| 1 | The application of large volume airgun sources to the onshore-offshore seismic surveys: implication of the experimental results in northern South China Sea显示文摘Onshore-offshore seismic experiments were carried out for the first time in northern South China Sea using large volume airgun sources at sea and seismic stations on land. The experimental results indicate that seismic signals from the new airgun array of R/V Shiyan 2 can be detected as far as 255 km. The signal effective area reaches nearly 50000 km2, which covers Hong Kong and Pearl River Delta. Compared with the old airgun array, the signal amplitude, propagation distance and effective area of the new airgun array have been increased notably, which demonstrates that the upgrade of the airgun source was successful. Comparisons with previous experimental results in other regions show that the shooting effect of the new airgun array is similar to those best airgun sources in the world. Especially, it is a new breakthrough in using the permanent seismic stations onshore to record long distance airgun signals offshore, which has great significance to the realization of the 'seismic radar' concept and the 3D seismic surveys of crustal structure in coastal areas. | QIU XueLin CHEN Yong ZHU RiXiang XU HuiLong SHI XiaoBin YE ChunMing ZHAO MingHui XIA ShaoHong | 2007 | Chinese Science Bulletin2007，52，4： | 27 |
| 2 | OCEAN BOTTOM SEISMOMETER AND ONSHOREOFFSHORE SEISMIC EXPERIMENT IN NORTHEASTERN SOUTH CHINA SEA显示文摘Three-component Ocean Bottom Seismometers, portable land stations and marine air gun seismic sources were used to carry out an onshore-offshore deep seismic profile in northeastern South China Sea. This profile, orientated in NNW-SSE, was as long as 500 km and perpendicular to the strike of regional tectonics. The offshore data were processed in Taiwan Ocean University using a number of available software and the onshore data were analyzed in South China Sea Institute of Oceanology by new-written programs and public software. Preliminary results show that the seismic data are in good quality and contain rich information of deep structure. Seismic phases, e.g. Pg, PmP and Pn, are identified in the offset range 5~220 kin, which will provide an important dataset for the deep crustal structure and oil-gas basin evolution studies of this region. | QIU Xuelin ZHAO Minghui YE Chunming WANG Tankai WANG Ping ZHANG Yixiang XIA Kanyuan LEE Chaoshing | 2004 | Geotectonica et Metallogenia2004，28，1： | 8 |
| 3 | Selective hydrocracking of light cycle oil into high-octane gasoline over bi-functional catalysts显示文摘Light cycle oil(LCO) with high content of poly-aromatics was difficult to upgrade and convert,which had hindered upgrading fuel quality to meet with the standard of automotive diesel for the purpose of sustainable development.The hydrocracking behaviors of typical aromatics in LCO of naphthalene and tetralin were investigated over NiMo and CoMo catalysts.Several characterization methods including N2-adsoprtion and desorption,ammonia temperature-programmed desorption(NH3-TPD),Pyridine infrared spectroscopy(Py-IR),CO infrared spectroscopy(CO-IR),Raman and X-ray photoelectron spectroscopy(XPS) were applied to determine the properties of different catalysts.The results showed that CoMo catalyst with high concentration of S-edges could hydrosaturate more naphthalene to tetralin but exhibit lower yield of high-value light aromatics(carbon numbers less than 10) than NiMo catalyst.NiMo catalyst with high concentration of Mo-edges also presented a higher selectivity of converting naphthalene into cyclanes than CoMo catalyst.Subsequently,the naphthalene and LCO hydrocracking performances were also investigated over different catalysts systems.The activity evaluation and kinetic analysis results showed that the naphthalene hydrocracking conversion and the yield of light aromatics for CoMo-AY/NiMo-AY grading catalysts were higher than NiMo-AY/CoMo-AY grading catalysts at same condition.A stepwise reaction principle was proposed to explain the high efficiency of CoMo-AY/NiMoAY grading catalysts.Finally,the LCO hydrocracking evaluation results confirmed that CoMo-AY/NiMoAY catalysts grading system with low carbon deposition and high stability could remain high percentage of active phases,which was more efficient to convert LCO to high-octane gasoline. | Zhengkai Cao Xia Zhang Chunming Xu Xinlu Huang Ziming Wu Chong Peng Aijun Duan | 2021 | Journal of Energy Chemistry2021，30，1： | 3 |
| 4 | Wuacanthus(Acanthaceae),a new Chinese endemic genus segregated from Justicia(Acanthaceae)显示文摘A new genus,Wuacanthus Y.F.Deng,N.H.Xia&H.Peng(Acanthaceae),is described from the Hengduan Mountains,China.Wuacanthus is based on Wuacanthus microdontus(W.W.Sm.)Y.F.Deng,N.H.Xia&H.Peng,originally published in Justicia and then moved to Mananthes.The new genus is characterized by its shrub habit,strongly 2-lipped corolla,the 2-lobed upper lip,3-lobed lower lip,2 stamens,bithecous anthers,parallel thecae with two spurs at the base,2 ovules in each locule,and the 4-seeded capsule.Phylogenetic analyses show that the new genus belongs to the Pseuderanthemum lineage in tribe Justicieae.Wuacanthus is closely related to Pseuderanthemum but differs from the latter by its shorter corolla tube and two minute spurs at the base of each anther-theca.W.microdontus is assessed with the status EN B2ab(iii)based on the IUCN Red List Categories and Criteria. | Yunfei Deng Chunming Gao Nianhe Xia Hua Peng | 2016 | Plant Diversity2016，38，6： | 3 |

| 6 | Effect of single Si_(1−x)C_(x)coating and compound coatings on the thermal conductivity and corrosion resistance of Mg-3Sn alloy显示文摘A single Si_(1−x)C_(x)coating and compound coatings were deposited on Mg-3Sn matrix alloy by magnetron sputtering method.Compound coatings included Mg or Mg/AlTi intermediates between Mg-3Sn substrate and Si_(1−x)C_(x)coating.The thermal conductivity of the Mg-3Sn alloy after coating was enhanced at room temperature.The results showed that the Mg-3Sn alloy coated with Mg/AlTi/Si_(1−x)C_(x)displayed higher thermal conductivity,its thermal conductivity after corrosion was 90.1 W/(m K)and 108.4 W/(m K)at 25℃and 100℃,respectively.Meanwhile,it was revealed that the Mg/Si_(1−x)C_(x)and Mg/AlTi/Si_(1−x)C_(x)compound coatings had nobler Ecorr and much lower i_(corr),higher Rp,compared with the bare Mg-3Sn and Mg-3Sn/Si_(1−x)C_(x)system,and improved the corrosion resistance of the magnesium substrate. | Chunming Wang Sufen Xiao Yungui Chen Xia Liu | 2015 | Journal of Magnesium and Alloys2015，3，1： | 2 |

| 20 | Chloroaluminate ionic liquid catalyzed isomerization of n-pentane in the presence of product distribution improver显示文摘The ionic liquid Et3NHCl-2AlCl3 can catalyze the isomerization of n-pentane.This paper investigates the ionic liquid catalyzed isomerization performance of n-pentane with several product distribution improvers in an autoclave.The product distribution of n-pentane isomerization could be improved by such improvers as benzene,cyclohexane,and methyl cyclohexane at the expense of conversion of n-pentane.The optimal product distribution improver was determined to be cyclohexane.The yield of isomerate and the selectivity of liquid isoalkanes increased,whereas the conversion of n-pentane decreased,with increasing cyclohexane amount.At the same conversion of n-pentane,the research octane number(RON) of liquid product,with cyclohexane amount of 0.5 wt%,was about 1.3 higher than that without cyclohexane.At the same reaction conditions,the presence of cyclohexane enhanced the yield of isomerate,the selectivity of liquid isoalkanes,and the RON of the liquid product,but reduced the conversion of n-pentane. | Xia Rong'an Zhang Rui Meng Xianghai Liu Zhichang Meng Jiaying Xu Chunming | 2011 | Petroleum Science2011，8，2： | 1 |
