconnection are still inadequate. Therefore, it is urgent to understand the developmental trend of the intelligent connection computing network technology (ICCNT) and propose a strategic conception and development routes for the independent innovation of ICCNT in China. This study analyzes the major challenges faced by the existing information network technologies and summarizes the developmental trends of computing-network integration. It also proposes a core architecture of the ICCNT and clarifies its development goals and expected performance. The development path of ICCNT is explored, covering key technologies such as diversified protocol support, integrated control of network, storage, and computing, intelligent arrangement of service functions, and endogenous security structure, as well as demonstration applications in the smart park network, vertical industry network, and data center network scenarios. Furthermore, we suggest innovating ICCNT systems, expanding the demonstration applications of ICCNT, and accelerating the implementation of ICCNT products, thereby promoting the evolution and application of ICCNT.

Oil-bearing materials are the main source of vegetable oils and proteins. Some fatty acids and certain structured lipids have particular biological functionality. Important progress has been made in this respect in recent years. Certain amount of socalled wastes are produced simultaneously along with the vegatable oils and proteins production, which have not been utilized perfectly for a long time. Actually, many value-added prod-ucts can be isolated from the “wastes”，such as lecithin, tocopherols, tocotrienols, plant sterols and stanols, isoflavones, saponins, phytic acids, trypsin, oligsaccharides, phenolic acids, etc. Then are considered to be functional components. Due to the particularity of the functional components, current technology and equipments of oil industry are not totally adaptable to the requirement of their isolation. Thus, the innovations of fats and oils technology as well as the utilization of biotechnology in making structured lipids are of great significance .

The strategic oil reserve is very important for every large country in the world. In order to meet the basic requirement of the state safety, 3 months strategic oil reserve in every large country was proposed by the different international organizations such as UN, EU, etc. For China, the total amount of strategic oil reserve must be up to about 30 to 90 millions. It is very difficult to achieve it without enormous capita in short time. Based on a new conception as "function reserve" to replenish the "resource reserve", this goal could be more easy to be accomplished.Namely, storing more methanols replaces some percentage of oil. Moreover, the state safety should be ensured. This topic is discussed in the article in detail.

Multifunctional structures (MFSs) integrate diverse functions to achieve superior properties. However, conventional design and manufacturing methods—which generally lack quality control and largely depend on complex equipment with multiple stations to achieve the integration of distinct materials and devices—are unable to satisfy the requirements of MFS applications in emerging industries such as aerospace engineering. Motivated by the concept of design for manufacturing, we adopt a layer regulation method with an established optimization model to design typical MFSs with load-bearing, electric, heat-conduction, and radiation-shielding functions. A high-temperature in situ additive manufacturing (AM) technology is developed to print various metallic wires or carbon fiber-reinforced high-meltingpoint polyetheretherketone (PEEK) composites. It is found that the MFS, despite its low mass, exceeds the stiffness of the PEEK substrate by 21.5%. The embedded electrics remain functional after the elastic deformation stage. Compared with those of the PEEK substrate, the equivalent thermal conductivity of the MFS beneath the central heat source area is enhanced by 568.0%, and the radiation shielding is improved by 27.9%. Moreover, a satellite prototype with diverse MFSs is rapidly constructed as an illustration. This work provides a systematic approach for high-performance design and advanced manufacturing, which exhibits considerable prospects for both the function expansion and performance enhancement of industrial equipment.

Concrete is a continuously evolving material, and even the definition of high-performance concrete has changed over time. In this paper, high-performance characteristics of concrete material are considered to be those that support the desirable durability, resilience, and sustainability of civil infrastructure that directly impact our quality of life. It is proposed that high-performance material characteristics include tensile ductility, autogenous crack-width control, and material “greenness.” Furthermore, smart functionalities should be aimed at enhancing infrastructure durability, resilience, and sustainability by responding to changes in the surrounding environment of the structure in order to perform desirable functions, thus causing the material to behave in a manner more akin to certain biological materials. Based on recent advances in engineered cementitious composites (ECC), this paper suggests that concrete embodying such high-performance characteristics and smart multifunctionalities can be designed, and holds the potential to fulfill the expected civil infrastructure needs of the 21st century. Highlights of relevant properties of ECC are provided, and directions for necessary future research are indicated.

Research and development trends of electrodeposited multifunctional composite materials are reviewed at home and abroad, including polybasic composite electrodeposition, pulse composite electrodeposition, pulse jet electrodeposition, electrodeposition of nano-powders and functional gradient materials. Results show that wear resistance, corrosion resistance and anti-high temperature oxidation of these kinds of composite coatings are much better than those of tranditional single metal coatings, alloy coatings and their composite coatings. They will have wide application prospects in the future.
