| 1 | Vertical migration through faults and hydrocarbon accumulation patterns in deepwater areas of the Qiongdongnan Basin显示文摘In the Qiongdongnan Basin, faults are well developed. Based on the drilling results, the traps controlled two or more faults are oil-rich. However, when only one fault cut through the sand body, there is no sign for hydrocarbon accumulation in the sandstone. In terms of this phenomenon, the principle of reservoir-forming controlled by fault terrace is proposed, i.e., when the single fault activates, because of the incompressibility of pore water, the resistance of pore and the direction of buoyancy, it is impossible for hydrocarbon to accumulate in sandstone. But when there are two or more faults, one of the faults acts as the spillway so the hydrocarbon could fill in the pore of sandstone through other faults. In total five gas bearing structures and four failure traps are considered, as examples to demonstrate our findings. According to this theory, it is well-advised that south steep slope zone of Baodao-Changchang Depression, south gentle slope zone of Lingshui Depression, north steep slope zone of Lingshui Depression, and north steep slope zone of Baodao Depression are the most favorable step-fault zones, which are the main exploration direction in next stage. | WANG Zhenfeng LIU Zhen CAO Shang SUN Zhipeng ZUO Qianmei WANG Yahui HE Weijun | 2014 | Acta Oceanologica Sinica2014，33，12： | 4 |

| 7 | Adsorption of cyclohexene and its dehydrogenation intermediates on nAu/Pt(100)(n = 0, 1, 2) surfaces: A DFT study显示文摘Adsorption of cyclohexene and its dehydrogenation intermediates on the nAu/Pt(100) (n = 0, 1, 2 means clean Pt, one monolayer and two layers of Au covered Pt surfaces, respectively.) has been investigated by self-consistent (GGA-PW91) density functional theory combined with periodic slab model. It is found that on the clean platinum, there are two kinds of favorable adsorption sites, i.e., hollow sites and bridge sites, and the adsorption energy at the hollow site is larger than that at the bridge site. However, on the Au/Pt and 2Au/Pt surfaces, there are three kinds of adsorption sites, and the adsorption energies are alike at both the bridge site and the top site. The magnitude order of the adsorption energies is as follows: clean Pt > Au/Pt > 2Au/Pt. The configurations of cyclohexene molecule have been distorted a little during the geometry optimizations. The lengths of C–M (M = Pt or Au, on the top layer of the slab) bonds are closely related to the corresponding adsorption energies. | Hongyan Ma Wenge Xu Zhenfeng Shang Guichang Wang | 2011 | Journal of Natural Gas Chemistry2011，20，1： | 0 |
| 8 | Fuzzy ta/2 symmetries of straight chain conjugate polyene molecules显示文摘On the basis of our recent studies on the molecular fuzzy point group symmetry,we further probe into the more complicated planar one-dimensional fuzzy periodic molecules-straight chain conjugate polyene.Except for the fuzzy translation transformation,the space transformation of the fuzzy screw rotation and the glide plane will be referred to.In addition,other fuzzy point symmetry transformation lain in the space transformation is discussed.Usually there is a correlation between the fuzzy symmetry characterization caused by the transition of the point symmetry elements and by certain space symmetry transformation.For the molecular orbital,the irreducible representation component is analyzed besides the membership function of the fuzzy symmetry transformation.Also,we inquire into the relativity between some molecular property and the fuzzy symmetry characterization. | LI Yun ZHAO XueZhuang XU XiuFang SHANG ZhenFeng ZHOU Zhen CAI ZunSheng WANG GuiChang LI RuiFang | 2009 | Science China Chemistry2009，52，11： | 0 |
| 9 | Study of the reactivity of radical-molecular addition reaction using density functional theory显示文摘The reactivity of radical-molecular addition reaction was studied in terms of density-functional theory (DFT) and Hartree-Fock theory (HFT). It was found that the DFT method can give more accurate estimated result than the HFT method. The reason might be that the energy of the highest occupied molecular orbital (HOMO) in DFT is not the ionization energy, but rather represents the change in the total energy with respect to the change in occupation number of electrons in the HOMO, consistent with the concept of the transition state. The energy of HOMO in HFT is the ionization energy, which may represent more properly the property of the products and reactants themselves. | WANG Guichang SHANG Zhenfeng YANG Zuoyin PAN Yinming CAI Zunsheng ZHAO Xuezhuang LI Yongwang SUN Yuhan ZHONG Bing | 2001 | Chinese Science Bulletin2001，46，6： | 0 |
