| 1 | Crack monitoring method based on Cu coating sensor and electrical potential technique for metal structure显示文摘Advanced crack monitoring technique is the cornerstone of aircraft structural health monitoring.To achieve real-time crack monitoring of aircraft metal structures in the course of service,a new crack monitoring method is proposed based on Cu coating sensor and electrical potential difference principle.Firstly,insulation treatment process was used to prepare a dielectric layer on structural substrate,such as an anodizing layer on 2A12-T4 aluminum alloy substrate,and then a Cu coating crack monitoring sensor was deposited on the structure fatigue critical parts by pulsed bias arc ion plating technology.Secondly,the damage consistency of the Cu coating sensor and2A12-T4 aluminum alloy substrate was investigated by static tensile experiment and fatigue test.The results show that strain values of the coating sensor and the 2A12-T4 aluminum alloy substrate measured by strain gauges are highly coincident in static tensile experiment and the sensor has excellent fatigue damage consistency with the substrate.Thirdly,the fatigue performance discrepancy between samples with the coating sensor and original samples was investigated.The result shows that there is no obvious negative influence on the fatigue performance of the 2A12-T4 aluminum alloy after preparing the Cu coating sensor on its surface.Finally,crack monitoring experiment was carried out with the Cu coating sensor.The experimental results indicate that the sensor is sensitive to crack,and crack origination and propagation can be monitored effectively through analyzing the change of electrical potential values of the coating sensor. | Hou Bo He Yuting Cui Ronghong Gao Chao Zhang Teng | 2015 | Chinese Journal of Aeronautics2015，28，3： | 10 |
| 2 | Orchid conservation in China from 2000 to 2020:Achievements and perspectives显示文摘We review achievements in the conservation of orchid diversity in China over the last 21 years.We provide updated information on orchid biodiversity and suggestions for orchid conservation in China.We outline national policies of biodiversity conservation,especially of orchid conservation,which provide general guidelines for orchid conservation in China.There are now approximately 1708 known species of Orchidaceae in 181 genera in China,including five new genera and 365 new species described over the last 21 years.The assessment of risk of extinction of all 1502 known native orchid species in China in 2013 indicated that 653 species were identified as threatened,132 species were treated as data-deficient,and four species endemic to China were classified as extinct.Approximately 1100 species(ca.65%)are protected in national nature reserves,and another~66 species in provincial nature reserves.About 800 native orchid species have living collections in major botanical gardens.The pollination biology of 74 native orchid species and the genetic diversity and spatial genetic structure of 29 orchid species have been investigated at a local scale and/or across species distributions.The mycorrhizal fungal community composition has been investigated in many genera,such as Bletilla,Coelogyne,Cymbidium,Cypripedium,and Dendrobium.Approximately 292 species will be included in the list of national key protected wild plants this year.Two major tasks for near future include in situ conservation and monitoring population dynamics of endangered species. | Zhihua Zhou Ronghong Shi Yu Zhang Xiaoke Xing Xiaohua Jin | 2021 | Plant Diversity2021，43，5： | 10 |
| 3 | Structural Surface Crack Monitoring Method Based on Electrical Potential Technique and Modern Surface Technology显示文摘Crack monitoring plays a great role in modern structural health monitoring, however, most of the conventional crack inspections have disadvantages in terms of the accuracy, expense, reliability, durability and level of instrumentation required. Thus, development of a simple and reliable crack inspection technique that allows continuous monitoring has been desired. In this paper, electrical potential technique and modern surface technology are employed together to develop a new structural surface crack monitoring method. A special crack monitoring coating sensor based on electrical potential technique was deposited on the hot spot of the structure by modern surface technology. The sensor consists of three layers: the isolated layer, the sensing layer and the protective layer. The isolated layer is prepared by anodic oxidation technology, the sensing layer is made of ion plated copper, and the protective layer is made of silicone. The thickness of each layer is at micrometer magnitude. The electrical conductivity of the sensor is very stable, and the fatigue performance of the specimen with or without coating sensor is nearly unchanged. The crack monitoring experiment result shows that there are two sudden rises of the coating sensor electrical potential values, corresponding to different stages of the crack initiation and propagation. Since the width of the surface coating sensor is only 0.5 mm, this crack monitoring sensor can detect the propagation of cracks less than 0.5 mm long. The method proposed takes the simplicity of electrical potential technique and can monitor surface crack of nearly all kinds of structures precisely. The results of this paper may form the basis of a new crack monitoring system. | CUI Ronghong HE Yuting YU Zhiming LI Hongpeng SHU Wenjun DU Jinqiang | 2011 | Chinese Journal of Mechanical Engineering2011，24，4： | 7 |
| 4 | Orchid diversity in China:Recent discoveries显示文摘Orchidaceae are among the largest plant families of angiosperms,with approximately 750 genera and 28,500 species around the world(Chase et al.,2015).The orchids have been considered a flagship of conservation biology(Zhang et al.,2015;Fay,2018;Liu et al.,2020),and all species have been included in CITES(Convention on International Trade in Endangered Species of Wild Fauna and Flora)Appendix I or II.Over the last two decades,there has been major progress in the classification of Orchidaceae.An updated classification with five subfamilies and 22 tribes(including three new tribes)has been proposed(Chase et al.,2015).Generic classifications in Collabieae,Epidendreae,Malaxideae,Neottieae,Orchideae,Podochileae and Vandeae have been discussed(Xiang et al.,2012a,2012b,2013,2014;Jin et al.,2014;Kocyan and Schuiteman,2014;Zhai et al.,2014;Tang et al.,2015;Raskoti et al.,2016;Simo-Droissart et al.,2018;Yan Peng et al.,2018).The generic delimitation of Orchidaceae in China has been discussed(Jin et al.,2015). | Zhihua Zhou Ronghong Shi Yu Zhang Xiaohua Jin | 2021 | Plant Diversity2021，43，5： | 3 |
| 5 | Analysis of Focusing Orbital Angular Momentum Wave Using Fabry-Perot Cavity显示文摘One of the biggest obstacles to the application of orbital angular momentum(OAM)in the microwave field is its divergence problem.This paper presents a full analysis of generating and focusing OAM waves using original and improved Fabry-Perot(F-P)cavities.Utilizing combination of microstrip antenna and original F-P cavity,the gain of the OAM antenna is enhanced from 4.0 dBi to 9.3 dBi and the corresponding divergence angle is decreased from 41to 24.To further improve the performance of the OAM antenna,the improved F-P cavity is introduced.The simulated results show that the gain is further enhanced to 12.0 dBi and the divergence angle is further decreased to be 15. | Yu Yao Xianling Liang Ronghong Jin Junping Geng | 2019 | Journal of Communications and Information Networks2019，4，3： | 1 |
