| 1 | Effect of pitch angle on initial stage of a transport airplane ditching显示文摘Airworthiness regulations require that the transport airplane should be proved to ensure the survivability of the ditching for the passengers. The planned ditching of a transport airplane on the calm water is numerically simulated. The effect of pitch angle on the impact characteristics is especially investigated by a subscaled model. The Reynolds-averaged Navier-Stokes (RANS) equations of unsteady compressible flow are solved and the realizable j-e equations are employed to model the turbulence. The transformation of the air-water interface is tracked by volume of fluid (VOF) model. The motion of the rigid body is modeled by dynamic mesh method. The initial ditching stage of the transport airplane is analyzed in detail. The numerical results show that as the pitching angle increases, the maximal normal force decreases and the pitching motion becomes much gentler. The aft fuselage would be sucked down by the water and lead to pitching up, whereas the low horizontal tail prevents this trend. Consequently, the transport aircraft with low horizontal tail should ditch on the water at an angle between 10 and 12 as a recommendation. | Guo Baodong Liu Peiqing Qu Qiulin Wang Jiawen | 2013 | Chinese Journal of Aeronautics2013，26，1： | 18 |

| 3 | New advances in the assessment of tight oil resource in China显示文摘The research on tight oil becomes another hotspot in the field of unconventional oil and gas after the boom of shale gas.The global recoverable resources of tight oil are estimated to be around 47.3×10^(9)t.In recent years,significant progress has been made in the technologies of tight oil exploration and development in North America,thus stimulating the dramatic increase of tight oil production.Meanwhile,China has also acquired remarkable achievements in tight oil exploration.Mature assessment methods have been established for tight oil resources by the US,generally dominated by analogy and statistical methods with their own advantages and disadvantages as well as applicable conditions.In China,improvement of resource evaluation techniques becomes an urgent issue in increasing tight oil reserve and production.This study mainly discusses the resource evaluation methods and resource enrichment characteristics of tight oil.Seven kinds of assessment methods in three categories(i.e.,analogy,statistical and genetic method)and evaluation parameters have been preliminary established,and are specifically applied in the Sichuan,Ordos,Songliao,Junggar,Bohai Bay and other tight oil basins through the newly hierarchical resource abundance analogy method,the estimated ultimate recovery(EUR)analogy method and the small-cell volumetric method.The preliminary evaluation results reveal that China has great potential in tight oil resource,and the geological resources amount to 20×10^(9)t,providing a resource base for large-scale development. | Shejiao Wang Yuanjiang Yu Qiulin Guo Shaoyong Wang Xiaozhi Wu | 2017 | Petroleum Research2017，2，1： | 4 |

| 6 | Generation of spatial atmospheric turbulence field in aircraft motion simulation based on refined similarity hypothesis显示文摘It is necessary to build turbulence model to study the response of aircraft to atmospheric turbulence for high resolution earth observation. The conventional method is on the basis of Dryden’s model with the assumption that individual patches are Gaussian. In this paper,based on Kraichnan’s refined similarity idea,a new 1D atmospheric turbulence model is set up by introducing the energy transfer rate as an intermittency disturbance to a Gaussian process. Our results show that the turbulent fields generated by our new method exhibit an anomalous scaling described by the She-Leveque (SL) formula,which is now well accepted for homogenous and isotropic turbulence. | GUO Hao CHEN JingJing QU QiuLin LIU PeiQing | 2011 | Science China(Technological Sciences)2011，54，1： | 1 |

| 8 | Characteristics of Volcanic Reservoirs and Hydrocarbon Accumulation of Carboniferous System in Junggar Basin, China显示文摘The Carboniferous volcanic reservoirs in Junggar Basin contain rich hydrocarbon resources,implying a great exploration potential,so that they have become a key replacement target for“three-dimensional exploration”.The study on the Carboniferous volcanic reservoirs and their hydrocarbon accumulation elements is significant for clarifying the orientation for exploration.In this paper,based on 37 reserves reports and 3200 reservoir test data,the Carboniferous volcanic reservoirs in Junggar Basin were discussed from the prospective of lithology and lithofacies,physical properties,reservoir types,main controls on hydrocarbon accumulation,and hydrocarbon accumulation patterns.It is found that the Carboniferous in the basin is mostly in the multi-island ocean-volcanic island arc structural-sedimentary environment,so it is geologically eligible for forming in-situ volcanic reservoirs.The volcanic rocks are:(1)mostly distributed along deep and large faults,with the lithology and lithofacies controlled by volcanic architectures;(2)dominantly lava,followed by volcaniclastic lava and volcaniclastic rock;(3)distributed in the periphery of hydrocarbon-generating sag and within the source rocks horizontally,and concentrated in the weathering crust at the top longitudinally,possibly leading to reworked weathering crust reservoir;and(4)liable to form inner reservoirs.The volcanic reservoirs can be concluded into four hydrocarbon accumulation patterns,i.e.,self-generating&self-storing in paleo-uplift and vertical migration,self-generating&self-storing in paleo-uplift and lateral migration,young-generating&old-storing in fault zone and vertical migration,and young-generating&old-storing in paleo-uplift and lateral migration.Future exploration will focus on the effective source rock development and hydrocarbon supply zones and the selfgenerating&self-storing and young-generating&old-storing patterns.The exploration prospects are determined to be the Ludong-Wucaiwan-Baijiahai slope belt and the southern slope belt of the Shaqi uplift(self-generating&self-storing pattern)in eastern Junggar,and the fault and nasal arch zone at the northwestern margin and the nasal arch zone(deep and large structure)in the Luxi area(younggenerating&old-storing pattern)in western Junggar. | Xiaozhi Wu Qiulin Guo Wei Zhang Dengfa He Xuefeng Qi Di Li | 2021 | Journal of Earth Science2021，32，4： | 1 |

| 10 | Mesh model building and migration and accumulation simulation of 3D hydrocarbon carrier system显示文摘Migration and accumulation simulation of oil and gas in carrier systems has always been a difficult subject in the quantitative study of petroleum geology. In view of the fact that the traditional geological modeling technology can not establish the interrelation of carriers in three dimensional space, we have proposed a hybrid-dimensional mesh modeling technology consisting of body(stratum), surfaces(faults and unconformities), lines and points, which provides an important research method for the description of geometry of sand bodies, faults and unconformities, the 3 D geological modeling of complex tectonic areas, and the simulation of hydrocarbon migration and accumulation. Furthermore, we have advanced a 3 D hydrocarbon migration pathway tracking method based on the hybrid-dimensional mesh of the carrier system. The application of this technology in western Luliang Uplift of Junggar Basin shows that the technology can effectively characterize the transport effect of fault planes, unconformities and sand bodies, indicate the hydrocarbon migration pathways, simulate the process of oil accumulation, reservoir adjustment and secondary reservoir formation, predict the hydrocarbon distribution. It is found through the simulation that the areas around the paleo-oil reservoir and covered by migration pathways are favorable sites for oil and gas distribution. | GUO Qiulin LIU Jifeng CHEN Ningsheng WU Xiaozhi REN Hongjia WEI Yanzhao CHEN Gang GONG Deyu YUAN Xuanjun | 2018 | Petroleum Exploration and Development2018，45，6： | 0 |
| 11 | Attractive fixed-point solution study of a shell model for turbulent convection显示文摘Different scaling behaviors, such as Kolmogorov (K41) scaling and Bolgiano and Obukhov (BO) scaling, have been reported in various shell models proposed for turbulent thermal convection. However, two coexistent subranges with K41 and BO scaling are not set up with Bolgiano scale interlaying between the largest scale and the dissipation scale. In this paper, we summarize fixed-point solution study of the Brandenburg model with small perturbation theory by introducing a small disturbance term as the impact of buoyancy. Three groups of fixed-point solutions with different locations of the so-called buoyancy scale, above/below which buoyancy is significant/insignifant. Both theoretical and numerical results show that a modified K41 scaling, instead of K41 and BO coexistent scaling, is set up even though buoyancy may be significant over the scaling range, which suggests that the buoyancy scale is not related exactly to the Bolgiano scale. Thus, a K41 and BO coexistent scaling behavior is not setup for the Brandenburg model. | GUO Hao LI Chao QU QiuLin LIU PeiQing | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，5： | 0 |
| 12 | Electrocatalytic CO_(2) reduction to C_(2)H_(4): From lab to fab显示文摘The global concerns of energy crisis and climate change,primarily caused by carbon dioxide(CO_(2)),are of utmost importance.Recently,the electrocatalytic CO_(2) reduction reaction(CO_(2)RR) to high value-added multi-carbon(C_(2+)) products driven by renewable electricity has emerged as a highly promising solution to alleviate energy shortages and achieve carbon neutrality.Among these C_(2+) products,ethylene(C_(2)H_(4))holds particular importance in the petrochemical industry.Accordingly,this review aims to establish a connection between the fundamentals of electrocatalytic CO_(2) reduction reaction to ethylene(CO_(2)RRto-C_(2)H_(4)) in laboratory-scale research(lab) and its potential applications in industrial-level fabrication(fab).The review begins by summarizing the fundamental aspects,including the design strategies of high-performance Cu-based electrocatalysts and advanced electrolyzer devices.Subsequently,innovative and value-added techniques are presented to address the inherent challenges encountered during the implementations of CO_(2)RR-to-C_(2)H_(4) in industrial scenarios.Additionally,case studies of the technoeconomic analysis of the CO_(2)RR-to-C_(2)H_(4) process are discussed,taking into factors such as costeffectiveness,scalability,and market potential.The review concludes by outlining the perspectives and challenges associated with scaling up the CO_(2)RR-to-C_(2)H_(4) process.The insights presented in this review are expected to make a valuable contribution in advancing the CO_(2)RR-to-C_(2)H_(4) process from lab to fab. | Zeyu Guo Fabao Yang Xiaotong Li Huiwen Zhu Hainam Do Kam Loon Fow Jonathan D.Hirst Tao Wu Qiulin Ye Yaqi Peng Hao Bin Wu Angjian Wu Mengxia Xu | 2024 | Journal of Energy Chemistry2024，90，3： | 0 |
| 13 | Signal enhancement of the laser-induced plasma in the soil mixed with carbon显示文摘An experimental investigation of the carbon concentration effects on the emission intensity has been carried out using laserinduced plasma spectroscopy. The results show that the intensity of Ca II 393.367 nm and 396.847 nm characteristic lines emitted in the sample with the carbon concentration of 25% is about five times larger than that in the pure soil sample. It can be attributed to the high heat transfer coefficient and low ionization potentials of carbon in the system. Using the best experimental condition, quantitative analysis of the trace element of lead is conducted and the detection limit of lead concentration is estimated to be below 0.02%. | ZHANG QiuLin ZHANG JinPing ZHANG Lei LI Xu GUO QingLin FU GuangSheng | 2010 | Chinese Science Bulletin2010，55，4： | 0 |

| 15 | SHTQS: a telephonebased Chinese spoken dialogue system显示文摘SHTQS is an intelligent telephonebased spoken dialogue system providing the information about the best route between two sites in Shanghai. Instead of separated parts of speech decoding and language parsing, a close cooperation is carried out in SHTQS by integrating automatic speech recognizer (ASR), language understanding, dialogue management and speech generator. In such a way, the erroneous analysis and uncertainty happening in the preceding stages would be recovered and determined accurately with highlevel knowledge. Moreover, instead of shallow wordlevel analysis or simply keyword or key phrase matching, a deeper analysis is performed in our system by integrating a robust parser and a semantic interpreter. The robust parser is particularly important for spontaneous speech inputs because most of the inquiry sentences/phrases are illformed. In addition, in designing a mixedinitiative dialogue system, understanding users’ inquiries is essential; however, simply | Mao Jiaju Chen Qiulin Gao Feng Guo Rong Lu Ruzhan | 2005 | Journal of Systems Engineering and Electronics2005，16，4： | 0 |
| 16 | Genomic landscape of mitochondrial DNA insertions in 23 bat genomes:characteristics,loci,phylogeny,and polymorphism显示文摘The transfer of mitochondrial DNA to the nuclear genome gives rise to the nuclear DNA sequences of mitochon-drial origin(NUMTs),considered as a driving force in genome evolution.In this study,NUMTs in 23 bat genomes were investigated and compared systematically.The results showed that NUMTs existed in 22 genomes except for Noctilio leporinus,suggesting that mitochondrial fragment insertion in the nuclear genome was a common event in bat genomes.However,remarkable variations in NUMTs number,cumulative length,and proportion in the nu-clear genome were discovered across bat species.Further orthologous NUMT loci analysis of the Phyllostomidae family indicated that the NUMTs insertion events in bat genomes were homoplasy-free.The NUMTs were mainly inserted into the intergenic regions,particularly,co-localized with repetitive sequences(especially transposable el-ements).However,several NUMTs were inserted into genes,some of which were in the exon region of functional genes.One NUMT in the genome of Pteropus alecto surprisingly matched with cDNA of ATP8B3 that provided evidence of NUMTs with coding function.Phylogenic analysis on NUMTs originating from COXI and COXII loci highlighted 2 clusters of Yinpterochiroptera and Yangochiroptera for Chiroptera.Seven NUMTs from Rhinolophus ferrumequinum were amplified,and the sequencing results confirmed the reliability of the NUMT analysis.One of them was polymorphic for the presence or absence of the NUMT insertion,and each genotype of NUMT loci showed a distinct regional distribution pattern.The information obtained in this study provides novel insights into the NUMT organization and features in bat genomes and establishes a basis for further studying of the evolution of bat species. | Guojun ZHANG Deqi GENG Qiulin GUO Wei LIU Shufen LI Wujun GAO Yongfei WANG Min ZHANG Yilin WANG Yanzhen BU Hongxing NIU | 2022 | Integrative Zoology2022，17，5： | 0 |
| 17 | Detrital Zircon U-Pb Dating of Nanshuangyashan Formation in the Jiamusi Massif, NE China and its Tectonic Implications显示文摘A suite of the fossil-rich marine-land interbedded strata(Nanshuangyashan Formation) is distributed at the eastern margin of the Jiamusi massif in the eastern Heilongjiang Province, NE China. The authors had recently discovered a suite of arkose beneath the marine-land interbedded strata, which overlays unconformably on the Permain granite in the eastern margin of the Jiamusi massif. The LA-ICP-MS zircon U-Pb dating indicate that all detrital zircons from the analysed four arkose samples show the four population ages of >800 Ma, 538-481 Ma, 269-250 Ma and 223-215 Ma. The former three population ages are widely recorded in the Jiamusi-Khanka massif and the Songnen massif. The later group is the minimal age population in the analyzed samples, limiting the sedimentation time of the arkoses occurred after the Late Triassic. At present, the minimal age population is not recorded in the Jiamusi massif, but the granites with the ages of 228-210 Ma are widely distributed in the Songnen-Zhangguangcai Range massif and the Khanka massif. The predominantly Permian zircons are characterized by oscillatory zoning and euhedral shapes, with variable zircon εHf(t) values(-5.5 to +11.2), indicating that they were derived from mixture sources, possibly mixed with components of the Songnen-Zhangguangcai Range massif and the Jiamusi-Khanka massif. These results, combined with regional analyses, indicate that the closing of Mudanjiang ocean and Panthalassa ocean possibly existed from Early Permian to Late Triassic. | CUI Weilong ZENG Zhen ZHANG Xingzhou LIU Zhenghong WANG Shijie PU Jianbin FU Qiulin GUO Ye | 2019 | Acta Geologica Sinica(English Edition)2019，93，5： | 0 |
