| 1 | Assessment of genetic diversity in broomcorn millet (Panicum miliaceum L.) using SSR markers显示文摘The genetic diversity of 118 accessions of broomcorn millet(Panicum miliaceum L.),collected from various ecological areas,was analyzed.Using 46 SSR(Simple Sequence Repeat) polymorphic markers from rice,wheat,oat and barley,a total of 226 alleles were found,which exhibited moderate level of diversity.The number of alleles per primer ranged from two to nine,with an average of 4.91.The range of polymorphism information content(PIC) was 0.284-0.980(average,0.793).The expected heterozygosity(He) varied from 0.346 to 0.989,with an average of 0.834.The average coefficient of the genetic similarity of SSR markers among the 118 accessions was 0.609,and it ranged from 0.461 to 0.851.The UPGMA(Unweight Pair Group Method with Arithmetic Mean) clustering analysis at the genetic similarity value of 0.609 grouped the 118 accessions into five groups.Mantel test meant that geographical origin and genetic distance presented positive correlation.The clustering results were consistent with known information on ecological growing areas.The genetic similarity coefficient of the accessions in the Loess Plateau ecotype was significantly lower than those in the other ecotypes.It indicates that the highest level of genetic diversity occurred in the Loess Plateau,which is probably the original site of Panicum miliaceum. | Xingyu Hu Jianfei Wang Ping Lu Hongsheng Zhang | 2009 | Journal of Genetics and Genomics2009，36，8： | 44 |
| 2 | Focal depth research of earthquakes in China's Mainland: Implication for tectonics显示文摘Focal depth data of earthquakes in China's Mainland are processed and analyzed in this paper, as well as the relationship between the focal depths and large-scale tectonic structures. As a basic parameter for earthquakes, focal depth is used to investigate deep environment of seis-mogenic regions, tectonic backgrounds for concentration and release of seismic energy, the inner crustal deformation and its mechanic features. Depth data of 31282 ML≥2.0 events with 1st class and 2nd class precision in China's Mainland from Jan. 1, 1970 to May 31, 2000 are used to get spatial features of earthquakes distributed with depth and to provide average depth for each grid area throughout China. Researches show that the average depth (D) for all the earthquakes used in this paper is (16±7) km, and (13±6) km and (18±8) km for the events in eastern China and western China, respectively. The area with the deepest focal depth is located in southwest Xinjiang region, near the western and southwestern ends of the Tarim | ZHANG Guomin WANG Suyun LI Li ZHANG Xiaodong MA Hongsheng | 2002 | Chinese Science Bulletin2002，47，12： | 38 |

| 4 | Aerosol and boundary-layer interactions and impact on air quality显示文摘Air quality is concerned with pollutants in both the gas phase and solid or liquid phases. The latter are referred to as aerosols, which are multifaceted agents affecting air quality, weather and climate through many mechanisms. Unlike gas pollutants, aerosols interact strongly with meteorological variables with the strongest interactions taking place in the planetary boundary layer(PBL). The PBL hosting the bulk of aerosols in the lower atmosphere is affected by aerosol radiative effects. Both aerosol scattering and absorption reduce the amount of solar radiation reaching the ground and thus reduce the sensible heat fluxes that drive the diurnal evolution of the PBL. Moreover, aerosols can increase atmospheric stability by inducing a temperature inversion as a result of both scattering and absorption of solar radiation, which suppresses dispersion of pollutants and leads to further increases in aerosol concentration in the lower PBL.Such positive feedback is especially strong during severe pollution events. Knowledge of the PBL is thus crucial for understanding the interactions between air pollution and meteorology. A key question is how the diurnal evolution of the PBL interacts with aerosols, especially in vertical directions, and affects air quality.We review the major advances in aerosol measurements, PBL processes and their interactions with each other through complex feedback mechanisms, and highlight the priorities for future studies. | Zhanqing Li Jianping Guo Aijun Ding Hong Liao Jianjun Liu Yele Sun Tijian Wang Huiwen Xue Hongsheng Zhang Bin Zhu | 2017 | National Science Review2017，4，6： | 37 |

| 6 | Policy Analysis and Development Evaluation of Digital Trade:An International Comparison显示文摘As an extension of traditional trade,digital trade is a new type of trade in the era of the digital economy.In this paper,we first analyze the digital trade-related strategies of eight leading economies through word clouds and dissect China s digital trade-related policies using the word frequency method by sorting through the digital trade-related policy documents of 26 economies and Chinese provinces.We then evaluate the status quo of digital trade development in 111 countries and Chinese provinces by building a digital trade index system to determine the development environment and market potential.The results show that all countries attach great importance to digital technology,data and government guidance in the development of digital trade.The results also reveal that'development,''service'and'construction'are the three most frequently used words in various Chinese documents.The overall level of China s digital trade is at the global vanguard,but is characterized by uneven regional development.In the era of digital trade,traditional international trade theory is also in urgent need of breakthroughs and innovation. | Shuzhong Ma Jiwen Guo Hongsheng Zhang | 2019 | China & World Economy2019，27，3： | 29 |
| 7 | Comparison of the Δ^(12) fatty acid desaturase gene between high-oleic and normal-oleic peanut genotypes显示文摘Δ12 fatty acid desaturase gene has been targeted as a logical candidate controlling the high oleate trait in peanut seeds.By RT-PCR method,the full-length cDNAs of Δ12 fatty acid desaturase gene were isolated from peanut(Arachis hypogaea L.) genotypes with normal and high ratio of oleic to linoleic acid,which were designated AhFAD2B and AhFAD2B',respectively.Sequence alignment of their coding regions revealed that an extra A was inserted at the position +442 bp of AhFAD2B' sequence of high oleic acid genotypes,which resulted in the shift of open reading frame and a truncated protein AhFAD2B',with the loss of one histidine box involved in metal ion complex required for the reduction of oxygen.Analysis of transcript level showed that the expression of Δ12 fatty acid desaturase gene in high oleic acid genotype was slightly lower than that in normal genotype.The enzyme activity experiment of yeast(Saccharomyces cerevisiae) cell transformed with AhFAD2B or AhFAD2B' proved that only AhFAD2B gene product showed significant Δ12 fatty acid desaturase activity,but AhFAD2B' gene product did not.These results suggested that the change of AhFAD2B' gene sequence resulted in lower activity or deactivation of Δ12 fatty acid desaturase in high oleic acid genotype. | ShanlinYu Lijuan Pan Qingli Yang Ping Min Zengkai Ren Hongsheng Zhang | 2008 | Journal of Genetics and Genomics2008，35，11： | 23 |
| 8 | Characteristics of Boundary Layer Structure during a Persistent Haze Event in the Central Liaoning City Cluster, Northeast China显示文摘The characteristics of boundary layer structure during a persistent regional haze event over the central Liaoning city cluster of Northeast China from 16 to 21 December 2016 were investigated based on the measurements of particulate matter(PM) concentration and the meteorological data within the atmospheric boundary layer(ABL). During the observational period, the maximum hourly mean PM_(2.5) and PM10 concentrations in Shenyang, Anshan, Fushun, and Benxi ranged from 276 to 355 μg m–3 and from 378 to 442 μg m–3, respectively, and the lowest hourly mean atmospheric visibility(VIS) in different cities ranged from 0.14 to 0.64 km. The central Liaoning city cluster was located in the front of a slowly moving high pressure and was mainly controlled by southerly winds. Wind speed(WS) within the ABL(< 2 km) decreased significantly and WS at 10-m height mostly remained below 2 m s–1 during the hazy episodes, which was favorable for the accumulation of air pollutants. A potential temperature inversion layer existed throughout the entire ABL during the earlier hazy episode [from 0500 Local Time(LT) 18 December to 1100 LT 19 December], and then a potential temperature inversion layer developed with the bottom gradually decreased from 900 m to 300 m. Such a stable atmospheric stratification further weakened pollutant dispersion. The atmospheric boundary layer height(ABLH) estimated based on potential temperature profiles was mostly lower than 400 m and varied oppositely with PM_(2.5) in Shenyang. In summary, weak winds due to calm synoptic conditions, strong thermal inversion layer, and shallow atmospheric boundary layer contributed to the formation and development of this haze event.The backward trajectory analysis revealed the sources of air masses and explained the different characteristics of the haze episodes in the four cities. | Xiaolan LI Yangfeng WANG Lidu SHEN Hongsheng ZHANG Hujia ZHAO Yunhai ZHANG Yanjun MA | 2018 | Journal of Meteorological Research2018，32，2： | 10 |

| 12 | Characteristics of Turbulent Transfer during Episodes of Heavy Haze Pollution in Beijing in Winter 2016/17显示文摘We analyzed the structure and evolution of turbulent transfer and the wind profile in the atmospheric boundary layer in relation to aerosol concentrations during an episode of heavy haze pollution from 6 December 2016 to 9 January 2017. The turbulence data were recorded at Peking University's atmospheric science and environment observation station. The results showed a negative correlation between the wind speed and the PM2.5 concentration. The turbulence kinetic energy was large and showed obvious diurnal variations during unpolluted(clean) weather, but was small during episodes of heavy haze pollution. Under both clean and heavy haze conditions, the relation between the non-dimensional wind components and the stability parameter z/L followed a 1/3 power law, but the normalized standard deviations of the wind speed were smaller during heavy pollution events than during clean periods under near-neutral conditions. Under unstable conditions, the normalized standard deviation of the potential temperatureσ_θ/|θ_*| was related to z/L, roughly following a –1/3 power law, and the ratio during pollution days was greater than that during clean days. The three-dimensional turbulence energy spectra satisfied a –2/3 power exponent rate in the high-frequency band. In the low-frequency band, the wind velocity spectrum curve was related to the stability parameters under clear conditions, but was not related to atmospheric stratification under polluted conditions. In the dissipation stage of the heavy pollution episode, the horizontal wind speed first started to increase at high altitudes and then gradually decreased at lower altitudes. The strong upward motion during this stage was an important dynamic factor in the dissipation of the heavy haze. | Yan REN Shuwen ZHENG Wei WEI Bingui WU Hongsheng ZHANG Xuhui CAI Yu SONG | 2018 | Journal of Meteorological Research2018，32，1： | 9 |

| 14 | Lateral Flight Technical Error Estimation Model for Performance Based Navigation显示文摘Flight technical error (FTE) combined with navigation system error (NSE) is the main part of total system error (TSE) in performance based navigation (PBN).The implementation of PBN requires pre-flight prediction and en-route short-term dynamical prediction of the TSE.Once the sum of predicted lateral FTE and NSE is greater than the specified PBN value,the PBN cannot operate.Thus,accurate modeling and thorough analysis of lateral FTE are indispensible.Multiple-input multiple-output (MIMO) lateral track control system of a transport aircraft is designed using linear quadratic Gaussian and loop transfer recovery (LQG/LTR) method,and the lateral FTE of a turbulence disturbed approach operation is analyzed.The error estimation mapping function of latera FTE and its bound estimation algorithm are proposed based on singular value theory.According to the forming mechanism of lateral FTE,the algorithm considers environmental turbulence fluctuation disturbance,aircraft dynamics and control system parameters.Real-data-based Monte-Carlo simulation validates the theoretical analysis of FTE.It also shows that FTE is mainly caused by turbulence fluctuation disturbance when automatic flight control system (AFCS) is engaged and would increase with escalating environmental turbulence intensity. | ZHAO Hongsheng XU Xiaohao ZHANG Jun ZHU Yanbo YANG Chuansen HONG Sheng | 2011 | Chinese Journal of Aeronautics2011，24，3： | 8 |
| 15 | Performing optical logic operations by a diffractive neural network显示文摘Optical logic operations lie at the heart of optical computing,and they enable many applications such as ultrahighspeed information processing.However,the reported optical logic gates rely heavily on the precise control of input light signals,including their phase difference,polarization,and intensity and the size of the incident beams.Due to the complexity and difficulty in these precise controls,the two output optical logic states may suffer from an inherent instability and a low contrast ratio of intensity.Moreover,the miniaturization of optical logic gates becomes difficult if the extra bulky apparatus for these controls is considered.As such,it is desirable to get rid of these complicated controls and to achieve full logic functionality in a compact photonic system.Such a goal remains challenging.Here,we introduce a simple yet universal design strategy,capable of using plane waves as the incident signal,to perform optical logic operations via a diffractive neural network.Physically,the incident plane wave is first spatially encoded by a specific logic operation at the input layer and further decoded through the hidden layers,namely,a compound Huygens’metasurface.That is,the judiciously designed metasurface scatters the encoded light into one of two small designated areas at the output layer,which provides the information of output logic states.Importantly,after training of the diffractive neural network,all seven basic types of optical logic operations can be realized by the same metasurface.As a conceptual illustration,three logic operations(NOT,OR,and AND)are experimentally demonstrated at microwave frequencies. | Chao Qian Xiao Lin Xiaobin Lin Jian Xu Yang Sun Erping Li Baile Zhang Hongsheng Chen | 2020 | Light(Science & Applications)2020，9，1： | 8 |
| 16 | The plate contact geometry investigation based on earthquake source parameters at the Burma arc subduction zone显示文摘Accurately characterizing the three-dimensional geometric contacts between the crust of the Chinese mainland and adjacent regions is important for understanding the dynamics of this part of Asia from the viewpoint of global plate systems.In this paper,a method is introduced to investigate the geometric contacts between the Eurasian and Indian plates at the Burma arc subduction zone using earthquake source parameters based on the Slab1.0 model of Hayes et al.(2009,2010).The distribution of earthquake focus depths positioned in 166 sections along the Burma Arc subduction zone boundary has been investigated. Linear plane fitting and curved surface fitting has been performed on each section.Three-dimensional geometric contacts and the extent of subduction are defined quantitatively.Finally,the focal depth distribution is outlined for six typical sections along the Burma arc subduction zone,combining focal mechanisms with background knowledge of geologic structure.Possible dynamic interaction patterns are presented and discussed.This paper provides an elementary method for studying the geometric contact of the Chinese mainland crust with adjacent plates and serves as a global reference for dynamic interactions between plates and related geodynamic investigations. | ZHANG LangPing SHAO ZhiGang MA HongSheng WANG XingZhou LI ZhiHai | 2013 | Science China Earth Sciences2013，56，5： | 8 |
| 17 | Influence of filler-bitumen ratio on performance of modified asphalt mortar by additive显示文摘When the filler-bitumen ratio of asphalt mortar changes, its adhesion and viscoelasticity will also change, as well as its performance at the high and low temperatures, fatigue durability, and ductility. Thus, the appropriate filler- bitumen ratio directly affects the asphalt mortar's performance. This paper tested the physical indexes of the No. 70 matrix asphalt mortar modified by additive Sasobit (SB) and Sasowam (SW) through dynamic shear rheometer and bending beam rheometer under different temperature conditions, and comprehensively analyzed the high-temperature anti-rutting and fatigue performance, low-temperature crack resistance performance, and ductility of asphalt mortar. The results show that ore powder not only can increase the antirutting factor but also can increase the aging resistance of asphalt. SB has better performances than SW at high temperatures. As for the filler-bitumen ratio of asphalt mortar with additive SB, the recommended value is between 0.8 and 1.2, and the value may be a little larger for that with SW. | Hongsheng Qiu Ximing Tan Shu Shi Heng Zhang | 2013 | Journal of Modern Transportation2013，21，1： | 7 |
| 18 | A fundamental theorem for eco-environmental surface modelling and its applications显示文摘We propose a fundamental theorem for eco-environmental surface modelling(FTEEM) in order to apply it into the fields of ecology and environmental science more easily after the fundamental theorem for Earth’s surface system modeling(FTESM). The Beijing-Tianjin-Hebei(BTH) region is taken as a case area to conduct empirical studies of algorithms for spatial upscaling, spatial downscaling, spatial interpolation, data fusion and model-data assimilation, which are based on high accuracy surface modelling(HASM), corresponding with corollaries of FTEEM. The case studies demonstrate how eco-environmental surface modelling is substantially improved when both extrinsic and intrinsic information are used along with an appropriate method of HASM. Compared with classic algorithms, the HASM-based algorithm for spatial upscaling reduced the root-meansquare error of the BTH elevation surface by 9 m. The HASM-based algorithm for spatial downscaling reduced the relative error of future scenarios of annual mean temperature by 16%. The HASM-based algorithm for spatial interpolation reduced the relative error of change trend of annual mean precipitation by 0.2%. The HASM-based algorithm for data fusion reduced the relative error of change trend of annual mean temperature by 70%. The HASM-based algorithm for model-data assimilation reduced the relative error of carbon stocks by 40%. We propose five theoretical challenges and three application problems of HASM that need to be addressed to improve FTEEM. | Tianxiang YUE Na ZHAO Yu LIU Yifu WANG Bin ZHANG Zhengping DU Zemeng FAN Wenjiao SHI Chuanfa CHEN Mingwei ZHAO Dunjiang SONG Shihai WANG Yinjun SONG Changqing YAN Qiquan LI Xiaofang SUN Lili ZHANG Yongzhong TIAN Wei WANG Ying’an WANG Shengnan MA Hongsheng HUANG Yimin LU Qing WANG Chenliang WANG Yuzhu WANG Ming LU Wei ZHOU Yi LIU Xiaozhe YIN Zong WANG Zhengyi BAO Miaomiao ZHAO Yapeng ZHAO Yimeng JIAO Ufra NASEER Bin FAN Saibo LI Yang YANG John PWILSON | 2020 | Science China Earth Sciences2020，63，8： | 7 |
| 19 | Assessment of genetic variation in tomato (Solanum lycopersicum L.) inbred lines using SSR molecular markers显示文摘A study was conducted to determine the genetic diversity of 39 determinate and indeterminate tomato inbred lines collected from China,Japan,S. Korea,and USA. Using 35 SSR polymorphic markers,a total of 150 alleles were found with moderate levels of diversity,and a high number of unique alleles existing in these tomato lines. The mean number of alleles per locus was 4.3 and the average poly-morphism information content (PIC) was 0.31. Unweighted Pair Group Method with Arithmetic Mean (UPGMA) clustering at genetic similarity value of 0.85 grouped the inbred lines into four groups,where one USA cultivar formed a separate and more distant cluster. The most similar inbred lines are from USA,both with determinate type,whereas the most different lines are from USA (Us-16) and Japan (Ja-2) with determinate and indeterminate growth habit,respectively. Clustering was consistent with the known information regarding geographical location and growth habit. The genetic distance information reported in this study might be used by breeders when planning future crosses among these inbred lines. | Solomon Benor Mengyu Zhang Zhoufei Wang Hongsheng Zhang | 2008 | Journal of Genetics and Genomics2008，35，6： | 7 |
| 20 | Coupling effects of tungsten and molybdenum on microstructure and stress-rupture properties of a nickel-base cast superalloy显示文摘In order to comprehensively understand the forming mechanism of abnormal phases solidified in a nickel-base cast superalloy with additives of tungsten and molybdenum, the coupling effects of W and Mo on the microstructure and stress-rupture properties were investigated in this paper. The results indicated that the precipitation of primary α-(W, Mo) phase depended tremendously on the amount of W and Mo addition. When the total amount of W and Mo was greater than 5.79 at%, α-(W, Mo) phase became easily precipitated in the alloy.With increasing of Mo/W ratio, the dendrite-like α-(W, Mo) phases were apt to convert into small bars or blockylike phases at the vicinities of γ′/γ eutectic. The morphological changes of α-(W, Mo) phase can be interpreted as the non-equilibrium solidification of W and Mo in the alloy. Since the large sized α-(W, Mo) phase has detrimental effects on stress-rupture properties in as-cast conditions, secondary cracks may mainly initiate at and then propagate along the interfaces of brittle phases and soft matrix. During exposing at 1100 ℃ for 1000 h, the α-(W, Mo) phases transformed gradually into bigger and harder M_6C carbide, which results in decreasing of stress-rupture properties of the alloy. Finally, the alloy with an addition of 14W-1Mo(wt%) maintained the longest stress lives at high temperatures and therefore it revealed the best microstructure stability after 1100 ℃/1000 h thermal exposure. | Tongjin Zhou Wei Feng Huibin Zhao Yu Meng Huaxia Zhang Hongsheng Ding Zichen Wang | 2018 | Progress in Natural Science:Materials International2018，28，1： | 7 |
