Abstract： The clinical term normalization has important research significance for dealing with the problem of non-standardization of clinical terminology in electronic medical records. The current mainstream solution is to adopt a "recall-sort" strategy. Based on the dataset provided in Evaluation 3 of the China Conference of Health Information Processing, we propose a multi-strategy-based normalization method for clinical terms. In the recall phase, the full-matching strategy, standard words recommendation of similar original words, and similarity calculation based on the TF-IDF and the improved Jaccard coefficient are used to recall the candidate standard word set. At the same time, we construct a standard quantity prediction model based on the BERT model, and use adversarial training, focal loss and label smoothing strategies to effectively improve the prediction performance and generalization performance of the models. In the ranking stage, In the ranking stage, we use the BERT implicit score ranking model based on adversarial training and fusion of diagnostic information to rank the candidate word set, and then generate the final predicted standard words based on the output of the quantity prediction model. In the final evaluation test set, the method accuracy rate of our method reached 0.6356, ranking second place among the participating teams.

Abstract： As an emerging concept, metaverse has attracted extensive attention from industry, academia and scientific research field. The combination of agriculture and metaverse will greatly promote the development of agricultural informatization and agricultural intelligence, provide new impetus for the transformation and upgrading of agricultural intelligence. Firstly, to expound feasibility of the application research of metaverse in agriculture, the basic principle and key technologies of agriculture metaverse were briefly described, such as blockchain, non-fungible token, 5G/6G, artificial intelligence, Internet of Things, 3D reconstruction, cloud computing, edge computing, augmented reality, virtual reality, mixed reality, brain computer interface, digital twins and parallel system. Then, the main scenarios of three agricultural applications of metaverse in the fields of virtual farm, agricultural teaching system and agricultural product traceability system were discussed. Among them, virtual farm is one of the most important applications of agricultural metaverse. Agricultural metaverse can help the growth of crops and the raising of livestock and poultry in the field of agricultural production, provide a three-dimensional and visual virtual leisure agricultural experience, provide virtual characters in the field of agricultural product promotion. The agricultural metaverse teaching system can provide virtual agricultural teaching similar to natural scenes, save training time and improve training efficiency by means of fragmentation. Traceability of agricultural products can let consumers know the production information of agricultural products and feel more confident about enterprises and products. Finally, the challenges in the development of agricultural metaverse were summarized in the aspects of difficulties in establishing agricultural metaverse system, weak communication foundation of agricultural metaverse, immature agricultural metaverse hardware equipment and uncertain agricultural meta universe operation, and the future development directions of agricultural metaverse were prospected. In the future, researches on the application of metaverse, agricultural growth mechanism, and low power wireless communication technologies are suggested to be carried out. A rural broadband network covering households can be established. The industrialization application of agricultural meta universe can be promoted. This review can provide theoretical references and technical supports for the development of metaverse in the field of agriculture.

Abstract：常规变频电源能实现独立供电功能，但无法达到无缝并网供电的要求。在 变频电源为船舶提供供电前，必须先停止船舶主发电机组的供电。反之，也必须先停 止变频电源系统的供电，然后才能恢复船舶发电机组的供电。本文重点讨论岸电系统 的多机并联技术，采用微电网应用技术设计变频岸电电源系统，模拟船舶发电机的工 作原理，通过电源检测传感器实时检测船舶电网的电压和频率，实时调整系统输出 电源的电压和频率，以达到两者的同步，从而实现变频岸电电源系统的无缝并网供电 功能。
