| 3 | Experimental study on the laminar flame speed of hydrogen/natural gas/air mixtures显示文摘Laminar flame speeds of hydrogen/natural gas/air mixtures have been measured over a full range of fuel compositions(0-100%volumetric fraction of H_(2))and a wide range of equivalence ratio using Bunsen burner.High sensitivity scientific CCD camera is use to capture the image of laminar flame.The reaction zone area is employed to calculate the laminar flame speed.The initial temperature and pressure of fuel air mixtures are 293 K and 1 atm.The laminar flame speeds of hydrogen/air mixture and natural gas/air mixture reach their maximum values 2.933 and 0.374 m/s when equivalence ratios equal to 1.7 and 1.1,respectively.The laminar flame speeds of hydrogen/natural gas/air mixtures rise with the increase of volumetric fraction of hydrogen.Moreover,the increase in laminar flame speed as the volumetric fraction of hydrogen increases presents an exponential increasing trend versus volumetric fraction of hydrogen.Empirical formulas to calculate the laminar flame speeds of hydrogen,natural gas,and hydrogen/natural gas mixtures are also given.Using these formulas,the laminar flame speed at different hydrogen fractions and equivalence ratios can be calculated. | Chen DONG Qulan ZHOU Xiaoguang ZHANG Qinxin ZHAO Tongmo XU Shi’en HUI | 2010 | Frontiers of Chemical Science and Engineering2010,4,4: | 4 |
| 4 | 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 |
| 5 | Dust storms in northern China during the last 500 years显示文摘The history and mechanisms of dust storms in northern China remain unclear owing to the paucity of reliable longterm,high-resolution geological records.In this study,we reconstructed the dust storm history of the last~500 years in northern China,based on sedimentary coarse fraction(>63μm)of a well-dated core from Lake Daihai,Inner Mongolia.The highresolution data reveal three intervals of frequent dust storms:AD 1520–1580,AD 1610–1720,and AD 1870–2000.The dust storm events in the Lake Daihai area were broadly synchronous with those inferred from other historical or geological records and generally occurred during cold intervals.Changes in the intensity of Siberian High and the westerlies modulated by temperature variations are the likely major factors controlling dust storm dynamics.An interesting feature is that although the intensities of dust storms have been systematically increased during the recent warming period,a clear decreasing trend within this period is evident.The recent increase in average dust storm intensity may be ascribed to an increase in particle supply resulting from a rapid increase in human activity,whereas the weakening trend was likely caused by decreases in average wind speed resulting from the recent global warming. | Shuang ZHANG Hai XU Jianghu LAN Yonaton GOLDSMITH Adi TORFSTEIN Guilin ZHANG Jin ZHANG Yunping SONG Kang’en ZHOU Liangcheng TAN Sheng XU Xiaomei XU Yehouda ENZEL | 2021 | Science China Earth Sciences2021,64,5: | 3 |

| 9 | Significant loss of soil inorganic carbon at the continental scale显示文摘Widespread soil acidification due to atmospheric acid deposition and agricultural fertilization may greatly accelerate soil carbonate dissolution and CO_(2) release.However,to date,few studies have addressed these processes.Here,we use meta-analysis and nationwide-survey datasets to investigate changes in soil inorganic carbon(SIC)stocks in China.We observe an overall decrease in SIC stocks in topsoil(0-30 cm)(11.33 g C m^(-2)yr^(-1))from the 1980s to the 2010s.Total SIC stocks have decreased by∼8.99±2.24%(1.37±0.37 Pg C).The average SIC losses across China(0.046 Pg C yr^(-1))and in cropland(0.016 Pg C yr^(-1))account for∼17.6%-24.0%of the terrestrial C sink and 57.1%of the soil organic carbon sink in cropland,respectively.Nitrogen deposition and climate change have profound influences on SIC cycling.We estimate that∼19.12%-19.47%of SIC stocks will be further lost by 2100.The consumption of SIC may offset a large portion of global efforts aimed at ecosystem carbon sequestration,which emphasizes the importance of achieving a better understanding of the indirect coupling mechanisms of nitrogen and carbon cycling and of effective countermeasures to minimize SIC loss. | Xiao-Dong Song Fei Yang Hua-Yong Wu Jing Zhang De-Cheng Li Feng Liu Yu-Guo Zhao Jin-Ling Yang Bing Ju Chong-Fa Cai Biao Huang Huai-Yu Long Ying Lu Yue-Yu Sui Qiu-Bing Wang Ke-Ning Wu Feng-Rong Zhang Ming-Kui Zhang Zhou Shi Wan-Zhu Ma Gang Xin Zhi-Ping Qi Qing-Rui Chang En Ci Da-Gang Yuan Yang-Zhu Zhang Jun-Ping Bai Jia-Ying Chen Jie Chen Yin-Jun Chen Yun-Zhong Dong Chun-Lan Han Ling Li Li-Ming Liu Jian-Jun Pan Fu-Peng Song Fu-Jun Sun Deng-Feng Wang Tian-Wei Wang Xiang-Hua Wei Hong-Qi Wu Xia Zhao Qing Zhou Gan-Lin Zhang | 2022 | National Science Review2022,9,2: | 2 |
| 10 | Heat transfer in high density electronics packaging显示文摘In order to get an insight into the thermal characteristic and to evaluate the thermal reliability of the 'System in Packaging'(SIP), a new solution of electronics packaging, a heat transfer model of SIP was developed to predict the heat dissipation capacity and to investigate the effect of different factors on the tempe rature distribution in the electronics. The affecting parameters under consideration include the thermophysical properties of the substrates, the coefficient of convection heat transfer, the thickness of the chip, and the density of power dissipation. ALGOR, a kind of finite element analysis software,was used to do the model simulation. Based on the simulation and analysis of the heat conduction and convection resistance, criteria for the thermal design were established and possible measurement for enhancing power dissipation was provided. The results show that the heat transfer model provides a new and effective way to the thermal design and thermal analysis of SIP and to the mechanical analysis for the further investigation of SIP. | ZHOU Jie min 1, YANG Ying 1, DENG Sheng xiang 1, YI Zheng ming 1, WANG Xi tao 2, CHEN Liu 2, Johan Liu 2 (1.Department of Applied Physics and Heat Engineering, Central South University, Changsha 410083, China 2.Department of Production En | 2001 | Journal of Central South University of Technology2001,8,4: | 2 |

| 12 | Effect of stabilizing elements Nb and Ti on the microstructure and properties of low carbon ferritic stainless steel显示文摘Abstract:The effect of stabilizing elements,such as Nb and Ti,on the microstmcture and properties of low carbon ferritic stainless steel(FSS) has been investigated.The results of the Thermo-calc simulation have shown that the interstitial elements,such as C and N,may be completely stabilized by the addition of Nb and Ti.With the increase of Nb and Ti contents,the a +γtwo phases gradually transfer to a singleα-phase under a high temperature condition,and the content of the carbide M_(23) C_6 gradually decreases.The microstructure has indicated that the combined addition of Nb and Ti can promote the recrystallization of the band structure and form more uniform equiaxed grains.Also,with the increase of Nb and Ti contents,the elongation,the r-value and the corrosion resistance of cold-rolled and annealed sheets are improved prominently.In comparison with the effect of Ti,the addition of Nb is more beneficial to the increase of r-value and the corrosion resistance. | ZHANG Xin SUN Quanshe ZHOU En DU Wei | 2010 | Baosteel Technical Research2010,4,1: | 2 |

| 19 | Extracellular vesicles from hypoxia-preconditioned mesenchymal stem cells alleviates myocardial injury by targeting thioredoxininteracting protein-mediated hypoxia-inducible factor-1αpathway显示文摘BACKGROUND Extracellular vesicles(EVs)derived from hypoxia-preconditioned(HP)mesenchymal stem cells(MSCs)have better cardioprotective effects against myocardial infarction(MI)in the early stage than EVs isolated from normoxic(NC)-MSCs.However,the cardioprotective mechanisms of HP-EVs are not fully understood.AIM To explore the cardioprotective mechanism of EVs derived from HP MSCs.METHODS We evaluated the cardioprotective effects of HP-EVs or NC-EVs from mouse adipose-derived MSCs(ADSCs)following hypoxia in vitro or MI in vivo,in order to improve the survival of cardiomyocytes(CMs)and restore cardiac function.The degree of CM apoptosis in each group was assessed by the terminal deoxynucleotidyl transferase dUTP nick end-labeling and Annexin V/PI assays.MicroRNA(miRNA)sequencing was used to investigate the functional RNA diversity between HP-EVs and NC-EVs from mouse ADSCs.The molecular mechanism of EVs in mediating thioredoxin-interacting protein(TXNIP)was verified by the dual-luciferase reporter assay.Co-immunoprecipitation,western blotting,and immunofluorescence were performed to determine if TXNIP is involved in hypoxia-inducible factor-1 alpha(HIF-1α)ubiquitination and degradation via the chromosomal region maintenance-1(CRM-1)-dependent nuclear transport pathway.RESULTS HP-EVs derived from MSCs reduced both infarct size(necrosis area)and apoptotic degree to a greater extent than NC-EVs from CMs subjected to hypoxia in vitro and mice with MI in vivo.Sequencing of EV-associated miRNAs showed the upregulation of 10 miRNAs predicted to bind TXNIP,an oxidative stress-associated protein.We showed miRNA224-5p,the most upregulated miRNA in HP-EVs,directly combined the 3’untranslated region of TXNIP and demonstrated its critical protective role against hypoxia-mediated CM injury.Our results demonstrated that MI triggered TXNIP-mediated HIF-1αubiquitination and degradation in the CRM-1-mediated nuclear transport pathway in CMs,which led to aggravated injury and hypoxia tolerance in CMs in the early stage of MI.CONCLUSION The anti-apoptotic effects of HP-EVs in alleviating MI and the hypoxic conditions of CMs until reperfusion therapy may partly result from EV miR-224-5p targeting TXNIP. | Cheng-Yu Mao Tian-Tian Zhang Dong-Jiu Li En Zhou Yu-Qi Fan Qing He Chang-Qian Wang Jun-Feng Zhang | 2022 | World Journal of Stem Cells2022,14,2: | 1 |
| 20 | Study on the effect of dimple position on drag reduction of high-speed maglev train显示文摘Transient numerical simulations were carried out by placing dimples at the top,sides and bottoms of the tail car streamline area of a high-speed maglev train.The results of an improved delayed detached eddy simulation turbulence model using three-dimensional compressible Navier-Stokes and shear-stress transport K-Omega double equations were compared to the results of a wind tunnel test to verify the numerical simulation accuracy,within 5%of the ground truth,which is an acceptable precision range.The results show that dimples arranged on the streamline area atop the train tail car affected the locations at which the airflow at the top and bottom of the train met and weakened the strength of the wake.The aerodynamic drag and lift coefficient decreased by 3.40%and 4.27%,respectively.When the dimples were arranged on the streamline area at the sides or bottoms of the train tail car,they had little effect on the top of the tail car,so they did not destroy the balance of the airflow at the top and bottom.They also had little influence on the development of wake topology.Therefore,the aerodynamic drag and lift of the train changed little. | Dan Zhou Liliang Wu Changda Tan Tian’en Hu | 2021 | Transportation Safety and Environment2021,3,4: | 1 |
