| 2 | The research of space-time coupled spectral element method for acoustic wave equations显示文摘A space-time coupled spectral element method based on Chebyshev polynomials is presented for solving time-dependent wave equations.Acoustic propagation problems in1+1,2+1,3+1 dimensions with the Dirichlet boundary conditions are simulated via space-time coupled spectral element method using quadrilateral,hexahedral and tesseractic elements respectively.Space-time coupled spectral element method can obtain high-order precision over time.With the same total number of nodes,higher numerical precision is obtained if the higher-order Chebyshev polynomials in space directions and lower-order Chebyshev polynomials in time direction are adopted.Numerical illustrations have indicated that the space-time algorithm provides higher precision than the semi-discretization.When space-time coupled spectral element method is used,time subdomain-by-subdomain approach is more economical than time domain approach. | GENG Yanhui QIN Guoliang WANG Yang HE Wei | 2016 | Chinese Journal of Acoustics2016,35,1: | 3 |
| 3 | A dynamic analysis of water footprint of Jinghe River basin显示文摘Water footprint in a region is defined as the volume of water needed for the production of goods and services consumed by the local people. Ecosystem services are a kind of important services, so ecological water use is one necessary component in water footprint. Water footprint is divided into green water footprint and blue water footprint but the former one is often ignored. In this paper water footprint includes blue water needed by ag-ricultural irrigation, industrial and domestic water demand, and green water needed by crops, economic forests, livestock products, forestlands and grasslands. The study calculates the footprint of the Jinghe River basin in 1990, 1995, 2000 and 2005 with quarto methods. Results of research show that water footprints reached 164.1×108m3, 175.69×108m3 and 178.45×108m3 respectively in 1990, 1995 and 2000 including that of ecological water use, but reached 77.68×108m3, 94.24×108m3, 92.92×108m3 and 111.36×108m3 respectively excluding that of ecological water use. Green water footprint is much more than blue water footprint; thereby, green water plays an important role in economic development and ecological construction. The dynamic change of water footprints shows that blue water use increases rapidly and that the ecological water use is occupied by economic and domestic water use. The change also shows that water use is transferred from primary industry to secondary industry. In primary industry, it is trans-ferred from crops farming to forestry and animal agriculture. The factors impelling the change include development anticipation on economy, government policies, readjustment of the industrial structure, population growth, the raise of urbanization level, and structural change of consumption, low level of water-saving and poor ability of waste wa-ter treatment. With blue water use per unit, green water use per unit, blue water use structure and green water use structure, we analyzed the difference of the six ecological function districts of the Jinghe River basin. Future ecologi-cal construction may influence on blue water use of District V and District VI at middle and lower reaches. At last some suggestions are given for effective water resource use. | Geng Yanhui Min Qingwen Cheng Shengkui Wan Xin Yang Yanzhao | 2008 | Ecological Economy2008,4,2: | 2 |

| 5 | Synthesis, Characterization and Fluorescence Studies on Complexes of Terbium with Phenylglyoxylic Acid, 2,2-Dipyridine, 1,10-Phenanthroline, Triphenyl Phosphine Oxide显示文摘Three new complexes TbL3dipy(H2O)2, TbL3phen(H2O)2 and TbL2(TPPO)2NO3 have been synthesized (L=phenylglyoxylate ion, dipy=2,2-dipyridine, phen=1,10-phenanthroline, TPPO=Triphenyl phosphine oxide). Elemental analysis, conductivity, IR spectra and 1HNMR spectra studies were performed on them. IR spectra indicate that carboxylate ions in the phenylglyoxylate are coordinated to Tb(Ⅲ) ions as unidentate ligands. In 1HNMR, the signals of hydrogens in phenylglyoxylate shift upfield. The excitation and emission spectra of the three complexes were recorded at room temperature, the excitation spectra show that the optimum excitation wavelengths are 361.0, 359.0 and 367.0 nm, respectively. Four emission bands due to 5D4-7Fj(j=6, 5, 4, 3)transitions were observed for TbL3dipy(H2O)2 (489.0, 545.0, 584.0,620.0 nm) and TbL3phen(H2O)2 (490.0, 544.0, 583.0, 620.0 nm). And under the same conditions, only one emission band due to 5D4-7F5 transition was observed for TbL2(TPPO)2NO3. The emission intensity of TbL3dipy(H2O)2 is the strongest among the three complexes. | Zhang Yanhui Sun Bo Pei Juan Geng Xiaotian Wang Yunyou Yan Jianbo | 2005 | Journal of Rare Earths2005,23,5: | 0 |
