| 1 | A Collinearity-Incorporating Homology Inference Strategy for Connecting Emerging Assemblies in the Triticeae Tribe as a Pilot Practice in the Plant Pangenomic Era显示文摘Plant genome sequencing has dramatically increased,and some species even have multiple high-quality reference versions.Demands for clade-specific homology inference and analysis have increased in the pangenomic era.Here we present a novel method,GeneTribe(http://gffzz6c7fcf032cb94ff5sfwno0ffpp6on6ofk.ffgz.tsg.suse.edu.cn/genetribe/),for homology inference among genetically similar genomes that incorporates gene collinearity and shows bet-ter performance than traditional sequence-similarity-based methods in terms of accuracy and scalability.The Triticeae tribe is a typical allopolyploid-rich clade with complex species relationships that includes many important crops,such as wheat,barley,and rye.We built Triticeae-GeneTribe(http://gffzzaeec8df70e7c4b21hfwno0ffpp6on6ofk.ffgz.tsg.suse.edu.cn/TGT/),a homology database,by integrating 12 Triticeae genomes and 3 outgroup model genomes and implemented versatile analysis and visualization functions.With macrocollinearity analysis,we were able to construct a refined model illustrating the structural rearrangements of the 4A-5A-7B chromosomes in wheat as two major translocation events.With collinearity analysis at both the macro-and microscale,we illustrated the complex evolutionary history of homologs of the wheat vernalization gene Vm2,which evolved as a combined result of genome translocation,duplication,and polyploidization and gene loss events.Our work provides a useful practice for connecting emerging genome assemblies,with awareness of the extensive polyploidy in plants,and will help researchers efficiently exploit genome sequence re-sources. | Yongming Chen Wanjun Song Xiaoming Xie Zihao Wang Panfeng Guan Huiru Peng Yuannian Jiao Zhongfu Ni Qixin Sun Weilong Guo | 2020 | Molecular Plant2020，13，12： | 14 |
| 2 | FISS GAN:A Generative Adversarial Network for Foggy Image Semantic Segmentation显示文摘Because pixel values of foggy images are irregularly higher than those of images captured in normal weather(clear images),it is difficult to extract and express their texture.No method has previously been developed to directly explore the relationship between foggy images and semantic segmentation images.We investigated this relationship and propose a generative adversarial network(GAN)for foggy image semantic segmentation(FISS GAN),which contains two parts:an edge GAN and a semantic segmentation GAN.The edge GAN is designed to generate edge information from foggy images to provide auxiliary information to the semantic segmentation GAN.The semantic segmentation GAN is designed to extract and express the texture of foggy images and generate semantic segmentation images.Experiments on foggy cityscapes datasets and foggy driving datasets indicated that FISS GAN achieved state-of-the-art performance. | Kunhua Liu Zihao Ye Hongyan Guo Dongpu Cao Long Chen Fei-Yue Wang | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，8： | 7 |
| 3 | Carbon confinement synthesis of interlayer-expanded and sulfur-enriched MoS2+x nanocoating on hollow carbon spheres for advanced Li-S batteries显示文摘High energy density and low-cost lithium-sulfur batteries have been considered as one of the most promising candidates for next-generation energy storage systems.However,the intrinsic problems of the sulfur cathode severely restrict their further practical application.Here,a unique double-shell architecture composed of hollow carbon spheres@interlayer-expanded and sulfur-enriched MoS2+x nanocoating composite has been developed as an efficient sulfur host.A uniform precursor coating derived from heteropolyanions-induced polymerization of pyrrole leads to space confinement effect during the in-situ sulfurization process,which generates the interlayer-expanded and sulfur-enriched MoS2+x nanosheets on amorphous carbon hollow spheres.This new sulfur host possesses multifarious merits including sufficient voids for loading sulfur active materials,high electronic conductivity,and fast lithium-ion diffusive pathways.In addition,additional active edge sites of MoS2+x accompanied by the nitrogen-doped carbon species endow the sulfur host with immobilizing and catalyzing effects on the soluble polysulfide species,dramatically accelerating their conversion kinetics and re-utilization.The detailed defect-induced interface catalytic reaction mechanism is firstly proposed.As expected,the delicately-designed sulfur host exhibits an outstanding initial discharge capacity of 1,249 mAh·g^−1 at 0.2 C and a desirable rate performance(593 mAh·g^−1 at 5.0 C),implying its great prospects in achieving superior electrochemical performances for advanced lithium sulfur batteries. | Wenda Li Dezhu Wang Zihao Song Zhijiang Gong Xiaosong Guo Jing Liu Zhonghua Zhang Guicun Li | 2019 | Nano Research2019，12，11： | 6 |
| 4 | Ectopic expression of VRT-A2 underlies the origin of Triticum polonicum and Triticum petropavlovskyi with long outer glumes and grains显示文摘Polish wheat (Triticum polonicum) is a unique tetraploid wheat species characterized by an elongated outer glume. The genetic control of the long-glume trait by a single semi-dominant locus, P1 (from Polish wheat), was established more than 100 years ago, but the underlying causal gene and molecular nature remain elusive. Here, we report the isolation of VRT-A2, encoding an SVP-clade MADS-box transcription factor, as the P1 candidate gene. Genetic evidence suggests that in T. polonicum, a naturally occurring sequence rearrangement in the intron-1 region of VRT-A2 leads to ectopic expression of VRT-A2 in floral organs where the long-glume phenotype appears. Interestingly, we found that the intron-1 region is a key ON/OFF molecular switch for VRT-A2 expression, not only because it recruits transcriptional repressors, but also because it confers intron-mediated transcriptional enhancement. Genotypic analyses using wheat accessions indicated that the P1 locus is likely derived from a single natural mutation in tetraploid wheat, which was subsequently inherited by hexaploid T. petropavlovskyi. Taken together, our findings highlight the promoter-proximal intron variation as a molecular basis for phenotypic differentiation, and thus species formation in Triticum plants. | Jing Liu Zhaoyan Chen Zhihui Wang Zhaoheng Zhang Xiaoming Xie Zihao Wang Lingling Chai Long Song Xuejiao Cheng Man Feng Xiaobo Wang Yanhong Liu Zhaorong Hu Jiewen Xing Zhenqi Su Huiru Peng Mingming Xin Yingyin Yao Weilong Guo Qixin Sun Jie Liu Zhongfu Ni | 2021 | Molecular Plant2021，14，9： | 4 |

Bacterial genome DNA of separated L. acidophilus in fermented sample was taken as template,and L. acidophilus in fermented material was conducted the quantitative determination by real-time quantitative PCR( RT-PCR). Analysis on RT-PCR results shown that contents of L. acidophilus in the test sample reached 1. 5 billion CFU / g. Test results shown that contents of L. acidophilus in fermented material could be detected accurately by the established RT-PCR method in the test,indicating that the established RT-PCR method could be applied to the detection of L. acidophilus in fermented material. | Guo Zihao Fang Hua Xia Zhisheng Zhu Xiaoshi Sun Zhongchao Yu Hanli Xia Jiaji | 2016 | Animal Husbandry and Feed Science2016，8，1： | 4 |
| 6 | Design of the real-time detection system based on LabVIEW for no-till seeder working performance显示文摘In order to ensure the working performance of the seeder,reduce the labor intensity of manual testing,and improve the efficiency and accuracy of the detection,a real-time detection system for detecting the performance of no-till seeders was designed based on the LabVIEW software platform of virtual instrument technology and the MCC USB-231 data acquisition card.The detection system can be used to detect the seeding quality index and residue cover index.The detection of the seeding quality index included the middle detection between the metering device and the opener,the end detection between the opener and the furrow.The result of the field test showed that the detection accuracies of seed quantity,multiple index,and miss index were 94.51%,92.83%,and 91.81%,respectively.The fault position can be accurately determined,and the measurement accuracy of residue cover index was 94.54%.The working performance of the no-tillage seeder can be monitored by the detection system to avoid the occurrence of reseeding and miss-seeding and improve production efficiency. | Huibin Zhu Cheng Qian Zihao Guo Lizhen Bai | 2021 | International Journal of Agricultural and Biological Engineering2021，14，5： | 3 |

| 8 | A wheat integrative regulatory network from large-scale complementary functional datasets enables trait-associated gene discovery for crop improvement显示文摘Gene regulation is central to all aspects of organism growth,and understanding it using large-scale functional datasets can provide a whole view of biological processes controlling complex phenotypic traits in crops.However,the connection between massive functional datasets and trait-associated gene discovery for crop improvement is still lacking.In this study,we constructed a wheat integrative gene regulatory network(wGRN)by combining an updated genome annotation and diverse complementary functional datasets,including gene expression,sequence motif,transcription factor(TF)binding,chromatin accessibility,and evolutionarily conserved regulation.wGRN contains 7.2 million genome-wide interactions covering 5947 TFs and 127439 target genes,which were further verified using known regulatory relationships,condition-specific expression,gene functional information,and experiments.We used wGRN to assign genome-wide genes to 3891 specific biological pathways and accurately prioritize candidate genes associated with complex phenotypic traits in genome-wide association studies.In addition,wGRN was used to enhance the interpretation of a spike temporal transcriptome dataset to construct high-resolution networks.We further unveiled novel regulators that enhance the power of spike phenotypic trait prediction using machine learning and contribute to the spike phenotypic differences among modern wheat accessions.Finally,we developed an interactive webserver,wGRN(http://gffzzaeec8df70e7c4b21hfwno0ffpp6on6ofk.ffgz.tsg.suse.edu.cn/wGRN),for the community to explore gene regulation and discover trait-associated genes.Collectively,this community resource establishes the foundation for using large-scale functional datasets to guide trait-associated gene discovery for crop improvement. | Yongming Chen Yiwen Guo Panfeng Guan Yongfa Wang Xiaobo Wang Zihao Wang Zhen Qin Shengwei Ma Mingming Xin Zhaorong Hu Yingyin Yao Zhongfu Ni Qixin Sun Weilong Guo Huiru Peng | 2023 | Molecular Plant2023，16，2： | 1 |
| 9 | The Solar Upper Transition Region Imager(SUTRI)Onboard the SATech-01 Satellite显示文摘The Solar Upper Transition Region Imager(SUTRI)onboard the Space Advanced Technology demonstration satellite(SATech-01),which was launched to a Sun-synchronous orbit at a height of~500 km in 2022 July,aims to test the on-orbit performance of our newly developed Sc/Si multi-layer reflecting mirror and the 2k×2k EUV CMOS imaging camera and to take full-disk solar images at the Ne VII 46.5 nm spectral line with a filter width of~3 nm.SUTRI employs a Ritchey-Chrétien optical system with an aperture of 18 cm.The on-orbit observations show that SUTRI images have a field of view of~416×416 and a moderate spatial resolution of~8″without an image stabilization system.The normal cadence of SUTRI images is 30 s and the solar observation time is about16 hr each day because the earth eclipse time accounts for about 1/3 of SATech-01's orbit period.Approximately15 GB data is acquired each day and made available online after processing.SUTRI images are valuable as the Ne VII 46.5 nm line is formed at a temperature regime of~0.5 MK in the solar atmosphere,which has rarely been sampled by existing solar imagers.SUTRI observations will establish connections between structures in the lower solar atmosphere and corona,and advance our understanding of various types of solar activity such as flares,filament eruptions,coronal jets and coronal mass ejections. | Xianyong Bai Hui Tian Yuanyong Deng Zhanshan Wang Jianfeng Yang Xiaofeng Zhang Yonghe Zhang Runze Qi Nange Wang Yang Gao Jun Yu Chunling He Zhengxiang Shen Lun Shen Song Guo Zhenyong Hou Kaifan Ji Xingzi Bi Wei Duan Xiao Yang Jiaben Lin Ziyao Hu Qian Song Zihao Yang Yajie Chen Weidong Qiao Wei Ge Fu Li Lei Jin Jiawei He Xiaobo Chen Xiaocheng Zhu Junwang He Qi Shi Liu Liu Jinsong Li Dongxiao Xu Rui Liu Taijie Li Zhenggong Feng Yamin Wang Chengcheng Fan Shuo Liu Sifan Guo Zheng Sun Yuchuan Wu Haiyu Li Qi Yang Yuyang Ye Weichen Gu Jiali Wu Zhe Zhang Yue Yu Zeyi Ye Pengfeng Sheng Yifan Wang Wenbin Li Qiushi Huang Zhong Zhang | 2023 | Research in Astronomy and Astrophysics2023，23，6： | 1 |
| 10 | TaMADS29 interacts with TaNF-YB1 to synergistically regulate early grain development in bread wheat显示文摘Grain development is a crucial determinant of yield and quality in bread wheat(Triticum aestivum L.).However,the regulatory mechanisms underlying wheat grain development remain elusive.Here we report how Ta MADS29 interacts with Ta NF-YB1 to synergistically regulate early grain development in bread wheat.The tamads29 mutants generated by CRISPR/Cas9 exhibited severe grain filling deficiency,coupled with excessive accumulation of reactive oxygen species(ROS)and abnormal programmed cell death that occurred in early developing grains,while overexpression of Ta MADS29 increased grain width and1,000-kernel weight.Further analysis revealed that Ta MADS29 interacted directly with Ta NF-YB1;null mutation in Ta NF-YB1caused grain developmental deficiency similar to tamads29 mutants.The regulatory complex composed of Ta MADS29 and Ta NF-YB1 exercises its possible function that inhibits the excessive accumulation of ROS by regulating the genes involved in chloroplast development and photosynthesis in early developing wheat grains and prevents nucellar projection degradation and endosperm cell death,facilitating transportation of nutrients into the endosperm and wholly filling of developing grains.Collectively,our work not only discloses the molecular mechanism of MADS-box and NF-Y TFs in facilitating bread wheat grain development,but also indicates that caryopsis chloroplast might be a central regulator of grain development rather than merely a photosynthesis organelle.More importantly,our work offers an innovative way to breed high-yield wheat cultivars by controlling the ROS level in developing grains. | Guoyu Liu Runqi Zhang Sen Li Rehmat Ullah Fengping Yang Zihao Wang Weilong Guo Mingshan You Baoyun Li Chaojie Xie Liangsheng Wang Jie Liu Zhongfu Ni Qixin Sun Rongqi Liang | 2023 | Science China(Life Sciences)2023，66，7： | 1 |

| 12 | Forward modeling and inversion of the relation model between the gas content of plume and its seismic attribute显示文摘The methane bubble plume attracts interest because it offers direct evidence of seafloor gas leakage and plays an indirect role in the exploration and identification of natural gas hydrate.In this study,based on established plume models and their migration sections,three amplitude-class attributes were extracted from three formations for the migration sections of five plumes,and the correlation between the gas content and seismic attribute was obtained.As the gas content increases,the amplitude attribute correspondingly increases,and the linear correlation is relatively good.Moreover,correlation coefficients between gas content and amplitude attributes are close to 1.0.By using linear fitting,the relation model between the gas content of the plume and the seismic attribute was obtained.The relation model was subsequently used to invert the gas content from a real databearing plume.Comparison of the gas content section of the plume with the attribute section and real seismic section reveals common distribution characteristics,namely,the color of the section in the lower right corner is dark.If the amplitude value is large in the seismic section of the real plume,the amplitude attribute value is also large in the corresponding attribute section,and the inverted value of the gas content is also large(because gas content and amplitude are linearly correlated),which indicates that the plume bubbles of the section in the lower right corner is intensively distributed.Finally,the obtained gas content section of the plume can reflect the distribution of the plume bubble content more simply and intuitively,from which the distribution law of seafloor bubbles can be deduced,and this lays a foundation for the further estimation of the gas content of the plume and hydrate reserves. | Canping Li Jiachun You Yanchun Tan Fengying Chen Yilin Liu Zihao Guo Xinyu Tian | 2021 | Acta Oceanologica Sinica2021，40，5： | 1 |
| 13 | Skin layer of A380 aluminium alloy die castings and its blistering during solution treatment显示文摘Skin layer is a characteristic microstructure of aluminium die castings, which would effect the surface blistering during solution treatment. In this study, the microstructures of skin layer were investigated by the methods of optical microscope (OM), scanning electron microscope (SEM) and electron probe microanalyzer (EPMA). High resolution X-ray CT was used to compare the skin layer with normal surface before and after solution treatment. With the aid of computational fluid dynamics (CFD), the formation mechanism of the skin layer was discussed based on microstructure distribution, solute segregation, porosity distribution and surface blistering. The results suggested that the skin layer is related to a succession of complex processes before the filling process finished. Pore clusters or laminar defects would be formed in skin layers during solution treatm ent and cause severe surface blistering. | Zihao Yuan Zhipeng Guo S.M.Xionga | 2019 | Journal of Materials Science & Technology2019，35，9： | 1 |
| 14 | Hierarchical Task Planning for Power Line Flow Regulation显示文摘The complexity and uncertainty in power systems cause great challenges to controlling power grids.As a popular data-driven technique,deep reinforcement learning(DRL)attracts attention in the control of power grids.However,DRL has some inherent drawbacks in terms of data efficiency and explainability.This paper presents a novel hierarchical task planning(HTP)approach,bridging planning and DRL,to the task of power line flow regulation.First,we introduce a threelevel task hierarchy to model the task and model the sequence of task units on each level as a task planning-Markov decision processes(TP-MDPs).Second,we model the task as a sequential decision-making problem and introduce a higher planner and a lower planner in HTP to handle different levels of task units.In addition,we introduce a two-layer knowledge graph that can update dynamically during the planning procedure to assist HTP.Experimental results conducted on the IEEE 118-bus and IEEE 300-bus systems demonstrate our HTP approach outperforms proximal policy optimization,a state-of-the-art deep reinforcement learning(DRL)approach,improving efficiency by 26.16%and 6.86%on both systems. | Chenxi Wang Youtian Du Yanhao Huang Yuanlin Chang Zihao Guo | 2024 | CSEE Journal of Power and Energy Systems2024，10，1： | 0 |
| 15 | Degradation of platinum electrocatalysts for methanol oxidation by lead contamination显示文摘Platinum exhibits high electrocatalytic activity toward various reactions but might be poisoned by some species. This communication reports a new finding that the electrocatalytic activity of platinum for methanol oxidation will be largely lost in a lead-contaminated environment. This activity loss is demonstrated in an electrochemical cell using a lead counter electrode for measuring the activity of platinum electrode towards methanol oxidation. The recorded methanol oxidation current in this cell is significantly decreased compared with that using a platinum counter electrode. The possible mechanism is related to the adsorption of trace lead ions from the lead counter electrode, as confirmed by comparing the calculated binding energies of platinum and lead ions with oxygen ion. This report is of great importance for reliably designing and efficiently managing direct methanol fuel cells, because trace lead might be present in various components in the fuel cell systems or in air and attention should be paid to its negative effect. | Zihao Li Xianggui Zhou Subhash Singh Xiaoming Wei Chunlei Guo Weishan Li | 2023 | Chinese Chemical Letters2023，34，2： | 0 |
| 16 | Community Authenticity Experience of Shared Accommodation Consumers显示文摘By constructing a research framework of theoretical concepts such as leisure involvement, authenticity experience, place attachment, and willingness to revisit, the aim is to explore the authenticity experience and its influencing mechanisms in shared accommodation consumption. Research data are collected by using questionnaire survey method, and statistical analysis of data is conducted using SPSS 21.0. Research has found that leisure involvement has a significant positive impact on authenticity experience, place attachment, and willingness to revisit;authenticity experience has a significant positive impact on place attachment and willingness to revisit;place attachment has a significant positive impact on willingness to revisit. Therefore, shared accommodation owners need to strengthen the editing and publishing of leisure strategies on we media to enhance customers sense of leisure involvement;pay attention to enhancing the local authentic cultural experience of tenants, in order to increase their sense of attachment to the place and thereby enhance their willingness to stay. | Haiming CHEN Mengting DENG Yiyu CHEN Xuejuan KONG Shaoling GUO Jiaxin SHEN Zihao LIN | 2023 | Meteorological and Environmental Research2023，14，6： | 0 |
| 17 | LDL receptor-related protein 1 (LRP1),a novel target for opening the blood-labyrinth barrier(BLB)显示文摘Inner ear disorders are a cluster of diseases that cause hearing loss in more than 1.5 billion people worldwide.However,the presence of the blood-labyrinth barrier(BLB)on the surface of the inner ear capillaries greatly hinders the effectiveness of systemic drugs for prevention and intervention due to the low permeability,which restricts the entry of most drug compounds from the bloodstream into the inner ear tissue.Here,we report the finding of a novel receptor,low-density lipoprotein receptor-related protein 1(LRP1),that is expressed on the BLB,as a potential target for shuttling therapeutics across this barrier.As a proof-ofconcept,we developed an LRP1-binding peptide,IETP2,and covalently conjugated a series of model small-molecule compounds to it,including potential drugs and imaging agents.All compounds were successfully delivered into the inner ear and inner ear lymph,indicating that targeting the receptor LRP1 is a promising strategy to enhance the permeability of the BLB.The discovery of the receptor LRP1 will illuminate developing strategies for crossing the BLB and for improving systemic drug delivery for inner ear disorders. | Xi Shi Zihao Wang Wei Ren Long Chen Cong Xu Menghua Li Shiyong Fan Yuru Xu Mengbing Chen Fanjun Zheng Wenyuan Zhang Xinbo Zhou Yue Zhang Shiwei Qiu Liyuan Wu Peng Zhou Xinze Lv Tianyu Cui Yuehua Qiao Hui Zhao Weiwei Guo Wei Chen Song Li Wu Zhong Jian Lin Shiming Yang | 2022 | Signal Transduction and Targeted Therapy2022，7，7： | 0 |
| 18 | Design of novel RGO/2D strip-like ZIF-8/DMAOP ternary hybrid structure towards high-efficiency microwave absorption, active and passive anti-corrosion, and synergistic antibacterial performance显示文摘In order to meet the requirements of the marine environment for microwave absorption(MA)materials,we put forward the strategy of constructing multi-functional composite materials,which integrate microwave absorption,anti-corrosion,and antibacterial properties.Herein,graphene oxide(GO)was used as a template to induce the growth of zeolitic imidazolate framework-8(ZIF-8),simultaneously as a two-dimensional(2D)nanocontainers to load corrosion inhibitors to achieve pH-responsive and self-healing properties.Finally,quaternary ammonium salt(dimethyl octadecyl(3-trimethoxylsilyl propyl)ammonium chloride(DMAOP))and sodium ascorbate(VCNa)were introduced to achieve synergistic antibacterial activity and the reduction of GO.The 2D strip-like structure of ZIF-8 was due to the confined growth induced by the electrostatic attraction between ZIF-8 and GO sheets.The as-obtained reduced GO(RGO)/ZIF-8/DMAOP5 exhibited excellent microwave absorption(MA)properties,with a minimum reflection loss(RL)value of-47.08 dB at 12.73 GHz when the thickness was 2.8 mm.Moreover,the effective absorption bandwidth reached 6.84 GHz.After soaking in 3.5%NaCl solution for 35 days,the RGO/ZIF-8/DMAOP5-0.7%coating still achieved an impedance value of 4.585×107Ω·cm^(2) and a protective efficiency of 99.994%,providing superior anti-corrosion properties.In addition,fantastic antibacterial activity was obtained,with the antibacterial rates of RGO/ZIF-8/DMAOP_(10) reaching 99.39%and 100%against Escherichia coli and Staphylococcus aureus.This work could open new avenues towards the development of a new generation of multifunctional MA materials. | Tanlin Chen Yingrui Tian Zihao Guo Yao Chen Qing Qi Fanbin Meng | 2024 | Nano Research2024，17，3： | 0 |
| 19 | Mechanical properties and damage characteristics of solidified body-coal combination in continuous driving and gangue backfilling显示文摘Recovery of the coal buried under buildings,railways and water bodies and the residual coal in irregularly arranged fully mechanized mining faces is a common engineering problem facing underground coal mining.In this study,a mining technology of continuous driving and gangue backfilling(CDGB)was proposed.The technology,which can not only alleviate ground subsidence and gangue discharge,but also release the above-mentioned coals,contributes to green and efficient sustainable development of mining.The stability of the system of the solidified body-reserved coal pillar combination(S-C combination)is crucial to the CDGB technology.Therefore,it is of great significance to explore the mechanical and damage characteristics of S-C combination in the synergistic bearing process.First,four sets of differentshaped S-C combination specimens were fabricated and a S-C combination bearing structure in CDGB was constructed to explore the differences in mechanical characteristics and damage modes of different-shaped S-C combination specimens during CDGB.Subsequently,their surface strain field evolutions and acoustic emission(AE)response characteristics in the load-bearing process were obtained with the aid of the digital image correlation technique and the AE signal monitoring system.Furthermore,a damage evolution model based on AE parameters and mechanical parameters was established to clarify the damage evolution law.The following results were obtained:(1)The free area of S-C combination can serve as a quantitative index to evaluate the stability of the overburden control system;(2)The concept of critical value k of the free area was first proposed.When the free area exceeds the critical value k(free area ratio greater than 1.13),the deformation resistance and the free area changes becomes negatively correlated;(3)As the free area expands,the failure of the S-C combination specimen evolves from tensile failure to shear failure.The distribution characteristics of the axial strain field also verified such a change in the failure mode;(4)When the free area expands,the peak AE count gradually changes from“double peaks”to“a single peak”.In this process,the expansion of free area shortens the time for accumulating and releasing energy during loading.Micro cracks generated in the specimen change from a phased steep growth to a continuous increase,and the process in which micro cracks develop,converge,intersect and connect to form macro cracks accelerates.The damage evolution law concluded based on AE parameters and mechanical parameters can well characterize the damage evolution process of S-C combination,providing certain reference for the study on the synergistic bearing of S-C combination during CDGB. | Yi Tan Hao Cheng Wenbing Guo Erhu Bai Shaopu Zhang Yu Wang Zihao Li | 2023 | International Journal of Mining Science and Technology2023，33，10： | 0 |
