| 1 | Identification and mapping of genes for improving yield from Chinese common wild rice (O.rufipogon Griff.) using advanced backcross QTL analysis显示文摘To identify useful genes from wild rice which have been lost or weakened in cultivated rice has become more and more important for modern breeding strategy. In this study, a BC4 population derived from 94W1, an accession of common wild rice (Oryza rufipogon Griff.) from Dongxiang in Jiangxi Province of China, as the donor, and a high-yielding Indica cultivar (O. sativa L.), 'Guichao 2', as the recipient, was used to identify quantitative trait loci (QTL) associated with yield and its components. Based on the analysis for the genotype of BC4F1 population with 87 SSR markers distributed throughout the genome and investigation of the plant height, yield and yield components of BC4F2, a total of 52 QTLs, were detected. Of 7 QTLs associated with grain yield per plant, 2 QTLs on chromosome 2 and chromosome 11 for grain yield, explaining 16% and 11% of the phenotypic variance respectively, were identified. The alleles from Dongxiang common wild rice in those two loci could increase the yield of 'Guichao 2' by | Dejun Li Chuanqing Sun Yongcai Fu Cheng Li Zuofeng Zhu Liang Chen Hongwei Cai Xiangkun Wang | 2002 | Chinese Science Bulletin2002，47，18： | 39 |
| 2 | Identification and mapping of quantitative trait loci controlling cold-tolerance of Chinese common wild rice (O. rufipogon Griff.) at booting to flowering stages显示文摘An advanced backcross population of rice was used to identify the quantitative trait locus (QTL) controlling the cold-tolerance at booting to flowering stages. The recipient, Guichao 2 (GC2), was a commercial Indica rice; the donor Dongxiang common wild rice, was an accession of common wild rice (DXCWR, Oryza rufipogon Griff.). Three QTLs for cold-tolerance were detected on chromosomes 1, 6 and 11. Two of them coming from DXCWR could enhance the cold-tolerance of the backcross progenies. Moreover, one sterility QTL that could reduce the seed set rate of the backcross progenies by 78% was mapped on chromosome 5. | LIU Fengxia, SUN Chuanqing, TAN Lubin, FU Yongcai, LI Dejun & WANG Xiangkun Department of Plant Genetics and Breeding, China Agricultural University, National Key Laboratory of Agrobiology, Key Laboratory of Crop Genetic Improvement and Genome of the Ministry of Agriculture, Beijing 100094, China | 2003 | Chinese Science Bulletin2003，48，19： | 29 |
| 3 | Drift characteristics of green macroalgae in the Yellow Sea in 2008 and 2010显示文摘In order to investigate the aggregation mechanism of green macroalgae (Enteromorpha prolifera) on the Qingdao coastline,the macroalgal drift characteristics in the Yellow Sea during June and July in 2008 and 2010 were simulated using a three-dimensional wave-tide-circulation coupled model.In June 2008,the monthly-mean surface current flowed onshore and its direction was almost perpendicular to the Qingdao coastline,which was identified as the main reason for a huge accumulation of algae in the coastal waters off Qingdao.The current became parallel to the coastline in July 2008;this shift in current direction led to little accumulation of algae near Qingdao and thus relieved the environmental pressure on the Olympic sailing events.By using the coupled model,we predicted that there would be no serious algal accumulation at Qingdao in late June 2010,which was later confirmed by observations.This study demonstrated that the drift path of macroalgae near Qingdao is mainly controlled by the surface current,which is primarily driven by wind.Regional climate change is therefore one of the means by which physical processes affect marine ecosystems. | QIAO FangLi WANG GuanSuo LüXinGang DAI DeJun | 2011 | Chinese Science Bulletin2011，56，21： | 25 |

| 5 | Predicting the spread of nuclear radiation from the damaged Fukushima Nuclear Power Plant显示文摘Japan suffered a M9.0 earthquake and massive tsunami on March 11, 2011, which seriously damaged the Fukushima Nuclear Power Plant and caused a nuclear crisis. The spread of nuclear radiation from the power plant through the atmosphere and ocean was predicted with a short-term climate forecasting model and an ocean circulation model under some idealized assumptions. If nuclear matter were leaked in the near-ground layer of 992 hPa, the climate model results show that the nuclear radiation would cover North America 10 days after the initial leakage, with the concentration at the forefront dramatically reduced to 10 millionths of the initial model concentration at the source. The radiation would span Europe in 15 days and cover much of the Northern Hemisphere in 30 days. If the initial leakage was assumed to occur in the layer 5000-m above the ground, the radiation would cover Europe in 10 days and cover much of the Northern Hemisphere in 15 days. Moreover, under the assumption that the nuclear matter leaked in the 10000-m layer, the radiation would affect much of China after 10 days. The ocean circulation model indicates that the nuclear material would be slowly transported northeast of Fukushima and reach 150°E in 50 days, and the nuclear debris in the ocean would be confined to a narrow band. Compared with the spread in the ocean, the area affected by leaked nuclear radiation in the atmosphere would be very large. Atmospheric monitors in North America and Europe will be helpful for estimating the effect in China of any leaked nuclear material. | QIAO FangLi WANG GuanSuo ZHAO Wei ZHAO JieChen DAI DeJun SONG YaJuan SONG ZhenYa | 2011 | Chinese Science Bulletin2011，56，18： | 18 |

| 7 | Passive source range estimation with a single receiver in shallow water显示文摘An approach for long-range passive impulsive source ranging with a single receiver in shallow water is proposed,which utilizes the frequency spectrum of the warped signal autocorrelation function via warping transform.For an ideal waveguide,there are invariable frequency features both in the frequency spectrum of the warped signal corresponding to modal cut-off frequencies and the warped signal autocorrelation function due to modal interference.These intrinsic frequency features can be used to passive source ranging.So,the approximate relationship between the frequency of warped signal at an unknown source range and the intrinsic frequency extracted by the time warping transform is derived.These rules can be generalized to an actual shallow water waveguide.Employing an acoustic model to offer the invariable frequency spectrum features,the impulsive signal data collected by a single hydrophone in the North Yellow Sea in December 2011 are analyzed to verify the proposed source ranging approach.The estimated ranges are in good agreement with the ranges measured by GPS,and the mean relative error of range estimation is less than 10%. | QI Yubo ZHOU Shihong REN Yun WANG Dejun LIU Jianjun FENG Xiqiang | 2015 | Chinese Journal of Acoustics2015，34，1： | 13 |

| 9 | One-Step, Solvothermal Synthesis of Graphene-CdS and Graphene-ZnS Quantum Dot Nanocomposites and Their Interesting Photovoltaic Properties显示文摘The synthesis of graphene-semiconductor nanocomposites has attracted increasing attention due to their interesting optoelectronic properties.However the synthesis of such nanocomposites,with decorated particles well dispersed on graphene,is still a great challenge.This work reports a facile,one-step,solvothermal method for the synthesis of graphene-CdS and graphene-ZnS quantum dot nanocomposites directly from graphene oxide,with CdS and ZnS very well dispersed on the graphene nanosheets.Photoluminescence measurements showed that the integration of CdS and ZnS with graphene significantly decreases their photoluminescence.Transient photovoltage studies revealed that the graphene-CdS nanocomposite exhibits a very unexpected strong positive photovoltaic response,while separate samples of graphene and CdS quantum dots(QDs)of a similar size do not show any photovoltaic response. | Ping Wang Tengfei Jiang Chengzhou Zhu Yueming Zhai Dejun Wang Shaojun Dong | 2010 | Nano Research2010，3，11： | 8 |

| 12 | Haplotype variations in QTL for salt tolerance in Chinese wheat accessions identified by marker-based and pedigree-based kinship analyses显示文摘Most modern wheat cultivars were selected on the basis of yield-related indices measured under optimal fertilizer and irrigation inputs.With climate change,land degradation and salinity caused by sea water encroachment,wheat is increasingly subjected to environmental stress.Moreover,expanding urbanization increasingly encroaches upon prime agricultural land in countries like China,and alternative cropping areas must be found.Some of these areas have moderate constraining factors,such as salinity.Therefore,it is important to investigate whether current genetic materials and breeding procedures are maintaining adequate variability to address future problems caused by abiotic stress.In this study,a panel of 307 wheat accessions,including local landraces,exotic cultivars used in Chinese breeding programs and Chinese cultivars released during different periods since1940,were subjected to a genome-wide association study to dissect the genetic basis of salinity tolerance.Both marker-based and pedigree-based kinship analyses revealed that favorable haplotypes were introduced in some exotic cultivars as well as a limited number of Chinese landraces from the 1940 s.However,improvements in salinity tolerance during modern breeding are not as obvious as that of yield.To broaden genetic diversity for increasing salt tolerance,there is a need to refocus attention on local landraces that have high degrees of salinity tolerance and carry rare favorable alleles that have not been exploited in breeding. | Shizhou Yu Jianhui Wu Meng Wang Weiming Shi Guangmin Xia Jizeng Jia Zhensheng Kang Dejun Han | 2020 | The Crop Journal2020，8，6： | 4 |

| 14 | The effects of modulation period,modulation ratio,and deposition temperature on microstructure and mechanical properties of ZrB_2/W multilayers显示文摘Monolithic ZrB2,W coatings and ZrB2/W multilayers with different modulation periods and modulation ratios were synthesized by ion beam assisted deposition at room temperature and 400°C.X-ray diffraction (XRD),scanning electron microscopy (SEM),surface profiler,and nanoindention were employed to investigate the influences of the deposition temperature and the modulation period on the growth,textures,interface structure,and mechanical properties of the multilayers.The results indicated that the multilayer with modulation period of 13 nm synthesized at room temperature possessed a higher hardness of 23.8 GPa.Deposition temperature gave a significant contribution to mechanical property enhancement.The 400°C-deposition temperature led to a maximum hardness and elastic modulus value of 32.1 and 399.1 GPa for ZrB2/W multilayer with a modulation period of 6.7 nm.Its critical load increased to 42.8 mN and residual stress decreased to -0.7 GPa.A higher deposition temperature can cause an increase in interfacial atomic mixture and mobility of surface species,which induceds an increase in areal atomic density and dislocation pinning.These results as well as small nanoscale grain sizes should be related to hardness increase. | LIU MengYin,TAN Ming,LIU GuangQing,WANG HaiYuan,XUE FengYing,DENG XiangYun & LI DeJun College of Physics and Electronic Information Science,Tianjin Normal University,Tianjin 300387,China | 2010 | Science China(Technological Sciences)2010，53，9： | 4 |
| 15 | A 2D-numerical modeling of the generation and propagation of internal solitary waves in the Luzon Strait显示文摘The wide presence of internal solitary waves (ISWs) in the northern South China Sea (SCS) has been confirmed by both Synthetic Aperture Radar (SAR) images and in situ observations.These ISWs are believed being generated over the varying topography in the Luzon Strait.They typically propagate westwards into the SCS with a diurnal or semidiurnal period.Their generation sites are,however,not yet solidly identified.To obtain a clear picture of the ISWs,we designed numerical experiments to analyze the generation and propagation of the ISWs in the Luzon Strait using a 2-dimensional non-hydrostatic model.The model current is forced by barotropic or baroclinic currents imposed at open boundaries.The experiments show that the tidal current serves as a kind of triggering force for the ISWs over the submarine ridges in the strait.Under the forcing of tidal currents,depressions are formed near the ridges.The ISWs then split from the depressions through a process different from lee-wave generation mechanism.The appearance of the ISWs is influenced by the strength and period of the forcing current: the ISWs are more likely to be generated by a stronger tidal current.That is why the ISWs in the Luzon Strait are frequently observed during spring tide.Compared with diurnal tidal current,the ISWs generated by semidiurnal tidal current with the same amplitude is much more energetic.It is partly because that the wave beams in diurnal frequency have a larger angle with the vertical direction,thus are more likely to be reflected by the topography slope.The impact of the Kuroshio to the ISWs is also analyzed by adding a vertical uniform or shear current at boundaries.A vertically uniform current may generate ISWs directly.On the other hand,a vertically shear current,which is more realistic to represent the Kuroshio branch,seems to have little influence on the generation process and radiating direction of the ISWs in the Luzon Strait. | WANG Gang QIAO Fangli DAI Dejun | 2010 | Acta Oceanologica Sinica2010，29，6： | 4 |
| 16 | A UNIFIED MULTIAXIAL FATIGUE DAMAGE PARAMETER显示文摘According to the critical plane principle,a unified multiaxial fatigue damage parameteris presented based on the varying behaviour of the strains on the critical plane.Both the parameters ofthe maximum shear strain amplitude and normal strain excursion between adjacent turning points ofthe maximum shear strain on the critical plane are considered in the multiaxiaI fatigue damage parame-ter presented.An equivalent strain amplitude is made with both parameters of the maximun shearstrain amplitude and normal strain excursion by means of yon Mises criterion.Thus a new multiaxialfatigue damage model is given based on the critical plane approach.The results show that the multiaxi-al fatigue damage parameter proposed in this paper may be used under either proportional or nonpro-portional loading,and may also be reduced to a uniaxial form.It is used to predict multiaxial fatiguelife and good agreement is demonstrated by experimental data. | Shang Deguang Wang Dejun Xu Hao | 1998 | Acta Mechanica Solida Sinica1998，11，3： | 4 |
| 17 | Nondestructive detection of infertile hatching eggs based on spectral and imaging information显示文摘In order to quickly distinguish infertile eggs from fertile eggs,the hyperspectral imaging technology consisting of imaging and spectral information was used for detecting the fertile information of eggs.Before hatching eggs were incubated,a hyperspectral imaging system(wavelength between 400 to 1000 nm)was used to acquire the images one-by-one manually.The characteristic information of ratios of length to short axis,elongation,roundness and the ratios of the yolk area to the whole area was extracted based on the images.The normalization method was used as the spectral data preprocessing,and then 155 spectral characteristic variables were extracted from 520 nm waveband through the correlation coefficient method.Principal component analysis(PCA)method was adopted to reduce the dimensions of image-spectrum fusion information;the top six principal components were extracted.Support vector machine(SVM)method was used to establish classification of fertile and infertile eggs models,which are based on image,spectrum and image-spectrum fusion information respectively.The accuracy rates of the SVM models were 84.00%,90.00%and 93.00%respectively.The experimental results show that the model based on image-spectrum fusion information technology is superior to the single information model.Hyperspectral transmission imaging technology is effective and feasible to detect the fertile hatching eggs before incubation. | Zhu Zhihui Liu Ting Xie Dejun Wang Qiaohua Ma Meihu | 2015 | International Journal of Agricultural and Biological Engineering2015，8，4： | 4 |

| 19 | Experimental and numerical study of coal-rock bimaterial composite bodies under triaxial compression显示文摘To accurately predict coal burst hazards and estimate the failure of coal pillars in underground coal mining systems,it is of great significance to understand the mechanical behavior of coal-rock bimaterial composite structures.This paper presents experimental and numerical investigations on the response of rock-coal,coal-rock,and rock-coal-rock bimaterial composite structures under triaxial compression.The triaxial compression experiments are conducted under confining pressures in the range of 0-20 MPa.The resulting inside fracture networks are detected using X-ray-based computed tomography(CT).The experimentally observed data indicate that the mechanical parameters of the rock-coalrock composites are superior to those of the rock-coal and coal-rock combinations.After compression failure,the coal-rock combination specimens are analyzed via X-ray CT.The results display that the failure of the coal-rock composite bodies primarily takes place within the coal.Further,the bursting proneness is reduced by increasing confining pressure.Subsequently,the corresponding numerical simulations of the experiments are carried out by using the particle flow code.The numerical results reveal that coal is vulnerable with regard to energy storage and accumulation. | Yulong Chen Jianping Zuo Dejun Liu Yingjie Li Zhenbo Wang | 2021 | International Journal of Coal Science & Technology2021，8，5： | 3 |
| 20 | Sound propagation from the shelfbreak to deep water显示文摘Motivated by a phenomenon in an experiment conducted in the Northwestern Pacific indicating that the energy of the received signal around the sound channel axis is much greater than that at shallower depths,we study sound propagation from the transitional area(shelfbreak)to deep water.Numerical simulations with different source depths are first performed,from which we reach the following conclusions.When the source is located near the sea surface,sound will be strongly attenuated by bottom losses in a range-independent oceanic environment,whereas it can propagate to a very long range because of the continental slope.When the source is mounted on the bottom in shallow water,acoustic energy will be trapped near the sound channel axis,and it converges more evidently than the case where the source is located near the sea surface.Then,numerical simulations with different source ranges are performed.By comparing the relative energy level in the vertical direction between the numerical simulations and the experimental data,the range of the air-gun source can be approximated. | QIN JiXing ZHANG RenHe LUO WenYu PENG ZhaoHui LIU JianJun WANG DeJun | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，6： | 3 |
