| 1 | A digital earth prototype system:DEPS/CAS显示文摘Digital Earth is an information expression of the real Earth,and is a new way of understanding the Earth in the twenty-first century.This paper introduces a Digital Earth Prototype System(DEPS)developed at the Chinese Academy of Sciences(CAS)and supported by the Knowledge Innovation Program of the Chinese Academy of Sciences.Discussions are made to the theoretical model and technical framework of the Digital Earth,and its related key technologies on spatial information processing,spatial data warehouse technology,virtual reality technology,high-performance and parallel computing.The DEPS consists of seven sub-systems including the spatial data,metadata,model database,Grid geoscience computing,spatial information database,maps service and virtual reality.Meanwhile,we developed a series of application systems such as the environment monitoring for the Olympic Games 2008 in Beijing,natural disasters evaluation,digital city,digital archeology,Asia regional aerosol and climate change.The DEPS/CAS displayed the application ability and potential of the Digital Earth in three levels:the global,national and regional. | H.Guo X.Fan C.Wang | 2009 | International Journal of Digital Earth2009，2，1： | 5 |
| 6 | 伊豆—小笠原俯冲带板片的形态与形变研究显示文摘地震层析成像方法为俯冲板片的形态、形变与流变(间接)提供了独特的约束条件。本文利用远震双差P波成像技术对伊豆—小笠原板片的复杂结构进行了非常清晰的成像,结果显示位于26.5°N^28°N之间的地幔过渡带(MTZ)中存在一个板片撕裂。撕裂以北,板片在MTZ发生折叠,在褶皱枢纽的正上方,剪切带内初期的黏性耗散形成了P波衰减区。撕裂以南,在MTZ底部板片发生翻转且平铺于MTZ的底部。2015年小笠原地震(M W约为7.9)的震源深度约为680km,该地震发生在翻转板片的最北端。伊豆—小笠原板片的局部撕裂、剪切和屈曲表明,其经过上地幔和地幔过渡带后仍然保持了较高的黏滞性。 | H.J.Zhang F.Wang R.Myhill H.Guo 刘思青(译) 常利军(校) | 2020 | 世界地震译丛2020，51，5： | 0 |
