1Preliminary Study on Magnetic Induction Intensity Induced by Plasma During Hypervelocity Impact显示文摘An experimental system has been built to produce and measure the magnetic field in the backward ejected matter during hypervelocity impact.The designs of measurement system and coil,the choice of associated equipment,and the system calibration are also described in detail.The measurement of magnetic induction intensity for different given coil positions and azimuth angles are performed with two-stage light-gas gun.On condition that impact velocities are approximately equal and incidence angles are 45°,60° and 90° respectively,the relationship between average magnetic induction intensity and impact angle at different time spans is obtained.Experimental results show that the average magnetic induction intensity with incidence angle of 90° is larger than those with incidence angles of 45°and 60°.Tang Enling Zhang Qingming Zhang Jian 2009Chinese Journal of Aeronautics2009,22,4:13
2The Impacts of Urbanization on the Distribution and Body Condition of the Rice-paddy Frog(Fejervarya multistriata) and Gold-striped Pond Frog(Pelophylax plancyi) in Shanghai,China显示文摘Previous studies have suggested that urbanization presents a major threat to anuran populations. However, very few studies have looked at the relationship between urbanization and anuran body condition. We investigated whether the distribution and body condition of the rice-paddy frog(Fejervarya multistriata) and gold-striped pond frog(Pelophylax plancyi) are influenced by increasing urbanization in Shanghai, China. Four study sites with six indicators of the major land-cover types were scored to indicate their position on an urbanization gradient. We found that both the density and body condition of F. multistriata declined significantly along this gradient. Although we observed a significant difference in body condition of P. plancyi among study sites with different degrees of urbanization, we did not find any corresponding significant differences in population density. Our results indicate that both the densities and body condition of these two anuran species show a negative relationship with increasing urbanization, but that the density of P. plancyi was only slightly affected in Shanghai.Ben LI Wei ZHANG Xiaoxiao SHU Enle PEI Xiao YUAN Yujie SUN Tianhou WANG Zhenghuan WANG 2016Asian Herpetological Research2016,7,3:9
3Major Factors Affecting the Distribution of Anuran Communities in the Urban, Suburban and Rural Areas of Shanghai, China显示文摘There is a dearth of information on the effects of landscape and microhabitat variables on the distribution of anurans in areas of rapid urban development, in both tropical and subtropical regions. Therefore, we studied 24 wetlands sites from the center of Shanghai city, China extending outward to rural areas. Sampling was performed from May through July 2014. Urbanization was categorized by the proportion of hard ground cover. Transect sampling and ‘calling' surveys were used to investigated the richness and density of anurans; microhabitat factors were recorded simultaneously. One-way analysis of variance and Kruskal–Wallis tests were conducted to analyze differences of total density, species richness and density of individual anuran species in the three urbanization levels; redundancy analysis was carried out on the relationship between anuran density and environmental variables. Species richness was lowest in the areas where the proportion of hard ground cover was > 80%, and the total density of anurans was highest in the areas where coverage of the hard ground cover was < 30%. We recorded five species belonging to four genera and four families and an individual anuran species that had varied representations in urban environments. Beijing gold-striped pond frogs(Pelophylax plancyi) and Zhoushan toads(Bufo gargarizans) appeared to be well adapted to the Shanghai metropolis. Large water environments and aquatic vegetation(floating-leaves and emergent vegetation) were indicators of the presence of Beijing gold-striped pond frogs. The density of black-spotted pond frog(Pelophylax nigromaculatus) was at the lowest density in the areas where hard ground coverage was > 80%, and tended to prefer larger bodies of water. Hong Kong rice-paddy frogs(Fejervarya multistriata) and ornamented pygmy frogs(Microhyla achatina) both suffered severely from cropland loss due to urban development. Bare land around breeding grounds was important for Hong Kong rice-paddy frogs, since it usually chooses mud coast caves for hibernation.Xiaoxiao SHU Wei ZHANG Ben LI Enle PEI Xiao YUAN Tianhou WANG Zhenghuan WANG 2016Asian Herpetological Research2016,7,4:6
4Progress in polymer solar cell显示文摘This review outlines current progresses in polymer solar cell. Compared to traditional silicon-based photovoltaic (PV) technology, the completely different principle of optoelectric response in the polymer cell results in a novel configuration of the device and more complicated photovoltaic generation proc-ess. The conception of bulk-heterojunction (BHJ) is introduced and its advantage in terms of mor-phology is addressed. The main aspects including the morphology of photoactive layer, which limit the efficiency and stability of polymer solar cell, are discussed in detail. The solutions to boosting up both the efficiency and stability (lifetime) of the polymer solar cell are highlighted at the end of this review.LI LiGui LU GuangHao YANG XiaoNiu ZHOU EnLe 2007Chinese Science Bulletin2007,52,2:4
5A New Record of Kaloula(Amphibia: Anura: Microhylidae) in Shanghai, China显示文摘We discovered a medium-sized species of narrow-mouthed frog of the genus Kaloula in June and September 2014 during municipal surveys of amphibians in Shanghai. Three narrow-mouthed frogs were collected in city drains of the Binjiang Forest Park, Shanghai. Based on subsequent examination and morphological characters, these specimens were identified as Kaloula borealis(Barbour, 1908). The species was mainly distributed in Northern China and Korea. It is a new amphibian record for Shanghai. We found the visible differences in male secondary sexual characteristics between our specimens and Beijing specimens. K. borealis was first described inhabiting urban greenlands which could benefit amphibian conservation in urban and urbanizing areas.Wei ZHANG Ben LI Xiaoxiao SHU Hanbin XIE Enle PEI Xiao YUAN Yujie SUN Tianhou WANG Zhenghuan WANG 2015Asian Herpetological Research2015,6,3:3
