| 1 | Research progress of heavy metal pollution in China:Sources,analytical methods,status,and toxicity显示文摘Heavy metal pollution is one of the most serious environmental problems in China and a large number of people are threatened by heavy metal pollution.Extensive damage to human organs,such as liver,kidney,digestion system,and nervous system can be caused by uptake of excess heavy metals.Heavy metals in the environment can originate from both natural and anthropogenic sources.Although contamination of heavy metals has been known to be a severe environmental problem for decades,it is still getting worse in recent years and there are few feasible approaches to resolve this problem.Due to their high toxicity,prevalent existence and persistence in the environment,lead(Pb),mercury(Hg),cadmium(Cd),chromium(Cr) and arsenic(As) are commonly considered as the priority heavy metals which should be concerned and their emission should be controlled in China.This paper reviewed the pollution of heavy metals in China,focusing on the following four aspects:current status of heavy metal pollution in China,sources of heavy metals in China,toxicity and potential risk,and possible reduction strategies. | HE Bin YUN ZhaoJun SHI JianBo JIANG GuiBin | 2013 | Chinese Science Bulletin2013，58，2： | 114 |
| 2 | Developing the Science Product Algorithm Testbed for Chinese Next-Generation Geostationary Meteorological Satellites:Fengyun-4 Series显示文摘Fengyun-4A(FY-4A), the first of the Chinese next-generation geostationary meteorological satellites, launched in2016, offers several advances over the FY-2: more spectral bands, faster imaging, and infrared hyperspectral measurements. To support the major objective of developing the prototypes of FY-4 science algorithms, two science product algorithm testbeds for imagers and sounders have been developed by the scientists in the FY-4 Algorithm Working Group(AWG). Both testbeds, written in FORTRAN and C programming languages for Linux or UNIX systems, have been tested successfully by using Intel/g compilers. Some important FY-4 science products, including cloud mask, cloud properties, and temperature profiles, have been retrieved successfully through using a proxy imager, Himawari-8/Advanced Himawari Imager(AHI), and sounder data, obtained from the Atmospheric Infra Red Sounder, thus demonstrating their robustness. In addition, in early 2016, the FY-4 AWG was developed based on the imager testbed—a near real-time processing system for Himawari-8/AHI data for use by Chinese weather forecasters.Consequently, robust and flexible science product algorithm testbeds have provided essential and productive tools for popularizing FY-4 data and developing substantial improvements in FY-4 products. | Min MIN Chunqiang WU Chuan LI Hui LIU Na XU Xiao WU Lin CHEN Fu WANG Fenglin SUN Danyu QIN Xi WANG Bo LI Zhaojun ZHENG Guangzhen CAO Lixin DONG | 2017 | Journal of Meteorological Research2017，31，4： | 35 |
| 3 | Impacts of soil organic matter, pH and exogenous copper on sorption behavior of norfloxacin in three soils显示文摘Norfloxacin sorption and the factors (soil organic matter (SOM), pH, and exogenous copper (Cu) inffluencing the sorption were investigated in a black soil (soil B), a ?uvo-aquic soil (soil F), and a red soil (soil R). With increasing norfloxacin concentrations, sorption amount of norfloxacin increased in both the bulk soils and their SOM-removed soils, but the sorption capacity of SOM-removed soils was higher than that of their corresponding bulk soils, indicating that the process of norfloxacin sorption in soil was influenced by the soil properties including SOM. The sorption data in all bulk soils and SOM-removed soils were fitted to Freundlich and Langmuir models. The correlation coeflcients suggested that the experimental data fitted better to Freundlich equation than to Langmuir equation. Furthermore, the data from soil F and SOM-removed F could not be described by Langmuir equation. The norfloxacin sorption amount decreased in soil B and soil F, whereas it increased in soil R as solution pH increased. The maximum KD and KOC were achieved in soil R when the equilibrium solution pH was 6. The norfloxacin sorption was also influenced by the exogenous Cu2+, which depended on the soil types and Cu2+ concentrations. With increasing Cu2+ concentrations in solution, generally, sorption amount, KD and KOC for norfloxacin in soils increased and were up to a peak at 100 mg/L Cu2+, and then the sorption amount decreased regardless of norfloxacin levels. | ZHANG Jie LI Zhaojun GE Gaofei SUN Wanchun LIANG Yongchao WU Laosheng | 2009 | Journal of Environmental Sciences2009，21，5： | 21 |
| 4 | Toxicity of cadmium and its competition with mineral nutrients for uptake by plants:A review显示文摘Cadmium(Cd)is a toxic heavy metal occurring in the environment naturally and is also generated through various anthropogenic sources and acts as a pollutant.Human health is affected by Cd pollution in farmland soils because food is the main source of Cd intake in the non-smoking population.For crops,Cd toxicity may result from a disturbance in uptake and translocation of mineral nutrients and disturbance in plant metabolism,inhibiting plant growth and development.However,plants have Cd tolerance mechanisms,including restricted Cd uptake,decreased Cd root-to-shoot translocation,enhanced antioxidant enzyme activities,and increased production of phytochelatins.Furthermore,optimal supply of mineral nutrients is one of the strategies to alleviate the damaging effects of Cd on plants and to avoid its entry into the food chain.The emerging molecular knowledge contributes to understanding Cd uptake,translocation,and remobilization in plants.In this review,Cd toxicity and tolerance mechanisms,agricultural practices to minimize Cd accumulation,Cd competition with essential elements(calcium,copper,iron,zinc,and manganese),and genes associated with Cd uptake are discussed in detail,especially regarding how these mineral nutrients and genes play a role in decreasing Cd uptake and accumulation in crop plants. | Shiyu QIN Hongen LIU Zhaojun NIE Zed RENGEL Wei GAO Chang LI Peng ZHAO | 2020 | Pedosphere2020，30，2： | 20 |

| 6 | Bayesian Reliability Modeling and Assessment Solution for NC Machine Tools under Small-sample Data显示文摘Although Markov chain Monte Carlo(MCMC) algorithms are accurate, many factors may cause instability when they are utilized in reliability analysis; such instability makes these algorithms unsuitable for widespread engineering applications. Thus, a reliability modeling and assessment solution aimed at small-sample data of numerical control(NC) machine tools is proposed on the basis of Bayes theories. An expert-judgment process of fusing multi-source prior information is developed to obtain the Weibull parameters' prior distributions and reduce the subjective bias of usual expert-judgment methods. The grid approximation method is applied to two-parameter Weibull distribution to derive the formulas for the parameters' posterior distributions and solve the calculation difficulty of high-dimensional integration. The method is then applied to the real data of a type of NC machine tool to implement a reliability assessment and obtain the mean time between failures(MTBF). The relative error of the proposed method is 5.8020×10-4 compared with the MTBF obtained by the MCMC algorithm. This result indicates that the proposed method is as accurate as MCMC. The newly developed solution for reliability modeling and assessment of NC machine tools under small-sample data is easy, practical, and highly suitable for widespread application in the engineering field; in addition, the solution does not reduce accuracy. | YANG Zhaojun KAN Yingnan CHEN Fei XU Binbin CHEN Chuanhai YANG Chuangui | 2015 | Chinese Journal of Mechanical Engineering2015，28，6： | 16 |

| 8 | Micro-light-emitting diodes with quantum dots in display technology显示文摘Micro-light-emitting diodes(μ-LEDs)are regarded as the cornerstone of next-generation display technology to meet the personalised demands of advanced applications,such as mobile phones,wearable watches,virtual/augmented reality,micro-projectors and ultrahigh-definition TVs.However,as the LED chip size shrinks to below 20μm,conventional phosphor colour conversion cannot present sufficient luminance and yield to support highresolution displays due to the low absorption cross-section.The emergence of quantum dot(QD)materials is expected to fill this gap due to their remarkable photoluminescence,narrow bandwidth emission,colour tuneability,high quantum yield and nanoscale size,providing a powerful full-colour solution for μ-LED displays.Here,we comprehensively review the latest progress concerning the implementation of μ-LEDs and QDs in display technology,including μ-LED design and fabrication,large-scale μ-LED transfer and QD full-colour strategy.Outlooks on QD stability,patterning and deposition and challenges of μ-LED displays are also provided.Finally,we discuss the advanced applications of QD-based μ-LED displays,showing the bright future of this technology. | Zhaojun Liu Chun-Ho Lin Byung-Ryool Hyun Chin-Wei Sher Zhijian Lv Bingqing Luo Fulong Jiang Tom Wu Chih-Hsiang Ho Hao-Chung Kuo Jr-Hau He | 2020 | Light(Science & Applications)2020，9，1： | 12 |
| 9 | (E)-Nerolidol is a volatile signal that induces defenses against insects and pathogens in tea plants显示文摘Plants release large amounts of volatile organic compounds(VOCs)in response to attackers.Several VOCs can serve as volatile signals to elicit defense responses in undamaged tissues and neighboring plants,but many questions about the ecological functions of VOCs remain unanswered.Tea plants are impacted by two harmful invaders,the piercing herbivore Empoasca(Matsumurasca)onukii Matsuda and the pathogen Colletotrichum fructicola.To determine the VOC signals in tea,we confirmed CsOPR3 as a marker gene and set up a rapid screening method based on a 1.51 kb CsOPR3 promoter fused with aβ-glucuronidase(GUS)reporter construct(OPR3p::GUS)in Arabidopsis.Using this screening system,a terpenoid volatile(E)-nerolidol was identified as a potent signal that elicits plant defenses.The early responses triggered by(E)-nerolidol included the activation of a mitogen-activated protein kinase and WRKY,an H2O2 burst,and the induction of jasmonic acid and abscisic acid signaling.The induced plants accumulated high levels of defenserelated chemicals,which possessed broad-spectrum anti-herbivore or anti-pathogen properties,and ultimately triggered resistance against Empoasca onukii and Colletotrichum fructicola in tea.We propose that these findings can supply an environmentally friendly management strategy for controlling an insect pest and a disease of tea plants. | Shenglong Chen Liping Zhang Xiaoming Cai Xin Li Lei Bian Zongxiu Luo Zhaoqun Li Zongmao Chen Zhaojun Xin | 2020 | Horticulture Research2020，7，1： | 12 |

| 11 | Artificial intelligence in drug design显示文摘Thanks to the fast improvement of the computing power and the rapid development of the computational chemistry and biology,the computer-aided drug design techniques have been successfully applied in almost every stage of the drug discovery and development pipeline to speed up the process of research and reduce the cost and risk related to preclinical and clinical trials.Owing to the development of machine learning theory and the accumulation of pharmacological data, the artificial intelligence(AI) technology, as a powerful data mining tool, has cut a figure in various fields of the drug design, such as virtual screening,activity scoring, quantitative structure-activity relationship(QSAR) analysis, de novo drug design, and in silico evaluation of absorption, distribution, metabolism, excretion and toxicity(ADME/T) properties. Although it is still challenging to provide a physical explanation of the AI-based models, it indeed has been acting as a great power to help manipulating the drug discovery through the versatile frameworks. Recently, due to the strong generalization ability and powerful feature extraction capability,deep learning methods have been employed in predicting the molecular properties as well as generating the desired molecules,which will further promote the application of AI technologies in the field of drug design. | Feisheng Zhong Jing Xing Xutong Li Xiaohong Liu Zunyun Fu Zhaoping Xiong Dong Lu Xiaolong Wu Jihui Zhao Xiaoqin Tan Fei Li Xiaomin Luo Zhaojun Li Kaixian Chen Mingyue Zheng Hualiang Jiang | 2018 | Science China(Life Sciences)2018，61，10： | 10 |
| 12 | Comparative analysis of the complete chloroplast genome among Prunus mume,P.armeniaca,and P.salicina显示文摘Prunus mume Sieb.et Zucc.,P.armeniaca L.,and P.salicina L.are economically important fruit trees in temperate regions.These species are taxonomically perplexing because of shared interspecific morphological traits and variation,which are mainly attributed to hybridization.The chloroplast is cytoplasmically inherited and often used for evolutionary studies.We sequenced the complete chloroplast genomes of P.mume,P.armeniaca,and P.salicina using Illumina sequencing followed by de novo assembly.The three chloroplast genomes exhibit a typical quadripartite structure with conserved genome arrangement,structure,and moderate divergence.The lengths of the genomes are 157,815,157,797,and 157,916 bp,respectively.The length of the large single-copy region(LSC)region is 86,113,86,283,and 86,122 bp,and the length of the SSC region is 18,916,18,734,and 19,028 bp;the IR region is 26,393,26,390,and 26,383 bp,respectively.Each of the three chloroplast genomes encodes 133 genes,including 94 protein-coding,31 tRNA,and eight rRNA genes.Differential gene analysis for the three species revealed that trnY-ATA is a unique gene in P.armeniaca;in contrast,the gene trnI-TAT is only present in P.mume and P.salicina,though the position of the gene in these chloroplast genomes differs.Further comparative analysis of the complete chloroplast genome sequences revealed that the ORF genes and the sequences of linked regions rps16 and atpA,atpH and atpI,trnc-GCA and psbD,ycf3 and atpB,and rpL32 and ndhD are significantly different and may be used as molecular markers in taxonomic studies.Phylogenetic evolution analysis of the three species suggests that P.mume has a closer genetic relationship to P.armeniaca than to P.salicina. | Song Xue Ting Shi Wenjie Luo Xiaopeng Ni Shahid Iqbal Zhaojun Ni Xiao Huang Dan Yao Zhijun Shen Zhihong Gao | 2019 | Horticulture Research2019，6，1： | 10 |
| 13 | High-speed image reconstruction for optically sectioned,super-resolution structured illumination microscopy显示文摘Super-resolution structured illumination microscopy(SR-SIM)is an outstanding method for visualizing the subcellular dynamics in living cells.To date,by using elaborately designed systems and algorithms,SR-SIM can achieve rapid,optically sectioned,SR observation with hundreds to thousands of time points.However,real-time observation is still out of reach for most SIM setups as conventional algorithms for image reconstruction involve a heavy computing burden.To address this limitation,an accelerated reconstruction algorithm was developed by implementing a simplified workflow for SR-SIM,termed joint space and frequency reconstruction.This algorithm results in an 80-fold improvement in reconstruction speed relative to the widely used Wiener-SIM.Critically,the increased processing speed does not come at the expense of spatial resolution or sectioning capability,as demonstrated by live imaging of microtubule dynamics and mitochondrial tubulation. | Zhaojun Wang Tianyu Zhao Huiwen Hao Yanan Cai Kun Feng Xue Yun Yansheng Liang Shaowei Wang Yujie Sun Piero RBianco Kwangsung Oh Ming Lei | 2022 | Advanced Photonics2022，4，2： | 9 |
| 14 | Recent progress in rechargeable alkali metal-air batteries显示文摘Rechargeable alkali metal-air batteries are considered as the most promising candidate for the power source of electric vehicles(EVs) due to their high energy density. However, the practical application of metal-air batteries is still challenging. In the past decade, many strategies have been purposed and explored, which promoted the development of metal-air batteries. The reaction mechanisms have been gradually clarified and catalysts have been rationally designed for air cathodes. In this review, we summarize the recent development of alkali metal-air batteries from four parts: metal anodes, electrolytes, air cathodes and reactant gases, wherein we highlight the important achievement in this filed. Finally problems and prospective are discussed towards the future development of alkali metal-air batteries. | Xin Zhang Xin-Gai Wang Zhaojun Xie Zhen Zhou | 2016 | Green Energy & Environment2016，1，1： | 9 |
| 15 | Astragalus membranaceus reduces free radical mediated injury to renal tubules in rabbits receiving high energy shock waves显示文摘Background Recent studies have revealed the important role of free radicals in renal damage induced by high energy shock waves (HESW) This study aimed at investigating the effects of Astragalus membranaceus , a traditional Chinese medicinal herb, on free radical mediated HESW induced damage to renal tubules in a live rabbit model Methods Forty five healthy male New Zealand white rabbits were randomly divided into three groups: control group ( n =15), sham group ( n =15), and herb treated group ( n =15) Three days prior to HESW application, the controls received verapamil (0 4 mg/kg), the shams received physiological saline (20 ml), and the herb treated animals received Astragalus membranaceus (2 4 g/kg) intravenously HESW (1500 shocks, 18kV) was applied to the right kidneys of all anesthetized rabbits We measured superoxide dismutase (SOD) and malondialdehyde (MDA) levels before and after shock treatment in blood and kidney homogenates Histopathological changes were also observed Results MDA levels increased and SOD activity decreased significantly in the sham group ( P <0 05 for both) after shock treatment MDA levels showed a much less increase in the controls ( P <0 05) and did not increase to statistically significant levels in the group receiving Astragalus membranaceus ( P >0 05) SOD values were significantly higher in the controls than in the shams ( P <0 05) By contrast, SOD levels recovered rapidly in the rabbits receiving Astragalus membranaceus , reaching a nadir within 24 hours, and returning to baseline more quickly than in control and sham rabbits ( P <0 05) Histopathological examinations showed that renal tubular damage in the controls was less severe than in the shams, while damage in the Astragalus membranaceus group was even more mild, with rapid recovery in comparison with the controls Conclusion This study provides preliminary evidence indicating that Astragalus membranaceus has strong protective effects on free radical mediated renal tubular damage induced by HESW and that these effects are superior to the effects of | SHENGBin-wu CHENXing-fa ZHAOJun HEDa-lin NANXun-yi | 2005 | Chinese Medical Journal2005，，1： | 8 |
| 16 | Accuracy assessments and uncertainty analysis of spatially explicit modeling for land use/cover change and urbanization:A case in Beijing metropolitan area显示文摘Spatially explicit modeling plays a vital role in land use/cover change and urbanization research as well as resources management;however,current models lack proper validation and fail to incorporate uncertainty into the formulation of model predictions.Consequently,policy makers and the general public may develop opinions based on potentially misleading research,which fails to allow for truly informed decisions.Here we use an uncertainty strategy of spatially explicit modeling combined with the series statistic of Kappa index for location and quantity to estimate the uncertainty of future predications and to determine model accuracy.We take the Beijing metropolitan area as an example to demonstrate the uncertainty in extrapolations of predictive land use change and urban sprawl with spatially explicit modeling at multiple resolutions.The sensitivity of scale effects is also discussed.The results show that an improvement in specification of location is more helpful in increasing accuracy as compared to an improvement in the specification of quantity at fine spatial resolutions.However,the spatial scale has great effects on modeling accuracy and correct due to chance tends to increase as resolution becomes coarser.The results allow us to understand the uncertainty when using spatially explicit models for land-use change or urbanization estimates. | ZHANG Jie ZHOU YinKang LI RenQiang ZHOU ZhaoJun ZHANG LiQuan SHI QingDong PAN XiaoLing | 2010 | Science China Earth Sciences2010，53，2： | 8 |
| 17 | Design and optimization of seedling-feeding device for automatic maize transplanter with maize straw seedling-sprouting tray显示文摘This research aimed to solve current problems in the process of maize transplanting in China such as large labor intensity,low working efficiency and poor quality.On the basis of the structure of a seedling-sprouting tray made of maize straw and the agronomic requirements of maize production,this study developed a new feeding device for such a sprouting tray,determined the dimensions of the key components in a virtual environment via Solid Edge software and obtained optimal working parameters in combination with Matlab.Some tests on field validation and maize production were conducted as well.The test results showed the importance of the working parameters on an upright degree in descending order(as well as the best working parameters)to be the vertical angle of seedling planting(13.14°),the forward speed of locomotion(0.57 m/s),and the horizontal angle of the seedling box(22.5°).The standard deviation of the field validation was 6.04%,which was within the allowable range to meet the requirements of maize transplanting.Compared with maize transplanting machines(and manual transplanting operations)on the current market,the labor inputs,as well as the rates of spacing and upright degree qualification,omitted planting and the yield using the new feeding device for automatic transplanter with maize straw seedling-sprouting trays increased 0(6.9%),0(3.1%),0(4.5%)and 0(−1.0%),respectively;whereas,the manufacturing cost was reduced by 35.5%.The results can provide a technical basis and reference for subsequent development of automatic transplanters with maize straw seedling-sprouting trays. | Zhang Wei Niu Zhaojun Li Lianhao Hou Yongrui | 2015 | International Journal of Agricultural and Biological Engineering2015，8，6： | 8 |
| 18 | System Entropy and Its Application in Feature Selection显示文摘Feature selection is always an important issue in the research on data mining technologies. However, the problem of optimal feature selection is NP hard. Therefore, heuristic approaches are more practical to actual learning systems. Usually, that kind of algorithm selects features with the help of a heuristic metric compactum to measure the relative importance of features in a learning system. Here a new notion of ‘system entropy’ is described in terms of rough set theory, and then some of its algebraic characteristics are studied. After its intrinsic value biase is effectively counteracted, the system entropy is applied in BSE, a new heuristic algorithm for feature selection. BSE is efficient, whose time complexity is lower than that of analogous algorithms; BSE is also effective, which can produce the optimal results in the mini-feature biased sense from varieties of learning systems. Besides, BSE is tolerant and also flexible to the inconsistency of a learning system, consequently able to elegantly handle data noise in the learning system. | ZHAOJun WUZhong-fu | 2004 | The Journal of China Universities of Posts and Telecommunications2004，11，1： | 7 |
| 19 | Sedimentary Characteristics of the Cretaceous in the Songliao Basin显示文摘The rupture of the lithosphere in Late Jurassic brought about the eruption of basaltic magma in the Songliao Basin. The evolution of the basin in Cretaceous progressed through six stages: pre-rift doming, extensional fracturing, fault subsidence, fault downwarping, downwarping and shringkage, resulting in the deposition of terrstrial facies nearly 10,000 m thick. There are different depositional sequences in these stages: the depositional period of the Early Cretaceous Shahezi and Yincheng Formations is the development stage of the down-faulted basin, forming a volcanic rock-alluvial fan-fan delta-lacustrine (intercalated with episodic turbidites)-swamp facies sequences; the period of the Early Cretaceous Dengluku Formation is the transformation stage of fault subsidence into fault downwarping of the basin, forming a sequence mainly of alluvial plain-lacustrine facies; the depositional period of the Early Cretaceous Quantou Formation-Late Cretaceous Nenjiang Formation is the downwarping stage of the basin, forming an alluvial plain-delta-lacustrine facies sequence; the period of the Late Cretaceous Sifangtai Formation-Mingshui Formation is the shringkage stage of the basin, forming again a sequence mainly of alluvial plain-alluvial fan and small relict lacustrine facies. These vertical depositional sequences fully display the sedimentary characteristics of a failed continental rift basin. Many facts indicate that the two large-scale lake invasions, synchronous with the global rise of sea level, which took place in the downwarping stage of the basin development, led to the connection between the lake and sea. | Liu Zhaojun, Wang Dongpo, Liu Li, Liu Wanzhu, Wang Pujun, Du Xiaodi and Yang Guang Changchun University of Earth Sciences, Changchun, Jilin Sun Sheping | 1993 | Acta Geologica Sinica(English Edition)1993，67，2： | 7 |

The mean outdoor temperature is about-10. 0 ℃ during the winter in Harbin,while the indoor air temperature is often above24 ℃. How does the indoor environment influence human thermal comfort and adaptation in such an overheated environment?A combined approach of spot-reading measurements and occupant interview s w as adopted in nine residential buildings of five communities during the heating period in 2013-2014. Tw enty residents w ere chosen as respondents. Totally 308 valid questionnaires w ere collected. The heating periods w ere separated into three phases based on the outdoor temperature.The results show that the mean indoor air temperatures in theearly-,mid-and late-heating periods w ere 23. 6 ℃,24. 3 ℃and 25. 0 ℃,respectively,w hich w ere larger than or close to the upper limit recommended by thermal comfort standards, and slightly higher than the related thermal neutral temperatures. With the heating process,the mean clothing insulation of residents decreased. Opening w indow s and reducing clothing w ere mainly taken by the residents to adapt to the overheated environment.The thermal neutral temperature has an upw ard tendency w ith the increasing indoor air temperature. On the other hand,overheating in residential buildings w ould make residents open w indow s,w hich may cause thermal discomfort and energy w aste. Therefore,the low er limit of the comfort indoor air temperature range should be suggested as the heating temperature,w hich could fully arouse residents' adaptation and achieve sustainable building designs. | Zhaojun Wang Yuchen Ji Jing Ren 侯恩哲 | 2017 | 建筑节能2017，45，7： | 6 |
