| 1 | A Control Strategy for Grid-connected Inverters With LCL Filters显示文摘把LCL滤波器作为电压源型并网逆变器与电网的接口已受到广泛关注。与单电感L滤波器相比,利用电感值较小的LCL滤波器对入网电流的高次谐波具有显著的衰减效果,特别是在低开关频率的大功率并网逆变系统应用中更具明显优势,但是仅采用直接入网电流控制时,LCL滤波器接口的并网逆变器系统存在稳定性问题。该文采用电网侧电感电流和逆变侧电感电流双闭环控制策略对并网电流进行直接控制,电网侧电感电流作为外环更容易抑制并网电流的谐波因素,且可以直接控制入网电流的单位功率因数,采用逆变器侧电感电流作为内环可以增加系统阻尼,从而可抑制系统振荡,增加系统稳定性。对该方案进行系统建模,并深入分析了滤波器参数、控制器参数及系统稳定性之间的精确量化关系。仿真和实验结果表明,该控制策略既可有效抑制入网电流谐振和实现进网电流的高功率因数运行,同时又具有良好的稳态和动态性能。 | HU Xuefeng WEI Zheng CHEN Yihan GONG Chunying ZHANG Jiayan | 2012 | 中国电机工程学报2012，32，27： | 37 |
| 2 | Method of Fault Area & Section Location for Non-solidly Earthed Distribution System显示文摘中国中压配电网以架空线为主,多为小电流系统,单相接地故障占到电网故障总数的80%以上,但中国配网自动化系统基本上没有小电流接地故障定位功能,使配网自动化系统在提高可靠性的作用上大打折扣。给出一种小电流接地故障区段定位新方法,在线路上配置广域相量测量固定测点,获取小电流电网单相接地故障特征信息。基于测点相邻矩阵区段起始测点标识向量和故障路径标识向量概念,提出确定故障区间边界节点算法。物理模拟实验和挂网测试表明:该故障分区分段定位方法能够在线求解小电流接地故障段边界节点,缩小线路维护巡视范围。确定故障区间边界节点算法还可用于确定故障区相关负荷开关,为线路维护和馈线自动化提供依据。 | ZHENG Guping JIANG Chao LI Gang QI Zheng YANG Yihan | 2012 | 中国电机工程学报2012，32，13： | 28 |
| 3 | Synthesis of rod-like metal-organic framework(MOF-5)nanomaterial for efficient removal of U(Ⅵ):batch experiments and spectroscopy study显示文摘With the widespread application of radionuclide235 U(Ⅵ), it is inevitable that part of U(Ⅵ) is released into the natural environment. The potential toxicity and irreversibility impact on the natural environment has become one of the most forefront pollution problems in nuclear energy utilization. In this work, rod-like metal-organic framework(MOF-5) nanomaterial was synthesized by a solvothermal method and applied to efficiently adsorb U(Ⅵ) from aqueous solutions. The batch experimental results showed that the sorption of U(Ⅵ) on MOF-5 was strongly dependent on p H and independent of ionic strength, indicating that the dominant interaction mechanism was inner-sphere surface complexation and electrostatic interaction. The maximum sorption capacity of U(Ⅵ) on MOF-5 was 237.0 mg/g at p H 5.0 and T = 298 K, and the sorption equilibrium reached within 5 min. The thermodynamic parameters indicated that the removal of U(Ⅵ) on MOF-5 was a spontaneous and endothermic process. Additionally, the FT-IR and XPS analyses implied that the high sorption capacity of U(Ⅵ) on MOF-5 was mainly attributed to the abundant oxygen-containing functional groups(i.e., CAO and C@O). Such a facile preparation method and efficient removal performance highlighted the application of MOF-5 as a candidate for rapid and efficient radionuclide contamination's elimination in practical applications. | Yihan Wu Hongwei Pang Wen Yao Xiangxue Wang Shujun Yu Zhimin Yu Xiangke Wang | 2018 | Science Bulletin2018，63，13： | 21 |
| 4 | Geochronology and Geochemistry of Middle–Late Ordovician Granites and Gabbros in the Erguna Region,NE China:Implications for the Tectonic Evolution of the Erguna Massif显示文摘Zircon U-Pb ages, Hf isotope data and whole-rock major and trace element data for the Middle to Late Ordovician gabbros and granites in the Erguna Massif, NE China were presented in this paper. The petrogenesis of these rocks and the Early Paleozoic tectonic evolution of the massif were discussed. Zircons from the granites and gabbros are of magmatic origin based on their cathodoluminescence(CL) images. The 206Pb/238 U ages obtained from 20 spots on zircons from the granites range from 446±9 to 464±10 Ma, yielding a weighted mean age of 455±10 Ma; and 16 spots on zircons from the gabbros range from 465±10 to 466±7 Ma, yielding a weighted mean age of 465±2 Ma. Chemically, the Late Ordovician granites in the Erguna Massif are weakly peraluminous and similar to A-type granites. The granites and gabbros are all enriched in light rare earth elements and large ion lithophile elements(e.g., Rb, K), and depleted in heavy rare earth elements and high field strength elements(e.g., Nb, Ta, and Ti); they all exhibit marked negative Eu anomalies. Their zircon εHf(t) values range mainly from +1.86 to +6.21(for the granites) and +1.39 to +3.89(for the gabbros), except for one spot with a value of-0.27(for a gabbro). The TDM1 ages for the gabbros and TDM2 ages for the granites vary from 928 to 1 091 Ma and from 1 287 to 1 675 Ma, respectively. It is concluded that the primary magma of the granites could have been derived by partial melting of Mesoproterozoic newly accreted crustal material, whereas the primary magma of the gabbros originated by partial melting of a depleted mantle wedge that had been metasomatized by fluids derived from a subducted slab. These Middle–Late Ordovician granites and gabbros constitute a typical bimodal igneous rock association, implying an extensional environment that was probably related to the post-collisional development of the Erguna and Xing'an massifs in the early Early Paleozoic. | Shuo Zhao Wenliang Xu Wei Wang Jie Tang Yihan Zhang | 2014 | Journal of Earth Science2014，25，5： | 17 |
| 5 | Dual origins of Xiaoqinling gold-bearing quartz veins:Fluid inclusion evidence显示文摘Fluid inclusion research in Archean metamorphic rocks, Yanshanian granite and gold-bearing quartz veins shows that regional metamorphic fluids are high temperature and high saline, Yanshanian post-granitic fluids are CO2-bearing low saline, and ore-forming fluids are also CO2-rich low saline. In gold-barren/free parts of quartz veins in gold deposits, daughter mineral-bearing high saline inclusions related with metamorphic fluids remained. This proclaims quartz veins hosting gold ores might have been formed in early metamorphism, and overlapped or mineralized by late Yanshanian gold-bearing fluids. | Hongrui Fan Yihan Xie Rui Zhao Yinglan Wang | 2000 | Chinese Science Bulletin2000，45，15： | 17 |
| 6 | Zircon U-Pb dating of basement gneisses in the super-large Bayan Obo REE-Fe-Nb deposit, Inner Mongolia显示文摘Zircon U-Pb ages have been determined for basement gneisses in the Bayan Obo REE-Fe-Nb deposit. On the U-Pb concordia diagram data of three samples yield up-per intercept ages of 1948-1917 Ma. Thus, these basement gneisses are of Paleoproterozoic. Rock association of these basement gneisses includes tonalite, syenite and paragneiss, not belonging to a sedimentary package. It is more appro-priate to consider this association as a basement complex rather than a stratigraphic 'Group'. | WANG Kaiyi FAN Hongrui XIE Yihan LI Huimin | 2002 | Chinese Science Bulletin2002，47，3： | 16 |
| 7 | Application of Smith Predictor Based on Single Neural Network in Cold Rolling Shape Control显示文摘Flatness is one of the most important criterion factors to evaluate the quality of the steel strip. To improve the strip’s flatness quality, the most frequently used methodology is to employ the closed-loop automatic shape control system. However, in the shape control system, the shape-meter is always installed at the down way of the exit of the cold rolling mill and can not sense the changes of the strip flatness in the rolling gap directly. This kind of installation results in the delay of the feedback in the control system. Therefore, the stability and response performance of the system are strongly affected by the delay. At present, there is still no mature way to design controllers for systems with time delay. Although the conventional PID controller used in most practical applications has the capability to compensate the delay, the effect of the compensation is limited, especially for the systems with long time delay. Smith predictor, as a compensator for solving this problem, is now widely used in industry systems. However, the request of highly precise model of the system and the poor adaptive performance to the changes of related parameters limit the application of the Smith predictor in practice. In order to overcome the drawbacks of the Smith predictor, a new Smith predictor based on single neural network PID (SNN-PID) is proposed. Because the single neural network is employed into the Smith predictor to improve the controller’s self-adaptability, the adaptive capability to the varying parameters of the system is improved. Meanwhile, for the purpose of solving the problems such as time-consuming and complicated calculation of the neural networks in real time, the learning coefficient of neural network is divided into several stages as usually done in expert control system. Therefore, the control system can obtain fast response due to the improved calculation speed of the neural networks. In order to validate the performance of the proposed controller, the experiment is conducted on the shape control system in a 300 mm four-high reversing cold rolling mill. The experimental results show that the SNN-PID with Smith predictor controller can effectively compensate the delay effects and achieve better control performance than the conventional PID controller. | WANG Yiqun SUN FD LIU Jian SUN Menghui XIE Yihan | 2009 | Chinese Journal of Mechanical Engineering2009，22，2： | 14 |
| 8 | Implications for rock instability precursors and principal stress direction from rock acoustic experiments显示文摘The characteristics of rock instability precursors and the principal stress direction are very crucial for the prevention of geological disasters.This study investigated the qualitative relationship between rock instability precursors and principal stress direction through wave velocity in rock acoustic emission(AE)experiments.Results show that the wave velocity variation exhibits obvious anisotropic characteristics in 0%–20%and 60%–90%of peak strength due to the differences of stress-induced microcrack types.The amplitude of wave velocity variation is related to the azimuth and position of wave propagation path,which indicates that the principal stress direction can be identified by the anisotropic characteristics of wave velocity variations.Furthermore,the experiments also demonstrate that the AE event rate and wave velocity show quiet and stable variations in the elastic stage of rock samples,while they present a trend of active and unstable variations in the plastic stage.It implies that both the AE event rate and wave velocity are effective monitoring parameters for rock instability.The anisotropic characteristics of the wave velocity variation and AE event rate are beneficial complements for identifying the rock instability precursors and determining the principal stress direction,which provides a new analysis method for stability monitoring in practical rock engineering. | Longjun Dong Yongchao Chen Daoyuan Sun Yihan Zhang | 2021 | International Journal of Mining Science and Technology2021，31，5： | 10 |
| 9 | Short-range ordering and its effects on mechanical properties of high-entropy alloys显示文摘In this letter,we briefly summarize experimental and theoretical findings of fo rmation and characterization of short-range orderings(SROs)as well as their effects on the defo rmation behavior of high-entropy alloys(HEAs).We show that existence of SROs is a common yet key structural feature of HEAs,and tuning the degree of SROs is an effective way for optimizing mechanical properties of HEAs.In additional,the challenges concerning about formation mechanism and characterization of SROs in HEAs are discussed,and future research activities in this regard are also proposed. | Yuan Wu Fei Zhang Xiaoyuan Yuan Hailong Huang Xiaocan Wen Yihan Wang Mengyuan Zhang Honghui Wu Xiongjun Liu Hui Wang Suihe Jiang Zhaoping Lu | 2021 | Journal of Materials Science & Technology2021，，3： | 8 |
| 10 | In-situ reduction synthesis of manganese dioxide@polypyrrole core/shell nanomaterial for highly efficient enrichment of U(Ⅵ) and Eu(Ⅲ)显示文摘Radionuclides with long half-life are toxic,and thereby result in serious threat to human beings and ecological balance.Herein,a simple two-step synthesis method was used to prepare manganese dioxide@polypyrrole(Mn O_2@PPy)core/shell structures for efficient removal of U(Ⅵ)and Eu(Ⅲ)from aqueous solutions.The adsorption of U(Ⅵ)and Eu(Ⅲ)were investigated under different kinds of experimental conditions.The experimental results suggested that the adsorption of U(Ⅵ)and Eu(Ⅲ)on Mn O_2@PPy were greatly affected by p H.U(Ⅵ)adsorption on Mn O_2@PPy was independent of ionic strength at p H<6.0,and dependent on ionic strength at p H>6.0.However,Eu(Ⅲ)adsorption on Mn O_2@PPy was independent of ionic strength at the whole p H range of experimental conditions.The maximum adsorption capacities(q_(max))of U(Ⅵ)and Eu(Ⅲ)were 63.04 and54.74 mg g^(-1)at T=298 K,respectively.The BET,XRD,FTIR and XPS analysis evidenced that high adsorption capacities of U(Ⅵ)and Eu(Ⅲ)on Mn O_2@PPy were mainly due to high surface area and rich metal oxygen-containing group(i.e.,Mn–OH and Mn–O),and the interaction was mainly attributed to strong surface complexation and electrostatic interaction.This study highlighted the excellent adsorption performance of U(Ⅵ)and Eu(Ⅲ)on Mn O_2@PPy and could provide the reference for the elimination of radionuclides in real wastewater management. | Wen Yao Yihan Wu Hongwei Pang Xiangxue Wang Shujun Yu Xiangke Wang | 2018 | Science China Chemistry2018，61，7： | 7 |
| 11 | Effects of the Lithologic Character of Manufactured Sand on Properties of Concrete显示文摘Six representative parent rocks of sand, including limestone, quartzite, gneisses, granite, Basalt and Marble were selected to conduct a systematical research on the effects of various lithologies of manufactured sand on the workability, mechanism properties, volume stability and durability of manufacturedsand concrete. The experimental results show that the strength of manufactured-sand concrete is slightly higher than that of natural-sand concrete. Furthermore, substituting 15% cement of the concrete mixture with equal quantity of the six different lithology stone powder respectively, the data indicated that they can improve the concrete's workability, postpone the plastic cracking time, enhance the anti-cracking grade, and have no obvious effect on the properties of antifreeze and sulfate attack resistance but reduce the capability to resist chloride ion penetration. Moreover, the differences in concrete's workability, mechanism properties, volume stability and durability caused by various lithologies of manufactured sand and stone powder were not significant and the influence of lithology variety on the macro properties of concrete could be neglected eventually. | 王稷良 YANG Zhifeng LIU Yihan | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，6： | 6 |
| 12 | Pioneering function of Isl1 in the epigenetic control of cardiomyocyte cell fate显示文摘Generation of widely differing and specialized cell types from a single totipotent zygote involves large-scale transcriptional changes and chromatin reorganization. Pioneer transcription factors play key roles in programming the epigenome and facilitating recruitment of additional regulatory factors during successive cell lineage specification and differentiation steps. Here we show that Isl1 acts as a pioneer factor driving cardiomyocyte lineage commitment by shaping the chromatin landscape of cardiac progenitor cells. Using an Isl1 hypomorphic mouse line which shows congenital heart defects, genome-wide profiling of Isl1 binding together with RNA- and ATAC-sequencing of cardiac progenitor cells and their derivatives, we uncover a regulatory network downstream of Isl1 that orchestrates cardiogenesis. Mechanistically, we show that Isl1 binds to compacted chromatin and works in concert with the Brg1-Baf60c-based SWI/SNF complex to promote permissive cardiac lineage-specific alterations in the chromatin landscape not only of genes with critical functions in cardiac progenitor cells, but also of cardiomyocyte structural genes that are highly expressed when Isl1 itself is no longer present. Thus, the Isl1/Brg1-Baf60c complex plays a crucial role in orchestrating proper cardiogenesis and in establishing epigenetic memory of cardiomyocyte fate commitment. | Rui Gao Xingqun Liang Sirisha Cheedipudi Julio Cordero Xue Jiang Qingquan Zhang Luca Caputo Stefan Günther Carsten Kuenne Yonggang Ren Shoumo Bhattacharya Xuejun Yuan Guillermo Barreto Yihan Chen Thomas Braun Sylvia M.

| 14 | An all-round AI-Chemist with a scientific mind显示文摘The realization of automated chemical experiments by robots unveiled the prelude to an artificial intelligence(AI)laboratory.Several AI-based systems or robots with specific chemical skills have been demonstrated,but conducting all-round scientific research remains challenging.Here,we present an all-round AI-Chemist equipped with scientific data intelligence that is capable of performing basic tasks generally required in chemical research.Based on a service platform,the AI-Chemist is able to automatically read the literatures from a cloud database and propose experimental plans accordingly.It can control a mobile robot in-house or online to automatically execute the complete experimental process on 14 workstations,including synthesis,characterization and performance tests.The experimental data can be simultaneously analysed by the computational brain of the AI-Chemist through machine learning and Bayesian optimization,allowing a new hypothesis for the next iteration to be proposed.The competence of the AI-Chemist has been scrutinized by three different chemical tasks.In the future,the more advanced all-round AI-Chemists equipped with scientific data intelligence may cause changes to the landscape of the chemical laboratory. | Qing Zhu Fei Zhang Yan Huang Hengyu Xiao LuYuan Zhao XuChun Zhang Tao Song XinSheng Tang Xiang Li Guo He BaoChen Chong JunYi Zhou YiHan Zhang Baicheng Zhang JiaQi Cao Man Luo Song Wang GuiLin Ye WanJun Zhang Xin Chen Shuang Cong Donglai Zhou Huirong Li Jialei Li Gang Zou WeiWei Shang Jun Jiang Yi Luo | 2022 | National Science Review2022，9，10： | 5 |
| 15 | Effects of Huatan Tongluo decoction on vascular endothelial growth factor receptor 2 expression in synovial tissues of rats with collagen-induced arthritis显示文摘OBJECTIVE: To determine the therapeutic effect and potential mechanism of Huatan Tongluo decoction on rats with collagen-induced arthritis.METHODS: Forty specific pathogen-free Wistar rats were selected, and 10 were randomly selected as the control(group 1). The remaining rats were injected intradermally with emulsified type Ⅱ bovine collagen at the tail base and back, followed by a booster 7 d post first immunization. After establishing collagen-induced arthritis(CIA), rats were randomly divided into three groups(n = 10). The rats were treated orally for 30 d as follows: group 1, saline; group 2, model(saline); group 3, tripterygium polyglycoside(TP; 7.81 mg/kg, positive control);group 4, Huatan Tongluo decoction(HTTL; 7.5 g/kg). Body weight, ankle swelling and arthritis index were measured over the course of the study. The rats were sacrificed 30 d after treatment. Morphological changes in the synovium were observed by hematoxylin and eosin staining. Pannus formation and synovial thickness in the left ankle were observed by color Doppler ultrasoundVascular endothelial growth factor(VEGF) and VEGFR2 protein levels were measured by immunohistochemistry.VEGF/VEGFR2 mRNA levels were measured by real-time quantitative polymerase chain reaction.RESULTS: Compared with the model group, a significantly lower arthritis index was observed in the positive control group(P < 0.05) and HTTL group(P < 0.01), after treatment. Both positive control and HTTL reduced intra-articular pannus formation and synovial thickening. Furthermore, VEGF mRNA,and VEGFR2 protein and mRNA levels were significantly downregulated(P < 0.05) in the treatment groups.CONCLUSION: Inhibition of the expression of VEGF and VEGFR2 in synovial tissues and the formation of pannus and synovial hyperplasia may be part of the mechanism of HTTL for relieving the symptoms of rheumatoid arthritis in CIA rats. | Chen Jinchun Qiu Mingshan Li Yihan Zhang Qian Zhang Yiyan Lin Shuangjie Zhang Shaohong Qian Lixia Gao Hai Li Liang-cheng | 2019 | Journal of Traditional Chinese Medicine2019，39，2： | 4 |
| 16 | Surface acoustic wave humidity sensors based on uniform and thickness controllable graphene oxide thin films formed by surface tension显示文摘Graphene oxide(GO)is a promising candidate for humidity sensing,and the uniformity and thickness of GO films are important for the reproducibility and test signal strength of humidity sensors.In this paper,uniform and thicknesscontrollable GO films are first formed by the surface tension of different concentrations of GO solution and then transferred to surface acoustic wave(SAW)humidity sensors.This GO film formation and transfer process has very good repeatability and stability,as evidenced by the humidity response of the sensors.With the help of the uniform and highly oxidized GO film,the humidity sensors show a significantly high sensitivity(absolute sensitivity of 25.3 kHz/%RH and relative sensitivity of 111.7 p.p.m./%RH)in a wide test range from 10%RH to 90%RH with very little hysteresis(<1%RH).The sensors achieve good reversibility,excellent short-term repeatability and stability.Moreover,the humidity sensors also show a fast response and recovery time of<10 s. | Xianhao Le Yihan Liu Li Peng Jintao Pang Zhen Xu Chao Gao Jin Xie | 2019 | Microsystems & Nanoengineering2019，5，1： | 4 |
| 17 | A pH-sensitive supramolecular nanosystem with chlorin e6 and triptolide co-delivery for chemo-photodynamic combination therapy显示文摘The combination of Ce6,an acknowledged photosensitizer,and TPL,a natural anticancer agent,has been demonstrated as a useful strategy to reinforce the tumor growth suppression,as well as decrease the systemic side effects compared with their monotherapy.However,in view of the optimal chemo-photodynamic combination efficiency,there is still short of the feasible nanovehicle to steadily co-deliver Ce6 and TPL,and stimuli-responsively burst release drugs in tumor site.Herein,we described the synergistic antitumor performance of a pH-sensitive supramolecular nanosystem,mediated by the host–guest complexing betweenβ-CD and acid pH-responsive amphiphilic co-polymer mPEG-PBAE-mPEG,showing the shell–core structural micelles with the tightβ-CD layer coating.Both Ce6 and TPLwere facilely co-loaded into the spherical supramolecular NPs(TPL+Ce6/NPs)by one-step nanoprecipitation method,with an ideal particle size(156.0 nm),acid pH-responsive drug release profile,and enhanced cellular internalization capacity.In view of the combination benefit of photodynamic therapy and chemotherapy,as well as co-encapsulation in the fabricated pH-sensitive supramolecular NPs,TPL+Ce6/NPs exhibited significant efficacy to suppress cellular proliferation,boost ROS level,lower MMP,and promote cellular apoptosis in vitro.Particularly,fluorescence imaging revealed that TPL+Ce6/NPs preferentially accumulated in the tumor tissue area,with higher intensity than that of free Ce6.As expected,upon 650-nm laser irradiation,TPL+Ce6/NPs exhibited a cascade of amplified synergistic chemo-photodynamic therapeutic benefits to suppress tumor progression in both hepatoma H22 tumor-bearingmice and B16 tumor-bearingmice.More importantly,lower systemic toxicitywas found in the tumor-bearingmice treated with TPL+Ce6/NPs.Overall,the designed supramolecular TPL+Ce6/NPs provided a promising alternative approach for chemo-photodynamic therapy in tumor treatment. | Yihan Wu Jingjing Li Xuemei Zhong Jinfeng Shi Yanfen Cheng Chenglin He Jiaxin Li Liang Zou Chaomei Fu Meiwan Chen Jinming Zhang Huile Gao | 2022 | Asian Journal of Pharmaceutical Sciences2022，17，2： | 4 |
| 18 | TRIM35 mediates protection against influenza infection by activating TRAF3 and degrading viral PB2显示文摘Tripartite motif(TRIM)family proteins are important effectors of innate immunity against viral infections.Here we identified TRIM35 as a regulator of TRAF3 activation.Deficiency in or inhibition of TRIM35 suppressed the production of type I interferon(IFN)in response to viral infection.777m35-deficient mice were more susceptible to influenza A virus(IAV)infection than were wild-type mice.TRIM35 promoted the RIG-Imediated signaling by catalyzing Lys63-linked polyubiquitination of TRAF3 and the subsequent formation of a signaling complex with VISA and TBK1.IAV PB2 polymerase countered the innate antiviral immune response by impeding the Lys63-linked polyubiquitination and activation of TRAF3.TRIM35 mediated Lys48-linked polyubiquitination and proteasomal degradation of IAV PB2,thereby antagonizing its suppression of TRAF3 activation.Our in vitro and in vivo findings thus reveal novel roles of TRIM35,through catalyzing Lys63-or Lys48-linked polyubiquitination,in RIG-I antiviral immunity and mechanism of defense against IAV infection. | Nan Sun Li Jiang Miaomiao Ye Yihan Wang Guangwen Wang Xiaopeng Wan Yuhui Zhao Xia Wen Libin Liang Shujie Ma Liling Liu Zhigao Bu Hualan Chen Chengjun Li | 2020 | Protein & Cell2020，11，12： | 4 |
| 19 | GPU-CA model for large-scale land-use change simulation显示文摘Land-use change simulation for large-scale regions(i.e.provincial regions or countries) is very useful for many global studies.Such simulation,however,is affected by computational capability of general computers.This paper proposes a method to implement cellular automata(CA) for land use change simulation based on graphics processing units(GPUs).This method can be applied to large-scale land-use change simulations by combining the latest GPU high-performance computing technology and CA.We carried out the experiments by simulating land-use change processes at a provincial scale.This involves a lot of sophisticated techniques,such as model mapping,and computational procedure of GPU-CA model.This proposed model has been validated by land-use change simulation in Guangdong Province,China.The comparison indicates that the GPU-CA model is faster than traditional CA by 30 times.Such improvement is crucial for land-use change simulations in provincial regions and countries.The outputs of the simulation can be further used to provide information to other global change models. | LI Dan LI Xia LIU XiaoPing CHEN YiMin LI ShaoYing LIU Kai QIAO JiGang ZHENG YiZhong ZHANG YiHan LAO ChunHua | 2012 | Chinese Science Bulletin2012，57，19： | 4 |
| 20 | Numerical Simulation and Optimization of Staged Combustion and NO_x Release Characteristics in Precalciner显示文摘In order to study the combustion characteristics in a precalciner, the temperature and composition field in a typical Trinal-sprayed calciner were numerically analysed. The results obtained by simulation were compared to actual measurements and the simulated results were in good agreement with the measured ones. The results indicated that the aerodynamic flow field in the precalciner is satisfactory, and a symmetrical reflux occurs in the shrinkage zone of the precalciner because of air staging, which can increase the residence time of the solid particles. The temperature distribution in the furnace is uniform, and the average temperature is greater than 1200 K, which can satisfy the conditions for the pulverised coal combustion and raw material decomposition. The mass fraction distribution of oxygen, carbon monoxide, and carbon dioxide in the precalciner is closely related to the temperature distribution. The concentration of nitrogen oxides(NO_x) exhibits a trend of increasing, decreasing and then increasing, and finally tending to a stable level. Within a certain velocity range, the average temperature in the precalciner and the decomposition efficiency of the raw material increase as the flue gas velocity increases. When the flue gas velocity is 24 m/s, the overall performance of the precalciner is optimal. | WANG Weishu LIAO Yihan LIU Jun HUANG Zhihao TIAN Miao | 2019 | Journal of Thermal Science2019，28，5： | 4 |
