| 1 | Arctic oscillation and the antarcic oscillation modes in the atmospheric stratosphere显示文摘On the basis of the EOF analysis of global geopotential height anomaly (GHA) field at 10 hPa level, the arctic oscillation (AO) and the means antarctic oscillation (AAO) can be detected more obviously at the upper level of atmosphere than the AO or the AAO in surface layer. Unlike the hemisphere pattern of the AO and the AAO in the surface lager given by previous authors, the AO or the AAO in the stratosphere has its global features. The zonal oscillations-the Southern Oscillation (SO) and the north oscillation (NO) in atmospheric surface layer become less clear in the upper air. The first mode (AO mode, abbreviated to AOM hereafter) and the second mode (AAO mode, abbreviated to AAOM hereafter) respectively have 41.47% and 27.04% of the total variance contribution. The cumulative variance contribution of the first two modes reaches 68.51%. These two modes are the main components for the interdecadal or decadal oscillation in the stratosphere. In addition, there still exist two kinds of oscillation patterns with less probability, namely, the symmetric pattern at mid-high latitudes in the Southern Hemisphere and the asymmetric pattern. Spectral analysis shows that the AOM and the AAOM all have a spectral peak for 22 a period, being consistent with the periodic variations of the solar magnetic field, and a peak for 11 a period, being consistent with the period of the numbers of sunspots. Step filter analysis shows that the influencing factor for the upper atmospheric oscillation is the solar activity. The fluctuation of the solar magnetic field is the more influencing factor than the variation of the sunspot number. | QU Weizheng HUANG Fei ZHAO Jinping YANG Liang HE Hui DENG Shenggui CAO Yong | 2005 | Acta Oceanologica Sinica2005，24，6： | 4 |

| 7 | Theoretical study of partial oxidation of ethylene by vanadium trioxide cluster cation显示文摘Density functional theory (DFT) study of reaction between vanadium trioxide cluster cation (VO3+) and ethylene (C2H4) to yield VO2+ + CH3CHO (acetaldehyde) and VO2CH2+ + HCHO (formaldehyde) is carried out. Structures of all reactants, products, intermediates, and transition state in the reaction have been optimized and characterized. The results show unexpected barriers in the reaction due to the existence of a η2-O2 moiety in the ground state structure of VO3+. The initial reaction steps combining ethylene adsorption, C=C activation and O-O cleavage are proposed as rate limiting processes. Comparison of reactions of VO3+ + C2H4 with VO3 + C2H4 and VO2+ + C2H4 in the previous studies is made in detail. The results of this work may shed light on the understanding of C=C bond cleavage in related heterogeneous catalysis. | WANG ZheChen DING XunLei MA YanPing CAO Hai WU XiaoNan ZHAO YanXia HE ShengGui | 2009 | Chinese Science Bulletin2009，54，16： | 0 |
| 8 | Lattice Effect on the Transport Properties in Double Doped La_(2/3)(Ca_(1-x)Sr_x)_(1/3)MnO_3 Films显示文摘The transport properties in the La2/3(Ca1-xSrx)1/3MnO3 (x=0, 1/3, 2/3) films prepared using the RF magnetronsputtering method were investigated. The effect of the Ca, Sr double-doping at the A position in the La2/3A1/3MnO3on the structure of the targets and transport of the films has been studied. With the increase of x, the structures of thetargets transform from the rhombohedral phase to the cubic phase; the metal-insulator phase transition temperature(TP) of the films increases; and the corresponding peak resistivity decreases. All the phenomena can be qualitativelyexplained by the lattice effect. | Kexin JIN Changle CHEN Shenggui ZHAO Yongcang WANG Zhoumo SONG Xiao YUAN | 2005 | Journal of Materials Science & Technology2005，21，6： | 0 |
