| 6 | Computer simulation of flow fields for quenching medium显示文摘Using finite element method (FEM), the com-plex flow fields of quenching medium in a quenching tank are calculated for the cases with and without a work-piece in it. The influence of the flow homogenization device on the flow fields is studied. The computer simulation results are in consistency with the actual measurement results. According to the simulated results, the structure of the quenching tank and the flow homogenization device are optimized and more uniform flow fields are obtained. | LI Qiang, WANG Ge, CHEN Nailu, LIAO Bo & WANG Tongzhen College of Mechanical Engineering, Yanshan University, Qinhuangdao 066004, China Correspondence should be addressed to Li Qiang (e-mail: Liqiang@ ysu.edu.cn) | 2003 | Chinese Science Bulletin2003，48，8： | 1 |

| 10 | Observation on the Therapeutic Effects of Wenjing Decoction on Menstrual Disorders显示文摘Objective:To treat patients with menstrual disorders with Wenjing Decoction and analyze its therapeutic effects.Metlods:80 patients with menstrual disorders were selected as the research subjects,and they were divided into two groups(experimental group and control group),with each group given different treatment methods.The control group was given conventional Western medical treatment while the experimental group was given Wenjing Decoction treatment,and the effects of different treatment methods on the patients were compared.Results:The total number of effectively treated patients in the experimental group(39 cases,97.50%)was more than the that of the control group(25 cases,62.50%)。and the quality of life score of the experimental group(91.56±4.44 points)was higher that of the control group(81.72±3.19 points),and the number of menstnual recovery cycles(1.11±0.41)was less than that of the control group patients(2.42±1.25 times),P<0.05.Conclusion:The application of Wenjing Decoction for patients with menstrual disorders can significantly improve the treatment efficacy and is beneficial to improve the quality of life of the patients and shorten the number of cycles that menstruation starts to return to normal. | Diancui Zhang Junxia Cui Shuwen Gai Tongzhen Zhao Liqiang Wu | 2020 | Journal of Clinical and Nursing Research2020，4，6： | 0 |
| 11 | Research on a Multiport Parallel Type Hybrid Circuit Breaker for HVDC Grids:Modeling and Design显示文摘This paper proposes a star type multiport hybrid circuit breaker(Star-HCB)topology for protection of multiterminal DC transmission.Reliability and stability of high voltage DC(HVDC)grids are determined by their capabilities to withstand DC-side faults.In order to maintain reliability of HVDC grids,both ends of each line should be equipped with hybrid circuit breakers(HCB).This method will increase expenditure of the HVDC,especially the meshed topology.The n-port Star-HCB consists of ultra-fast mechanical disconnectors,load current switch and only one transferring branch which is formed by improved half-bridge sub-module.Compared with existing traditional hybrid circuit breakers and other multiport hybrid circuit breakers,the proposed topology can realize the same short-circuit blocking goal using fewer components.Detailed mathematical transient process calculation and timedomain simulation of the proposed Star-HCB are given to verify its superiority. | Xinming Guo Jin Zhu Qingpeng Zeng Hao Xiao Tongzhen Wei | 2023 | CSEE Journal of Power and Energy Systems2023，9，5： | 0 |

| 14 | DSFA: cross-scene domain style and feature adaptation for landslide detection from high spatial resolution images显示文摘Rapid and accurate landslide inventory mapping is significant for emergency rescue and post-disaster reconstruction.Nowadays,deep learning methods exhibit excellent performance in supervised landslide detection.However,due to differences between cross-scene images,the performance of existing methods is significantly degraded when directly applied to another scene,which limits the application of rapid landslide inventory mapping.In this study,we propose a novel Domain Style and Feature Adaptation(DSFA)method for cross-scene landslide detection from high spatial resolution images,which can leverage labeled source domain images and unlabeled target domain images to mine robust landslide representations for different scenes.Specifically,we mitigate the large discrepancy between domains at the dataset level and feature level.At the dataset level,we introduce a domain style adaptation strategy to shift landslide styles,which not only bridges the domain gap,but also increases the diversity of landslide samples.At the feature level,adversarial learning and domain distance minimization are integrated to narrow large feature distribution discrepancies for learning domain-invariant information.In addition,to avoid information omission,we improve the U-Net3+model.Extensive experimental results demonstrate that DSFA has superior detection capability and outperforms other methods,showing its great application potential in unsupervised landslide domain detection. | Penglei Li Yi Wang Tongzhen Si Kashif Ullah Wei Han Lizhe Wang | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 15 | Non-integrable Movement Equations in Landsliding System显示文摘The answer of the question was considered as non-integrable basically. The integrable system was thought in the exceptional.Since Poincare had presented in a theorem and proved that non-integrable system is normal, and yet integrable system is abuormal. In the landsliding system, discussed question was regarded to be true.Sortie fundamentals were considered; other systems and example with engineering control are concerned and discussed in details. | Yan Tongzhen(Faculty of Engineering, China University of Geosciences, Wuhan 430074)Wang Jianfeng(LNM, Institute of Mechanics, Chinese Academy of Sciences, Beijing 100080)Yan Lei(Beijing University of Aeronautics and Astronautics, Beijing 100083)Zhou Cuiyi | 1999 | Journal of Earth Science1999，18，4： | 0 |
| 16 | Forecasting and Decision-Making of Systematic Theories for Engineering Geology in Environmental Geoscience显示文摘The paper discusses the problems of engineering geology in environmental geoscience from several aspects. For natural sciences and social sciences, it deduces essential theory from logistic cycle model, logic mapping and Verhulst model. It had been discovered that these aspects are equal. However, these were the studies of normal effects. We must establish mathematical model to check from contrary course for gray forecasting and decision-making and answer several questions satisfactorily. | Wang Hongxing Yan Tongzhen Tang Huiming Teng Weifu(Faculty of Engineering, China University of Geosciences, Wuhan 430074) | 1999 | Journal of Earth Science1999，18，4： | 0 |
| 17 | Slippery quartz surfaces for anti‐fouling optical windows显示文摘The surface of camera‐based medical devices is easily smeared by blood and fog during the surgical procedure,causing visual field loss and bringing great distress to both doctors and patients.In this article,a slippery liquid‐infused porous surface(SLIPS)on a quartz window surface that can repel various liquids,especially blood droplets is reported.A femtosecond laser pulse train was used to create periodic microhole structures on the silica surface.The subsequent low surface energy treatment and lubricant infusion led to the successful preparation of a slippery surface.Such blood‐repellent windows exhibited high transparency,great antifogging,and antibacterial properties.In addition,the slippery ability of the as‐prepared surface exhibited outstanding stability since the surface could withstand harsh treatments/environments,such as repeated pipette scratches and immersion in different pH solutions.The as‐prepared millimeter‐sized quartz samples with SLIPS were attached to the endoscope lens as a protective coating and could maintain high visibility after repeated immersion in blood.We believe that the coating developed in this study will provide inspiration for the design of next‐generation endoscopes or other camera‐guided devices that will resist fouling,keep clear vision,and reduce operation time,thus offering great potential applications in lesion diagnosis and therapy. | Minjing Li Tongzhen Yang Qing Yang Shaokun Wang Zheng Fang Yang Cheng Xun Hou Feng Chen | 2023 | Droplet2023，2，1： | 0 |
