| 3 | Dynamics of total culturable bacteria and its relationship with methylmercury in the soils of the water level fluctuation zone of the Three Gorges Reservoir显示文摘Field investigations were conducted to study the temporal and spatial distribution characteristics of total culturable bacteria(TCB)and its relationship with methylmercury(MeHg)in the soils of the water level fluctuation zone of the Three Gorges Reservoir.Different altitudes(170–180,170–175,165–170 and 160–165 m)in Zhenxi(Site 1),Shibaozhai(Site 2)and Tujing(Site 3),Chongqing,China were chosen as sampling sites.Results indicated that TCB did not have significant difference in the top(0–10 cm)and sub(10–20 cm)soil of the non-inundated area(175–180 m),but showing a significant difference in the water level fluctuation zone(\175 m,suggesting that water level fluctuation had an important effect on TCB.Moreover,TCB in soils of various altitudes of Site 1 and 2had significant difference,while for Site 3,this difference was not significant.And the difference of TCB in Site 2was much greater than that in Site 1.These results suggested that there were significant differences for TCB in soils of mainstream and tributaries.In addition,TCB in soils of 10–20 cm had significant or highly significant positive correlations with MeHg level(r C 0.762,P B 0.048),thus we assumed that there may be some aerobic microorganisms playing dominant roles in mercury methylation. | Yuping Xiang Hongxia Du Hong Shen Cheng Zhang Dingyong Wang | 2014 | Chinese Science Bulletin2014,59,24: | 10 |
| 4 | An experiment-library least-squares method on on-line coal element contents analysis显示文摘A new experiment-library least-squares(experiment-LLs) method used in the neutron inelastic-scattering and thermal-capture analysis(NITA) technique for on-line coal analysis was developed,which has significantly decreased the non-linear radiation effects.In this method,sixty samples with preset elemental contents were made,from whose experimental spectra twenty single-element spectrum libraries corresponding to twenty kinds of coal were built using the least-squares method.The spectrum of the unknown sample was analyzed based on these twenty libraries to estimate its element contents.With the initial estimated result,the procedure of developing library and analysis was iterated to build a new library with the closest element contents to the unknown sample.Hence the experiment-LLs method can reduce non-linear radiation effects.The experiment-LLs method was performed on an improved coal analysis system which was equipped with a long-life 14 MeV pulsed-neutron generator,a bulk BGO detector with a temperature controller,a moisture meter and coal-smoothing device.The precisions of this system for ash content,water content,volatile content and calorific value have reached 1.0wt%,0.5wt%,1.0wt%,350 kJ/kg,respectively. | WANG HuiDong LU JingBin LU YuPing YANG Dong MA KeYan YANG Kang LIU YuMin CHENG DaoWen | 2012 | Science China(Physics,Mechanics & Astronomy)2012,55,11: | 6 |
| 5 | Pseudo-noise preamble based joint frame and frequency synchronization algorithm in OFDM communication systems显示文摘Frame and frequency synchronization are essential for orthogonal frequency division multiplexing(OFDM) systems. The frame offset owing to incorrect start point position of the fast Fourier transform(FFT) window, and the carrier frequency offset(CFO) due to Doppler frequency shift or the frequency mismatch between the transmitter and receiver oscillators, can bring severe intersymbol interference(ISI) and intercarrier interference(ICI) for the OFDM system. Relying on the relatively good correlation characteristic of the pseudonoise(PN) sequence, a joint frame offset and normalized CFO estimation algorithm based on PN preamble in time domain is developed to realize the frame and frequency synchronization in the OFDM system. By comparison, the performances of the traditional algorithm and the improved algorithm are simulated under different conditions. The results indicate that the PN preamble based algorithm both in frame offset estimation and CFO estimation is more accurate, resourcesaving and robust even under poor channel condition, such as low signaltonoise ratio(SNR) and large normalized CFO. | Qingfeng Jing Ming Cheng Yuping Lu Weizhi Zhong Hongwei Yao | 2014 | Journal of Systems Engineering and Electronics2014,25,1: | 4 |
| 6 | A wireless, implantable optoelectrochemical probe for optogenetic stimulation and dopamine detection显示文摘Physical and chemical technologies have been continuously progressing advances in neuroscience research.The development of research tools for closed-loop control and monitoring neural activities in behaving animals is highly desirable.In this paper,we introduce a wirelessly operated,miniaturized microprobe system for optical interrogation and neurochemical sensing in the deep brain.Via epitaxial liftoff and transfer printing,microscale light-emitting diodes(micro-LEDs)as light sources and poly(3,4-ethylenedioxythiophene)polystyrene sulfonate(PEDOT:PSS)-coated diamond films as electrochemical sensors are vertically assembled to form implantable optoelectrochemical probes for real-time optogenetic stimulation and dopamine detection capabilities.A customized,lightweight circuit module is employed for untethered,remote signal control,and data acquisition.After the probe is injected into the ventral tegmental area(VTA)of freely behaving mice,in vivo experiments clearly demonstrate the utilities of the multifunctional optoelectrochemical microprobe system for optogenetic interference of place preferences and detection of dopamine release.The presented options for material and device integrations provide a practical route to simultaneous optical control and electrochemical sensing of complex nervous systems. | Changbo Liu Yu Zhao Xue Cai Yang Xie Taoyi Wang Dali Cheng Lizhu Li Rongfeng Li Yuping Deng He Ding Guoqing Lv Guanlei Zhao Lei Liu Guisheng Zou Meixin Feng Qian Sun Lan Yin Xing Sheng | 2020 | Microsystems & Nanoengineering2020,6,1: | 3 |
| 7 | Thermodynamic characterization of two novel spin-crossover complexes显示文摘Two novel FeII spin crossover complexes [Fe(L1)3](BF4)25H2O (1) and [Fe(L2)3](BF4)2·2H2O (2) with 4-NHR-1,2,4-triazole (R = isopropyl, L1; cyclohexyl, L2) were synthesized. 1 and 2 remain white at room temperature, whereas they turn purple at liquid temperature. Variable temperature optical detection and magnetic susceptibilities measurement show that the spin-crossover phenomenon for 1 was observed between 120 K and 170 K. The hysteresis loop is about 10 K. The Tc temperature of 2 is 190 K, but no thermal hysteresis loop was found. The molar thermodynamic functions and the microscopic parameters were obtained from the theoretical analysis in terms of the domain model, two level Ising model and regular solution model, respectively. | DING Bin, WANG Hongmei, YI Long, CHENG Peng, LI Licun, ZHAI Yuping, LIAO Daizheng, YAN Shiping & JIANG Zonghui Department of Chemistry, Nankai University, Tianjin 300071, China Correspondence should be addressed to Cheng Peng or Liao Daizheng (e-mail: pcheng@nankai.edu.cn) | 2003 | Chinese Science Bulletin2003,48,22: | 3 |
| 8 | Atmospheric isoprene and monoterpenes in a typical urban area of Beijing: Pollution characterization, chemical reactivity and source identification显示文摘Continuous observation of isoprene, α-pinene and β-pinene was carried out in a typical urban area of Beijing from March 2014 to February 2015, using an AirmoV OC online analyzer. Based on the analysis of the ambient level and variation characteristics of isoprene, α-pinene and β-pinene, the chemical reactivity was studied, and their sources were identified. Results showed that the concentrations of isoprene, α-pinene and β-pinene in the urban area of Beijing were lower than those in richly vegetated areas; the concentrations of isoprene were at a moderate level compared with those of previous studies of Beijing. Concentrations of isoprene, α-pinene and β-pinene showed different seasonal, monthly, daily and diurnal variations, and all of the three species showed higher level at night than those in the daytime as a whole, the variations of isoprene, α-pinene and β-pinene mainly influenced by emission of sources, photochemical reaction, and meteorological parameters. Isoprene was the largest contributor to the total OFP values than α-pinene and β-pinene. α-Pinene was the largest contributor to the total SOAFP values than isoprene and β-pinene in autumn, while isoprene was the largest one in other seasons. Isoprene, α-pinene and β-pinene were derived mainly from biological sources; and α-pinene level were also affected by industrial sources. To reduce the concentrations of isoprene, α-pinene and β-pinene, it is necessary to scientifically select urban green plant species, and more strict control measures should be taken to reduce the emission of α-pinene from industrial sources, such as artificial flavors and resins synthesis processes. | Xi Cheng Hong Li Yujie Zhang Yuping Li Weiqi Zhang Xuezhong Wang Fang Bi Hao Zhang Jian Gao Fahe Chai Xiaoxiu Lun Yizhen Chen Junyi Lv | 2018 | Journal of Environmental Sciences2018,30,9: | 3 |

| 11 | Water level fluctuations influence microbial communities and mercury methylation in soils in the Three Gorges Reservoir,China显示文摘Reservoirs tend to have enhanced methylmercury(MeHg) concentrations compared to natural lakes and rivers, and water level fluctuations can promote MeHg production. Until now, little research has been conducted on the effects of microorganisms in soils for the formation of MeHg during different drying and flooding alternating conditions in the Three Gorges Reservoir(TGR). This study aimed to understand how water level fluctuations affect soil microbial composition and mercury concentrations, and if such microbial variations are related to Hg methylation. The results showed that MeHg concentrations and the ratios of MeHg to THg(MeHg%) in soils were higher in the seasonally drying and flooding alternating areas(DFAs, 175–155 m) than those in the non-inundated(NIAs, > 175 m) and inundated areas(IAs, < 145 m). However, MeHg% in all samples was less than 1%, indicating that the Hg methylation activity in the soils of the TGR was under a low level. 454 highthroughput sequencing of 16 S rRNA gene amplicons showed that soil bacterial abundance and diversity were relatively higher in DFA compared to those in NIA and IA, and microbial community composition varied in these three areas. At the family level, those groups in Deltaproteobacteria and Methanomicrobia that might have many Hg methylators were also showed a higher relative abundance in DFA, which might be the reason for the higher MeHg production in these areas. Overall, our results suggested that seasonally water level fluctuations can enhance the microbial abundance and diversity, as well as MeHg production in the TGR. | Yuping Xiang Yongmin Wang Cheng Zhang Hong Shen Dingyong Wang | 2018 | Journal of Environmental Sciences2018,30,6: | 2 |
| 12 | Cooling effect of ballast revetment on the roadbed of Qinghai-Tibetan Railway显示文摘The data obtained through the roadbed surface thermal regime experiment (ROBSTREX), which was carried out at Beiluhe test section of Qinghai-Tibetan Railway from October to December in 2002, were used to estimate the cooling effect of ballast revetment on the roadbed. The results show that both riprap rock ballast revetment and crushed stone ballast revetment can reduce the temperature of the roadbed. But the cooling effect of riprap rock ballast revetment is better than that of crushed stone ballast revetment when the temperature of roadbed is higher. The cooling effect of crushed stone ballast revetment is better than that of riprap rock ballast revetment when the temperature of the roadbed is lower, especially at deeper roadbed layers. In the frozen season, the heat release from the roadbed also shows that the cooling effect of ballast revetment on the roadbed is obvious, and the cooling effect of crushed stone-ballast revetment on the roadbed is much evident than that of riprap rock ballast revetment. | HU Zeyong CHENG Guodong QIAN Zeyu WANG Jiemin WEI Guoan HOU Xuhong GU Lianglei YAN Yuping | 2004 | Science China Earth Sciences2004,47,z1: | 2 |
| 13 | Laboratory Simulation of the Formation Process of Surface Geochemical Anomalies Applied to Hydrocarbon Exploration显示文摘The formation mechanisms and processes of geochemical anomalies used as proxies in surface geochemistry exploration(SGE) have not been well understood. Previous studies cannot realize 3D measurement of microseeping hydrocarbons from reservoirs to the surface,which made it difficult to understand the features and pathways of deep hydrocarbon microseepages. Understanding the processes of hydrocarbon microseepages will contribute to the acceptance and effectiveness of surface geochemistry. Based on a simplified geological model of hydrocarbon microseepages,including hydrocarbon reservoir,direct caprock,overlying strata and Quaternary sediments,this work established a 3D experimental system to simulate the mechanisms and processes of deep hydrocarbon microseepes extending to the surface. The dispersive halos of microseeping hydrocarbons in the subsurface were adequately described by using this 3D experimental system. Results indicate that different migration patterns of hydrocarbons above the point gas source within the simulated caprock and overlying strata can be reflected by the ratio of i-butane to n-butane(i-C_4/n-C_4),which follow diffusion and infiltration(buoyancy) mechanisms. This is not the case for vertical measurement lines far from the point gas source. A vertical gas flow in the form of a plume was found during hydrocarbon microseepage. For sampling methods,the high-density grid sampling is favorable for delineating prospecting targets. Hydrocarbon infiltration or buoyancy flow occurs in the zones of infiltration clusters,coupling with a diffusion mechanism at the top of the water table and forming surface geochemical anomalies. These results are significant in understanding hydrocarbon microseepage and interpreting SGE data. | WANG Guojian TANG Yuping CHENG Tongjin TANG Junhong FAN Ming LU Li | 2016 | Acta Geologica Sinica(English Edition)2016,90,6: | 2 |
