| 1 | The Phototropism of Jurassic Petrified Wood in North China Plate显示文摘Trees on the side directly exposed to sunlight generally grow faster than on the opposite side,a phenomenon termed plant phototropism.There are in situ vertical trunks of silicified wood in the Xiadelongwan area of Yanqing County,north Beijing,where the first National Geologic Park of Petrified Wood of China has been built since 2002.A few trunks have well-preserved growth rings.One petrified stump from the formation shows a positive phototropism direction of SW23O0.As compared with the modern normal growth stumps in Beijing plain area,which have a positive phototropism direction of SW210 °± 5°,the evidence of wood phototropism supports the conclusion of previous palaeomagnetic studies that the North China Plate has rotated clockwise since the Late Jurassic.The known petrified wood stumps in the Yanshan-Liaoning area are mainly found from the strata of 165-136 Ma,which corresponds to the main stage of the Yanshanian Movement. | JIANG Zikun LIU Benper HUANG Min DENG Shenghui LU Yuanzheng LIU Lu LI Mingming DONG Shuxin WANG Yongdong | 2014 | Acta Geologica Sinica(English Edition)2014，88，5： | 1 |
| 2 | The Relationship between Phototropism and Plate Motion显示文摘Objective Plant phototropism means that trees on the side directly exposed to sunlight generally grow faster than those on the opposite,and positive phototropism is easy to observe in crown and trunk.In this study,we chose the transverse section of tree trunk to observe.The definitive intensity of plant phototropism ranges regularly from strong to | JIANG Zikun HUANG Min LIU Benpei LU Yuanzheng DENG Shenghui WANG Yongdong | 2017 | Acta Geologica Sinica(English Edition)2017，91，1： | 0 |
| 3 | A survey of urban visual analytics:Advances and future directions显示文摘Developing effective visual analytics systems demands care in characterization of domain problems and integration of visualization techniques and computational models.Urban visual analytics has already achieved remarkable success in tackling urban problems and providing fundamental services for smart cities.To promote further academic research and assist the development of industrial urban analytics systems,we comprehensively review urban visual analytics studies from four perspectives.In particular,we identify 8 urban domains and 22 types of popular visualization,analyze 7 types of computational method,and categorize existing systems into 4 types based on their integration of visualization techniques and computational models.We conclude with potential research directions and opportunities. | Zikun Deng Di Weng Shuhan Liu Yuan Tian Mingliang Xu Yingcai Wu | 2023 | Computational Visual Media2023，9，1： | 0 |
