| 1 | Modeling study of regional severe hazes over mid-eastern China in January 2013 and its implications on pollution prevention and control显示文摘The Nested Air Quality Prediction Model System(NAQPMS)was used to investigate the temporal and spatial variations of PM2.5over tropospheric central eastern China in January 2013.The impact of regional transport and its implications on pollution prevention and control were also examined.Comparison between simulated and observed PM2.5showed NAQPMS was able to reproduce the evolution of PM2.5during heavy haze episodes.The results indicated that regional transport of PM2.5played an important role in regional haze episodes in the city cluster including Hebei,Beijing and Tianjin(HBT).The cross-city clusters transport outside HBT and transport among cities inside HBT contributed 20%–35%and 26%–35%of PM2.5as compared with local emission,in HBT respectively.To meet the Air Quality Standards for Grade II,90%,90%and65%of emissions would have to be cut down in Hebei,Tianjin and Beijing,if non-control strategy was taken in the surrounding city clusters of HBT.This implicated that control of emissions in one city cluster is not sufficient to reduce regional haze events,and joint efforts among city clusters are essential.Besides regional transports,two-way feedback between boundary-layer evolution and PM2.5also significantly contributed to the formation of heavy hazes,which contributed 30%of monthly average PM2.5concentration in HBT. | WANG ZiFa LI Jie WANG Zhe YANG WenYi TANG Xiao GE BaoZhu YAN PinZhong ZHU LiLi CHEN XueShun CHEN HuanSheng WAND Wei LI JianJun LIU Bing WANG XiaoYan WAND Wei ZHAO YiLin LU Ning SU DeBin | 2014 | Science China Earth Sciences2014,57,1: | 106 |
| 2 | Transplantation of UC-MSCs on collagen scaffold activates follicles in dormant ovaries of POF patients with long history of infertility显示文摘Premature ovarian failure(POF) is a refractory disease for clinical treatment with the goal of restoring fertility. In this study,umbilical cord mesenchymal stem cells on a collagen scaffold(collagen/UC-MSCs) can activate primordial follicles in vitro via phosphorylation of FOXO3 a and FOXO1. Transplantation of collagen/UC-MSCs to the ovaries of POF patients rescued overall ovarian function, evidenced by elevated estradiol concentrations, improved follicular development, and increased number of antral follicles. Successful clinical pregnancy was achieved in women with POF after transplantation of collagen/UC-MSCs or UC-MSCs. In summary, collagen/UC-MSC transplantation may provide an effective treatment for POF. | Lijun Ding Guijun Yan Bin Wang Lu Xu Yan Gu Tong Ru Xiaoying Cui Lei Lei Jingyu Liu Xiaoqiang Sheng Bin Wang Chunxue Zhang Yanjun Yang Ruiwei Jiang Jianjun Zhou Na Kong Feifei Lu Huaijun Zhou Yannan Zhao Bing Chen Yali Hu Jianwu Dai Haixiang Sun | 2018 | Science China(Life Sciences)2018,61,12: | 43 |

| 4 | Preliminary Scientific Results of Chang'E-1 Lunar Orbiter:Based on Payloads Detection Data in the First Phase显示文摘Chang'E-1 lunar Orbiter was launched by Long March 3A rocket from Xichang Satel-lite Launch Center at 18:05BT(Beijing Time) Oct.24,2007.It is the first step of its ambitious three-stage moon program,a new milestone in the Chinese space exploration history.The primary science objectives of Chang'E-1 lunar orbiter are to obtain three-Dimension(3D) stereo images of the lunar surface,to analyze the distribution and abundance of elements on the surface,to investigate the thickness of lunar soil,evaluate helium-3 resources and other characteristics,and to detect the space environment around the moon.To achieve the above four mission objectives,eight sets of scientific instruments are chosen as the payloads of the lunar orbiter,including a CCD stereo camera(CCD),a Sagnac-based interferometer spectrometer(ⅡM),a Laser Altimeter(LAM),a Microwave Radiometer(MRM),a Gamma-Ray Spectrometer(GRS),an X-ray spectrometer(XRS),a High-Energy Particle Detector(HPD),and two Solar Wind Ion Detectors(SWID).The detected data of the payloads show that all payloads work well.This paper introduces the status of payloads in the first phase and preliminary scientific results. | OUYANG Ziyuan JIANG Jingshan LI Chunlai SUN Huixian ZOU Yongliao LIU Jianzhong LIU Jianjun ZHAO Baochang REN Xin YANG Jianfeng ZHANG Wenxi WANG Jianyu MOU Lingli CHANG Jin ZHANG Liyan WANG Huanyu LI Yongquan ZHANG Xiaohui ZHENG Yongchun WANG Shijin BIAN Wei | 2008 | 空间科学学报2008,28,5: | 24 |
| 5 | Changes in global potential vegetation distributions from 1911 to 2000 as simulated by the Comprehensive Sequential Classification System approach显示文摘Vegetation classification models play an important role in studying the response of the terrestrial ecosystem to global climate change. In this paper, we study changes in global Potential Natural Vegetation (PNV) distributions using the Comprehensive Sequential Classification System (CSCS) approach, a technique that combines geographic information systems. Results indicate that on a global scale there are good agreements among maps produced by the CSCS method and the globally well-accepted Holdridge Life Zone (HLZ) and BIOME4 PNV models. The potential vegetation simulated by the CSCS approach has 6 major latitudinal zones in the northern hemisphere and 2 in the southern hemisphere. In mountainous areas it has obvious altitudinal distribution characteristics due to topographic effects. The distribution extent for different PNV classes at various periods has different characteristics. It had a decreasing trend for the tundra and alpine steppe, desert, sub-tropical forest and tropical forest categories, and an increasing trend for the temperate forest and grassland vegetation categories. The simulation of global CSCS-based PNV classes helps to understand climate-vegetation relationships and reveals the dynamics of potential vegetation distributions induced by global changes. Compared with existing statistical and equilibrium models, the CSCS approach provides similar mapping results for global PNV and has the advantage of improved simulation of grassland classes. | LIANG TianGang FENG QiSheng CAO JianJun XIE HongJie LIN HuiLong ZHAO Jun REN JiZhou | 2012 | Chinese Science Bulletin2012,57,11: | 23 |
| 6 | Cardiotoxicity of 5-fluorouracil and capecitabine in Chinese patients: a prospective study显示文摘Background:5-Fluorouracil(5-FU)and capecitabine-associated cardiotoxicity ranging from asymptomatic electro-cardiography(ECG)abnormalities to severe myocardial infarction has been reported in a number of studies,but such cardiotoxicity in Chinese patients with malignant diseases has not been investigated to date.In the present study,we aimed to prospectively evaluate the incidence rates and clinical manifestations of 5-FU-and capecitabine-associated cardiotoxicity in cancer patients recruited from multiple centers in China.Methods:Among the 527 patients who completed the study,196 received 5-FU-based chemotherapy and 331 received capecitabine-based chemotherapy as either first-line or adjuvant therapy.Adverse events were reported during the treatment and up to 28 days of follow-up.Outcome measures included ECG,myocardial enzymes,cardiac troponin,brain natriuretic peptide and echocardiography.Univariate analysis and logistic regression were performed for subgroup analysis and identification of significant independent variables that are associated with cardiotoxicity of both agents.Results:In total,161 of 527 patients(30.6%)experienced cardiotoxicity.The incidence rate of cardiotoxicity was 33.8%(112/331)in the capecitabine group,which was significantly higher than the rate of 25%(49/196)in the 5-FU group(P=0.0042).110/527 patients(20.9%)suffered arrhythmia,105/527(19.9%)developed ischemic changes,while only 20/527 patients(3.8%)presented heart failure and 6/527 patients(1.1%)had myocardial infarction.Pre-existing cardiac disease,hypertension,capecitabine-based chemotherapy and duration of treatment were identified as sig-nificant risk factors associated with cardiotoxicity.The odds ratio were 15.7(prior history of cardiac disease versus no history),1.86(capecitabine versus 5-FU),1.06(5-8 versus 1-4 chemotherapy cycles)and 1.58(hypertension versus no hypertension),respectively.Conclusions:Cardiotoxicity induced by fluoropyrimidines in the Chinese population may be underestimated in clini-cal practice.Close monitoring of patients is recommended,especially for those patients at high risk for cardiotoxicity.Possible risk factors are duration of treatment,capecitabine-based chemotherapy,pre-existing cardiac diseases and hypertension.Trial registration This study was initiated on January 22,2014 and has been retrospectively registered with the registra-tion number ChiCTR1800015434 . | Jianjun Peng Chao Dong Chang Wang Weihua Li Hao Yu Min Zhang Qun Zhao Bo Zhu Jun Zhang Wenliang Li Fenghua Wang Qiong Wu Wenhao Zhou Ying Yuan Meng Qiu Gong Chen | 2018 | Cancer Communications2018,38,1: | 23 |

| 8 | Effects of overlying water aeration on phosphorus fractions and alkaline phosphatase activity in surface sediment显示文摘Microbial activity may influence phosphorus (P) deposit and release at the water sediment interface.The properties of DO (dissolved oxygen),pH,P fractions (TP,Ca-P,Fe-P,OP,IP),and APA (alkaline phosphatase activity) at the water sediment interface were measured to investigate microbial activity variations in surface sediment under conditions of two-month intermittent aeration in overlying water.Results showed that DO and TP of overlying water increased rapidly in the first week and then decreased gradually after 15 day of intermittent aeration.Microorganism metabolism in surface sediment increased pH and decreased DO and TP in the overlying water.After two-month intermittent aeration,APA and OP from surface sediment (0-2 cm) were both significantly higher than those from bottom sediment (6-8 cm) (p < 0.05),and surface sediment Fe-P was transferred to OP during the course of microorganism reproduction on the surface sediment.These results suggest that microbial activity and microorganism biomass from the surface sediment were higher than those from bottom sediment after two-month intermittent aeration in the overlying water. | Jianjun Chen Shaoyong Lu Yikun Zhao Wei Wang Minsheng Huang | 2011 | Journal of Environmental Sciences2011,23,2: | 20 |
| 9 | Poxue Huayu and Tianjing Busui Decoction for cerebral hemorrhage Upregulation of neurotrophic factor expression显示文摘This study established a rat model of cerebral hemorrhage by injecting autologous anticoagulated blood.Rat models were intragastrically administered 5,10,20 g/kg Poxue Huayu and Tianjing Busui Decoction,supplemented with Hirudo,raw rhubarb,raw Pollen Typhae,gadfly,Fructrs Trichosanthis,Radix Notoginseng,Rhizoma Acori Talarinowii,and glue of tortoise plastron,once a day,for 14 consecutive days.Results demonstrated that brain water content significantly reduced in rats with cerebral hemorrhage,and intracerebral hematoma volume markedly reduced after treatment.Immunohistochemical staining revealed that brain-derived neurotrophic factor,tyrosine kinase B and vascular endothelial growth factor expression noticeably increased around the surrounding hematoma.Reverse transcription-PCR revealed that brain-derived neurotrophic factor and tyrosine kinase B mRNA expression significantly increased around the surrounding hematoma.Neurologic impairment obviously reduced.These results indicated that Poxue Huayu and Tianjing Busui Decoction exert therapeutic effects on cerebral hemorrhage by upregulating the expression of brain-derived neurotrophic factor. | Jixiang Ren Xiangyu Zhou Jian Wang Jianjun Zhao Pengguo Zhang | 2013 | Neural Regeneration Research2013,8,22: | 19 |
| 10 | High-speed femtosecond laser plasmonic lithography and reduction of graphene oxide for anisotropic photoresponse显示文摘Micro/nanoprocessing of graphene surfaces has attracted significant interest for both science and applications due to its effective modulation of material properties,which,however,is usually restricted by the disadvantages of the current fabrication methods.Here,by exploiting cylindrical focusing of a femtosecond laser on graphene oxide(GO)films,we successfully produce uniform subwavelength grating structures at high speed along with a simultaneous in situ photoreduction process.Strikingly,the well-defined structures feature orientations parallel to the laser polarization and significant robustness against distinct perturbations.The proposed model and simulations reveal that the structure formation is based on the transverse electric(TE)surface plasmons triggered by the gradient reduction of the GO film from its surface to the interior,which eventually results in interference intensity fringes and spatially periodic interactions.Further experiments prove that such a regular structured surface can cause enhanced optical absorption(>20%)and an anisotropic photoresponse(~0.46 ratio)for the reduced GO film.Our work not only provides new insights into understanding the laser-GO interaction but also lays a solid foundation for practical usage of femtosecond laser plasmonic lithography,with the prospect of expansion to other two-dimensional materials for novel device applications. | Tingting Zou Bo Zhao Wei Xin Ye Wang Bin Wang Xin Zheng Hongbo Xie Zhiyu Zhang Jianjun Yang Chunlei Guo | 2020 | Light(Science & Applications)2020,9,1: | 17 |
| 11 | Chronology,Hf isotopes,geochemistry,and petrogenesis of the magmatic rocks in the Shizishan ore field of Tongling,Anhui Province显示文摘LA-ICPMS zircon U-Pb dating of intrusive rocks from the Shizishan ore field,Tongling,Anhui Province shows that the crystallization ages of Baimangshan pyroxene diorite,Shizishan and Dongguashan quartz diorite are 139±1.9,138.0±1.7,and 138.4±1.7 Ma,respectively.These three intrusions are high-potassium,alkali-rich,meta-aluminous,and are characterized by enrichment of light rare earth elements and large-ion lithophile elements,depletion of heavy rare-earth elements(HREE) and high field strength elements,and slightly negative Eu anomalies.In-situ Hf analysis of zircon for these three intrusions shows large ranges of Hf isotope compositions:the ε Hf(t) values are ε Hf(t)= 3.3 to 14.4 for Baimangshan,14.1 to 23.9 Dongguashan,and 14.7 to 26.9 for Shizishan.The ε Hf(t) values of both the Dongguashan and Shizishan quartz diorites are significantly lower than those of Baimangshan pyroxene diorite.Elemental geochemistry and in-situ zircon Hf isotope analyses indicate that the three intrusions were formed through mixing of granitic magma formed by partial melting of the lower crust and water-rich basic magma derived from the enriched lithospheric mantle.The Dongguashan and Shizishan quartz diorites involved greater crustal components than Baimangshan pyroxene diorite.The Dongguashan and Shizishan quartz diorites have geochemical features similar to the adakite,such as high Sr,low Y,and high Sr/Y ratios.Such geochemical features can be attributed to some fractional crystallization of apatite and sphene,and insignificant plagioclase fractional crystallization after magma mixing.These three intrusions are the products of complex crust-mantle interaction during the regional tectonic regime transition from compression to extension. | GUO WeiMin LU JianJun JIANG ShaoYong ZHANG RongQing ZHAO ZhanJie | 2013 | Science China Earth Sciences2013,56,6: | 15 |
| 12 | Spatial dynamics of aboveground carbon stock in urban green space:a case study of Xi'an,China显示文摘Greenhouse gas emission of carbon dioxide(CO2) is one of the major factors causing global climate change.Urban green space plays a key role in regulating the global carbon cycle and reducing atmospheric CO2.Quantifying the carbon stock,distribution and change of urban green space is vital to understanding the role of urban green space in the urban environment.Remote sensing is a valuable and effective tool for monitoring and estimating aboveground carbon(AGC) stock in large areas.In the present study,different remotely-sensed vegetation indices(VIs) were used to develop a regression equation between VI and AGC stock of urban green space,and the best fit model was then used to estimate the AGC stock of urban green space within the beltways of Xi'an city for the years 2004 and 2010.A map of changes in the spatial distribution patterns of AGC stock was plotted and the possible causes of these changes were analyzed.Results showed that Normalized Difference Vegetation Index(NDVI) correlated moderately well with AGC stock in urban green space.The Difference Vegetation Index(DVI),Ratio Vegetation Index(RVI),Soil Adjusted Vegetation Index(SAVI),Modified Soil Adjusted Vegetation Index(MSAVI) and Renormalized Difference Vegetative Index(RDVI) were lower correlation coefficients than NDVI.The AGC stock in the urban green space of Xi'an in 2004 and 2010 was 73,843 and 126,621 t,respectively,with an average annual growth of 8,796 t and an average annual growth rate of 11.9%.The carbon densities in 2004 and 2010 were 1.62 and 2.77 t/hm2,respectively.Precipitation was not an important factor to influence the changes of AGC stock in the urban green space of Xi'an.Policy orientation,major ecological greening projects such as 'transplanting big trees into the city' and the World Horticultural Exposition were found to have an important impact on changes in the spatiotemporal patterns of AGC stock. | ZhengYang YAO JianJun LIU XiaoWen ZHAO DongFeng LONG Li WANG | 2015 | Journal of Arid Land2015,7,3: | 13 |

| 15 | Coupling Rice with Fish for Sustainable Yields and Soil Fertility in China显示文摘About 30 million hectares of rice are cultivated annually in China(FAOSTAT,2019).Because most rice fields are wellirrigated and suitable for fish living(‘fish’here refers to various aquatic animals like carps,prawns,crabs,soft shell turtles,etc.)(Fernando,1993),many efforts have been made to determine how well rice farming and aquaculture can be coupled as a rice-fish system(RFS),of which the same land and water produces both rice and aquatic products.With the technological guidance of RFSs and political supports from the Ministry of Agriculture and Rural Affairs of China since 2010(Supplemental Table 1),multiple types of large-scale,high-efficiency and technologically intensive RFSs are now being demonstrated in the main rice-growing areas of China(National Fisheries Technology Extension Centre,2019),and in total about 1.2 million hectares of rice fields are under RFSs. | GUO Liang HU Liangliang ZHAO Lufeng SHI Xiaoyu JI Zijun DING Lilian REN Weizheng ZHANG Jian TANG Jianjun CHEN Xin | 2020 | Rice science2020,27,3: | 11 |
| 16 | Petrogenetic differences between the Middle-Late Jurassic Cu-Pb-Zn-bearing and W-bearing granites in the Nanling Range,South China: A case study of the Tongshanling and Weijia deposits in southern Hunan Province显示文摘The Middle-Late Jurassic Cu-Pb-Zn-bearing and W-bearing granites in the Nanling Range have distinctly different mineralogical and geochemical signatures. The Cu-Pb-Zn-bearing granites are dominated by metaluminous amphibole-bearing granodiorites, which have higher CaO/(Na2O+K2O) ratios, light/heavy rare earth element(LREE/HREE) ratios, and δEu values,lower Rb/Sr ratios, and weak Ba, Sr, P, and Ti depletions, exhibiting low degrees of fractionation. The W-bearing granites are highly differentiated and peraluminous, and they have lower CaO/(Na2O+K2O) ratios, LREE/HREE ratios, and δEu values,higher Rb/Sr ratios, and strong Ba, Sr, P, and Ti depletions. The Cu-Pb-Zn-bearing granites were formed predominantly between155.2 and 167.0 Ma with a peak value of 160.6 Ma, whereas the W-bearing granites were formed mainly from 151.1 to 161.8Ma with a peak value of 155.5 Ma. There is a time gap of about 5 Ma between the two different types of ore-bearing granites.Based on detailed geochronological and geochemical studies of both the Tongshanling Cu-Pb-Zn-bearing and Weijia W-bearing granites in southern Hunan Province and combined with the other Middle-Late Jurassic Cu-Pb-Zn-bearing and W-bearing granites in the Nanling Range, a genetic model of the two different types of ore-bearing granites has been proposed. Asthenosphere upwelling and basaltic magma underplating were induced by the subduction of the palaeo-Pacific plate. The underplated basaltic magmas provided heat to cause a partial melting of the mafic amphibolitic basement in the lower crust, resulting in the formation of Cu-Pb-Zn mineralization related granodioritic magmas. With the development of basaltic magma underplating,the muscovite-rich metasedimentary basement in the upper-middle crust was partially melted to generate W-bearing granitic magmas. The compositional difference of granite sources accounted for the metallogenic specialization, and the non-simultaneous partial melting of one source followed by the other brought about a time gap of about 5 Ma between the Cu-Pb-Zn-bearing and W-bearing granites. | HUANG XuDong LU JianJun Stanislas SIZARET WANG RuCheng MA DongSheng ZHANG RongQing ZHAO Xu WU JinWei | 2017 | Science China Earth Sciences2017,60,7: | 9 |

| 18 | Mechanisms underlying attenuation of apoptosis of cortical neurons in the hypoxic brain by flavonoids from the stems and leaves of Scutellaria baicalensis Georgi显示文摘Flavonoids from the stems and leaves of Scutellaria baicalensis Georgi, an antioxidant, markedly improve memory impairments and neuronal injuries. In the present study, primary cortical neurons of rats were exposed to potassium cyanide to establish a model of in vitro neural cell apoptosis. Inhibition of apoptosis by flavonoids from the stems and leaves of Scutellaria baicalensis Georgi at concentrations of 18.98, 37.36, and 75.92 μg/mL was detected using this model. These flavonoids dramatically increased cell survival, inhibited cell apoptosis and excessive production of malondialdehyde, and increased the activities of superoxide dismutase, glutathione peroxidase, and Na+-K+-ATPase in primary cortical neurons exposed to potassium cyanide. The flavonoids from the stems and leaves of Scutellaria baicalensis Georgi were originally found to have a polyhydric structure and to protect against cerebral hypoxia in in vitro and in vivo models, including hypoxia induced by potassium cyanide or cerebral ischemia. The present study suggests that flavonoids from the stems and leaves of Scutellaria baicalensis Georgi exert neuroprotective effects via modulation of oxidative stress, such as malondialdehyde, superoxide dismutase, glutathione peroxidase and Na+-K+-ATPase disorders induced by potassium cyanide. | Guangxin Miao Hongxiang Zhao Ke Guo Jianjun Cheng Shufeng Zhang Xiaofeng Zhang Zhenling Cai Hong Miao Yazhen Shang | 2014 | Neural Regeneration Research2014,9,17: | 8 |
| 19 | Regional eco-efficiency evaluation and spatial pattern analysis of the Yangtze River Economic Zone显示文摘The environmental ecology of the Yangtze River Economic Zone(YREZ)faces ecological function decline,deterioration and degradation under intense human activities,long-term development and utilization and its economy has developed rapidly over recent decades.Eco-efficiency is considered as a measure of coordinated development of economy,resources,environment and ecology,and is currently considered a very important issue.In this paper,based on the slack-based measure and data envelope analysis model,we take 129 prefecture-level cities of the YREZ as the study unit and measure the eco-efficiency of the YREZ in 2000,2005,2010 and 2015,which considers undesired output.The evaluation of the status quo of the regional eco-efficiency development was carried out at provincial,prefectural and city scales.The spatial autocorrelation test model and standard deviation ellipse were used to analyze the spatially distributed characteristics and the evolutionary regularity of eco-efficiency.Our study suggested that the eco-efficiency value varied significantly at different spatiotemporal scales and the overall distribution presented an'N-shaped'pattern,the value is the largest downstream and the smallest upstream.Regional eco-efficiency presented certain volatility in growth and a clear spatial positive agglomeration trend from 2000 to 2015.The spatial distribution of each agglomeration area was also significantly different,forming some high-high agglomeration areas at the center of the shaft with Shanghai and surrounding cities,and some low-low agglomeration areas at the center with middle reaches and upstream cities.The low-high over-aggregation and high-low polarization clusters were fewer.At the same time,with the change of the research period,the degree of positive agglomeration became increasingly pronounced and the eco-efficiency gap of the neighborhoodunit reduced.The regional eco-efficiency value of the YREZ presented a spatial distribution pattern in the northeast-southwest axis and the evolutionary pattern of the regional eco-efficiency similarly showed a northeast-southwest orientation. | HA Lin TU Jianjun YANG Jianping XU Chunhai PANG Jiaxing LU Debin YAO Zuolin ZHAO Wenyu | 2020 | Journal of Geographical Sciences2020,30,7: | 8 |
| 20 | Adsorption-energy-based activity descriptors for electrocatalysts in energy storage applications显示文摘Energy storage technologies, such as fuel cells, ammonia production and lithium–air batteries, are important strategies for addressing the global challenge of energy crisis and environmental pollution.Taking overpotential as a direct criterion, we illustrate in theory and experiment that the adsorption energies of charged species such as Li^++e^-and H^++e^-are a central parameter to describe catalytic activities related to electricity-in/electricity-out efficiencies. The essence of catalytic activity is revealed to relate with electronic coupling between catalysts and charged species. Based on adsorption energy, some activity descriptors such as d-band center, e_g-electron number and charge-transfer capacity are further defined by electronic properties of catalysts that directly affect interaction between catalysts and charged species. The present review is helpful for understanding the catalytic mechanisms of these electrocatalytic reactions and developing accurate catalytic descriptors, which can be employed to screen high-activity catalysts in future high-throughput calculations and experiments. | Youwei Wang Wujie Qiu Erhong Song Feng Gu Zhihui Zheng Xiaolin Zhao Yingqin Zhao Jianjun Liu Wenqing Zhang | 2018 | National Science Review2018,5,3: | 8 |
