3Mineralogy and crystal structure determination of Mg-fillowite显示文摘Accurate crystal structure determination of complex phosphate Mg-fillowite ? Na2Ca(Mn4Mg2Fe)7[PO4]6 has been finished. Mg-fillowite occurs in muscovite-pegmatite in the Altay area, Xinjiang, China. It is of the trigonal lattice, with space group R-3, unit cell a=1.5143(3) nm, c=4.3191(2) nm, V=8.5736 nm3, Z = 18. The R-factor of the determination accuracy is R (I > 2σ ( I )) = 0.0776. The cationic polyhedra consist of two kinds of structural units: compound col- umn and screw column. In three-dimensional space, they are linked with each other through corner sharing or edge sharing to build the entire structure. There are 45 atoms in an asymmetric unit and 720 atoms in a unit cell. In terms of types and connection manners of the coordination polyhedra, the degree of complicity is rarely seen in all mineral crystal structures. Study of such a structure is significant for the classification of phosphate and the building rule of coordination polyhedra in a complex crystal structure.MA Zhesheng 1 , SHI Nicheng 1 & YE Danian 2 1.

5The planimetric unfold method of fullerene cage structure显示文摘Two kinds of planimetric diagrams, which consist of the boat form F6 and F5, the storm petrel form F6and F5, respectively, were proposed to express the geometric structure of fullerene cage in this study. There are two chief advantages using the diagrams: ( i) the spatial symmetrical characteristic of fullerene cage is not destroyed; (ii) the coordination forms of F5 and F6 in the structure can be clearly expressed. This work has laid the foundation for studying the structural geometry of fullerene cage and its quantum chemistry and property.YE Danian Al Desheng HE Wei XU Wendong 2000Chinese Science Bulletin2000,45,20:0
6Observation system simulation experiments using an ensemble-based method in the northeastern South China Sea显示文摘An ensemble-based method for the observation system simulation experiment(OSSE)is employed to design optimal observation stations and assess the present observation stations in the northeastern South China Sea(SCS).We employed the 20-year(1992-2012)sea surface height(SSH)data to design an array to monitor the intraseasonal to interannual variability.The results show that the most key region was found located at the northwest of Luzon Island(LI)where the energetic Luzon cyclonic gyre(LCG)occurs;other key regions include the edge of the LCG,the northwest of the Luzon Strait(LS),and the southwest of Taiwan,China.By contrast,we found that the present observation stations might oversample at the northwest of the LS and undersample at the northwest of LI.In addition,the optimal stations perform better in a larger area than the present stations.In vertical direction,the key layer is located within the upper 200-m depth,of which the surface and subsurface layers are most valuable to the observing system.GENG Wu CHENG Feng XIE Qiang ZOU Xiaoli HE Weihong WANG Zhaozheng SHU Yeqiang CHEN Gengxin LIU Danian YE Dong WANG Ruiwen LIU Chuanyu 2020Journal of Oceanology and Limnology2020,38,6:0
7Theoretical calculation of the coefficients of thermal expansion for various AB type halides显示文摘By analyzing the relationship between thermal expansion coefficients of AB type halides and their crystal chemistry properties, an empirical formula for theoretical calculation of their thermal expansion coefficients is drawn. The formula has a simple form and a high accuracy with an average error of 2 4%.Zhang Zhenyu Ye Danian Liu Weiling 1998Chinese Science Bulletin1998,43,4:0
8Variation of the grand mean value of Si-O distances in metamorphic reactions显示文摘The grand mean values of Si-O distances in both the left and the right sides of 33 metamorphic reaction equations have been calculated on the basis of data of single crystal structural refinement analysis. The results showed that the grand mean value of Si-O distances tends to decrease at high temperature, whereas that tends to increase at high pressure during a metamorphic reaction.Danian Ye Zhe Li Wei He 2001Chinese Science Bulletin2001,46,8:0
9Symmetrical Distributions of Cities and Urbanization Trends in China显示文摘As products of urbanization,cities are focal points for social and economic interaction.Though China is an ancient civilization,only recently has the urban population surpassed that in rural areas.During the last three decades,unprecedented urbanization has reshaped China's geographical,social,economic and cultural landscapes.Among the social-economic transformations having occurred in China in recent history,urbanization is probably the most impressive and dynamic process;it has changed daily life of Chinese population and profoundly impacted the regional and global economy.YE Danian HE Wei LI Zhe XU Wendong 2012Journal of Geographical Sciences2012,22,2:0
