Abstract： Purpose/Significance In recent years, the national leadership has attached great importance to the inheritance and innovation of China’s excellent traditional culture, and the concepts of creative transformation and innovative development are constantly evolving. The Ministry of Science and Technology of China, among six departments, jointly formulated the Guidelines for Promoting the Deep Integration of Culture and Technology , proposing to form a cultural and technological integration innovation system covering key areas and critical links, to achieve the goal of in-depth integration of culture and technology . Intangible cultural heritage (ICH), as an essential part of China’s excellent traditional culture, plays a crucial role in consolidating the sense of the Chinese national community and enhancing cultural self-confidence. This paper discusses the research paths for the creative transformation and innovative development of ICH in the context of culture and technology integration, emphasizing the significant role of modern technology in promoting the transformation and development of ICH. Method/Process The paper first interprets the connotation of creative transformation and innovative development in ICH, and clarifies the theoretical foundation and guiding principles of creative transformation and innovative development in ICH. It then analyzes the significant contributions of creative transformation and innovative development in ICH to society, economy, and cultural diversity, as well as the categorized scenarios of technology empowerment in creative transformation and innovative development of ICH. It discusses six types of common key technologies that enable technology-driven creative transformation and innovative development in ICH, including digital technology, virtual and augmented reality, big data analysis, artificial intelligence, cloud computing, and the Internet of Things. It summarizes a three-tier framework system for technology-driven creative transformation and innovative development in ICH, namely the method layer, technology layer, and object layer, forming a progressive relationship from theory to technology and then to specific practices. Finally, by integrating the specific example of the traditional craft of Wuhu iron painting, it demonstrates the facilitating role of modern technology in the creative transformation and innovative development of ICH and its impact on the protection, inheritance, and innovative development of ICH. Results/Conclusions The findings suggest that technological means can effectively protect and inherit ICH, facilitating its creative transformation and innovative development. However, it also requires careful consideration and precautions against the potential risks and challenges that modern technology poses to ICH projects in terms of intellectual property rights, the digital divide, and the indirect nature of experiences. Looking to the future, with the emergence of more innovative technologies, modern technology will not only help to protect and pass on traditional culture but also give new connotations and expressions to traditional culture, ensuring that its unique value and charm continue to play out in an ever-changing world.

Abstract： [Purpose/significance] The external translation of excellent books in the humanities and social sciences is an important way for Chinese culture to go abroad. Establishing an external translation book evaluation system can demonstrate the influence of books and provide guidance for the selection of content types of external translation books. [Method/process] From the 10 dimensions that reflect the academic influence and social influence of the external translation books, the evaluation indicators are refined. Using the entropy weight method to calculate the weights of each index, the comprehensive scores of academic influence and social influence are calculated by weighted averaging, and then an empirical analysis is performed on the external translation books which are funded by Chinese academic translation project. [Result/conclusion] The absolute value of the difference between domestic and foreign impact rankings of 40.84% books is greater than 10; the external translation of books with high domestic academic influence have not attracted the attention of foreign scholars; the social influence of external translation books is generally lower. When selecting the content type of an external translation book, it is necessary to examine the academic influence and social influence of the book both at home and abroad.

Abstract： Soil salinization seriously impacts wheat (Triticum aestivum L. ) production. Improving salinity tolerance is one of the main biological approaches responding to the problem. The germination stage is also sensitive to salt, and the salt tolerance at the germination stage is very important for wheat planting in saline-alkali land. In order to explore the feasibility of using physiological indexes of leaves to evaluate salt tolerance of wheat at germination stage, CM6005 and its 73 sodium azide mutagenesis families were used as experimental materials. The contents of proline, soluble sugar, total protein and soluble protein, as well as the activities of peroxidase (POD), catalase (CAT) and superoxide dismutase (SOD) in the leaves were measured under the conditions of ultra-pure water and 40% artificial sea water, and principal component analysis and cluster analysis were used to evaluate the salt tolerance of the wheats. The results were as follows: (1) Under 40% artificial sea water salt stress, the contents of proline and soluble sugar increased, but the contents of total protein and soluble protein decreased. The activity of peroxidase(POD) increased, and the catalase(CAT) and superoxide dismutase(SOD) activity decreased. (2) In principal component analysis, the first and the fourth principal components were two factors of the response of salt-tolerant enzyme system, and the second and third principal components were mainly two factors of osmotic adjustment of salt tolerance in wheat leaves at the stage of germination. (3) In the evaluation of salt tolerance, the salt tolerance grade of CM6005 was 2(salt tolerance) , and the salt tolerance grade of the lines was 1(high salt tolerance), which were SAM1, SAM49 and SAM59. On the whole, the activity of peroxidase (POD), catalase (CAT) and superoxide dismutase (SOD) as well as the content of proline and soluble sugar could be used as physiological indexes to evaluate the salt tolerance of wheat at germination stage. These results can be used as a reference for the evaluation of salt tolerance in wheat based on physiological indexes of leaves at the germination stage.

Abstract： In order to optimize the permanent magnet synchronous motor(PMSM) used in industrial robots with 36 slots and 8 poles, the structure of eccentric and concave stator tooth is proposed. This structure is based on the thinking of different air gap length, and the finite element analysis software ANSYS Maxwell is used to model and analyze the PMSM with the structure. The total harmonic distortion of the air gap magnetic field, the total harmonic distortion of the back EMF, the torque ripple coefficient under different eccentric distances are studied, and the influence of the structure of eccentric and concave stator tooth for cogging torque is analyzed. The simulation experiment results show that the structure of eccentric and concave stator tooth can effectively improve the air gap flux density waveform, and reduce output torque ripple and amplitude of cogging torque.

Abstract： The BiLSTM neural network model has long training time and can not fully learn text context informations. In order to solve the problems, this work proposes a text emotion classification model based on BiGRU-Attention neural network. Firstly, the bidirectional Gated Recurrent Unity (BiGRU) neural network layer was used to extract the features of the deep text information; secondly, the attention mechanism (Attention) layer was used to allocate the corresponding weight of the extracted text deep information. Finally, the text feature messages of different weights are put into the softmax function layer to carry out the text sentiment classifications. The experimental results show that the accuracy of the proposed neural network model is 90.54% on the IMDB data set, the loss rate is 0.2430 and the time cost is 1100s and the validity of the BiGRU-Attention model is verified.

Abstract： Based on understanding of theory and practice, Handle System will coexist with the Domain Name System for a long time in the future, however, resolution protocols and identifier code rules of two identifier resolution system are incompatibility, leading to a barrier between data space of them. Therefore, it is urgent for us to resolve the connectivity problem of two identifier resolution system currently. By analyzing pros and cons of existing solutions, we found that the separation of protocol data unit and protocol can solve the incompatibility problem of resolution protocol and identifier code rule of two systems. Based on such a separation mechanism, inter-operation mechanism of Handle System and Domain Name System based on the proxy server was developed. Simulation experiments show that compared with traditional client-server ones, the response time of this new mechanism increases a little and is within the acceptable range.
