| 1 | ECharts: A declarative framework for rapid construction of web-based visualization显示文摘While there have been a dozen of authoring systems and programming toolkits for visual design and development,users who do not have programming skills,such as data analysts or interface designers,still may feel cumbersome to efficiently implement a web-based visualization.In this paper,we present ECharts,an open-sourced,web-based,cross-platform framework that supports the rapid construction of interactive visualization.The motivation is driven by three goals:easy-touse,rich built-in interactions,and high performance.The kernel of ECharts is a suite of declarative visual design language that customizes built-in chart types.The underlying streaming architecture,together with a high-performance graphics renderer based on HTML5 canvas,enables the high expandability and performance of ECharts.We report the design,implementation,and applications of ECharts with a diverse variety of examples.We compare the utility and performance of ECharts with C3.js,HighCharts,and Chart.js.Results of the experiments demonstrate the efficiency and scalability of our framework.Since the first release in June 2013,ECharts has iterated 63 versions,and attracted over 22,000 star counts and over 1700 related projects in the GitHub.ECharts is regarded as a leading visualization development tool in the world,and ranks the third in the GitHub visualization tab. | Deqing Li Honghui Mei Yi Shen Shuang Su Wenli Zhang Junting Wang Ming Zu Wei Chen | 2018 | Visual Informatics2018，2，2： | 69 |
| 2 | The impact of meteorological changes from 2013 to 2017 on PM2.5 mass reduction in key regions in China显示文摘In 2013,China issued the'Action Plan for the Prevention and Control of Air Pollution'('Ten Statements of Atmosphere')and implemented a series of pollution reduction measures from 2013 to 2017.In key regions of China,the mass concentrations of particulate matter with aerodynamic equivalent diameters less than 2.5μm(PM2.5)have dropped significantly.However,the contributions of meteorological changes to PM2.5 reduction are largely uncertain,which has attracted particular concern from the government and the public.Here,we investigated the impact of large-scale and boundary layer(BL)meteorological conditions on aerosol pollution and estimated the contributions of meteorological changes to PM2.5 reduction based on in-depth analysis and diagnosis of various observed meteorological elements and an integrated pollution-linked meteorological index(PLAM,which is approximately and linearly related to PM mass concentration).In this study,we found that the meteorological conditions worsened in 2014 and 2015 and improved in 2016 and 2017 relative to those in 2013 in key regions in China.In 2017 relative to 2013,only^5%(approximately 13%of the total PM2.5 decline)of the 39.6%reduction in PM2.5 mass concentrations can be attributed to meteorological changes in the Beijing-Tianjin-Hebei(BTH)region,and only^7%(approximately 20%of the total PM2.5 decline)of the 34.3%reduction can be attributable to meteorological changes in the Yangtze River Delta(YRD)region.Overall,the PM2.5 reduction due to meteorological improvement is much lower than the observed PM2.5 reduction in these areas,which indicates that emission reduction during the five-year implementation of the'Ten Statements of Atmosphere'is the dominant factor in the improvement in air quality.The changes in meteorology and climate are conducive to PM2.5 reduction but do not dominate the substantial improvement in air quality.Similar to the above regions,in the Pearl River Delta(PRD)region,the impact of meteorological changes on the annual averaged PM2.5 concentration from 2013 to2017 was relatively weak,and the PM2.5 reduction was mainly due to emission reductions.During winter 2017(January,February,and December of this year),the meteorological conditions improved-20%in the BTH region(observed total PM2.5reduction:40.2%)and-30%in the YRD region(observed total PM2.5 reduction:38.2%)relative to those in 2013,showing the meteorological factors played more important role in the decrease of PM2.5 in winter of these years in the two regions,respectively.The meteorological conditions in winter 2016 were 14%better than those in winter 2017,but the PM2.5 reduction in winter 2016 was still less than that in winter 2017,reinforcing the significant contributions of the increasing efforts to reduce PM2.5 emissions in 2017.The substantial progress of strict emission measures was also confirmed by a comparison of several persistent heavy aerosol pollution episodes(HPEs)with similar meteorological conditions.It is found that the decrease of PM2.5mass caused by emission reduction increases year by year,especially the decrease of PM2.5 concentration in 2016 and 2017.In China,HPEs mainly occur in winter,when meteorological conditions are approximately 40-100%worse than in other seasons.This worsening is partly due to the harbor effect of high topography,including downdrafts and the weak wind zone,and partly due to the increasingly stable regional BL structure caused by climate warming.For the formation of HPEs,it occurred under regional stagnant and stable conditions associated with upper-level circulation patterns,including the zonal westerly winds type and high-pressure ridges.After pollution formation,PM2.5 with mass accumulated to a certain degree can further worsen the BL meteorological conditions.The feedback effect associated with worsening conditions dominates PM2.5 mass explosive growth.In the context of high air pollutant emissions in China,unfavorable meteorological conditions are the necessary external conditions for the formation and accumulation of HPEs.Therefore,reducing aerosol pollution significantly during the earlier transport stage is critical in reducing persistent HPEs.Currently,even under favorable meteorological conditions,allowing emissions without restriction is also not advisable because aerosol pollution allowed to accumulate to a certain extent will significantly worsen the BL meteorological conditions and close the'meteorological channels'available for pollution dispersion. | Xiaoye ZHANG Xiangde XU Yihui DING Yanju LIU Hengde ZHANG Yaqiang WANG Junting ZHONG | 2019 | Science China Earth Sciences2019，62，12： | 42 |
| 3 | Relative Contributions of Boundary-Layer Meteorological Factors to the Explosive Growth of PM2.5 during the Red-Alert Heavy Pollution Episodes in Beijing in December 2016显示文摘Based on observations of urban mass concentration of fine particulate matter smaller than 2.5 μm in diameter(PM_(2.5)), ground meteorological data, vertical measurements of winds, temperature, and relative humidity(RH), and ECMWF reanalysis data, the major changes in the vertical structures of meteorological factors in the boundary layer(BL) during the heavy aerosol pollution episodes(HPEs) that occurred in winter 2016 in the urban Beijing area were analyzed. The HPEs are divided into two stages: the transport of pollutants under prevailing southerly winds, known as the transport stage(TS), and the PM_(2.5) explosive growth and pollution accumulation period characterized by a temperature inversion with low winds and high RH in the lower BL, known as the cumulative stage(CS). During the TS, a surface high lies south of Beijing, and pollutants are transported northwards. During the CS, a stable BL forms and is characterized by weak winds, temperature inversion, and moisture accumulation. Stable atmospheric stratification featured with light/calm winds and accumulated moisture(RH > 80%) below 250 m at the beginning of the CS is closely associated with the inversion, which is strengthened by the considerable decrease in near-surface air temperature due to the interaction between aerosols and radiation after the aerosol pollution occurs. A significant increase in the PLAM(Parameter Linking Aerosol Pollution and Meteorological Elements) index is found, which is linearly related to PM mass change. During the first 10 h of the CS, the more stable BL contributes approximately 84% of the explosive growth of PM_(2.5) mass. Additional accumulated near-surface moisture caused by the ground temperature decrease, weak turbulent diffusion, low BL height, and inhibited vertical mixing of water vapor is conducive to the secondary aerosol formation through chemical reactions, including liquid phase and heterogeneous reactions, which further increases the PM_(2.5) concentration levels. The contribution of these reaction mechanisms to the explosive growth of PM_(2.5) mass during the early CS and subsequent pollution accumulation requires further investigation. | junting zhong xiaoye zhang yaqiang wang junying sun yangmei zhang jizhi wang kaiyan tan xiaojing shen haochi che lu zhang zhouxiang zhang xuefei qi huarong zhao sanxue ren yang li | 2017 | Journal of Meteorological Research2017，31，5： | 25 |
| 4 | Aerosol Hygroscopicity during the Haze Red-Alert Period in December 2016 at a Rural Site of the North China Plain显示文摘A humidification system was deployed to measure aerosol hygroscopicity at a rural site of the North China Plain during the haze red-alert period 17–22 December 2016. The aerosol scattering coefficients under dry [relative humidity(RH) < 30%] and wet(RH in the range of 40%–85%) conditions were simultaneously measured at wavelengths of450, 550, and 700 nm. It is found that the aerosol scattering coefficient and backscattering coefficient increased by only 29% and 10%, respectively when RH went up from 40% to 80%, while the hemispheric backscatter fraction went down by 14%, implying that the aerosol hygroscopicity represented by the aerosol scattering enhancement factor f(RH) is relatively low and RH exerted little effects on the aerosol light scattering in this case. The scattering enhancement factors do not show significant differences at the three wavelengths, only with an approximate 2% variation, suggesting that the aerosol hygroscopicity is independent of the wavelength. Aerosol hygroscopicity is highly dependent on the aerosol chemical composition. When there is a large mass fraction of inorganics and a small mass fraction of organic matter, f(RH) reaches a high value. The fraction of NO_3^- was strongly correlated with the aerosol scattering coefficient at RH = 80%, which suggests that NO_3^- played an important role in aerosol hygroscopic growth during the heavy pollution period. | Xuefei QI Junying SUN Lu ZHANG Xiaojing SHEN Xiaoye ZHANG Yangmei ZHANG Yaqiang WANG Haochi CHE Zhouxiang ZHANG Junting ZHONG Kaiyan TAN Huarong ZHAO Sanxue REN | 2018 | Journal of Meteorological Research2018，32，1： | 7 |
| 5 | Traditional Chinese Medicine syndrome-related herbal prescriptions in treatment of malignant tumors显示文摘OBJECTIVE: To investigate the distribution characteristics of TCM syndromes and the related herbal prescriptions for malignant tumors (MT). METHODS: A clinical database of the TCM syndromes and the herbal prescriptions in treatment of 136 MT patients were established. The data were then analyzed using cluster and frequency analysis. RESULTS: According to the cluster analysis, the TCM syndromes in MT patients mainly included two patterns: deficiency of both Qi and Yin and internal accumulation of toxic heat. The commonly-prescribed herbs were Huangqi (Astraglus), Nüzhen-zi (Fructus Ligustri Lucidi), Lingzhi (Ganoderma Lucidum), Huaishan (Dioscorea Opposita), Xiakucao (Prunella Vulgaris), and Baihuasheshecao (Herba Hedyotidis). CONCLUSION: Deficiency of Qi and Yin is the primary syndrome of MT, and internal accumulation of toxic heat is the secondary syndrome. The herbs for Qi supplementation and Yin nourishment are mainly used, with the assistance of herbs for heat-clearance and detoxification. | Zhizhen Liu Songyi Chen Jing Cai Enda Zhang Lan Lan Junting Zheng Lianming Liao Xuemei Yang Changen Zhou Jian Du | 2013 | Journal of Traditional Chinese Medicine2013，33，1： | 7 |
| 6 | Diffuse Intrinsic Pontine Gliomas Exhibit Cell Biological and Molecular Signatures of Fetal Hindbrain-Derived Neural Progenitor Cells显示文摘Diffuse intrinsic pontine glioma(DIPG) is the main cause of brain tumor-related death among children.Until now, there is still a lack of effective therapy with prolonged overall survival for this disease. A typical strategy for preclinical cancer research is to find out the molecular differences between tumor tissue and para-tumor normal tissue, in order to identify potential therapeutic targets. Unfortunately, it is impossible to obtain normal tissue for DIPG because of the vital functions of the pons.Here we report the human fetal hindbrain-derived neural progenitor cells(pontine progenitor cells, PPCs) as normal control cells for DIPG. The PPCs not only harbored similar cell biological and molecular signatures as DIPG glioma stem cells, but also had the potential to be immortalized by the DIPG-specific mutation H3 K27 M in vitro. These findings provide researchers with a candidate normal control and a potential medicine carrier for preclinical research on DIPG. | Yu Sun Cheng Xu Changcun Pan Xin Chen Yibo Geng Yuliang Wu Peng Zhang Wenhao Wu Yu Wang Deling Li Zhen Wu Junting Zhang Qiaoran Xi Liwei Zhang | 2019 | Neuroscience Bulletin2019，35，2： | 2 |
| 7 | Nonlinear optical absorption properties of InP nanowires and applications as a saturable absorber显示文摘Indium phosphide(InP)nanowires(NWs)have attracted significant attention due to their exotic properties that are different from the bulk counterparts,and have been widely used for light generation,amplification,detection,modulation,and switching,etc.Here,high-quality InP NWs were directly grown on a quartz substrate by the Au-nanoparticle assisted vapor-liquid-solid method.We thoroughly studied their nonlinear optical absorption properties at 1.06μm by the open-aperture Z-scan method.Interestingly,a transition phenomenon from satu-rable absorption(SA)to reverse saturable absorption(RSA)was observed with the increase of the incident laser intensity.In the analysis,we found that the effective nonlinear absorption cofficient(βeff-10^2 cm/MW)under the SA process was 3 orders of magnitude larger than that during the RSA processes.Furthermore,the SA proper-ties of InP NWs were experimentally verified by using them as a saturable absorber for a passively Q-switched Nd:YVO4 solid-state laser at 1.06μm,where the shortest pulse width of 462 ns and largest single pulse energy of 1.32μJ were obtained.Moreover,the ultrafast carrier relaxation dynamics were basically studied,and the intraband and inter-band ultrafast carrier relaxation times of 8.1 and 63.8 ps,respectively,were measured by a degenerate pump-probe method with the probe laser of 800 nm.These results well demonstrate the nonlinear optical absorption properties,which show the excellent light manipulating capabilities of InP NWs and pave a way for their applications in ultrafast nanophotonic devices. | JUNTING LIU HONGKUN NIE BINGZHENG YAN KEJIAN YANG HE YANG VLADISLAV KHAYRUDINOV HARRI LIPSANEN BAITAO ZHANG JINGLIANG HE | 2020 | Photonics Research2020，8，6： | 2 |
| 8 | Robust prediction of hourly PM_(2.5) from meteorological data using LightGBM显示文摘Retrieving historical fine particulate matter(PM_(2.5))data is key for evaluating the long-term impacts of PM_(2.5) on the environment,human health and climate change.Satellite-based aerosol optical depth has been used to estimate PM_(2.5),but estimations have largely been undermined by massive missing values,low sampling frequency and weak predictive capability.Here,using a novel feature engineering approach to incorporate spatial effects from meteorological data,we developed a robust Light GBM model that predicts PM_(2.5) at an unprecedented predictive capacity on hourly(R^(2)=0.75),daily(R^(2)=0.84),monthly(R^(2)=0.88)and annual(R^(2)=0.87)timescales.By taking advantage of spatial features,our model can also construct hourly gridded networks of PM_(2.5).This capability would be further enhanced if meteorological observations from regional stations were incorporated.Our results show that this model has great potential in reconstructing historical PM_(2.5) datasets and real-time gridded networks at high spatial-temporal resolutions.The resulting datasets can be assimilated into models to produce long-term re-analysis that incorporates interactions between aerosols and physical processes. | Junting Zhong Xiaoye Zhang Ke Gui Yaqiang Wang Huizheng Che Xiaojing Shen Lei Zhang Yangmei Zhang Junying Sun Wenjie Zhang | 2021 | National Science Review2021，8，10： | 2 |
| 9 | Comparison of Submicron Particles at a Rural and an Urban Site in the North China Plain during the December 2016 Heavy Pollution Episodes显示文摘An extensive field experiment for measurement of physical and chemical properties of aerosols was conducted at an urban site in the Chinese Academy of Meteorological Sciences(CAMS) in Beijing and at a rural site in Gucheng(GC), Hebei Province in December 2016. This paper compares the number size distribution of submicron particle matter(PM1, diameter < 1 μm) between the two sites. The results show that the mean PM1 number concentration at GC was twice that at CAMS, and the mass concentration was three times the amount at CAMS. It is found that the accumulation mode(100–850 nm) particles constituted the largest fraction of PM1 at GC, which was significantly correlated with the local coal combustion, as confirmed by a significant relationship between the accumulation mode and the absorption coefficient of soot particles. The high PM1 concentration at GC prevented the occurrence of new particle formation(NPF) events, while eight such events were observed at CAMS. During the NPF events, the mass fraction of sulfate increased significantly, indicating that sulfate played an important role in NPF. The contribution of regional transport to PM1 mass concentration was approximately 50% at both sites, same as that of the local emission. However, during the red-alert period when emission control took place, the contribution of regional transport was notably higher. | Xiaojing SHEN Junying SUN Xiaoye ZHANG Yangmei ZHANG Yaqiang WANG Kaiyan TAN Peng WANG Lu ZHANG Xuefei QI Haochi CHE Zhouxiang ZHANG Junting ZHONG Huarong ZHAO Sanxue REN | 2018 | Journal of Meteorological Research2018，32，1： | 2 |

| 11 | Atmospheric Particle Hygroscopicity and the Influence by Oxidation State of Organic Aerosols in Urban Beijing显示文摘A hygroscopic tandem differentialmobility analyser(H-TDMA)was used to observe the sizeresolved hygroscopic characteristics of submicron particles in January and April 2018 in urban Beijing.The probability distribution of the hygroscopic growth factor(HGF-PDF)in winter and spring usually showed a bimodal pattern,with more hygroscopic mode(MH)being more dominant.The seasonal variation in particle hygroscopicity was related to the origin of air mass,which received polluted southerly air masses in spring and clean northwesterly air masses in winter.Particles showed stronger hygroscopic behaviour during heavy pollution episodes(HPEs)with elevated concentrations of secondary aerosols,especially higher mass fraction of nitrate,which were indicated using the PM2.5(particulate matter with diameter below 2.5μm)mass concentration normalised by CO mass concentration.The hygroscopic parameter(κ)values were calculated using H-TDMA(κhtdma)and chemical composition(κchem).The closure study showed thatκchem was overestimated in winter afternoon when compared withκhtdma,because the organic particle hygroscopic parameter(κorg)was overestimated in the calculations.It was influenced by the presence of a high concentration of hydrocarbon-like organic aerosol(HOA)with a weak water uptake ability.A positive relationship was observed betweenκorg and the ratio of oxygenated organic aerosol(OOA)and HOA,thereby indicating that the strong oxidation state enhanced the hygroscopicity of the particles.This study revealed the effect of local emission sources and secondary aerosol formation processes on particle hygroscopicity,which is of great significance for understanding the pollution formation mechanism in the North China Plain. | Sinan Zhang Xiaojing Shen Junying Sun Yangmei Zhang Xiaoye Zhang Can Xia Xinyao Hu Junting Zhong Jialing Wang Shuo Liu | 2023 | Journal of Environmental Sciences2023，，2： | 1 |

| 14 | Synthesis and Enhanced Superplasticity of the Zirconia-dispersed Alumina Nanocomposite显示文摘A series of alumina-zirconia composites with various grain sizes were prepared from the nano-sized powders with different agglomerations. Microstructural analysis of the sintered compacts indicates that the as-sintered material is a typical intra/inter granular nanocomposite with uniform distribution of the zirconia grains in the alumina matrix.Superplastic deep drawing test under different conditions demonstrates that dense Al2O3/ZrO2 samples with average grain size of 230 nm can be elongated to a dome height of at least 12 mm at the punch rate of 0.6 mm.min-1at 1400℃. Further drawing tests show that for the composites with larger grain size, such elongation cannot be achieved at such a strain rate. | Guoqing CHEN, Kaifeng ZHANG, Wenbo HAN and Junting LUOSchool of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, ChinaProf., Ph.D., | 2005 | Journal of Materials Science & Technology2005，21，1： | 1 |
