| 3 | Dynamic analysis of a flameless combustion model combustor显示文摘Flameless combustion is a new technology with the following advantages:1)Ultra-low emissions of both NOX and CO;2)fuel flexibility,from liquid fuels,natural gas to hydrogen-rich syngas;3)lower possibility of flashback and thermoacoustic oscillations.In this paper,we focus on the dynamic characteristics of a flameless model combustor.Experimental results show that flameless combustion can lower emissions while maintaining combustion stability.However,combining a pilot flame with flameless combustion may excite thermoacoustic instability. | CUI YuFeng 1* ,LüXuan 1,2 ,XU Gang 1 &NIE ChaoQun 1 1 Institute of Engineering Thermophysics,Chinese Academy of Sciences,Beijing 100190,China 2Graduate School of the Chinese Academy of Sciences,Beijing 100190,China | 2010 | Science China(Technological Sciences)2010，53，8： | 5 |
| 4 | Early therapeutic interventions of traditional Chinese medicine in COVID-19 patients:A retrospective cohort study显示文摘Objective:To observe the early interventions of traditional Chinese Medicine(TCM)on the conversion time of nucleic acid in patients with coronavirus disease 2019(COVID-19),and find possible underlying mechanisms of action.Methods:A retrospective cohort study was conducted on 300 confirmed COVID-19 patients who were treated with TCM,at a designated hospital in China.The patients were categorized into three groups:TCM1,TCM2 and TCM3,who respectively received TCM interventions within 7,8–14,and greater than15 days of hospitalization.Different indicators such as the conversion time of pharyngeal swab nucleic acid,the conversion time of fecal nucleic acid,length of hospital stay,and inflammatory markers(leukocyte count,and lymphocyte count and percentage)were analyzed to observe the impact of early TCM interventions on these groups.Results:The median conversion times of pharyngeal swab nucleic acid in the three groups were 5.5,7 and16 d(P<0.001),with TCM1 and TCM2 being statistically different from TCM3(P<0.01).TCM1(P<0.05)and TCM3(P<0.01)were statistically different from TCM2.The median conversion times of fecal nucleic acid in the three groups were 7,9 and 17 d(P<0.001).Conversion times of fecal nucleic acid in TCM1 were statistically different from TCM3 and TCM2(P<0.01).The median lengths of hospital stay in the three groups were 13,16 and 21 d(P<0.001).TCM1 and TCM2 were statistically different from TCM3(P<0.01);TCM1 and TCM3 were statistically different from TCM2(P<0.01).Both leucocyte and lymphocyte counts increased gradually with an increase in the length of hospital stay in TCM1 group patients,with a statistically significant difference observed at each time point in the group(P<0.001).Statistically significant differences in lymphocyte count and percentage in TCM2(P<0.001),and in leucocyte count(P=0.043)and lymphocyte count(P=0.038)in TCM3 were observed.The comparison among the three groups showed a statistically significant difference in lymphocyte percentage on the third day of admission(P=0.044).Conclusion:In this study,it was observed that in COVID-19 patients treated with a combination of Chinese and Western medicines,TCM intervention earlier in the hospital stay correlated with faster conversion time of pharyngeal swab and fecal nucleic acid,as well as shorter length of hospital stay,thus helping promote faster recovery of the patient.The underlying mechanism of action may be related to improving inflammation in patients with COVID-19. | Miao-yan Shi Shi-qi Sun Wei Zhang Xing Zhang Gui-hua Xu Xuan Chen Zi-jian Su Xiu-ming Song Lu-jiong Liu Yi-bao Zhang Yi-le Zhang Meng Sun Qi Chen Yan Xue Hua Lü Wei-an Yuan Xiao-rong Chen Yun-fei Lu | 2021 | Journal of Integrative Medicine2021，19，3： | 4 |
| 5 | Molecular dynamics simulation and continuum modelling of granular surface flow in rotating drums显示文摘Numerical simulations of granular flows in rotating drums operated at medium to high rates (Fr=0.1― 0.2) have been carried out by using a Molecular Dynamics (MD) algorithm that incorporates inelastic particle interactions, sliding friction and rolling friction. The results indicate that the behavior of granular flow in rotating drums can be classified into two distinct zones: a shear active layer at the bed surface and a quasi-static plug flow region adjacent to the wall. The residence time of a tracer particle in the active layer is approximately a third or a half of that in the plug flow region. The thickness of the active layer at mid-chord is about 0.57―0.61 times that of the plug flow region. It is found that all cases simulated in this work are in the rolling-cascading intermediate regime instead of the pure rolling re-gime. The simulated tangential velocity at the mid-chord is also compared with experimental results reported in the literature and good agreement has been obtained. Based on the MD simulations and experimental results, a continuum approach has also been developed. It is shown that the behavior of granular solids in the plug flow region experiences plastic deformation along the radial direction from the wall with the velocity profiles well described by an exponential function, whereas the active layer velocity follows a simple expression for the Couette shear flow. Discussion has also been made on the granular temperature and concentration profiles. | LI ShuiQing YAO Qiang CHEN Bing ZHANG Xuan DING Y L | 2007 | Chinese Science Bulletin2007，52，5： | 3 |
| 6 | Effect of La on Partial Oxidation of Ethanol to Hydrogen over Ni/Fe Catalysts显示文摘The partial oxidation of ethanol to hydrogen was investigated over Ni/Fe/La catalysts prepared by the co precipitation method. The effects of introduction of La promoter and the reaction temperature on the catalytic performance were studied. It was found that the introduction of La into Ni/Fe catalysts is helpful to increase the selectivity to hydrogen and the stability of the catalysts. The results of XRD and XPS characterization show that the structure of the catalyst was changed during the reaction. The existence of LaFeO 3 species is possibly the main reason of the increase of the catalyst stability. | WANG Wei ping, WANG Zhi fei, DING Yan and LU¨ Gong xuan ** State Key Laboratory for Oxo Synthesis and Selective Oxidation, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, Lanzhou 730000, P.
