| 1 | Emission Characteristics of VOCs from Automobile Coating Industry in Chongqing City显示文摘To fully analyze emission characteristics of volatile organic compounds( VOCs) from automobile coating industry in Chongqing City,related enterprises in the city were investigated in detail. The results show that the emission of VOCs from the automobile industry in Chongqing City was approximately 20 000 t in 2012,and the contribution rate of automobile coating was 83%. Most VOCs discharged from automobile coating industry were mainly from the use of coatings,diluents,curing agents and other materials containing VOCs. During the process of automobile coating,VOCs were mainly produced during the processes of spraying and drying. Besides,VOCs are partly produced during the processes of mixing paint,gluing,waxing,and repairing. The major ingredients of VOCs discharged during the process of automobile coating were methylbenzene,dimethylbenzene,trimethylbenzene,cumene,ethyl acetate,butyl alcohol,n-butyl alcohol,isobutyl alcohol,formaldehyde,butanone,acetone,cyclohexanone,and methyl ethyl ketone. Besides,the ingredients of naphtha and aromatic hydrocarbon in VOCs need to be determined. The maximum ozone formation potential( OFP) of the above pollutants by the typical enterprises was 900-1 300 mg/m^3. The production of secondary organic aerosol( SOA) was 3 636-11 073 t/a,which didn't include the contribution of aldehydes,ketones,ethers and esters to SOA. This research could provide scientific reference for the establishment of emission standard,control technology and management methods of VOCs from automobile coating industry that accord with economic and social development in Chongqing City. | Zhou Zhi'en Fang Weikai Luo Qian Wang Xiaochen Wu Liping | 2017 | Meteorological and Environmental Research2017，8，3： | 3 |
| 2 | Discussion about Environmental Impact Assessment of Shale Gas Development显示文摘China is the third country to develop and utilize shale gas after the United States and Canada. However,shale gas development has significant environmental problems,such as huge consumption of both land and water resources,water pollution risk of hydraulic fracturing,leakage risk of shale gas and so on. At present,environmental impact assessment of shale gas development in China has been conducted based on the Technical Guideline for Environmental Impact Assessment——Constructional Project of Petroleum and Natural Gas Development on Land which lacks clear guidance on selection and quantitative analysis of pollution factors. In this paper,based on the experience of shale gas development in America,special environmental problems that need to be noticed for shale gas development were summarized,and the supplement to the technical guideline for environmental impact assessment of shale gas development was discussed to improve the environmental impact assessment system. | Zhou Zhi en Fang Weikai Song Dan Chen Min Luo Qian Wang Xiaochen | 2016 | Meteorological and Environmental Research2016，7，5： | 1 |
| 3 | Impacts of reducing air pollutants and CO_(2) emissions in urban road transport through 2035 in Chongqing, China显示文摘The road transport sector in megacities is confronted with pressing local air pollution and carbon dioxide(CO_(2))control issues.To determine effective policy instruments for saving energy and the co-control of air pollutants and CO_(2),several mainstream measures were examined and compared in Chongqing's road transport sector from 2017 to 2035.An integration assessment framework was developed by combining the Long-range Energy Alternatives Planning(LEAP)system and a set of quantitative methods for evaluating the co-benefits of emission reductions(including the air pollutant equivalent(APeq),cocontrol coordinate system,and pollutant reduction cross-elasticity(Elsa/b)).Results showed that the shifting transportation modes scenario presented the most significant potential for energy-saving and emission reductions,reducing energy use by 30.9%and air pollutants and CO_(2) emissions by approximately 27e32%compared with the business as usual(BAU)scenario in 2035.The improving energy efficiency scenario also provided significant co-benefits for reducing air pollutants and CO_(2) emissions.Nevertheless,the promoting alternative fuel scenario may increase fine particulate matter(PM2.5)emissions by 2.2%compared to BAU in 2035 under the cleanness of regional electricity in 2017.Our findings suggest that the shifting transportation modes were effective measures to reduce air pollutants and CO_(2) in the short term synergistically,and highlighted the importance of cleaner electricity generation to develop electric vehicles in the medium and long term. | Linfeng Duan Wei Hu Di Deng Weikai Fang Min Xiong Peili Lu Zhenliang Li Chongzhi Zhai | 2021 | Environmental Science and Ecotechnology2021，，4： | 0 |
| 4 | Radial velocity measurements from LAMOST medium-resolution spectroscopic observations: a pointing towards the Kepler field显示文摘Radial velocity is one of the key measurements in understanding the fundamental properties of stars, stellar clusters and the Galaxy. A plate of stars in the Kepler field was observed in May of 2018 with the medium-resolution spectrographs of LAMOST, aiming to test the performance of this new system which is the upgraded equipment of LAMOST after the first five-year regular survey. We present our analysis on the radial velocity measurements(RVs) derived from these data. The results show that slight and significant systematic errors exist among the RVs obtained from the spectra collected by different spectrographs and exposures, respectively. After correcting the systematic errors with different techniques, the precision of RVs reaches ~1.3,~1.0,~0.5 and ~0.3 km s^(-1) at S/Nr = 10, 20, 50 and 100, respectively. Comparing with the RVs of standard stars from the APOGEE survey, our RVs are calibrated with a zero-point shift of~7 km s^(-1). The results indicate that the LAMOST medium-resolution spectroscopic system may provide RVs with a reasonable accuracy and precision for the selected targets. | Nian Liu Jian-Ning Fu Weikai Zong Jian-Rong Shi A-Li Luo Hao-Tong Zhang Xiang-Qun Cui Yong-Hui Hou Yang Pan Xin-Rui Shan Jian-Jun Chen Zhong-Rui Bai Jian-Xing Chen Bing Du Wen Hou Yu-Chen Liu Hao Tian Jiang-Tao Wang Jia-Xin Wang Ke-Fei Wu Yu-Zhong Wu Hong-Liang Yan Fang Zuo | 2019 | Research in Astronomy and Astrophysics2019，19，5： | 0 |
