On Lonicera macranthoides varieties (lines) 'red bud 1', 'silver Cui Lei' and 'Cui Lei 109' flower buds and leaves of different maturity, the soluble sugar, protein, amino acid and Vc were analyzed. The results showed that the buds and leaves of 'red bud 1', 'silver Cui Lei' and 'Cui Lei 109' were rich in nutrients. The buds and leaves of 'Red bud 1' were rich in nutrients, and the contents of protein in the leaves of 'Cui Lei 109' and 'silver Cui Lei' were higher.

This work uses carbon emission pinch analysis (CEPA) method to analyze the energy mix of power generation in the Chinese power sector. It proposes to explore the optimal energy mix to achieve effective control of carbon emissions while meeting electricity demand. Under the constraint of global carbon neutrality, China's power industry is reducing carbon emissions by transforming the energy mix. The energy mix of China's power industry in 2030 and 2050 is analyzed according to the policy requirements and the emission reduction effect of the optimal combination. The study shows that vigorously reducing coal power, developing wind power and solar power as the main renewable energy sources, and vigorously developing the renovation and new construction of carbon capture and storage (CCS) technology for coal power are more conducive to reducing carbon emissions. The goals are up to achieve 4073.13 Mt CO 2 -e in 2030 and 3948.54 Mt CO 2 -e in 2050.

In order to coordinate the farmland transfer and the construction of the ecological environment, this paper first introduces the main work content and the main benefits of farmland transfer, and then separately elaborates the land leveling, farmland water conservancy, field roads and other projects in the process of farmland transfer. Value analysis of the impact on the ecological environment of farmland, and analysis of the problems existing in the value of farmland transfer: neglect of ecological environment protection, unreasonable arrangement planning and construction technology, lack of specific normative guidance for protecting the ecological environment during the arrangement process. The results of the study show that the evaluation of the ecological value of farmland can be used to guide the rational external transfer of farmland, which is beneficial to the protection of farmland. At the same time, it also has certain guiding significance for returning farmland to forests and lakes. Therefore, it is necessary to evaluate the ecological value of farmland.

According to the ISO 26262 standard, the fault injection test in the R&D verification stage can clearly show the stability or safety response ability of the Unit Under Test in the face of various faults or extreme conditions. This paper introduces the safety state mode of the motor drive system for electric vehicles, analyzes the possible fault forms of the Motor Controller Unit, builds a power hardware-in-the-loop test platform and carries out fault injection test by taking the motor rotation fault as an example. The results show that the fault injection test method proposed in this paper is an effective means to verify the functional safety of the electric drive system.

The fundamental purpose of green building design is to protect the environment, reduce pollution and save energy. Among them, energy-saving design is the most concerned one of green building. In this paper, the architectural design of Zhejiang Water Control Museum is selected as a case study, and the optimization design of energy conservation is carried out in the aspects of building orientation design, natural wind application, roof energy conservation design, renewable energy utilization and water resource utilization. This paper comprehensively monitors the energy consumption of the whole building by combining with the building intelligent management system, and dynamically displays the current energy saving effect, emission reduction sewage and sunshade effect. We hope to establish demonstration green buildings through this project research and strengthen the application and promotion of green building energy-saving technology.

Chestnut shell was selected as the raw material for extracting brown pigment, and the response surface methodology was utilized for optimizing the extraction conditions. In this paper, the effects of ethanol concentration, extraction temperature and time on the color value were studied and analysed by response surface experiments. The results showed that the quadratic regression model had ideal fitting effect to the experimental results. When the pH value of extraction system was 13, the optimum conditions for color value were consisted of an ethanol concentration of 28wt%, a reaction temperature of 83°C, and a reaction time of 2.3h. The extraction temperature had the greatest influence on the color value of the pigment. The interaction between ethanol concentration and extraction temperature had significant effects on the color value. And the interaction between ethanol concentration and extraction time had no significant effects. The color value of chestnut shell pigment can reach 31.25 ± 0.50 with the response surface optimization.
