| 2 | Driving Force Model for Non-pneumatic Elastic Wheel显示文摘In order to obtain good driving performance,a driving force model is presented for non-pneumatic elastic wheel.Brush model of pneumatic tyres is introduced and the deformations of elastic supports and tread are also taken into account.The longitudinal slip rate is redefined.The grounding pressure distribution of elastic wheels is analyzed and corrected according to speed,temperature and stiffness.Then rolling resistance equation is developed.Finally,simulation is conducted by software CarSim,and the results show that the estimated values are consistent with simulation values,especially at low longitudinal slip rate.The research can help to optimize design of non-pneumatic elastic wheel. | Li Bo Zhao Youqun Zang Liguo Bei Shaoyi Fu Hongxun Zhang Lanchun | 2016 | Transactions of Nanjing University of Aeronautics and Astronautics2016，33，2： | 3 |
| 3 | From Redevelopment to In Situ Upgrading: Transforming Urban Village Governance in Shenzhen Through the Lens of Informality显示文摘The study on informality has experienced a shift from describing the spatial characteristics toward exploring the connotation of urban governance in recent years. This paper takes urban villages in Shenzhen, a typical informal settlement in China, as cases to analyze the two urban village governance modes of redevelopment and in situ upgrading and reveals the dynamics of the governance mode transformation. Through the lens of informality, this study focuses on the interaction among the government, the market, and former property owners on tenure legalization. The study finds that first of all, informality is the core of the transformation of urban village governance in Shenzhen. By strategically making use of informality, the government adopted different modes of urban village governance to fulfill the demands of urban development at different phases. Second, in the process of formalizing informal settlements through redevelopment, although the institutional framework is relatively complete, the boundary between informality and formality still changes continuously in property titling. While in the new governance mode of in situ upgrading in recent years, the government creates 'special areas' in informal settlements via approving their de facto tenure security, so as to attract market force to upgrade physical environment and social management. Through revealing the mechanism in the blurred area between informality and formality, this paper responds to the dualistic argument on the informality theory, deepens the idea of taking informality as a flexible urban governance strategy in developing countries, and provides new thoughts for governance of informal settlements in China and other developing countries. | Gan Xinyue Chen Yulin Bian Lanchun Qian Fang | 2019 | China City Planning Review2019，28，4： | 2 |
| 4 | Transformation of Urban Design from the Perspective of Society-Space Relationship显示文摘The New Urban Agenda approved at Habitat III – The United Nations Conference on Housing and Sustainable Urban Development in 2016, promises to achieve the urban transition toward sustainability in response to future challenges facing cities worldwide. In the current context of new urbanization in China, urban development is experiencing a transition from incremental development to regeneration. In order to realize people-oriented objectives, planners need to gain scientific understanding of urban development and grasp the basic concepts of urban design and value orientation, so that they can shape spaces that meet diverse needs, achieve social inclusion and enhance the quality of urban life. The purpose of this paper is to reiterate the importance of studying urban development from the 'society-space' perspective and the concern about its values in urban design. The paper analyzes and discusses the characteristics of urban development and changes in social needs that appear in the practice of urban design from the perspective of society-space relationship. In addition, it emphasizes the spatial-temporal characteristics and value orientation in the development of urban design theory and practice. Considering China's current urban background, the paper also argues that the current transformation of urban design practice needs to be guided by theories on human settlements and reinforce three important aspects of urban design characteristics and values: seeking truth from science, seeking kindness in humanities, and seeking beauty through art. | Bian Lanchun Chen Mingyu Qian Fang | 2019 | China City Planning Review2019，28，1： | 1 |

| 9 | Physicochemical properties, molecular structure, antioxidant activity, and biological function of extracellular melanin from Ascosphaera apis显示文摘Ascosphaera apis spores containing a dark-colored pigment infect honeybee larvae,resulting in a large-scale collapse of the bee colony due to chalkbrood disease.However,little is known about the pigment or whether it plays a role in bee infection caused by A.apis.In this study,the pigment was isolated by alkali extraction,acid hydrolysis,and repeated precipitation.Ultraviolet(UV)analysis revealed that the pigment had a color value of 273,a maximum absorption peak at 195 nm,and a high alkaline solubility(7.67%)and acid precipitability.Further chemical structure analysis of the pigment,including elemental composition,Fourier transform infrared(FTIR)spectroscopy,Raman spectroscopy,mass spectrometry,and nuclear magnetic resonance(NMR),proved that it was a eumelanin with a typical indole structure.The molecular formula of melanin is C10H6O4N2,and its molecular weight is 409 Da.Melanin has hydroxyl,carboxyl,amino,and phenolic groups that can potentially chelate to metal ions.Antioxidant function analyses showed that A.apis melanin had a high scavenging activity against superoxide,hydroxyl,and 2,2-diphenyl-1-picrylhydrazyl(DPPH)radicals,and a high reducing ability to Fe3+.Indirect immunofluorescence assay(IFA),scanning electron microscopy(SEM),and transmission electron microscopy(TEM)analyses showed that A.apis melanin was located on the spore wall.The spore wall localization,antioxidant activity,and metal ion chelating properties of fungal melanin have been suggested to contribute to spore pathogenicity.However,further infection experiments showed that melanin-deficient spores did not reduce the mortality of bee larvae,indicating that melanin does not increase the virulence of A.apis spores.This study is the first report on melanin produced by A.apis,providing an important background reference for further study on its role in A.apis. | Zhi LI Hui HENG Qiqian QIN Lanchun CHEN Yuedi WANG Zeyang ZHOU | 2022 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022，23，5： | 0 |
| 10 | Inheritance and Development of Guangxi Minority Musical Instruments and Their Integration With Operas显示文摘The traditional musical instrument of minorities converges the evolution of ethnic group culture and history,and ethnic musical instruments are a core component of minority culture.The traditional instruments of Guangxi minorities are rich and varied,and an all-round cultural inheritance and protection mechanism should be used for ethnic musical instruments,so that the performance form of classical musical instruments of minorities can be more widely understood and mastered.Therefore,in this paper,we discuss the specific practice idea of the inheritance and development of classical musical instruments of Guangxi minorities,and facilitate the innovation of development path of ethnic musical instruments by taking the inheritance form of integrating musical instruments with operas. | HUANG Lanchun | 2023 | Psychology Research2023，13，9： | 0 |
