After analyzing the ambient air quality data from 2020 to 2021 by SPSS26.0, the results show that the top five districts in the comprehensive score of ambient air quality are Fangzheng County, Bin County, Tonghe County, Wuchang City, and Mulan County. The last five districts are Nangang District, Xiangfang District, Daoli District, Daowai District, and Pingfang district. This method gives weight to the evaluation indicators to make the indicators with more significant impact factors play a more prominent role in the evaluation. Moreover, it removes redundant information in the indicators and makes the assessment results more scientific and reasonable. Significantly, the research can also be extended to the ranking evaluation of various environmental elements, providing a new idea for formulating assessment and evaluation policies of ecological environment quality.","PeriodicalId":120565,"journal":{"name":"2022 International Conference on Environmental Science and Green Energy (ICESGE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129066510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The temperature curve was then measured under various intake pressure and flow conditions, as well as after adding heat exchange fins, to determine the distribution trend and rule of the reactor's temperature field. The experimental results show that when hydrogen is charged at a constant intake pressure, the reactor's internal temperature rises rapidly, and the upper and lower bed temperature rises uniformly. When the intake pressure increases continuously, the maximum temperature of the inner and outer walls of the reactor becomes higher, and the hydrogenation reaction time is shorter. When hydrogen is charged at a constant intake rate, the temperature rise of the whole reactor is more stable, and the time for the bed to rise to the maximum temperature is longer. Still, the maximum temperature of the bed is lower than that of the full-flow hydrogen supply mode. Heat transfer fins can improve the heat transfer performance of the reactor, reduce the maximum temperature reached by the bed, and timely conduct excess heat in the reactor to the outer wall.","PeriodicalId":120565,"journal":{"name":"2022 International Conference on Environmental Science and Green Energy (ICESGE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115029869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, the synthesis mechanism of YBCO superconducting phase and the kinetic parameters were obtained using the universal differential, integral and multi-rate scanning Kissinger methods. The results showed that the thermal decomposition was divided into four stages characterized by weight loss from 25°C to 900°C. The fourth stage for the synthesis reaction of YBCO phase follows the random nucleation and subsequent growth (n = 2) model; the activation energy and pre-exponential factor of the fourth stage were 222 kJ/mol and $2.34 times 10^{10}/min$, respectively. In terms of reaction mechanism and kinetic parameters, the kinetic equation expressing the formation process of YBCO superconducting phase was obtained.","PeriodicalId":120565,"journal":{"name":"2022 International Conference on Environmental Science and Green Energy (ICESGE)","volume":"10 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113968309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the full three-dimensional model of the shaft system of a 1000 MW hydro-generator unit is established to accurately analyze the structural behavior of the shaft system via the finite element method with different boundary conditions. The analysis results show that the installation deviation increases the oil film thickness of the hydraulic bearings and greatly reduces the bearing stiffness of the hydro-generator shaft system. Since the bearings are the most important boundary conditions of the shaft system, the reduction of the bearing stiffness due to installation deviation is 1/10 of the designed bearing stiffness, which significantly changes the eigenmodes and eigenfrequencies of the hydro-generator shaft system. The first eigenfrequency of the hydro-generator shaft system with installation deviations is around 68.8% of the eigenfrequency without installation deviations. The installation deviations negatively affect the safe operation of hydro-generator units. Therefore, it is extremely important to control the shaft system installation deviation with high precision to ensure the stable operation of hydro generator units.","PeriodicalId":120565,"journal":{"name":"2022 International Conference on Environmental Science and Green Energy (ICESGE)","volume":"398 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124749225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, three uranium isotopes produced and accumulated in the reactor may present problems in RepU recycling. They are ${}^{232}mathbf{U}$, whose daughter products are $beta$ and $gamma$ rays emitters, ${}^{234}mathbf{U}$ as $boldsymbol{alpha}$ rays emitters, and ${}^{236}mathbf{U}$ as neutron absorbers, respectively. These nuclides put forward higher radiation protection requirements for the facilities and equipment in the RepU recycling process. By combining the nuclides characteristics of RepU and uranium processing procedures, and experiences learned from advanced countries that are experienced and specialized in utilizing RepU,this paper summarizes the special requirements for RepU recycling. Furthermore, it suggests the main processes during RepU recycling, including uranium conversion, enrichment, and fuel assembly fabrication from a radiation protection standpoint, which promotes RepU recycling in China and reduces ionizing hazards to an acceptable level.","PeriodicalId":120565,"journal":{"name":"2022 International Conference on Environmental Science and Green Energy (ICESGE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128499878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Variation of TEC is closely related to solar activity and geomagnetic activity, so data sets for this article are created based on 2019–2020 TEC map data, as well as the hourly solar radiation index F107 and geomagnetic index Kp together with the corresponding time, and longitude and latitude of each parameter are introduced as supervision information. The long short-term memory (LSTM) network and the multilayer perceptron (MLP) in the deep learning method are used to build a 9-layer deep neural network for training and verification, so that the advantages of the “gate” mechanism of LSTM network in time series modeling and the advantages of MLP in comprehensive consideration and high reliability can be fully brought into play. 70% of data sets are divided into training sets and 30% for validation, which runs in CPU environment.
