1Characteristics,timing,and offsets of the middle-southern segment of the western boundary strike-slip fault of the Songliao Basin in Northeast China显示文摘作为 Songliao 盆和 Da Hinggan 山的东方边缘的西方边界差错, Nenjiang-Balihan 差错位于东北中国的中央部分。是一个巨大的深层的 NNE 惹人注目的差错传统地被认为,由一个正常差错或分开差错排水量描绘了。域调查导致了发现可锻砍在 Lingxia 和 Louzidian 区域,中间和差错系统的南部的扇区的地区。作者在这个领域里进行了结构的元素的大小,微结构研究,有限紧张大小,石英的比较喜欢的水晶取向上的研究用电子背决定了散布使变形的岩石的衍射和白云母 40Ar/39Ar 年表在可锻砍地区。变丑 Lingxia 和 Louzidian 展示的结果表演可锻砍地区是类似的,并且他们代表一个连续差错,即, Nenjiang-Balihan 的中间南部的片断指责在早白垩纪(130 妈) 的可锻的砍,它经历了左首的罢工滑倒。由在 Nenjiang-Balihan 差错的双方上测量 Xar 蠢人河缝术和 Wolegen 组的排水量,差错的累积罢工滑倒偏移量是大约 4050 km,这被发现。HAN GuoQing LIU YongJiang Franz NEUBAUER Johann GENSER ZOU YunXin LI Wei LIANG ChenYue 2012Science China Earth Sciences2012,55,3:7
2Ultra-compact broadband polarization beam splitter with strong expansibility显示文摘Based on the traditional directional coupler, we proposed a scheme to design on-chip polarization beam splitters using an inverse design method. In our scheme, the coupling area of the designed devices are only 0.48 μm× 6.4 μm. By manipulating the refractive index of the coupling region, the devices can work in C-band,L-band, O-band, or any other communication band. Different from conventional design methods, which need to adjust the design parameters artificially, if the initial conditions are determined, the proposed scheme can automatically adjust the design parameters of devices according to specific requirements. The simulation results show that the insertion losses of the designed polarization beam splitters can be less than 0.4 dB(0.35 dB) for TE(TM)mode at the wavelengths of 1310, 1550, and 1600 nm, and the extinction ratios are larger than 19.9 dB for the TE and TM modes at all three wavelengths. Besides, the extinction ratios of both polarization states are more than 14.5 dB within the wavelength range of 1286–1364 nm, 1497–1568 nm, and 1553–1634 nm. At the same time,the insertion losses are smaller than 0.46 dB.JIE HUANG JUNBO YANG DINGBO CHEN XIN HE YUNXIN HAN JINGJING ZHANG ZHAOJIAN ZHANG 2018Photonics Research2018,6,6:3
3Distributions of surficial sediments and its response to dynamic actions in the Xiamen Bay sea area, China显示文摘Sediment distribution is important for morphodynamic evolution and shoreline changes in coastal zones and estuaries. In the study, the data of 230 surface sediment samples collected from the Xiamen Bay sea area in September 2008 are used to investigate the spatial distribution and sediment transport pathway. The grain size distribution of surficial sediments in the Xiamen Bay area is shown distinctly in this study. In addition, the Grain Size Transport Analysis model is used for conveying trend analysis of the sediment in this area, particularly for determining the sediment movement trend. The results indicate that eight sediment types are present for samples, with clayey silt comprising the highest percentage in the study area at 65.22%. Moreover, in the different subareas, the characteristics of grain size parameters are obviously different owing to different sediment sources and hydrodynamic conditions. Furthermore, runoff, tides, and waves are the main forces dominating sediment dynamics on the seabed and tidal flats, and the sediment movement trend is closely related to hydrodynamic conditions.ZUO Shuhua HAN Zhiyuan HUANG Yunxin HAN Jie XIE Mingxiao 2016Acta Oceanologica Sinica2016,35,4:1
4高寒草地土壤掩埋对凋落物分解速率的影响大于氮素富集显示文摘由于高寒草地退化、鼠害严重、大风频繁等原因,凋落物被频繁掩埋在土壤中。但凋落物的位置变化和氮富集对高寒草原凋落物分解速率和养分动态影响的认识尚不清楚。为了研究凋落物位置变化(地表、掩埋10 cm和悬空60 cm)和氮富集对高寒草原优势植物凋落物分解的影响,本研究依托2009年在新疆天山巴音布鲁克高寒草原设置的长期模拟氮沉降研究平台,以对照和氮富集处理样方的优势植物羊茅(Festuca ovina)和赖草(Leymus tianschanicus)凋落物为试验材料,测定分解过程中凋落物质量损失和碳氮磷含量的变化特征。研究结果表明,掩埋凋落物分解速率显著快于地表凋落物,悬空处理凋落物分解速率慢于地表凋落物。氮富集显著影响凋落物质量,进而影响凋落物分解。而凋落物质量残留在对照与氮富集土壤掩埋之间无显著差异。这些结果表明,氮富集通过凋落物质量而不是通过土壤环境因素,影响短期凋落物分解。不同处理的所有试验凋落物均有碳和磷的释放现象。对照处理的凋落物,凋落物氮以累积为主,而氮富集处理的凋落物,凋落物氮以释放为主。这表明凋落物分解可能受到氮元素限制,氮富集改变了凋落物分解调控的氮循环过程。本研究提供了直接证据,掩埋处理的凋落物有更快的质量损失和碳元素释放,土壤掩埋是旱地凋落物分解速率比模型预测的快的一个候选解释。Yuan Su Jiajia Le Xiaofei Ma Xiaolong Zhou Yunxin Zhang Yanming Gong Wenxuan Han Kaihui Li Xuejun Liu 2021Journal of Plant Ecology2021,14,6:0
5畅享自然——让老年人乐享幸福生活的生态社区公园设计显示文摘为了更好地照顾老年人,护理模式正在一步步由家庭护理向社区护理转变。该项目以自然恢复、低影响发展、自我维持的生态社区为设计理念,旨在创造一个健康舒适的户外空间,为老年人提供互动、娱乐和教育服务,加强老年人与家人之间的联系,并完善社区内外的社交网络。项目地址位于安徽省合肥市中心的仙桥社区。该社区占地0.46平方公里,有6个相对独立的居民区。原有社区景观设计陈旧,建筑密度高,仅有一个公共广场和一个袖珍公园,区域内居民很少有接触到绿色和自然的机会。Peng Chen Yichen Lou Kun Qian Zhengwei Xing Yunxin Han Wenjun Liu Hongbo Chen Wenqi Chen Xinmiao Zhu Lang Qin Xueying Liu Yu Leng Xinya Hu Suheng Yao 2023工业设计2023,,9:0
