Based on Standard Literature Library of CNKI, opportunities for technical standards development are identified. The initial keywords of technical standard are determined based on LDA model, whose similar keywords are further confirmed by Word2Vec, and then combining LDA model with Word2Vec the representative keywords of technical standard of manufacturing industry are determined. According to confirmed representative keywords, the core technical standards of manufacturing industry are identified by using the center degree and “M-core” method. The dimensions of the frequency square matrix are reduced by using the PCA module of Python, and the scatter plot is brawn, the technology gaps are identified by combing the consideration on the core technical standards, and then the future development opportunities are confirmed based on the map of patent technology effect matrix.

Based on house of quality concept, the relation between servitization strategy and strategic elements were confirmed through grey relational analysis method. Accordingly, the specific elements characteristics of manufacturing enterprise management core - talents & team and relationship, knowledge resources and flowing, information infrastructure and treatment methods, and organization structure and management were illustrated in three servitization stages - product servitization enlarging, servitization capability continuously improving and servitization integration and innovation. According to elements characteristics, the strategic targets for different servitization stages were brought forward, and four strategic elements specific managing methods were further offered for different servitization stages. The research can offer decision references for manufacturing enterprise to confirm element character and servitization stage, and give effective support to confirm management key points and methods of servitization in manufacturing enterprises at different stages.

Making full use of network member resources to improve performance has become a strategic choice for manufacturing enterprises. Based on the analysis of member relationship dimensions and manufacture enterprise network types, the influences among member relationship dimensions and their influences on network performance are discussed. The weighting indexes and standards are designed, and structural equation method is used to test the hypothesis. The following results can be obtained: member relationship dimension self-accelerating effects commonly exit, and “the communication’s influence on trust” has become the key for member relation optimization. Trust is important for all networks cooperation. The contract, trust and communication individually become the management key or efficiency, innovation and flexibility manufacturing network.

With the development of the offshore oil and gas fields, more and more offshore oil and gas fields are found to have high carbon dioxide. In addition, as peaking carbon dioxide emissions and carbon neutrality were written into the government work report for the first time, the correct separation and emission of CO2 have become a key issue that needs to be solved by offshore oil and gas fields. In this paper, we studied two CO2 separation methods suitable for offshore platforms and the current status of CO2 offshore storage and application. Moreover, the development of offshore carbon dioxide storage application was investigated in detail, and the technical characteristics and application prospects of CO2-EOR and CO2 replacing combustible ice were analysed and discussed. This paper analyses the challenges and countermeasures of offshore CO2 storage from many aspects. It provides a theoretical reference for future CO2 treatment in offshore oil and gas fields.

This paper briefly summarizes that during the depressurization operation in subsea pipeline for maintenance or prevention of hydrate formation, because the flare knock-out drum pump is designed for ambient temperature, and cannot deal with the low temperature fluid in the depressurization process. Therefore, the low temperature fluid needs to be heated in the knock-out drum to meet the temperature requirement of pump. In order to avoid the volume of low temperature fluid exceeding the surge volume of the flare knock-out drum, the concept of multi stage depressurization is innovatively proposed in this paper, which meets both the requirements of pump temperature and the surge volume of flare drum. Taking a gas field project in the South China Sea as an example, the simulation analysis of depressurization temperature and pressure is carried out by using different size of the blowdown valve. It provides a good reference for the similar project in future.

Smart government is the advanced stage of e-government development, whose essence is the fusion of Internet, Internet of things, cloud computing, big data and other high and new technology and e-government, to achieve the efficient management of all kinds of information resources and make the government services more transparent, scientific and wisdom. Based on the introduce, basic principle and construct meaning, application system construction, main problems and developing countermeasures and other aspects of smart government to make a comprehensive analysis in the construction of Zhengdong new district smart government, then advise the government departments to speed up the transformation of government management functions and social service mode to integrate the business processes, and promote the construction of service-oriented and smart-oriented government actively.
