| 1 | Mechanism and control of lake eutrophication显示文摘A review about lake naturally eutrophi- cating, the internal loading of nutrients from lake sediment as well as the mechanism of algal blooms and the control practices was made, especially the eutrophication problem of shallow lakes since sev- enty percent of fresh water lakes in China are shallow lakes. It was found that shallow lakes are apt toward eutrophication than deep lakes. Without any influ- ences of human activity, shallow lakes in the middle and lower reaches of Yangtze River are still easily eutrophicated, which may be owing to the effects of flood in this area. In shallow lakes, sediments are frequently disturbed by wind-wave and resuspended, which result in huge nutrients release to overlying water. This may be the major reason for higher in- ternal loading of nutrients in shallow lakes than in deep lakes. Algal bloom is an extreme response of lake ecosystem to the eutrophication. Appearance of algal blooms is related to physical condition of lakes, such as underwater radiation (or transparency), temperature, and hydrodynamic conditions, or related to geochemical conditions of lakes, like concentra- tions of nutrients and ratio of nitrogen to phosphorus, as well as the physiological advantage of cyanobac- teria such as vacuole for moving towards the radiant energy-rich zone and the mycosporine-like amino acids (MAAs) for resisting the harm of ultraviolet ra- diation. In shallow lakes, these advantages of cyanobacteria are favorable in the competition than in deep lakes. Also being the shallowness, it is more difficult to reduce nutrient loading and to control algae blooms in shallow lakes. For the control of eutrophi- cation, people should follow the sequence from pollution sources control, ecological restoration tocatchment management. To control the internal nu- trient release, physical, chemical, biological tech- niques, and even bionic techniques could be selected. The idea of ecological restoration for a eutrophic lake is to shift the ecosystem from phytoplankton-domi- nant state to macrophyte-dominant state. To realize the shift of ecosystem state, environmental condition improvement is the fundamental work. Nowadays, we should do more work on environmental condition improvement than on planting of macrophytes since we are lack of the knowledge about the relationship between macrophyte and lake ecosystem. Empha- sizing the macrophyte planting, therefore, has blind- ness at present. Because all lakes have different characteristics of environment and ecosystem, ap- plicable lake harness techniques should be selected based on the distinct ecosystem types and environ- mental problems. | QIN Boqiang YANG Liuyan CHEN Feizhou ZHU Guangwei ZHANG Lu CHEN Yiyu | 2006 | Chinese Science Bulletin2006，51，19： | 38 |

| 4 | Calculation of the end-rolling strength in Q235strip steel by the alloying electron structure parameters显示文摘Combined with the phase transformations in rolling,the phase configuration,the tensile strength,and the yield strength with different terminal rolling grain sizes in Q235strip steel have been theoretically calculated using the covalent electron number(n A )of the strongest bond in phase cells and the interface electron density difference(Δρ)in alloys.The calculated results agree well with the results of real production.Therefore,the calculation method of terminal rolling tensile and yield strength in the non-quenched-tem-pered steel containing pearlite is given by the alloying electron structure parameters. | LIUZhilin LINCheng LIUYan GUOYanchang | 2005 | Progress in Natural Science:Materials International2005，15，3： | 18 |
| 5 | Surplus Space Method: A New Numerical Model for Prediction of Shallow-seated Magmatic Bodies显示文摘Based on the data of field measurement and drilling in the Tongling area, a series of numerical simulations are carried out by using the 'Surplus Space Method' (SSM), which is first put forward in this paper and applied to predict the shallow-seated magmatic bodies. The results of the numerical simulations show the existence and the 3-D shape of a conical magmatic structure at a depth of-1000 m beneath the center of the area: its top offsets southwards and bifurcates to several branches, while its lower part stretches northeastwards and contracts rapidly to a point at about -1000 m depth.This point is reckoned to be a 'sink' of magma system, transferring ore materials and heat energy from the deep magma chamber to the sub-surface apophyses. The preliminary application of the SSM proves that it may be developed as a new detection means for determining the existence of shallow-seated magmatic bodies and analyzing their three-dimensional features. | DENGJun HUANGDinghua WANGQingfeit WANLi YAOLingqing GAOBangfei LiuYan | 2004 | Acta Geologica Sinica(English Edition)2004，78，6： | 8 |
| 6 | Synthetic biology: From the first synthetic cell to see its current situation and future development显示文摘Synthetic biology is an emerging field,which,since its birth,has shown great value and potential in many fields including medicine,energy,environment and agriculture.It is also important for the study of the origin and evolution of life.Since the publication of the first synthetic cell in May,2010,synthetic biology again attracts high attention and leads to extensive discussions all over the world.There have been a number of researches and achievements on synthetic biology in the United States and European countries.While in China,so far there is no systematic research on synthetic biology.In order to promote the development of this new discipline in China,we organized this review to systematically introduce the concept and research content of synthetic biology,summarize the achievements,and investigate the current situation in both China and abroad.We also analyzed the opportunities and challenges in synthetic biology,and looked forward to the future development of synthetic biology,especially its future development in China. | ZHANG LiuYan CHANG SuHua WANG Jing | 2011 | Chinese Science Bulletin2011，56，3： | 8 |
| 7 | Characteristics of microbial community involved in early biofilms formation under the influence of wastewater treatment plant effluent显示文摘Effluents from wastewater treatment plants(WWTPs) containing microorganisms and residual nutrients can influence the biofilm formation. Although the process and mechanism of bacterial biofilm formation have been well characterized, little is known about the characteristics and interaction of bacteria, archaea and eukaryotes in the early colonization, especially under the influence of WWTP effluent. The aim of this study was to characterize the important bacterial, archaeal and eukaryotic species in the early stage of biofilm formation downstream of the WWTP outlet. Water and biofilm samples were collected 24 and 48 hr after the deposition of bio-cords in the stream. Illumina Miseq sequencing of the 16 S and 18 S rDNA showed that, among the three domains, the bacterial biofilm community had the largest alpha and beta diversity. The early bacterial colonizers appeared to be 'biofilm-specific', with only a few dominant operational taxonomic units(OTUs) shared between the biofilm and the ambient water environment. Alpha-proteobacteria and Ciliophora tended to dominate the bacterial and eukaryotic communities, respectively, of the early biofilm already at 24 hr, whereas archaea played only a minor role during the early stage of colonization. The network analysis showed that the three domains of microbial community connected highly during the early colonization and it might be a characteristic of the microbial communities in the biofilm formation process where co-occurrence relationships could drive coexistence and diversity maintenance within the microbial communities. | Yuke Peng Jie Li Junling Lu Lin Xiao Liuyan Yang | 2018 | Journal of Environmental Sciences2018，30，4： | 6 |
| 8 | Expert consensus on regenerative endodontic procedures显示文摘Regenerative endodontic procedures(REPs)is a biologic-based treatment modality for immature permanent teeth diagnosed with pulp necrosis.The ultimate objective of REPs is to regenerate the pulp-dentin complex,extend the tooth longevity and restore the normal function.Scientific evidence has demonstrated the efficacy of REPs in promotion of root development through case reports,case series,cohort studies,and randomized controlled studies.However,variations in clinical protocols for REPs exist due to the empirical nature of the original protocols and rapid advancements in the research field of regenerative endodontics.The heterogeneity in protocols may cause confusion among dental practitioners,thus guidelines and considerations of REPs should be explicated.This expert consensus mainly discusses the biological foundation,the available clinical protocols and current status of REPs in treating immature teeth with pulp necrosis,as well as the main complications of this treatment,aiming at refining the clinical management of REPs in accordance with the progress of basic researches and clinical studies,suggesting REPs may become a more consistently evidence-based option in dental treatment. | Xi Wei Maobin Yang Lin Yue Dingming Huang Xuedong Zhou Xiaoyan Wang Qi Zhang Lihong Qiu Zhengwei Huang Hanguo Wang Liuyan Meng Hong Li Wenxia Chen Xiaoying Zou Junqi Ling | 2022 | International Journal of Oral Science2022，14，4： | 5 |
| 9 | Numerical simulation of turbulent combustion: Scientific challenges显示文摘Predictive simulation of engine combustion is key to understanding the underlying complicated physicochemical processes,improving engine performance,and reducing pollutant emissions.Critical issues as turbulence modeling,turbulence-chemistry interaction,and accommodation of detailed chemical kinetics in complex flows remain challenging and essential for highfidelity combustion simulation.This paper reviews the current status of the state-of-the-art large eddy simulation(LES)/probability density function(PDF)/detailed chemistry approach that can address the three challenging modelling issues.PDF as a subgrid model for LES is formulated and the hybrid mesh-particle method for LES/PDF simulations is described.Then the development need in micro-mixing models for the PDF simulations of turbulent premixed combustion is identified.Finally the different acceleration methods for detailed chemistry are reviewed and a combined strategy is proposed for further development. | REN ZhuYin LU Zhen HOU LingYun LU LiuYan | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，8： | 5 |

| 11 | Pathway-based analysis for genome-wide association studies of schizophrenia to provide new insight in schizophrenia study显示文摘Schizophrenia (SZ) is an inheritable complex mental disease. There have been several genome-wide association studies (GWASs) of SZ to identify novel genetic susceptibility factors. To further interpret SZ GWASs, pathway-based analysis (PBA), which considers the combined effect of variants and identifies pathways associated with traits, provides a feasible solution to discover the biological function and mechanism of SZ. Furthermore, to investigate the common pathways between SZ and bipolar disorder (BD) will help explore common mechanism between psychiatric phenotypes. We performed a PBA, called improved gene set enrichment analysis (i-GSEA), on 3 independent GWASs of SZ to identify pathways associated with SZ. The results were further compared to the BD-associated pathways identified by i-GSEA for 2 BD GWASs and from literature reports. Our analysis identified a highly statistically significant association between SZ and pathway 'substrate specific channel activity' in all 3 SZ GWASs (false discovery rate (FDR) < 0.05). This association has not been reported elsewhere before. This pathway was also identified by PBA for 2 independent BD GWASs. Our results suggest that pathway 'substrate specific channel activity' is statistically significantly associated with SZ, and SZ and BD share the common biological function and mechanism represented by this pathway. | ZHANG KunLin ZHANG LiuYan ZHANG WeiNa WANG Jing | 2011 | Chinese Science Bulletin2011，56，32： | 4 |
| 12 | Size-and temperature-dependent Young's modulus and size-dependent thermal expansion coefficient of nanowires显示文摘Nanowires(NWs) exhibit size-dependent mechanical properties due to the high surface/volume ratio, in which temperature also plays an important role. The surface eigenstress model is further developed here to quantitatively predict the size-dependent mechanical properties of NWs and results in analytic formulas. Molecular dynamics(MD) simulations are conducted to study the size-dependent mechanical of [100], [110] and [111] Ni and Si nanowires within the temperature range of 100–400 K and the MD results verify perfectly the newly developed surface eigenstress model. | SUN HongLiang CHEN LiuYan SUN Sheng ZHANG Tong-Yi | 2018 | Science China(Technological Sciences)2018，61，5： | 4 |
| 13 | Do green spaces affect the spatiotemporal changes of PM_(2.5) in Nanjing?显示文摘Introduction:Among the most dangerous pollutants is PM_(2.5),which can directly pass through human lungs and move into the blood system.The use of nature-based solutions,such as increased vegetation cover in an urban landscape,is one of the possible solutions for reducing PM_(2.5) concentration.Our study objective was to understand the importance of green spaces in pollution reduction.Methods:Daily PM_(2.5) concentrations were manually collected at nine monitoring stations in Nanjing over a 534-day period from the air quality report of the China National Environmental Monitoring Center(CNEMC)to quantify the spatiotemporal change of PM_(2.5) concentration and its empirical relationship with vegetation and landscape structure in Nanjing.Results:The daily average,minimum,and maximum PM_(2.5) concentrations from the nine stations were 74.0,14.2,and 332.0μg m^(−3),respectively.Out of the 534 days,the days recorded as“excellent”and“good”conditions were found mostly in the spring(30.7%),autumn(25.6%),and summer(24.5%),with only 19.2% of the days in the winter.High PM_(2.5) concentrations exceeding the safe standards of the CNEMC were recorded predominately during the winter(39.3-100.0%).Our hypothesis that green vegetation had the potential to reduce PM_(2.5) concentration was accepted at specific seasons and scales.The PM_(2.5) concentration appeared very highly correlated(R2>0.85)with green cover in spring at 1-2 km scales,highly correlated(R2>0.6)in autumn and winter at 4 km scale,and moderately correlated in summer(R2>0.4)at 2-,5-,and 6-km scales.However,a non-significant correlation between green cover and PM_(2.5) concentration was found when its level was>75μg m^(−3).Across the Nanjing urban landscape,the east and southwest parts had high pollution levels.Conclusions:Although the empirical models seemed significant for spring only,one should not devalue the importance of green vegetation in other seasons because the regulations are often complicated by vegetation,meteorological conditions,and human activities. | Jiquan Chen Liuyan Zhu Peilei Fan Li Tian Raffaele Lafortezza | 2016 | Ecological Processes2016，5，1： | 3 |

| 16 | Effect of Microstructure on Wear Behavior of Iron Aluminide Based Coatings显示文摘An experimental study has been carried out to investigate the effect of microstructure on sliding wear behavior of Fe-Al coatings and Fe-Al/WC composite coatings produced by high velocity arc spraying (HVAS) and cored wires. After heat treatment at 300°C, 450°C, 550°C, 650°C and 800°C, the microstructure of the coatings will be changed. The changes of microstructure have obvious effects on the microhardness of the coatings, which may be the most important factor influencing the coatings sliding wear behavior. After heat treated at 450°C-650°C, increasing of the amounts of iron aluminides (including Fe3Al and FeAl ) and dispersion strengthening of Fe2\V2C and Fe6W6C will lead to a rise of microhardness of the coatings. Increasing the microhardness through heat treatment would improve the sliding wear resistance of the iron aluminide based coatings coatings. | ZHUZi-xin LIUYan XUBin-shi ZHANGWei MAShi-ning | 2004 | 材料热处理学报2004，25，05B： | 2 |

| 20 | Effects of humic acids and microorganisms on decabromodiphenyl ether, 4,4′-dibromodiphenyl ether and anthracene transportation in soil显示文摘In this study, effects of humic acids (HA) and microorganisms on the migration of hydrophobic organic contaminants (HOCs), decabromodiphenyl ether (BDE-209), 4,4′-dibromodiphenyl ether (BDE-15) and anthracene, in soils were examined. More soil particles were dispersed into the colloidal phase (0.22-1 μm) in the presence of HA and/or microorganisms as a result of increased erosion and friction. The study suggested that PBDEs (BDE-209 and BDE-15) and anthracene in soils would be transported to other places by soil colloids with surface and underground water flow given the high concentrations of HA and microorganisms in the natural environment. | YU Sheng, ZOU Peng, ZHU Wei, YANG LiuYan, XIAO Lin, JIANG LiJuan, WANG XiaoLin, WU Jun & YUAN Ye State Key Laboratory of Pollution Control and Resource Reuse School of the Environment, Nanjing University, Nanjing 210093, China | 2010 | Science China Chemistry2010，53，4： | 2 |
