| 1 | Backfilling technology and strata behaviors in fully mechanized coal mining working face显示文摘Based on the principle of fully mechanized backfilling and coal mining technology and combined with the Xingtai Coal Mine conditions,we mainly optimized the coal mining equipment and adjusted the coal mining method in the Xingtai Coal Mine 7606 working face for implementation this technology.Firstly,we define the practical backfilling process as the ''(from backfilling scraper conveyor's) head to tail backfilling,step by step swinging up of the tamping arm,gradual compacting,moving formed backfilling scraper conveyor when the second tamping arm cannot pass and connecting the immediate roof by back material push front material movement''.Meanwhile,the stress changes of backfill body in coal mined out area was monitored by stress sensors,and the roof caving law was analyzed by monitoring the dynamic subsidence of à210 west roadway of this face.The site tests results show that using this new backfilling and coal mining integrated technology,the production capacity in the 7606 working face can reach to 283,000 ton a year,and 282,000 ton of solid materials(waste and fly ash) is backfilled,which meets the needs of high production and efficiency.The goaf was compactly backfilled with solid material and the strata behavior was quite desirable,with an actual maximum vertical stress of the backfill body of 5.5 MPa.Backfill body control the movement of overburden within a certain range,and there is no collapses of major areas in the overlying strata upon backfilled gob.The maximum subsidence and speed were 231 mm and 15.75 mm/d respectively,which proved the practical significance of this integrated technology. | Zhang Qiang Zhang Jixiong Huang Yanli Ju Feng | 2012 | International Journal of Mining Science and Technology2012，22，2： | 55 |
| 2 | Strata movement controlling effect of waste and fly ash backfillings in fully mechanized coal mining with backfilling face显示文摘A fully mechanized coal mining with backfilling (FMCMB) provides advantages of safety and efficiency for coal mining under buildings, railways, and water bodies. According to the field geological conditions, we analyzed the controlling effect of strata movement by the waste and fly ash backfilling in FMCMB face. Based on the key strata theory, we established the equivalent mining thickness model, and analyzed the action of the bulk factor of backfilling body to the equivalent mining thickness. In addition, we numerically simulated the controlling function of the strata movement by backfilling bodies with differ- ent strength. And the numerical simulation result show that the deformation of stratum and the subsi- dence of surface can be controlled by FMCMB. The result provides references to the effective execution of fully mechanized coal mining with solid waste backfilling in goaf. | Zhang Jixiong Zhang Qiang Huang Yanli Liu Jinwei Zhou Nan Zan Dongfeng | 2011 | Mining Science and Technology2011，21，5： | 27 |
| 3 | An investigation of surface deformation after fully mechanized,solid back fill mining显示文摘The surface deformation after fully mechanized back filling mining was analyzed.The surface deformation for different backfill materials was predicted by an equivalent mining height model and numerical simulations.The results suggest that:(1) As the elastic modulus,E,of the backfill material increases the surface subsidence decreases.The rate of subsidence decrease drops after E is larger than 5 GPa;(2) Fully mechanized back fill mining technology can effectively control surface deformation.The resulting surface deformation is within the specification grade I,which means surface maintenance is not needed.A site survey showed that the equivalent mining height model is capable of predicting and analyzing surface deformation and that the model is conservative enough for engineering safety.Finally,the significance of establishing a complete error correction system based on error analysis and correction is discussed. | Li Jian Zhang Jixiong Huang Yanli Zhang Qiang Xu Junming | 2012 | International Journal of Mining Science and Technology2012，22，4： | 23 |

| 5 | Determination of both jasmonic acid and methyl jasmonate in plant samples by liquid chromatography tandem mass spectrometry显示文摘An efficient method for the simultaneous extraction and quantification of both jasmonic acid(JA)and methyl jasmonate(MeJA) from a single plant sample was developed.Plant tissues were firstly extracted by using 100%cold methanol,then the Sep-pak C18 solid-phase extraction(SPE)cartridges were adopted for the purification of sample extract,and finally JA and MeJA were determined by the liquid chromatography tandem mass spectrometry(LC-MS-MS)system.It was found that the accuracy was improved by using the extra standard for the estimation and correction of JA and MeJA losses in the extraction and purification process.The detection limits for JA and MeJA were 0.03 and 0.075 ng mL-1,respectively,and the average recovery rate of JA and MeJA was 92.48%and 94.30%.The method was found to be reproducible and selective,yielding well isolated and easily detectable peaks for both JA and MeJA and simplifying the time-consuming extraction and purification.High-performance liquid chromatography(HPLC)system was employed as the control detection method for the LC-MS-MS system.The two systems were compared in their specificity and accuracy. | LIU Xia YANG YanLi LIN WanHuang TONG JianHua HUANG ZhiGang XIAO LangTao | 2010 | Chinese Science Bulletin2010，55，21： | 10 |

| 7 | Clinical applications of MARSALA for preimplantation genetic diagnosis of spinal muscular atrophy显示文摘Conventional PCR methods combined with linkage analysis based on short tandem repeats(STRs) or Karyomapping with single nucleotide polymorphism(SNP) arrays, have been applied to preimplantation genetic diagnosis(PGD) for spinal muscular atrophy(SMA), an autosome recessive disorder. However, it has limitations in SMA diagnosis by Karyomapping, and these methods are unable to distinguish wildtype embryos with carriers effectively. Mutated allele revealed by sequencing with aneuploidy and linkage analyses(MARSALA) is a new method allowing embryo selection by a one-step next-generation sequencing(NGS) procedure, which has been applied in PGD for both autosome dominant and X-linked diseases in our group previously. In this study, we carried out PGD based on MARSALA for two carrier families with SMA affected children. As a result, one of the couples has given birth to a healthy baby free of mutations in SMA-causing gene. It is the first time that MARSALA was applied to PGD for SMA, and we can distinguish the embryos with heterozygous deletion(carriers) from the wild-type(normal) ones accurately through this NGS-based method. In addition, direct mutation detection allows us to identify the affected embryos(homozygous deletion), which can be regarded as probands for linkage analysis, in case that the affected family member is absent. In the future, the NGS-based MARSALA method is expected to be used in PGD for all monogenetic disorders with known pathogenic gene mutation. | Yixin Ren Xu Zhi Xiaohui Zhu Jin Huang Ying Lian Rong Li Hongyan Jin Yan Zhang Wenxin Zhang Yanli Nie Yuan Wei Zhaohui Liu Donghong Song Ping Liu Jie Qiao Liying Yan | 2016 | Journal of Genetics and Genomics2016，43，9： | 9 |

| 9 | The study of electroless Ni-W-P alloy plating on glass fibers显示文摘Ni-W-P coatings were deposited on the surface of glass fibers by the electroless plating process. The bath was very stable through the palladium salt test. There was no phenomenon of peeling and blistering on the surface of the Ni-W-P alloy glass fibers in the thermal shock test. It showed that the deposit had high impact strength and good adhesion. The morphology of the coatings was observed by scanning electron microscope (SEM). The elements and their contents were tested and analyzed by energy dispersion spectrometer (EDS). The tungsten content reached up to 12.1 wt.%. The effects of the concentrations of NiSO4, Na2WO4, and NaH2PO2·H2O on the conductivity of the coatings were studied. The resistivity of the Ni-W-P alloy glass fibers reached 7.39 × 10·3 ··cm. The alloy coatings on glass fibers were analyzed by XRD. The results indicated that the deposit had an amorphous structure and good heat stability. The suitable work temperature range was lower than 190°C. Finally, the electromagnetic parameters of the Ni-W-P alloy glass fibers were tested and analyzed primarily. The magnetic loss reached 0.04023 and the dielectric loss reached ·5.80239. The plated alloy is a kind of soft magnetic material. | HUANG Ying HUANG Fei ZHAO Wentao SHI Ke ZHAO Li WANG Yanli | 2007 | Rare Metals2007，26，4： | 8 |
| 10 | Huge thick conglomerate movement induced by full thick longwall mining huge thick coal seam显示文摘A discrete elemental method was used to study the thickness of conglomerate layer in a full thick seam mining activities under the influence of the law, pointing out the thickness of the conglomerate at different seam mining, and during the destruction and instability of existing state of laws. At 21141 thick seam mining, the face toward the direction of separation between the thick layer of conglomerate rock and the next bit after reaching its maximum capacity due to pull from the bottom of the plastic zone, formed a stratified and hierarchical down collapse. The shape of caving area is a ''triangular block'', the length of the plastic zone and face advancement from the linear fit between the height of the plastic zone and the advancing face is a quadratic function of distance, while the top layer of thick gravel layer is the overall bending subsidence trend. Tilting the direction of the face, a thick gob of collapsed conglomerate layer is formed in the coal gob entity on both sides of the thick conglomerate at the top of the overall fracture morphology performance, thus forming a mutual extrusion of articulated block structure. The instability, separation and balance of the thick conglomerate layer in the hinged block stope stress leads to abnormal occurrence of rock burst induced by face as the major factor in the accident. This research reveals the form of stress distribution in the destroyed layer of the thick conglomerate rock, analyzes the stope law of coupling for the pressure burst behavior law for the mining work face, and the choice of preventive measures to provide a theoretical basis and implementation. | Ma Liqiang Qiu xiaoxiang Dong Tao Zhang Jixiong Huang Yanli | 2012 | International Journal of Mining Science and Technology2012，22，3： | 7 |
| 11 | Experimental study on the mechanical properties and consolidation mechanism of microbial grouted backfill显示文摘Backfill mining technology is the practice of returning waste materials underground for both disposal and geotechnical stability,however,a challenge with current technologies is that they commonly require cement-based binders which have a relatively high environmental impact.Finding alternatives to cement-based binders can improve environmental performance and this paper proposes microbial grouted backfill(MGB)as a potential solution.In this paper,the effects of the cementation solution concentration(CSC),volume ratio of bacterial solution to cementation solution(VRBC),particle sizes of the aggregates,and the number of grouting batches on the mechanical properties of MGB are studied.The experimental results show that MGB strength increased,up to a peak value,as CSC was increased,before decreasing as CSC was increased further.The results also show that MGB strength increased,up to a peak value,as VRBC decreased,before decreasing as the VRBC was decreased further.The peak strength was achieved at a CSC of 2 mol/L and a VRBC of 1:9.The strength of the MGB also increased as the number of grouting batches increased.Graded MGB samples showed the highest UCS,25.12 MPa,at particle sizes of 0.2 to 0.8 mm,while full(non-graded)MGB samples displayed mean UCS values ranging from1.56 MPa when the maximum particle size was 0.2 mm,up to 13 MPa when the maximum particle size was 1.2 mm.MGB samples are consolidated by the calcium carbonate that is precipitated during microbial metabolism,and the strength of MGB increases linearly as calcium carbonate content increases.The calcium carbonate minerals produced in MGB materials are primarily calcite,with secondary amounts of vaterite. | Xuejie Deng Yu Li Fei Wang Xiaoming Shi Yinchao Yang Xichen Xu Yanli Huang Benjamin de Wit | 2022 | International Journal of Mining Science and Technology2022，32，2： | 7 |
| 12 | Fracture mechanics model of fully mechanized top coal caving of shallow coal seams and its application显示文摘Based on break characteristics of roofs in fully mechanized top-coal mining of thick shallow coal seams, a fracture mechanics model was built, and the criterion of crack propagation in the main roof was derived using the fracture mechanics theory. The relationships between the fracture length of the roof and the working resistance of the supports were discovered, and the correlations between the load on the overlying strata and the ratio of the crack's length to the thickness of the roof were obtained. Using a working face of Jindi Coal Mine, Xing county Shanxi province as an example, the relationships between the fracture length of the roof and the working resistance of the supports were analysed in detail. The results give a design basis in hydraulic top coal caving supports, which could provide useful references in the practical application. On-site experiment proves that the periodic weighting step interval of the caving face is 15–16 m, which is basically consistent with the theoretical analysis results, and indicates that the mechanized caving hydraulic support is capable of meeting the support requirements in the mining of a super-thick but shallowly buried coal seam. | Zhang Jiangong Miao Xiexing Huang Yanli Li Meng | 2014 | International Journal of Mining Science and Technology2014，24，3： | 6 |
| 13 | A Comparative Study on Hydrodynamic Performance of Double Deflector Rectangular Cambered Otter Board显示文摘In the present work,the hydrodynamic performance of the double deflector rectangular cambered otter board was studied using wind tunnel experiment,flume tank experiment and numerical simulation.Results showed that the otter board had a good hydrodynamic performance with the maximum lift-to-drag ratio(K_(MAX) = 3.70).The flow separation occurred when the angle of attack(AOA) was at 45?,which revealed that the double deflector structure of the otter board can delay the flow separation.Numerical simulation results showed a good agreement with experiment ones,and could predict the critical AOA,which showed that it can be used to study the hydrodynamic performance of the otter board with the advantage of flow visualization.However,the drag coefficient in flume tank was much higher than that in wind tunnel,which resulted in a lower lift-to-drag ratio.These may be due to different fluid media between flume tank and wind tunnel,which result in the big difference of the vortexes around the otter board.Given the otter boards are operated in water,it was suggested to apply both flume tank experiment and numerical simulation to study the hydrodynamic performance of otter board. | XU Qingchang FENG Chunlei HUANG Liuyi XU Jiqiang WANG Lei ZHANG Xun LIANG Zhenlin TANG Yanli ZHAO Fenfang WANG Xinxin | 2018 | Journal of Ocean University of China2018，17，5： | 5 |
| 14 | Significant Effects of Fishing Gear Selectivity on Fish Life History显示文摘Over the past few decades, extreme changes have occurred in the characters of exploited fish populations. The majority of these changes have affected the growth traits of fish life history, which include a smaller size-at-age, an earlier age-at-maturation and among others. Currently, the causes of these life history traits changes still require systematic analyses and empirical studies. The explanations that have been cited are merely expressed in terms of fish phenotypic adaptation. It has been claimed that the original traits of fish can be recovered once the intensity of exploitation of the fish is controlled. Sustained environmental and fishing pressure will change the life history traits of most fish species, so the fish individual's traits are still in small size-at-age and at earlier age-at-maturation in exploited fish populations. In this paper, we expressed our view of points that fishing gear has imposed selectivity on fish populations and individuals as various other environmental factors have done and such changes are unrecoverable. According to the existing tend of exploited fish individual's life history traits, we suggested further researches in this field and provided better methods of fishery management and thereby fishery resources protection than those available early. | LIANG Zhenlin SUN Peng YAN Wei HUANG Liuyi TANG Yanli | 2014 | Journal of Ocean University of China2014，13，3： | 4 |
| 15 | The Detecting System of Image Forgeries with Noise Features and EXIF Information显示文摘Recently, the digital image blind forensics technology has received an increasing attention in academic community. This paper aims at developing a new identification approach based on the statistical noise and exchangeable image file format(EXIF) information of image for images authentication. In particular, the authors can identify whether the current image has been modified or not by utilizing the relevance between noise and EXIF parameters and comparing the real values with the estimated values of the EXIF parameters. Experimental results validate the proposed method. That is, the detecting system can identify the doctored image effectively. | SUN Xiaoting LI Yezhou NIU Shaozhang HUANG Yanli | 2015 | Journal of Systems Engineering and Electronics2015，26，5： | 4 |
| 16 | Abnormal perturbations in the ionospheric F2 region before Wenchuan earthquake on 12 May 2008显示文摘On 12 May 2008 at 14:28 BJT, a great earthquake (M=8.0) occurred in Wenchuan (31.00°N, 103.40°E), China. The hourly foF2 from 5 to 12 May have been analyzed over four ionospheric observatories: Kunming (25.00°N, 102.70°E), Chongqing (29.50°N, 106.40°E), Lhasa (29.63°N, 91.17°E), and Lanzhou (36.07°N, 103.87°E). The results show that foF2 were notably abnormal from upper bound (the maximum abnormality up to 65% at 17:00 BJT) and lasted about 3 h on 9 May over Chongqing station. Moreover, there were obvious perturbations of foF2 on the same day over other stations except Lhasa. Taking into account that the solar activity and geomagnetic activity were very quiet during this period, we can conclude that the observed positive ionospheric perturbations were likely associated with the imminent earthquake. | Xu Tong Hu YanLi Wu Jian Wu ZhenSen Suo YuCheng Feng Jian Huang ChaoJun | 2010 | Science China Earth Sciences2010，53，11： | 4 |
| 17 | Telomere-to-telomere and gap-free reference genome assembly of the kiwifruit Actinidia chinensis显示文摘Kiwifruit is an economically and nutritionally important fruit crop with extremely high contents of vitamin C.However,the previously released versions of kiwifruit genomes all have a mass of unanchored or missing regions.Here,we report a highly continuous and completely gap-free reference genome of Actinidia chinensis cv.‘Hongyang’,named Hongyang v4.0,which is the first to achieve two de novo haploid-resolved haplotypes,HY4P and HY4A.HY4P and HY4A have a total length of 606.1 and 599.6 Mb,respectively,with almost the entire telomeres and centromeres assembled in each haplotype.In comparison with Hongyang v3.0,the integrity and contiguity of Hongyang v4.0 is markedly improved by filling all unclosed gaps and correcting some misoriented regions,resulting in∼38.6–39.5 Mb extra sequences,which might affect 4263 and 4244 protein-coding genes in HY4P and HY4A,respectively.Furthermore,our gap-free genome assembly provides the first clue for inspecting the structure and function of centromeres.Globally,centromeric regions are characterized by higher-order repeats that mainly consist of a 153-bp conserved centromere-specific monomer(Ach-CEN153)with different copy numbers among chromosomes.Functional enrichment analysis of the genes located within centromeric regions demonstrates that chromosome centromeres may not only play physical roles for linking a pair of sister chromatids,but also have genetic features for participation in the regulation of cell division.The availability of the telomere-to-telomere and gap-free Hongyang v4.0 reference genome lays a solid foundation not only for illustrating genome structure and functional genomics studies but also for facilitating kiwifruit breeding and improvement. | Junyang Yue Qinyao Chen Yingzhen Wang Lei Zhang Chen Ye Xu Wang Shuo Cao Yunzhi Lin Wei Huang He Xian Hongyan Qin Yanli Wang Sijia Zhang Ying Wu Songhu Wang Yi Yue Yongsheng Liu | 2023 | Horticulture Research2023，10，2： | 4 |

| 19 | Soil and Vegetation Spectral Coupling Difference (SVSCD) for Minerals Extraction from Hyperion Data in Vegetation Covered Area显示文摘Remote sensing data have been widely applied to extract minerals in geologic exploration, however, in areas covered by vegetation, extracted mineral information has mostly been small targets bearing little information. In this paper, we present a new method for mineral extraction aimed at solving the difficulty of mineral identification in vegetation covered areas. The method selected six sets of spectral difference coupling between soil and plant(SVSCD). These sets have the same vegetation spectra reflectance and a maximum different reflectance of soil and mineral spectra from Hyperion image based on spectral reflectance characteristics of measured spectra. The central wavelengths of the six, selected band pairs were 2314 and 701 nm, 1699 and 721 nm, 1336 and 742 nm, 2203 and 681 nm, 2183 and 671 nm, and 2072 and 548 nm. Each data set's reflectance was used to calculate the difference value. After band difference calculation, vegetation information was suppressed and mineral abnormal information was enhanced compared to the scatter plot of original band. Six spectral difference couplings, after vegetation inhibition, were arranged in a new data set that requires two components that have the largest eigenvalue difference from principal component analysis(PCA). The spatial geometric structure features of PC1 and PC2 was used to identify altered minerals by spectral feature fitting(SFF). The collecting rocks from the 10 points that were selected in the concentration of mineral extraction were analyzed under a high-resolution microscope to identify metal minerals and nonmetallic minerals. Results indicated that the extracted minerals were well matched with the verified samples, especially with the sample 2, 4, 5 and 8. It demonstrated that the method can effectively detect altered minerals in vegetation covered area in Hyperion image. | CHEN Shengbo HUANG Shuang LIU Yanli ZHOU Chao | 2018 | Chinese Geographical Science2018，28，6： | 3 |
| 20 | RATIONAL GENERAL SOLUTIONS OF HIGHER ORDER ALGEBRAIC ODES显示文摘This paper generalizes the method of Ngo and Winkler(2010,2011)for finding rational general solutions of a first order non-autonomous algebraic ordinary differential equation(AODE)to the case of a higher order AODE,provided a proper parametrization of its solution hypersurface.The authors reduce the problem of finding the rational general solution of a higher order AODE to finding the rational general solution of an associated system.The rational general solutions of the original AODE and its associated system are in computable 1-1 correspondence.The authors give necessary and sufficient conditions for the associated system to have a rational solution based on proper reparametrization of invariant algebraic space curves.The authors also relate invariant space curves to first integrals and characterize rationally solvable systems by rational first integrals. | HUANG Yanli NG L X Chu WINKLER Franz | 2013 | Journal of Systems Science & Complexity2013，26，2： | 3 |
