| 1 | Floor heave in the west wing track haulage roadway of the Tingnan Coal Mine: Mechanism and control显示文摘Floor heave of a roadway is a dynamic phenomenon that often happens in the roadways of coal mines. It seriously affects safe production in the coal mine. Floor heave has long been one of the most difficult problems to be resolved during coal mining. An analysis of floor heave in the soft rock surrounding the roadway, and the factors influencing it, allowed the deformation mechanism in the west wing double track haulage roadway of the Tingnan Coal Mine to be deduced. Three types of floor heave are observed there: intumescent floor heave, extrusion and mobility floor heave, and compound floor heave. Control measures are proposed that have been adopted during a recent repair engineering project. Control of the floor heave in the west wing track haulage roadway was demonstrated. The reliability and rationality of a combined support technology including floor anchors, an inverted arch, and anchoring of both sides was verified by mine pressure data and the field observations. Waterproofing measures were also under-taken to assist in the control of floor heave. | Wang Jiong | 2012 | International Journal of Mining Science and Technology2012，22，3： | 18 |
| 2 | Distribution of Pacific-origin water in the region of the Chukchi Plateau in the Arctic Ocean in the summer of 2003显示文摘The upper ocean thermohaline structures in the region of the Chukchi Plateau are analyzed with the hydrographic data collected by the Chinese National Arctic Research Expedition in the summer of 2003. Three types of the Pacific-origin water were found in the upper ocean, Alaska Coastal Water (ACW), summer Bering Sea Water (sBSW) and winter Bering Sea Water (wBSW) are indicated by two maximums temperature and one minimum temperature, piling up from the upper to the lower respectively. The extreme warm ACW with a maximum temperature of 1.62 ℃ was found in the southwestern Canada Basin at a depth of about 50 m. A pathway of the ACW into the basin from its adjacent area did not existed in the expedition period. So it is speculated that the extreme warm feature of the ACW was formed locally in 2003. The relative weak ACW occurred to the east of the Chukchi Cap and in the southern Chukchi Abyssal Plain. The latter one might originate from a warm downwelling that existed in a small canyon at the shelf break of the Chukchi Sea. The sBSW without the ACW was found only at the southwestern flank of the Chukchi Cap. The ACW and the sBSW were not found in the northernmost station at 81°N,which indicates the north boundary of the upper Pacific-origin water in the Canada Basin. The wBSW, which existed in all deep stations,was exactly uniform at temperature. The difference of the core potential temperature of the wBSW in the deep regions is only 0.08 ℃. | SHI Jiuxin CAO Yong ZHAO Jinping GAO Guoping JIAO Yutian LI Shujiang | 2005 | Acta Oceanologica Sinica2005，24，6： | 15 |

| 6 | Observations of the Karimata Strait througflow from December 2007 to November 2008显示文摘In order to quantitatively estimate the volume and property transports between the South China Sea and Indonesian Seas via the Karimata Strait, two trawl-resistant bottom mounts, with ADCPs embedded, were deployed in the strait to measure the velocity profile as part of the South China Sea-Indonesian Seas transport/exchange (SITE) program. A pair of surface and bottom acoustic modems was employed to transfer the measured velocity without recovering the mooring. The advantage and problems of the instruments in this field work are reported and discussed. The field observations confirm the existence of the South China Sea branch of Indonesian throughflow via the Karimata Strait with a stronger southward flow in boreal winter and weaker southward bottom flow in boreal summer, beneath the upper layer northward (reversal) flow. The estimate of the averaged volume, heat and freshwater transports from December 2007 to March 2008 (winter) is (-2.7 ± 1.1) × 10 6 m3/s, (-0.30 ± 0.11) PW, (-0.18 ± 0.07) × 106m3/s and from May to September 2008 (summer) is (1.2 ± 0.6) × 106m3/s, (0.14 ± 0.03) PW, (0.12 ± 0.04) × 106m3/s and for the entire record from December 2007 to October 2008 is (-0.5 ± 1.9) × 10 6 m3/s, (-0.05 ± 0.22) PW, (-0.01 ± 0.15) × 106m3/s (negative/positive represents southward/northward transport), respectively. The existence of southward bottom flow in boreal summer implies that the downward sea surface slope from north to south as found by Fang et al. (2010) for winter is a year-round phenomenon. | SUSANTO R Dwi WEI Zexun ADI Rameyo T FAN Bin LI Shujiang FANG Guohong | 2013 | Acta Oceanologica Sinica2013，32，5： | 9 |
| 7 | An overview of 10-year observation of the South China Sea branch of the Pacific to Indian Ocean throughflow at the Karimata Strait显示文摘Besides the Indonesian throughflow(ITF), the South China Sea throughflow(SCSTF) also contributes to the water transport from the Pacific to the Indian Ocean. However, this South China Sea(SCS) branch at the Karimata Strait is poorly observed until 2007, even though its importance has been suggested by numerical studies for decades. In this paper, we review the nearly 10-year field measurement in the Karimata Strait by the execution of the projects of 'SCS-Indonesian Seas Transport/Exchange(SITE) and Impacts on Seasonal Fish Migration' and 'The Transport, Internal Waves and Mixing in the Indonesian Throughflow regions(TIMIT) and Impacts on Marine Ecosystem', which extend the observations from the western Indonesian seas to the east to include the main channels of the ITF, is introduced. Some major achievements from these projects are summarized. | Zexun Wei Shujiang Li R.Dwi Susanto Yonggang Wang Bin Fan Tengfei Xu Budi Sulistiyo T.Rameyo Adi Agus Setiawan A.Kuswardani Guohong Fang | 2019 | Acta Oceanologica Sinica2019，38，4： | 9 |
| 8 | Characteristics of the lower layer of sandstorms in the Minqin desert-oasis zone显示文摘By measuring the sand-dust flux,vertical deposition,and the wind velocity throughout 19 sandstorms in the Minqin region,we quantitatively analyzed the horizontal distribution and vertical variation in sandstorm characteristics under different land cover conditions.The effect of different land cover on mitigating sandstorms was also investigated.The results indicated that,in the surface layer ranging from 0-50 m,the intensity of sand-dust horizontal flux and concentration of sand-dust decreased with the increase of the height in the desert and the edge of oasis,whereas the two physical quantities increased slightly with the increase of the height in the oasis.The two physical quantities obey power function well under all three cover conditions.Moreover,in the desert and at the edge of oasis,the sand-dust vertical deposition decreased with the increase of the height.But a partial unimodal distribution at the oasis site and the maximum deposition occurred at the height of 9 m,which corresponds to the middle height of farmland protection forest.The annual flux that passed through a section of 1 m in width and 50 m in height was 9169 kg in the desert,5318 kg at the edge of oasis,and 2345 kg in the oasis.And the annual fluxes at the edge of oasis and in the oasis are 42% and 74% less,respectively,than that in the desert.This implies that the wind break forest significantly reduced the intensity of sandstorms. | ZHAO Ming ZHAN KeJie YANG ZiHui FANG ErTian QIU GuoYu WANG QiangQiang ZHANG YinChang GUO ShuJiang LI AiDe ZHANG JingChun | 2011 | Science China Earth Sciences2011，54，5： | 8 |
| 9 | Highly Stretchable and Transparent Ionic Conductor with Novel Hydrophobicity and Extreme-Temperature Tolerance显示文摘Highly stretchable and transparent ionic conducting materials have enabled new concepts of electronic devices denoted as iontronics,with a distinguishable working mechanism and performances from the conventional electronics.However,the existing ionic conducting materials can hardly bear the humidity and temperature change of our daily life,which has greatly hindered the development and real-world application of iontronics.Herein,we design an ion gel possessing unique traits of hydrophobicity,humidity insensitivity,wide working temperature range(exceeding 100℃,and the range covered our daily life temperature),high conductivity(10^(-3)~10^(-5) S/cm),extensive stretchability,and high transparency,which is among the bestperforming ionic conductors ever developed for flexible iontronics.Several ion gel-based iontronics have been demonstrated,including large-deformation sensors,electroluminescent devices,and ionic cables,which can serve for a long time under harsh conditions.The designed material opens new potential for the real-world application progress of iontronics. | Lei Shi Kun Jia Yiyang Gao Hua Yang Yaming Ma Shiyao Lu Guoxin Gao Huaitian Bu Tongqing Lu Shujiang Ding | 2020 | Research2020，，1： | 7 |
| 10 | A preliminary analysis of fishery resource exhaustion in the context of biodiversity decline显示文摘Marine biodiversity in almost all oceans is being threatened at the genetic, species, and ecosystem levels. The marine ecosystem is being degraded and the extinction rate of marine organisms has accelerated. In this paper, the potential causes of fishery resource exhaustion in the East China Sea are analyzed, including the change in the stoichiometric composition of seawater with regard to the concentrations of N and P, toxic effects of marine pollution, marine habitat destruction, increased seawater temperatures caused by climate warming, ocean acidification, pressure from overfishing, and the spread of marine pathogenic bacteria. It is believed that the factors mentioned above have significant impact on the exhaustion of fishery resources in the East China Sea. However, considering the cumulative, synergistic, and superimposed effects as well as the amplification effects resulting from their interactions, the actual risk of ecological extinction of marine organisms might be even more severe than that previously estimated. Hence, ecosystem management and research focused on a single risk factor or influencing factor is not enough to prevent marine ecosystem degradation and fishery resource exhaustion. A comprehensive, systematic, effective, and ecosystem-based management policy is imperative for healthy and sustainable fishery development in the East China Sea. | ZHAO ShuJiang Lü BaoQiang LI RuWei ZHU AiYi WU ChangWen | 2016 | Science China Earth Sciences2016，59，2： | 6 |
| 11 | High-efficiency quantum steganography based on the tensor product of Bell states显示文摘In this paper,we first propose a hidden rule among the secure message,the initial tensor product of two Bell states and the final tensor product when respectively applying local unitary transformations to the first particle of the two initial Bell states,and then present a high-efficiency quantum steganography protocol under the control of the hidden rule.In the proposed quantum steganography scheme,a hidden channel is established to transfer a secret message within any quantum secure direct communication(QSDC) scheme that is based on 2-level quantum states and unitary transformations.The secret message hiding/unhiding process is linked with the QSDC process only by unitary transformations.To accurately describe the capacity of a steganography scheme,a quantitative measure,named embedding efficiency,is introduced in this paper.The performance analysis shows that the proposed steganography scheme achieves a high efficiency as well as a good imperceptibility.Moreover,it is shown that this scheme can resist all serious attacks including the intercept-resend attack,measurement-resend attack,auxiliary particle attack and even the Denial of Service attack.To improve the efficiency of the proposed scheme,the hidden rule is extended based on the tensor product of multiple Bell states. | XU ShuJiang CHEN XiuBo NIU XinXin YANG YiXian | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，9： | 6 |
| 12 | Seasonal variation of water transport through the Karimata Strait显示文摘Four trawl-resistant bottom mounts, with acoustic Doppler current profilers(ADCPs) embedded, were deployed in the Karimata Strait from November 2008 to June 2015 as part of the South China Sea-Indonesian Seas Transport/Exchange and Impact on Seasonal Fish Migration(SITE) Program, to estimate the volume and property transport between the South China Sea and Indonesian seas via the strait. The observed current data reveal that the volume transport through the Karimata Strait exhibits significant seasonal variation. The winteraveraged(from December to February) transport is –1.99 Sv(1 Sv=1×10~6 m^3/s), while in the boreal summer(from June to August), the average transport is 0.69 Sv. Moreover, the average transport from January 2009 to December2014 is –0.74 Sv(the positive/negative value indicates northward/southward transport). May and September are the transition period. In May, the currents in the Karimata Strait turn northward, consistent with the local monsoon. In September, the southeasterly trade wind is still present over the strait, driving surface water northward, whereas the bottom flow reverses direction, possibly because of the pressure gradient across the strait from north to south. | Yan Wang Tengfei Xu Shujiang Li R.Dwi Susanto Teguh Agustiadi Mukti Trenggono Wei Tan Zexun Wei | 2019 | Acta Oceanologica Sinica2019，38，4： | 5 |
| 13 | A double-halocline structure in the Canada Basin of the Arctic Ocean显示文摘A year-round halocline is a particular hydrographic structure in the upper Arctic Ocean. On the basis of an analysis of the hydrographic data collected in the Arctic Ocean, it is found that a double-halocline structure exists in the upper layer of the southern Canada Basin, which is absolutely different from the Cold Halocline Layer (CHL) in the Eurasian Basin. The Pacific-origin water is the primary factor in the formation of the double-halocline structure. The upper halocline lies between the summer modification and the winter modification of the Pacific-origin water while the lower halocline results from the Pacific-origin water overlying upon the Atlantic-origin water. Both haloclines are all the year-round although seasonal and interannual variations have been detected in the historical data. | SHI Jiuxin ZHAO Jinping LI Shujiang CAO Yong QU Ping | 2005 | Acta Oceanologica Sinica2005，24，6： | 5 |

| 15 | Phase boundary engineering of metal-organic-framework-derived carbonaceous nickel selenides for sodium-ion batteries显示文摘Nano Research volume 13,pages2289–2298(2020)Cite this article 347 Accesses 1 Altmetric Metrics details Abstract Sodium-ion batteries(SIBs)are promising power sources due to the low cost and abundance of battery-grade sodium resources,while practical SIBs suffer from intrinsically sluggish diffusion kinetics and severe volume changes of electrode materials.Metal-organic framework(MOFs)derived carbonaceous metal compound offer promising applications in electrode materials due to their tailorable composition,nanostructure,chemical and physical properties.Here,we fabricated hierarchical MOF-derived carbonaceous nickel selenides with bi-phase composition for enhanced sodium storage capability.As MOF formation time increases,the pyrolyzed and selenized products gradually transform from a single-phase Ni3Se4 into bi-phase NiSex then single-phase NiSe2,with concomitant morphological evolution from solid spheres into hierarchical urchin-like yolk-shell structures.As SIBs anodes,bi-phase NiSex@C/CNT-10h(10 h of hydrothermal synthesis time)exhibits a high specific capacity of 387.1 mAh/g at 0.1 A/g,long cycling stability of 306.3 mAh/g at a moderately high current density of 1 A/g after 2,000 cycles.Computational simulation further proves the lattice mismatch at the phase boundary facilitates more interstitial space for sodium storage.Our understanding of the phase boundary engineering of transformed MOFs and their morphological evolution is conducive to fabricate novel composites/hybrids for applications in batteries,catalysis,sensors,and environmental remediation. | Shiyao Lu Hu Wu Jingwei Hou Limin Liu Jiao Li Chris J.Harris Cheng-Yen Lao Yuzheng Guo Kai Xi Shujiang Ding Guoxin Gao Anthony K.Cheetham R.Vasant Kumar | 2020 | Nano Research2020，13，8： | 4 |
| 16 | Research on Coupling Relationship between Social Economy and Ecological Environment in Jinghe County of Aiby Lake Basin,Xinjiang显示文摘Based on the theory of sustainable development,using the theory and method of coupling relationship,the main city of Aiby Lake basin——Jinghe County in Xinjiang is selected. Based on the analyses of natural condition,population growth,land use type and ecological environment,the comprehensive evaluation index systems of socio-economic development level and eco-environment quality in Jinghe County are constructed. Using principal component analysis,a comprehensive evaluation of socio-economic development level and ecological environment quality in Jinghe County is conducted by combining with Excel. Their coupling relationship is studied,and quantitative coordination degree between social economy and ecological environment in Jinghe County is obtained. The results show that in recent 50 years,socio-economic development level in Jinghe County is rising,but the ecological environment quality is falling. Their coupling degree C changes during [- 1. 260, + 0. 482],in other words,their coupling relationship is changing between ' reluctant coordination' and ' not coordination'. After entering into the 21 stcentury,their coupling relationship is basically ' reluctant coordination'. On this basis,the existing problems in the process of sustainable development in Jinghe County are analyzed,and the suggestions about promoting coordinated development between social economy and ecological environment are put forward. | Lai Fengbing Sun Hu Chen Shujiang Ren Shuang | 2014 | Meteorological and Environmental Research2014，5，11： | 4 |
| 17 | Network traffic prediction method based on improved ABC algorithm optimized EM-ELM显示文摘In order to overcome the poor generalization ability and low accuracy of traditional network traffic prediction methods,a prediction method based on improved artificial bee colony( ABC) algorithm optimized error minimized extreme learning machine( EM-ELM) is proposed. EM-ELM has good generalization ability. But many useless neurons in EM-ELM have little influences on the final network output,and reduce the efficiency of the algorithm.Based on the EM-ELM,an improved ABC algorithm is introduced to optimize the parameters of the hidden layer nodes,decrease the number of useless neurons. Network complexity is reduced. The efficiency of the algorithm is improved. The stability and convergence property of the proposed prediction method are proved. The proposed prediction method is used in the prediction of network traffic. In the simulation,the actual collected network traffic is used as the research object. Compared with other prediction methods,the simulation results show that the proposed prediction method reduces the training time of the prediction model,decreases the number of hidden layer nodes. The proposed prediction method has higher prediction accuracy and reliable performance. At the same time,the performance indicators are improved. | Tian Zhongda Li Shujiang Wang Yanhong Wang Xiangdong | 2018 | The Journal of China Universities of Posts and Telecommunications2018，25，3： | 3 |
| 18 | Dynamic analysis and evaluation of Xinjiang forest resources:based on RS and GIS显示文摘The forest resources in Xinjiang were surveyed and analyzed based on RS and GIS. Satellite data interpretation was adopted to obtain the general situation of Xinjiang forest resources in assistance with the sampling method and on-the-spot investigations. Based on GIS, related data obtained from satellite remote sensing in 1996 and 2001 were studied through contrastive analysis. Moreover, the dynamic variation of Xinjiang forest resources was studied in an all-around way. In the past five years, the areas of the forestland, woodland, sparse woodland, nursery garden and the land usable for forestry in Xinjiang kept growing, moreover, the forest cover rate and the total standing stock volume increased correspondingly, showing that the wooded area and the amount of growing stock in Xinjiang were increasing. The forestland area in Xinjiang went up to 17,837 km2 from 17,331 km2, with an annual average increase of 101 km2. Accordingly, the forest vegetation came to 1.08% from 1.05%, up 0.03 percentage point; the total standing stock volume went up to 289,985,200 m3 from 262,416,000 m3, a total increase of 27,569,200 m3, an annual average increase of 5,514,000 m3 and an annual average net growth rate of 2.00%. The analysis results showed that the forest resources in Xinjiang were increasing on the whole, however, there remained some problems, such as the sparse natural forests, low forest cover rate, imbalanced wood age structure, and mono tree species composition, etc. | LI Hu WANG Xiaofen CHEN Shujiang HOU Ping | 2005 | Journal of Geographical Sciences2005，15，3： | 3 |
