| 1 | Agriculture Green Development: a model for China and the world显示文摘Realizing sustainable development has become a global priority.This holds,in particular,for agriculture.Recently,the United Nations launched the Sustainable Development Goals(SDGs),and the Nineteenth National People’s Congress has delivered a national strategy for sustainable development in China—realizing green development.The overall objective of Agriculture Green Development(AGD)is to coordinate'green'with'development'to realize the transformation of current agriculture with high resource consumption and high environmental costs into a green agriculture and countryside with high productivity,high resource use efficiency and low environmental impact.This is a formidable task,requiring joint efforts of government,farmers,industry,educators and researchers.The innovative concept for AGD will focus on reconstructing the whole crop-animal production and food production-consumption system,with the emphasis on high thresholds for environmental standards and food quality as well as enhanced human well-being.This paper addresses the significance,challenges,framework,pathways and potential solutions for realizing AGD in China,and highlights the potential changes that will lead to a more sustainable agriculture in the future.Proposals include interdisciplinary innovations,whole food chain improvement and regional solutions.The implementation of AGD in China will provide important implications for the countries in developmental transition,and contribute to global sustainable development. | Jianbo SHEN Qichao ZHU Xiaoqiang JIAO Hao YING Hongliang WANG Xin WEN Wen XU Tingyu LI Wenfeng CONG Xuejun LIU Yong HOU Zhenling CUI Oene OENEMA William JDAVIES Fusuo ZHANG | 2020 | Frontiers of Agricultural Science and Engineering2020，7，1： | 18 |
| 2 | Screening beneficial bacteriostatic lactic acid bacteria in the intestine and studies of bacteriostatic substances显示文摘Lactic acid bacteria(LAB)are a representative probiotic.As the dominant flora in the human intestinal tract,LAB can regulate the balance of human intestinal flora and improve host health.The purpose of this study was to isolate and screen LAB that are well suited to the intestinal characteristics of the Chinese population,with excellent probiotics and high antibacterial activity.After 16S ribosomal RNA(rRNA)homology and phylogenetic tree analysis,potential probiotics were tested for their antibacterial activity,resistance to artificial gastrointestinal fluid and drugs,surface hydrophobicity,and safety.Three strains of LAB with acid resistance,bile salt resistance,epithelial cell adhesion,and no multidrug resistance were selected:Lactobacillus salivarius,Leuconostoc lactis,and Lactobacillus paracasei.Analysis of the antibacterial active substances in the three strains and their fermentation broths revealed that the main antibacterial substances of L.lactis were organic acids,whereas those of L.salivarius and L.paracasei were organic acids and bacteriocins with broad-spectrum antibacterial activity.These three strains of probiotic LAB with high antibacterial activity were identified as bacterial resources that could potentially be used to develop probiotic preparations for the prevention and treatment of intestinal diseases caused by intestinal pathogens. | Zhijing LIU Cong XU Ran TIAN Wan WANG Jiage MA Liya GU Fei LIU Zhanmei JIANG Juncai HOU | 2021 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2021，22，7： | 10 |
| 3 | Visceral hypersensitive rats share common dysbiosis features with irritable bowel syndrome patients显示文摘AIM: To evaluate gut microbial dysbiosis in two visceral hypersensitive models in comparison with irritable bowel syndrome(IBS) patients and to explore the extent to which these models capture the dysbiosis of IBS patients. METHODS: Visceral hypersensitivity was developed using the maternal separation(MS) rat model and post-inflammatory rat model. The visceral sensitivity of the model groups and control group was evaluated using the abdominal withdraw reflex score and electromyography in response to graded colorectal distention. The 16 S ribosomal RNA gene from fecal samples was pyrosequenced and analyzed. The correlation between dysbiosis in the microbiota and visceral hypersensitivity was calculated. Positive findings were compared to sequencing data from a published human IBS cohort.RESULTS: Dysbiosis triggered by neonatal maternal separation was lasting but not static. Both MS and postinflammatory rat fecal microbiota deviated from that of the control rats to an extent that was larger than the co-housing effect. Two short chain fatty acid producing genera, Fusobacterium and Clostridium XI, were shared by the human IBS cohort and by the maternal separation rats and post-inflammatory rats, respectively, to different extents. Fusobacterium was significantly increased in the MS group, and its abundance positively correlated with the degree of visceral hypersensitivity. Porphyromonadaceae was a protective biomarker for both the rat control group and healthy human controls. CONCLUSION: The dysbiosis MS rat model and the post-inflammatory rat model captured some of the dysbiosis features of IBS patients. Fusobacterium, Clostridium XI and Porphyromonadaceae were identified as targets for future mechanistic research. | Xiao-Yan Zhou Ming Li Xia Li Xin Long Xiu-Li Zuo Xiao-Hua Hou Ying-Zi Cong Yan-Qing Li | 2016 | World Journal of Gastroenterology2016，22，22： | 10 |
| 4 | Special AT-rich sequence-binding protein 1 promotes cell growth and metastasis in colorectal cancer显示文摘AIM: To evaluate the expression of special AT-rich sequence-binding protein 1 (SATB1 ) gene in colorectal cancer and its role in colorectal cancer cell proliferation and invasion.METHODS: Immunohistochemistry was used to detect the protein expression of SATB1 in 30 colorectal cancer (CRC) tissue samples and pair-matched adjacent nontumor samples. Cell growth was investigated after enhancing expression of SATB1. Wound-healing assay and Transwell assay were used to investigate the impact of SATB1 on migratory and invasive abilities of SW480 cells in vitro . Nude mice that received subcutaneous implantation or lateral tail vein were used to study the effects of SATB1 on tumor growth or metastasis in vivo . RESULTS: SATB1 was over-expressed in CRC tissues and CRC cell lines. SATB1 promotes cell proliferation and cell cycle progression in CRC SW480 cells. SATB1 over-expression could promote cell growth in vivo . In addition, SATB1 could significantly raise the ability of cell migration and invasion in vitro and promote the ability of tumor metastasis in vivo . SATB1 could up-regulate matrix metalloproteases 2, 9, cyclin D1 and vimentin, meanwhile SATB1 could down-regulate E-cadherin in CRC. CONCLUSION: SATB1 acts as a potential growth and metastasis promoter in CRC. SATB1 may be useful as a therapeutic target for CRC. | Xue-Feng Fang Zhi-Bo Hou Xin-Zheng Dai Cong Chen Jing Ge Hong Shen Xiao-Feng Li Li-Ke Yu Ying Yuan | 2013 | World Journal of Gastroenterology2013，19，15： | 9 |
| 5 | Mutation analysis of PAX6 gene in a large Chinese family with aniridia显示文摘Background Mutations in PAX6 gene have been shown to be the genetic cause of aniridia, which is a severe panocular eye disease characterised by iris hypoplasia. However, there is no study to do genetic analysis of aniridia, although there are several case reports in China. Here, we describe a mutation analysis of PAX6 in a large Chinese family with aniridia. Methods Genomic DNA from venous blood samples was prepared. Haplotype analysis was performed with two genetic markers (D11S904 and D11S935). Fourteen exons of the PAX6 gene were amplified from genomic DNA. Polymerase chain reaction (PCR) products of each exon were analysed by single strand conformational polymorphism (SSCP). The PCR products having an abnormal pattern were sequenced to confirm the mutation.Results Significant evidence for allele sharing in affected patients was detected suggesting that PAX6 mutation links to aniridia in this family. An extra band corresponding to exon 9 in PAX6 was found by single strand conformational polymorphism analysis in all the aniridia patients in this family, but not detected in the unaffected members. A mutation of C to T was detected by sequencing at the nucleotide 1080 that converts the Arg codon (CGA) to the termination codon (TGA).Conclusions Aniridia is caused by a nonsense mutation of PAX6 gene in the large Chinese kindred. Genetic test is important to prevent the transmission of aniridia to their offsprings in the kindred by prenatal diagnosis. | SONG Shu-juan LIU Ying-zhi CONG Ri-chang JIN Ying HOU Zhi-qiang MA Zhi-zhong REN Guo-cheng LI Ling-song | 2005 | Chinese Medical Journal2005，，4： | 7 |
| 6 | 3-year Treatment of Tenofovir Alafenamide vs.Tenofovir Disoproxil Fumarate for Chronic HBV Infection in China显示文摘Background and Aims:Tenofovir alafenamide(TAF)has similar efficacy to tenofovir disoproxil fumarate(TDF)but with improved renal and bone safety in chronic hepatitis B patients studied outside of China.We report 3-year results from two phase 3 studies with TAF in China(Clinicaltrials.gov:NCT02836249 and NCT02836236).Methods:Chinese hepatitis B e antigen(HBeAg)-positive and-negative chronic hepatitis B patients with viremia and elevated alanine aminotransferase were randomized 2:1 to TAF or TDF treatment groups and treated in a double-blind fashion for 144 weeks(3 years).Efficacy responses were assessed by individual study while safety was assessed by a pooled analysis.Results:Of the 334 patients(180 HBeAg-positive and 154 HBeAg-negative)randomized and treated,baseline characteristics were similar between groups.The overall mean age was 38 years and 73%were male.The mean HBV DNA was 6.4 log10 IU/mL.The median alanine aminotransferase was 88 U/L,and 37%had a history of antiviral use.At week 144,the proportion with HBV DNA<29 IU/mL was similar among the two groups,with TAF at 83%vs.TDF at 79%,and TAF at 93%vs.TDF at 92%for the HBeAg-positive and-negative patients,respectively.In each study,higher proportions of TAF than TDF patients showed normalized alanine aminotransferase(via the American Association for the Study of Liver Diseases and the China criteria)and showed loss of HBsAg;meanwhile,the HBeAg seroconversion rates were similar.Treatment was well-tolerated among the TAF patients,who showed a smaller median decline in creatinine clearance(−0.4 vs.−3.2 mL/min;p=0.014)and less percentage change in bone mineral density vs.TDF at hip(−0.95%vs.−1.93%)and spine(+0.35%vs.−1.40%).Conclusions:In chronic hepatitis B patients from China,TAF treatment provided efficacy similar to TDF but with better renal and bone safety at 3 years. | Jinlin Hou Qin Ning Zhongping Duan You Chen Qing Xie Fu-Sheng Wang Lunli Zhang Shanming Wu Hong Tang Jun Li Feng Lin Yongfeng Yang Guozhong Gong John FFlaherty Anuj Gaggar Shuyuan Mo Cong Cheng Gregory Camus Chengwei Chen Yan Huang Jidong Jia Mingxiang Zhang GS-US-320-0110 and GS-US-320-0108 China Investigators | 2021 | Journal of Clinical and Translational Hepatology2021，9，3： | 7 |
| 7 | Fabrication of hollow porous PLGA microspheres for controlled protein release and promotion of cell compatibility显示文摘This letter reports on the fabrication of hollow,porous and non-porous poly(D,L-lactide-co-glycolide) (PLGA) microspheres(MSs) for the controlled release of protein and promotion of cell compatibility of tough hydrogels.PLGA MSs with different structures were prepared with modified double emulsion methods,using bovine serum albumin(BSA) as a porogen during emulsification.The release of the residual BSA from PLGA MSs was investigated as a function of the MS structure.The hollow PLGA MSs show a faster protein release than the porous MSs,while the non-porous MSs have the slowest protein release.Compositing the PLGA MSs with poly(vinyl alcohol)(PVA) hydrogels promoted chondrocyte adhesion and proliferation on the hydrogels. | Guo-Hua Zhang Rui-Xia Hou Dan-Xia Zhan Yang Cong Ya-Jun Cheng Jun Fu | 2013 | Chinese Chemical Letters2013，24，8： | 7 |

| 9 | Elemental composition in surface snow from the ultra-high elevation area of Mt. Qomolangma (Everest)显示文摘A total of 14 surface snow (0―10 cm) samples were collected along the climbing route (6500―8844 m a.s.l.) on the northern slope of Mt. Qomolangma in May, 2005. Analysis of elemental concentrations in these samples showed that there are no clear trends for element variations with elevation due to re- distribution of surface snow by strong winds during spring. In addition, local crustal aerosol inputs also have an influence on elemental composition of surface snow. Comparison between elemental concentration datasets of 2005 and 1997 indicated that data from 2005 were of higher quality. Elemental concentrations (especially for heavy metals) at Mt. Qomolangma are comparable with polar sites, and far lower than large cities. This indicates that anthropogenic activities and heavy metal pollution have little effect on the Mt. Qomolangma atmospheric environment, which can be representative of the background atmospheric environment. | ZHANG QiangGong KANG ShiChang CONG ZhiYuan HOU ShuGui LIU YongQin | 2008 | Chinese Science Bulletin2008，53，2： | 5 |
| 10 | Xiaoyaosan improves depressive-like behaviors by regulating the NLRP3 signaling pathway in the rat cerebral cortex显示文摘Objective:To observe changes in the molecular expression of the NLR Family Pyrin Domain Containing Protein 3(NLRP3)pathway in depressed rats after treatment with Xiaoyaosan,and identify the regulatory mechanism of this compound.Methods:Male SpragueeD awley rats were randomly divided into five groups with 12 rats in each group,including the control group,model group,Fluoxetine group,Xiaoyaosan group,and MCC950 group.A depression model was generated by chronic immobilization stress(induced by 3 h of restraint immobilization every day),and the drugs were administered at the same time in each group for 21 days.The effects of Xiaoyaosan on behavioral changes of depressed rats were observed through macroscopic characterization,body mass,open field experiments,and a sucrose preference test.The m RNA and protein expression of the NLRP3 signaling pathway was examined by fluorescence real-time quantitative PCR and Western blot assays.Results:The Xiaoyaosan group,Fluoxetine group,and MCC950 group rats showed improved depressive behavior and an increased weight of sucrose water consumption.The protein and mRNA expression levels of NLRP3,Caspase-1,and IL-1 b were also decreased in the Fluoxetine,Xiaoyaosan,and MCC950 groups.Conclusion:NLRP3,Caspase-1,and IL-1 b protein and mRNA expression levels were increased in the cortex of depressed rats,while Xiaoyaosan protected cortical tissue in these rats by decreasing NLRP3,Caspase-1,and IL-1 b protein and mRNA expression. | Cong Chen Rong Yu Zhe Xue Zhiyi Yan Qinlai Bian Yajing Hou Yunzhi Chen Yueyun Liu Jiaxu Chen | 2020 | Journal of Traditional Chinese Medical Sciences2020，7，3： | 5 |
| 11 | Metformin activates chaperone-mediated autophagy and improves disease pathologies in an Alzheimer disease mouse model显示文摘Chaperone-mediated autophagy(CMA)is a lysosome-dependent selective degradation pathway implicated in the pathogenesis of cancer and neurodegenerative diseases.However,the mechanisms that regulate CMA are not fully understood.Here,using unbiased drug screening approaches,we discover Metformin,a drug that is commonly the first medication prescribed for type 2 diabetes,can induce CMA.We delineate the mechanism of CMA induction by Metformin to be via activation of TAK1-IKKα/β signaling that leads to phosphorylation of Ser85 of the key mediator of CMA,Hsc70,and its activation.Notably,we find that amyloid-beta precursor protein(APP)is a CMA substrate and that it binds to Hsc70 in an IKKα/β-dependent manner.The inhibition of CMA-mediated degradation of APP enhances its cytotoxicity.Importantly,we find that in the APP/PS1 mouse model of Alzheimer's disease(AD),activation of CMA by Hsc70 overexpression or Metformin potently reduces the accumulated brain Aβplaque levels and reverses the molecular and behavioral AD phenotypes.Our study elucidates a novel mechanism of CMA regulation via Metformin-TAK1-IKKα/β-Hsc70 signaling and suggests Metformin as a new activator of CMA for diseases,such as AD,where such therapeutic intervention could be beneficial. | Xiaoyan Xu Yaqin Sun Xufeng Cen Bing Shan Qingwei Zhao Tingxue Xie Zhe Wang Tingjun Hou Yu Xue Mengmeng Zhang Di Peng Qiming Sun Cong Yi Ayaz Najafov Hongguang Xia | 2021 | Protein & Cell2021，12，10： | 5 |
| 12 | Morphology and composition of particles emitted from a port fuel injection gasoline vehicle under real-world driving test cycles显示文摘Traffic vehicles, many of which are powered by port fuel injection(PFI) engines, are major sources of particulate matter in the urban atmosphere. We studied particles from the emission of a commercial PFI-engine vehicle when it was running under the states of cold start, hot start, hot stabilized running, idle and acceleration, using a transmission electron microscope and an energy-dispersive X-ray detector. Results showed that the particles were mainly composed of organic, soot, and Ca-rich particles, with a small amount of S-rich and metal-containing particles, and displayed a unimodal size distribution with the peak at 600 nm. The emissions were highest under the cold start running state, followed by the hot start, hot stabilized, acceleration, and idle running states. Organic particles under the hot start and hot stabilized running states were higher than those of other running states. Soot particles were highest under the cold start running state. Under the idle running state, the relative number fraction of Ca-rich particles was high although their absolute number was low. These results indicate that PFI-engine vehicles emit substantial primary particles,which favor the formation of secondary aerosols via providing reaction sites and reaction catalysts, as well as supplying soot, organic, mineral and metal particles in the size range of the accumulation mode. In addition, the contents of Ca, P, and Zn in organic particles may serve as fingerprints for source apportionment of particles from PFI-engine vehicles. | Jiaoping Xing Longyi Shao Wenbin Zhang Jianfei Peng Wenhua Wang Cong Hou Shijin Shuai Min Hu Daizhou Zhang | 2019 | Journal of Environmental Sciences2019，31，2： | 4 |

| 14 | Endoplasmic reticulum stress contributed to β1-adrenoceptor autoantibody-induced reduction of autophagy in cardiomyocytes显示文摘Autophagy reduction has been confirm ed as an im portant mechanism in apoptosis induction.Our previous study showed that decreased autophagy induced by Pi-adrenoceptor autoantibodies(Pi-AAs)enhanced cardiom yocyte apoptosis and contributed to heart failure progression.Endoplasmic reticulum stress(ERS)is known to be an im portant mechanism in intracellular homeostasis and is closely related to autophagy.However,ERS in pi-AA-induced autophagy dysfunction of cardiom yocytes remains unclear.In this study,we used an active im m unization rat model and H9c2 cardiom yocytes to study the role of ERS in Pi-AA-induced autophagy.Results showed that prolonged action of Pi-AAs significantly reduced the autophagy of myocardial tissues and H9c2 cardiom yocytes,and ERS and its related apoptotic pathways were significantly activated.Moreover,mRFP-GFP-LC3 double-labeled adenoviruses were used to detect cardiom yocyte autophagic flux to confirm that Pi-AAs caused a significant decrease in autophagic flux in H9c2 cardiom yocytes.The ERS inhibitor,4-phenylbutyrate(4-PBA),partially attenuated the β1-AA-induced reduction of cardiom yocyte autophagy,consistent w ith the effect of the m am m alian target of rapam ycin inh ibito r rapamycin(Rapa).Compared to the pretreatm ent with 4-PBA or Rapa alone,pretreatm ent w ith the com bination of 4-PBA and Rapa had a greater effect on attenuating the pi-AA-induced decrease in autophagy and Pi-AA-induced apoptosis in cardiomyocytes.This study provides an experim ental basis fo r the role of Pi-AAs in the homeostatic maintenance of cardiom yocytes in patients w ith heart failure w ith respect to autophagy and ERS. | Li Wang Na Ning Changtu Wang Xiaohong Hou Yuan Yuan Yanan Ren Cong Sun Zi Yan Xiaohui Wang Huirong Liu | 2019 | Acta Biochimica et Biophysica Sinica2019，51，10： | 3 |

| 16 | Longitudinal Compression Behavior of Functionally Graded Ti–6Al–4V Meshes显示文摘The compressive deformation behavior in the longitudinal direction of graded Ti–6Al–4V meshes fabricated by electron beam melting was investigated using experiments and finite element methods(FEM).The results indicate that the overall strain along the longitudinal direction is the sum of the net strain carried by each uniform mesh constituent and the deformation behavior fits the Reuss model well. The layer thickness and the sectional area have no effect on the elastic modulus, whereas the strength increases with the sectional area due to the edge effect of each uniform mesh constituent. By optimizing3 D graded/gradient design, meshes with balanced superior properties, such as high strength, energy absorption and low elastic modulus, can be fabricated by electron beam melting. | Shangzhou Zhang Cong Li Wentao Hou Shuo Zhao Shujun Li | 2016 | Journal of Materials Science & Technology2016，32，11： | 3 |

| 18 | Ultrahigh rate capability of 1D/2D polyaniline/titanium carbide(MXene)nanohybrid for advanced asymmetric supercapacitors显示文摘High energy density and enhanced rate capability are highly sought-after for supercapacitors in today's mobile world.In this work,polyaniline/titanium carbide(MXene)(PANI/Ti3C2Tx)nanohybrid is synthesized through a facile and cost-effective self-assembly of.one-dimensional(10)PANI nanofibers and two-dimensional(20)Ti3C2Tx nanosheets.PANl!Ti3C2Tx delivers greatly improved specific capacitance,ultrahigh rate capability(67%capacitance retention from 1 to 100 A·g^(-1))as well as good cycle stability.Electrochemical kinetic analysis reveals that PANI/Ti3C2Tx is featured with surface capacitance-dominated process and has a quasi-reversible kinetics at high scan rates,giving rise to an ultrahigh rate capability.By using PANl!Ti3C2Tx as positive electrode,an 1.8 V aqueous asymmetric supercapacitor(ASC)is successfully assembled,showing a maximum energy density of 50.8 Wh·kg^(-1)·(at 0.9 kW-kg-1)and a power density of 18 kW·kg^(-1)(at 26 Wh·kg^(-1)).Moreover,an 3.0 V organic ASC is also elaborately fabricated,·by using PANI/Ti3C2Tx,achieving an ultrahigh energy density of 67.2 Wh·kg^(-1)(at 1.5 kW·kg^(-1))and a power density of 30 kW·kg^(-1)·(at 26.8 Wh·kg^(-1)).The present work not only improves fundamental understanding of the structure-property relationship towards ultrahigh rate capability electrode materials,but also provides valuable guideline for the rational design of high-performance:energy storage devices with both high energy and power densities. | Jinhua Zhou Qi Kang Shuchi Xu Xiaoge Li Cong Liu Lu Ni Ningna Chen Chunliang Lu Xizhang Wang Luming Peng Xuefeng Guo Weiping Ding Wenhua Hou | 2022 | Nano Research2022，15，1： | 2 |
| 19 | Sterilization and disinfection methods for decellularized matrix materials:Review,consideration and proposal显示文摘Sterilization is the process of killing all microorganisms,while disinfection is the process of killing or removing all kinds of pathogenic microorganisms except bacterial spores.Biomaterials involved in cell experiments,animal experiments,and clinical applications need to be in the aseptic state,but their physical and chemical properties as well as biological activities can be affected by sterilization or disinfection.Decellularized matrix(dECM)is the low immunogenicity material obtained by removing cells from tissues,which retains many inherent components in tissues such as proteins and proteoglycans.But there are few studies concerning the effects of sterilization or disinfection on dECM,and the systematic introduction of sterilization or disinfection for dECM is even less.Therefore,this review systematically introduces and analyzes the mechanism,advantages,disadvantages,and applications of various sterilization and disinfection methods,discusses the factors influencing the selection of sterilization and disinfection methods,summarizes the sterilization and disinfection methods for various common dECM,and finally proposes a graphical route for selecting an appropriate sterilization or disinfection method for dECM and a technical route for validating the selected method,so as to provide the reference and basis for choosing more appropriate sterilization or disinfection methods of various dECM. | Meihan Tao Tianrang Ao Xiaoyan Mao Xinzhu Yan Rabia Javed Weijian Hou Yang Wang Cong Sun Shuang Lin Tianhao Yu Qiang Ao | 2021 | Bioactive Materials2021，6，9： | 2 |
| 20 | Model of decentralized cross-chain energy trading for power systems显示文摘With the development of the energy Internet, more distributed generators are connected to the power grid, resulting in numerous heterogeneous energy networks. However, different energy networks cannot perform efficient energy trading in the centralized management mode, this deeply affecting the complementary ability of heterogeneous energy, resulting in the islanded energy phenomenon. In this model, the same energy on the chain is traded within the chain, and the heterogeneous energy on different chains is traded across chains. To trade energy between heterogeneous energy networks more efficiently, the blockchain-based cross-chain model is proposed based on the existing infrastructure. Heterogeneous energy nodes are assigned to different energy sub-chains and cross-chain energy transactions are performed through a relay-chain, which utilizes the improved Boneh–Lynn–Shacham signature scheme consensus algorithm based on the proof-of-stake and practical Byzantine fault tolerance. The experimental simulations on energy trading efficiency, throughput, and security, show its superiority over existing systems. Further, the simulation results provide a reference for the application of cross-chain technology in energy interconnection. | Shaomin Zhang Cong Hou | 2021 | Global Energy Interconnection2021，4，3： | 2 |
