During the development of pre-made and conditioned foods, the corresponding recipes and process requirements should be met, large-scale production work should be performed in the central kitchen, and then distributed to the terminal stores, so that the conditioned foods become more popular. Based on previous work experience, this paper summarizes the research status of key technologies for preserving and sterilizing pre-processed foods. At the same time, this article discusses the key technical application content of pre-conditioned food processing quality and sterilization from four aspects: the application of ultra-high pressure technology, the prevention and control of common microorganisms, the application of tea polyphenols, and the development trend of pre-conditioned food.

In recent years, following with the development trend of large-scale and complexity in engineering, project management has been more and more difficult, both in China and abroad. Virtual Construction Mode (VCM), the modification and optimization of traditional project management mode, meets the needs for the current large-scale engineering management. With the strong support of Virtual Organization (VO) and Vitrual Technology (VT), VCM has the capacity to promote multi-party coordination, resource conservation, as well as scheme prioritization and so on.

With the rapid growth of international container transportation and the development trend of large-scale ships, there are deficiencies in ship utilization and transportation economy. More and more liner companies are actively building and optimizing container shipping network to improve service efficiency and reduce unit operating cost. The optimization model of container shipping network is established. Taking the minimum total cost of container shipping network as the objective, considering the constraints of shipping network, the immune algorithm is applied to solve the model, to determine the optimal container transportation network. Finally, two schemes are designed, and the simulation analysis results can select an optimal scheme, and the effectiveness of the proposed method is verified.

At present, development of ground-coupled heat pump technology in China has entered the stage of large-scale project application from purely theoretical stage. The key question is how to apply theory to practice efficiently. However, there are still a large number of scholars who remain in the Researches on theoretical heat transfer of buried tube heat exchanger and theoretical soil thermal equilibrium. So it is essential to know the status of ground-coupled heat pump, the pressing issues and trends in the development process. This paper revealed the development status of ground-coupled heat pump, analyzed problems combining with engineering examples and predicted the development trend reasonably. The important issues are mass demonstration and promotion, which need reasonable solutions and proven technology.

China’s mine enterprises have gradually advanced towards the direction of collectivize and large-scale development, which requires continuous improvement and innovation on safety management. Based on the actual situation of safety management in China’s mine enterprises, this paper gave a general analysis of three principles in mine enterprises as material-oriented safety management, humanistic safety management and heart-oriented safety management and their adaptation in practice, as well as their limitations, and at last, it put forward a scientific implementation method. In addition, this paper discussed a model of Tri-intrinsic safety management which integrates three ideological principals of material-oriented safety management, humanistic safety management and heart-oriented safety management into mine enterprises. Based on Marxism theory on law of social and human development, Tri-intrinsic safety management is devoted to achieve the unification of safety values of employees and enterprises, the unification of people’s health and safety, as well as ego-development and production efficiency. Meanwhile, this model complied with the development trend of safety management in China’s mine enterprises, which can promote safety management of mine enterprises to a new level of development.

Since the early 2000s, the vegetation cover of the Loess Plateau (LP) has increased significantly, which has been fully recorded. However, the effects on relevant eco-hydrological processes are still unclear. Here, we made an investigation on the changes of actual evapotranspiration (ETa) during 2000–2018 and connected them with vegetation greening and climate change in the LP, based on the remote sensing data with correlation and attribution analysis. Results identified that the average annual ETa on the LP exhibited an obvious increasing trend with the value of 9.11 mm yr−1, and the annual ETa trend was dominated by the changes of ETa in the third quarter (July, August, and September). The future trend of ETa was predicted by the Hurst exponent. Partial correlation analysis indicated that annual ETa variations in 87.8% regions of the LP were controlled by vegetation greening. Multiple regression analysis suggested that the relative contributions of potential evapotranspiration (ETp), precipitation, and normalized difference vegetation index (NDVI), to the trend of ETa were 5.7%, −26.3%, and 61.4%, separately. Vegetation greening has a close relationship with the Grain for Green (GFG) project and acts as an essential driver for the long-term development trend of water consumption on the LP. In this research, the potential conflicts of water demanding between the natural ecosystem and social-economic system in the LP were highlighted, which were caused by the fast vegetation expansion.
