The review summarizes the current state of research of two kinds of adhesives, i.e., synthetic adhesives and natural adhesives. Synthetic adhesives, consisting of urea-formaldehyde resins (UF), phenol-formaldehyde resins (PF), polyvinyl acetate emulsion (PVAc) and isocyanates, are widely used. For UF, most investigations are concerned with the reduction of free formaldehyde; for PF, most studies focus on finding new chemicals to replace phenol. PVAc has poor properties, but these can be improved by a blending reactions and copolymerization with other chemicals. Isocyanate is an environmentally friendly synthetic adhesive, but also suffers from inadequate properties. Natural adhesives, such as protein/starch, lignin and tannins, have poor bonding effect that limits their level of use, but their main advantages are that they are environmentally friendly and a renewable resource. Studies of modification can improve the bonding performances and gradually cause natural adhesives to become applied in industrial production. Some proposals for future development and the importance of environmentally friendly adhesives are provided, which will be helpful in future theoretical and experimental research.展开更多

Some steel ...Chinese steel industry has made significant progress on reducing fresh water consumption and CO_2/SO_2/COD( chemical oxygen demand) /dust emissions,and improving comprehensive utilization of solid waste. Some steel companies have become topped worldwide. However,due to the large output quantity of crude steel,the whole steel industry is still a huge source of pollutants. At present,environmental protection standards are encountering challenges of lack of technical support,taxation policy and other issues. Steel industry is currently facing enormous environmental pressure. The development trends of environmental protection technologies were studied by summarizing different development stages. To realize the development targets,the industry needs to carry out its research with independent intellectual property rights,develop comprehensive management systems and establish ecological chain with other industries. This can not only raise the level of environmental protection in a broader range,but also improve the energy efficiency of iron and steel plants and increase added value of waste utilization. Finally,23 environmental protection technologies were proposed and 4 new environmental protection practices were studied.展开更多

摘要We aim to present an overview of the status of adhesives in the wood industry, especially in the area of wood-based panels. The review summarizes the current state of research of two kinds of adhesives, i.e., synthetic adhesives and natural adhesives. Synthetic adhesives, consisting of urea-formaldehyde resins (UF), phenol-formaldehyde resins (PF), polyvinyl acetate emulsion (PVAc) and isocyanates, are widely used. For UF, most investigations are concerned with the reduction of free formaldehyde; for PF, most studies focus on finding new chemicals to replace phenol. PVAc has poor properties, but these can be improved by a blending reactions and copolymerization with other chemicals. Isocyanate is an environmentally friendly synthetic adhesive, but also suffers from inadequate properties. Natural adhesives, such as protein/starch, lignin and tannins, have poor bonding effect that limits their level of use, but their main advantages are that they are environmentally friendly and a renewable resource. Studies of modification can improve the bonding performances and gradually cause natural adhesives to become applied in industrial production. Some proposals for future development and the importance of environmentally friendly adhesives are provided, which will be helpful in future theoretical and experimental research.

摘要This study explores the application of deep learning(DL)to gravity research,which is a promising intersection of earth science and information science.DL provides new methods and ideas for exploring and solving problems related to multiple solutions and uncertainty in the study of gravity.We focus on the application of convolutional neural networks,recurrent neural networks,and other DL technologies to gravity data denoising,interpolation,anomaly inversion,field modelling,and geological interpretation.However,importantly,the application of DL to the field of gravity research is still in its initial stage.There is significant potential for development and widespread application in overcoming limitations in sample size,network framework optimization,and generalization ability.
摘要This article is focused on the analysis of the international cooperation of the Russian petroleum industry and its development trend. Also discussed here are the patterns that the foreign oil companies used in acquiring Russian petroleum assets, and the cooperation models of petroleum exploration and production in Russia. The Russian government encourages foreign oil companies to establish strategic alliances with domestic companies that keep good relations with the government. To achieve this goal, the government provides foreign companies with the space for cooperation in such aspects as advanced technology and management culture. International cooperation in petroleum industry will be further developed under the macro-control of the Russia State energy strategy. The energy cooperation between China and Russia will enter a new phase full of hopes and challenges after the past unfavorable situation is gradually overcome.
