Training high-quality talents needs to take curriculum as the basic way. Curriculum is the design and planning of education. The training objectives of the school must be achieved through specific courses. The educational policy can be implemented only through specific courses. Teaching activities can be realized only by relying on the curriculum plan. The teaching content can be transformed into students’ quality and ability through courses. It can be seen that curriculum is the basic way to implement quality education. As a new educational concept, quality education can be implemented in the whole educational process only when it is internalized into the curriculum and the thoughts of educators. However, with the rapid development of modern science and technology and the establishment of the idea of quality education, the setting of the original curriculum system in China’s universities of science and technology has exposed many disadvantages that do not adapt to the development of modern society. Based on this, on the basis of deepening the theoretical research on curriculum, this paper deeply discusses the achievements and existing problems of humanistic quality curriculum in China’s universities of science and technology, and then puts forward a set of countermeasures and suggestions for humanistic quality curriculum in Universities of science and technology suitable for China’s national conditions.","PeriodicalId":360004,"journal":{"name":"2021 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"263 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132426711","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}

This paper uses 20, 000 TCM text collected from the Chinese medicine clinic of the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine from 2005 to 2020 as the data set, data set source URL: http://www.sdmlzy.com. By labeling the four-word position of the characters in the text of TCM text, the word2vec is applied, by using the Long Short-Term Memory (LSTM) variant bidirectional gate recurring unit Gated Recurrent Unit (GRU) and then using Viterbi algorithm to achieve the resolution of TCM text word segmentation.

Different supporting parameters such as curvature radius of vertical temporary support, steel arch spacing and shotcrete thickness are selected for simulation study. The result of research shows that, based on the background project, the supporting effect of vertical temporary support is relatively good when the radius of curvature is between 23m and 29m. The displacement and stress of surrounding rock will increase with the increase of steel arch spacing, and the recommended value is between 0.5 m and 1.0m. The increase of shotcrete thickness is conducive to controlling the deformation and improving the stress state of surrounding rock. However, the effect is not obvious when the thickness exceeds 40cm, so it is recommended that the thickness should not exceed 40cm.","PeriodicalId":360004,"journal":{"name":"2021 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114438308","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 average daily domestic waste produced in big cities like Beijing, Shanghai, and Guangzhou has exceeded 20,000 tons. In the past, the incineration performance of waste incineration plants received little attention, but now the situation has changed completely. Waste combustion includes four processes: drying, devolatilization, gasification, and coke combustion. In the waste incinerator, the grate can thoroughly stir the waste through the reciprocating motion to make the waste fully contact with the air, which is conducive to the combustion of waste. With the rapid popularization of MSW incinerator and the speedy development of incinerator technology, the numerical simulation technology of MSW incinerator has attracted unprecedented attention. In order to describe the combustion process of waste on the grate in detail, Yang et al. establish the mass, momentum, and heat transfer control equations of solid and gas phases of the moving bed of MSW incinerator, and present the corresponding sub-models. Yang et al. develop the two-dimensional bed combustion simulation software FLIC, which combines with various sub-models to solve the control equations of solid and gas phases. Due to the channeling effect in the process of bed combustion, the mathematical modeling becomes very complex, so the FLIC software does not consider the channeling effect, and the calculation results of the software are in good agreement with the experimental results. Based on the FLIC software, Yang et al. develop the FLIC-FLUENT combined simulation technology of the MSW incinerator, which can simultaneously simulate the bed combustion on the grate and the airflow field above the bed, and simulate the influence of various design and operation parameters on the performance of the incinerator. The calculation results of the FLIC-FLUENT combined simulation technology are in satisfying agreement with the experimental results. This technology provides adequate reference data for the design and optimization of large-scale MSW incinerator.","PeriodicalId":360004,"journal":{"name":"2021 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116344383","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 visual interface, building block programming, and easy-to-use features of Scratch are suitable for teaching elementary school students, which can also better cultivate students’ analytical problem-solving skills and enhance their logical thinking. However, only a part of schools and students are currently learning this programming, and it is not popular enough yet. Moreover, if the teaching is mainly based on the teacher’s explanation, it will be boring. Therefore, there is a need to explore the teaching based on game design and combine teaching with fun, so that learning can become a more acceptable “game” for students, making the classroom atmosphere more active and improving the teaching quality of the classroom.","PeriodicalId":360004,"journal":{"name":"2021 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125022463","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}

Obviously, under the combination of high electric field and thermal stress, materials’ ageing and even failure are inevitable when the equipment runs for a long time. Previous studies have shown that the insulation characteristics of PP polymer dielectrics are mainly related to temperature and electric field strength. However, different electric field types and electric field uniformity also significantly affect the insulation performance of PP materials. In this paper, the insulation performance of polypropylene film samples was tested by changing the experimental factors such as electric field intensity, electric field unevenness, temperature and electric field type under the control of other experimental conditions. The experimental results show that the failure time of PP polymer decreases with increasing electric field strength, electric field uniformity or temperature. Electric field and temperature play essential roles in polymer ageing and decomposition. Unlike the results under AC voltage, PP film has longer decomposition time under the DC field and is less sensitive to temperature. In addition, the morphology of the samples was observed by the magnifying glass to illustrate the decomposition mechanism.","PeriodicalId":360004,"journal":{"name":"2021 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128362705","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}
