| 1 | Shock tube study of kerosene ignition delay at high pressures显示文摘Ignition delay times of China No.3 aviation kerosene were measured behind reflected shock waves using a heated high-pressure shock tube.Experimental conditions covered a wider temperature range of 820-1500 K,at pressures of 5.5,11 and 22 atm,equivalence ratios of 0.5,1.0 and 1.5,and oxygen concentration of 20%.Adsorption of kerosene on the shock tube wall was taken into account.Ignition delay times were determined from the onset of the excited radical OH emission in conjunction with the pressure profiles.The experimental results of ignition delay time were correlated with the equations:11 0.22 1.09 2 3.2 10 [Keros ene ] [O2] exp(69941 RT) and 7 0.88 0.23 4.72 10 P exp(62092 RT).The current measurements provide the ignition delay behavior of China No.3 aviation kerosene at high pressures and air-like O2 concentration. | LIANG JinHu WANG Su HU HongHao ZHANG ShengTao FAN BingCheng CUI JiPing | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，6： | 13 |
| 2 | 土壤颗粒分布体积分形维数与数量分形维数之间的关系(英文)显示文摘土壤的体积颗粒分布(PSD)可用于同时确定数量分形维数(DN)和体积分形维数(DV)。以往的试验和理论研究均未直接比较DV和DN的关系。为建立DV和DN的关系并分析其参数的敏感程度,在中国各地取了12种不同质地土壤,利用激光粒度仪进行了测定。提出了含3个参数Rupper(颗粒半径的上限),Ri(第i个半径)和Rlower(半径下限)的DV-DN理论关系,该关系可说明为什么DN可能大于3。在未调整的幂定律范围内(PLR),DV的幂定律半径为38.6~85.8μm,DN的幂定律半径为53.2~358μm,估算的DV值(2.18~2.69)比DN值(2.38~3.19)小。调整后的PLR比未调整的窄。在调整的PLRs范围内,估算的DV值变化范围为2.11~2.56,而DN变化范围为2.28~3.02。调整和未调整PLRs得出的DV和DN的差异说明,Rupper,Rlower,Ri和Rlower/Rupper均可能影响DV与DN关系,有必要进行参数的敏感性分析。进行敏感性分析可基于敏感系数(C)来鉴别DV-DN关系中各参数改变所引起的DV和DN相对变化,从而找出对该关系影响最大的参数。就不同情况下计算的C值而言,Rupper是影响DN值的最重要参数,小的Rupper值可能导致估算DN的准确度降低。PLR范围越大,DN的估算越准确。根据DV估算DN的相对误差的绝对值在12%范围内,说明得出的DV-DN理论关系是正确的。 | 李毅 李敏 Si Bingcheng 贺缠生 | 2012 | 农业工程学报2012，28，23： | 7 |
| 3 | Seasonal and Interannual Variations of Carbon Exchange over a Rice–Wheat Rotation System on the North China Plain显示文摘Rice–wheat(R–W) rotation systems are ubiquitous in South and East Asia,and play an important role in modulating the carbon cycle and climate. Long-term,continuous flux measurements help in better understanding the seasonal and interannual variation of the carbon budget over R–W rotation systems. In this study,measurements of CO2 fluxes and meteorological variables over an R–W rotation system on the North China Plain from 2007 to 2010 were analyzed. To analyze the abiotic factors regulating Net Ecosystem Exchange(NEE),NEE was partitioned into gross primary production(GPP) and ecosystem respiration. Nighttime NEE or ecosystem respiration was controlled primarily by soil temperature,while daytime NEE was mainly determined by photosythetically active radiation(PAR). The responses of nighttime NEE to soil temperature and daytime NEE to light were closely associated with crop development and photosynthetic activity,respectively. Moreover,the interannual variation in GPP and NEE mainly depended on precipitation and PAR. Overall,NEE was negative on the annual scale and the rotation system behaved as a carbon sink of 982 g C m-2per year over the three years. The winter wheat field took up more CO2 than the rice paddy during the longer growing season,while the daily NEE for wheat and rice were-2.35and-3.96 g C m-2,respectively. After the grain harvest was subtracted from the NEE,the winter wheat field became a moderately strong carbon sink of 251–334 g C m-2per season,whereas the rice paddy switched to a weak carbon sink of107–132 per season. | CHEN Chen LI Dan GAO Zhiqiu Jianwu TANG GUO Xiaofeng WANG Linlin WAN Bingcheng | 2015 | Advances in Atmospheric Sciences2015，32，10： | 6 |
| 4 | Full-duplex light communication with a monolithic multicomponent system显示文摘A monolithic multicomponent system is proposed and implemented on a III-nitride-on-silicon platform,whereby two multiple-quantum-well diodes(MQW-diodes)are interconnected by a suspended waveguide.Both MQW-diodes have an identical low-In-content InGaN/Al0.10Ga0.90N MQW structure and are produced by the same fabrication process flow.When appropriately biased,both MQW-diodes operate under a simultaneous emission-detection mode and function as a transmitter and a receiver at the same time,forming an in-plane full-duplex light communication system.Real-time full-duplex audio communication is experimentally demonstrated using the monolithic multicomponent system in combination with an external circuit. | Yongjin Wang Xin Wang Bingcheng Zhu Zheng Shi Jialei Yuan Xumin Gao Yuhuai Liu Xiaojuan Sun Dabing Li Hiroshi Amano | 2018 | Light(Science & Applications)2018，7，1： | 5 |
| 5 | High-Q microresonators on 4H-silicon-carbide-on-insulator platform for nonlinear photonics显示文摘The realization of high-quality(Q)resonators regardless of the underpinning material platforms has been a ceaseless pursuit,because the high-Q resonators provide an extreme environment for confining light to enable observations of many nonlinear optical phenomenon with high efficiencies.Here,photonic microresonators with a mean Q factor of 6.75×10^(6)were demonstrated on a 4H-silicon-carbide-on-insulator(4H-SiCOI)platform,as determined by a statistical analysis of tens of resonances.Using these devices,broadband frequency conversions,including second-,third-,and fourth-harmonic generations have been observed.Cascaded Raman lasing has also been demonstrated in our SiC microresonator for the first time,to the best of our knowledge.Meanwhile,by engineering the dispersion properties of the SiC microresonator,we have achieved broadband Kerr frequency combs covering from 1300 to 1700nm.Our demonstration represents a significant milestone in the development of SiC photonic integrated devices. | Chengli Wang Zhiwei Fang Ailun Yi Bingcheng Yang Zhe Wang Liping Zhou Chen Shen Yifan Zhu Yuan Zhou Rui Bao Zhongxu Li Yang Chen Kai Huang Jiaxiang Zhang Ya Cheng Xin Ou | 2021 | Light(Science & Applications)2021，10，8： | 4 |
| 6 | Microstructure and mechanical properties at elevated temperature of Mg-Al-Ni alloys prepared through powder metallurgy显示文摘Mg-Al-Ni alloys were prepared by powder metallurgy, and their microstructure and elevated temperature mechanical properties were investigated. Results indicate that, in addition to α-Mg matrix, both coarse Al_3Ni_2 particles and fine Al Ni nano-particles exist in the Mg-Al-Ni alloys. The strength at 150?C is improved with the increase in Ni content. Mg-18.3Al-8Ni alloy possesses a compressive strength of234.7 MPa and a yield strength of 146.5 MPa. Plasticity is also improved with a low concentration of Ni. Mg-11.3Al-2Ni alloy possesses a compression ratio of 17.3%. The phases of Al_3Ni_2 and Al Ni in the alloys block the movements of grain boundaries and dislocations during the deformation at elevated temperature. The existence of Al Ni phase provides a non-basal slip system, leading to the improvement in plasticity. Finally, the formation mechanism of Al-Ni phases in the process is discussed with thermodynamics and kinetics. | Legan Hou Bingcheng Li Ruizhi Wu Lin Cui Peng Ji Ruiying Long Jinghua Zhang Xinlin Li Anping Dong Baode Sun | 2017 | Journal of Materials Science & Technology2017，33，9： | 4 |
| 7 | Calibration of the simulation parameters of the particulate materials in film mixed materials显示文摘In order to obtain accurate contact parameters of a particulate material in residual film mixture collected by cotton field machine in Xinjiang,the angle of repose test and inclined plane test were carried out.In the tests,the angles of repose of the particulate material with the water content of(6.26±1.5)%and(14.1±2.1)%were measured respectively,as well as the static sliding friction angle between the particulate material and the residual film.At the same time,the EDEM software was used to calibrate the coefficient of restitution,static friction coefficient and dynamic friction coefficient between the material and the film.Then,the second-order response model between contact parameters and the angle of repose and static sliding friction angle was constructed.In addition,the optimal contact parameters between the granular materials and the mulch were obtained by fitting the physical test data.The results indicated that the errors between the physical test results and the numerical simulation results are small.It was proved that the second-order response model could predict the repose angle of granular materials and the static sliding friction angle between granular materials and farmland film.This study could provide theoretical support for the subsequent model construction of the residual film mixture collected by the cotton field machine. | Rongqing Liang Xuegeng Chen Peng Jiang Bingcheng Zhang Hewei Meng Xiangbin Peng Za Kan | 2020 | International Journal of Agricultural and Biological Engineering2020，13，4： | 3 |
| 8 | A metasurface-based light-to-microwave transmitter for hybrid wireless communications显示文摘Signal conversion plays an important role in many applications such as communication,sensing,and imaging.Realizing signal conversion between optical and microwave frequencies is a crucial step to construct hybrid communication systems that combine both optical and microwave wireless technologies to achieve better features,which are highly desirable in the future wireless communications.However,such a signal conversion process typically requires a complicated relay to perform multiple operations,which will consume additional hardware/time/energy resources.Here,we report a light-to-microwave transmitter based on the time-varying and programmable metasurface integrated with a high-speed photoelectric detection circuit into a hybrid.Such a transmitter can convert a light intensity signal to two microwave binary frequency shift keying signals by using the dispersion characteristics of the metasurface to implement the frequency division multiplexing.To illustrate the metasurface-based transmitter,a hybrid wireless communication system that allows dual-channel data transmissions in a light-to-microwave link is demonstrated,and the experimental results show that two different videos can be transmitted and received simultaneously and independently.Our metasurface-enabled signal conversion solution may enrich the functionalities of metasurfaces,and could also stimulate new information-oriented applications. | Xin Ge Zhang Ya Lun Sun Bingcheng Zhu Wei Xiang Jiang Qian Yu Han Wei Tian Cheng-Wei Qiu Zaichen Zhang Tie Jun Cui | 2022 | Light(Science & Applications)2022，11，6： | 3 |
| 9 | Diurnal and seasonal variations of soil respiration rate under different row-spacing in a Panicum virgatum L. field on semi-arid Loess Plateau of China显示文摘Soil respiration(SR) in crop field is affected by environmental factors, agronomic practices and crop types. To clarify how planting density affects the SR dynamics in switchgrass(Panicum virgatum L.) field on the semi-arid Loess Plateau, this research investigated diurnal and seasonal changes of soil respiration rate(RS) under three different row-spacing treatments(20, 40 and 60 cm) in the fourth growing year of switchgrass. Results showed that RS presented a pronounced seasonality under all row-spacing treatments. The highest daily average RS values appeared in August, while the lowest(P<0.05) were in September for each row-spacing. Diurnal variations of RS exhibited single-peak curves in each month. Daily average RS increased significantly as row-spacing enlarged during May and August but there was no significant difference among row-spacing treatments in September. Soil water storage in the depth of 0–100 cm had no significant difference(P>0.05) among the row-spacing treatments, and similar results were found for soil temperature in 0–15 cm soil depth. Soil respiration temperature sensitivity(Q_(10)) values were 1.0–3.7 during the growing months, which were strongly correlated with air temperature in May and June and the soil temperature at 15 cm depth in August. Higher aboveground biomass production and lower RS in most growth months indicated that 20 cm row-spacing treatment was beneficial for increasing the carbon fixation in switchgrass field. Results also implied that it is necessary to take into account the influence of phenology and root growth of switchgrass on soil respiration for accurately evaluating the carbon cycle in the region. | HUANG Jin GAO Zhijuan CHEN Ji ZHANG He XU Bingcheng | 2016 | Journal of Arid Land2016，8，3： | 3 |

| 15 | Effects of water and nitrogen on growth and relative competitive ability of introduced versus native C_(4)grass species in the semi-arid Loess Plateau of China显示文摘Switchgrass is an introduced C_(4)grass in the semi-arid Loess Plateau of China,but there is a lack of information to assess its ecological invasive risk.In this study,Old World bluestems(native C_(4)grass)and switchgrass were sowed at five mixture ratios(8:0,6:2,4:4,2:6 and 0:8)under two soil water levels(80%field capacity(FC)and 40%FC)and two nitrogen(N)treatments(0 and 100 mg N/kg dry soil,termed N0-unfertilized and N1-fertilized treatments,respectively)in a pot experiment in 2012.Biomass,root morphological traits and relative competitive abilities of these two species were analyzed.Results showed that biomass of both species was significantly greater under 80%FC or N fertilization,and switchgrass had a relatively larger root:shoot ratio(RSR).Total root length(TRL)and root surface area(RSA)of switchgrass were significantly higher under 80%FC irrespective of N treatment,while those of Old World bluestems were only significantly higher under N fertilization.N had no significant effect on TRL and RSA of switchgrass,while RSA of Old World bluestems significantly increased under 80%FC and N fertilization.Under 40%FC and N0-unfertilized treatment,the aggressivity of Old World bluestems was larger than zero at 2:6 and 4:4 mixture ratios of two species,whereas it was close to zero at 6:2 mixture ratio.Root competitive ability of switchgrass significantly increased under 80%FC or N fertilization.The aggressivity of Old World bluestems was negative at 6:2 mixture ratio under 80%FC and N fertilization,while it was positive at 2:6 mixture ratio.Switchgrass may become more aggressive when N deposition or rainfall increases,while a proper mixture ratio with appropriate water and N management could help with grassland management in the semi-arid Loess Plateau. | DING Wenli XU Weizhou GAO Zhijuan XU Bingcheng | 2021 | Journal of Arid Land2021，13，7： | 1 |

| 19 | Light-controllable time-domain digital coding metasurfaces显示文摘Programmable metasurfaces enable real-time control of electromagnetic waves in a digital coding manner,which are suitable for implementing time-domain metasurfaces with strong harmonic manipulation capabilities.However,the time-domain metasurfaces are usually realized by adopting the wired electrical control method,which is effective and robust,but there are still some limitations.Here,we propose a light-controllable time-domain digital coding metasurface consisting of a full-polarization dynamic metasurface and a high-speed photoelectric detection circuit,from which the microwave reflection spectra are manipulated by time-varying light signals with periodic phase modulations.As demonstrated,the light-controllable timedomain digital coding metasurface is illuminated by the light signals with two designed time-coding sequences.The measured results show that the metasurface can well generate symmetrical harmonics and white-noise-like spectra,respectively,under such cases in the reflected wave.The proposed lightcontrollable time-varying metasurface offers a planar interface to tailor and link microwaves with lights in the time domain,which could promote the development of photoelectric hybrid metasurfaces and related multiphysics applications. | Xin Ge Zhang Ya Lun Sun Bingcheng Zhu Wei Xiang Jiang Zaichen Zhang Tie Jun Cui | 2022 | Advanced Photonics2022，4，2： | 1 |
| 20 | A reversed phase/hydrophilic interaction/ion exchange mixed-mode stationary phase for liquid chromatography显示文摘A reversed phase (RP)/hydrophilic interaction (HILIC)/ion exchange (IEX) mixed tri-mode stationary phase (TMSP) has been prepared via a divergent synthesis scheme starting from propylamine on silica then by amine-epoxy reactions with 1,4-butanedioldiglycidyl ether and tertiary amines (N,Ndimethyldecylamine, DMDA). Its retention mechanism was found to follow RP/HILIC/IEX mixed-mode.The stop-flow test revealed that TMSP had good compatibility with 100% aqueous mobile phase. It demonstrated effective separation towards several kinds of compounds or drug molecules and their counterions within a single run. | Sainan Zhang Feifang Zhang Bingcheng Yang Xinmiao Liang | 2019 | Chinese Chemical Letters2019，30，2： | 1 |
