| 1 | Effects of stem structure andcell wall components on bending strength in wheat显示文摘Morphological traits, anatomical features, chemical components and bending stress in the stems of three genotypes of wheat (Triticum aestivum L.), namely Xiaoyan54, 8602 and Xiaoyan81, were ex- amined by means of light microscopy coupled with Fourier transform infrared spectroscopy (FTIR). No- ticeable changes in morphological and anatomical traits were observed, including outer radius of stem, the ratio of stem outer radius to stem wall thickness, various tissue proportions and variations among dif- ferent types of vascular bundles. The results of chemical analysis revealed that Xiaoyan81 had the highest cellulose content in comparison with Xiao- yan54 and 8602, whereas lignin level in Xiaoyan81 was lower than that in 8602 but higher that that in Xiaoyan54. Bending stress analysis demonstrated that Xiaoyan81 may be the main target for identifica- tion, for it had the highest bending stress among the stems of three genotypes. Associated with bending stress, all the results presented here suggested that the ratio of stem wall thickness to its outer radius, schlerenchyma tissue proportion, the average num- ber of big VB per unit and the cellulose content are four important factors affecting the mechanical strength of Xiaoyan81 wheat stems, which can be considered as the key parameters for selecting varie- ties with bending stress. Therefore, it was suggested that in the selection of lodging resistant cultivars one should consider those characterized with large ratio of outer radius of stem to stem wall thickness, great-erschlerenchyma tissue proportion, high average number of big VB per unit with high cellulose content in their stems. | WANG Jian ZHU Jinmao LIN Qinqin LI Xiaojuan TENG Nianjun LI Zhensheng LI Bin ZHANG Aimin LIN Jinxing | 2006 | Chinese Science Bulletin2006，51，7： | 30 |
| 2 | Protolith ages and deformation mechanism of metamorphic rocks in the Zhangbaling uplift segment of the Tan-Lu Fault Zone显示文摘Protolith ages and Indosinian deformation mechanism of metamorphic rocks in the Zhangbaling uplift segment of the Tan-Lu Fault Zone are important, unsolved problems. Our LA-ICP-MS zircon dating work indicates that protolith ages of the greenschist-facies Zhangbaling Group are 754–753 Ma, and those of the amphibolite-facies Feidong Complex are 800–745 Ma. These rocks belong to the earliest cover of the Yangtze Plate. Their ages and metamorphic features suggest that the rocks did not come from the Dabie Orogen. The Indosinian structures in the Zhangbaling Group and lower Sinian strata formed in a flatlying ductile detachment zone with a shear sense of top-to-the-SSW whereas those in the underlying Feidong Complex are characterized by ENE-WSW inclined folds developed under a ductile regime. It is suggested therefore that the sinistral Tan-Lu Fault Zone of the Indosinian period is buried under the Hefei Basin west of the Zhangbaling uplift segment and the uplift segment is a displaced block neighboring the fault zone. Detachment deformation between the upper rigid and lower ductile crust during displacement of the Zhangbaling uplift segment resulted in the formation of the flat-lying ductile detachment zone and its underlying drag fold zone of a ductile regime. The protolith ages and deformation mechanism in the Zhangbaling uplift segment further prove sinistral origination of the Tan-Lu Fault Zone during the continent-continent collision of the North China and Yangtze plates and support the indentation model for the two-plate collision that considers the Tan-Lu Fault Zone as an oblique convergence boundary. | ZHAO Tian ZHU Guang LIN ShaoZe YAN LeJia JIANG QinQin | 2014 | Science China Earth Sciences2014，57，11： | 25 |
| 3 | Bitter receptor TAS2R138 facilitates lipid droplet degradation in neutrophils during Pseudomonas aeruginosa infection显示文摘Bitter receptors function primarily in sensing taste,but may also have other functions,such as detecting pathogenic organisms due to their agile response to foreign objects.The mouse taste receptor type-2 member 138(TAS2R138)is a member of the G-protein-coupled bitter receptor family,which is not only found in the tongue and nasal cavity,but also widely distributed in other organs,such as the respiratory tract,gut,and lungs.Despite its diverse functions,the role of TAS2R138 in host defense against bacterial infection is largely unknown.Here,we show that TAS2R138 facilitates the degradation of lipid droplets(LDs)in neutrophils during Pseudomonas aeruginosa infection through competitive binding with PPARG(peroxisome proliferator-activated receptor gamma)antagonist:A/-(3-oxododecanoyl)-L-homoserine lactone(AHL-12),which coincidently is a virulence-bound signal produced by this bacterium(P.aeruginosa).The released PPARG then migrates from nuclei to the cytoplasm to accelerate the degradation of LDs by binding PLIN2(perilipin-2).Subsequently,the TAS2R138-AHL-12 complex targets LDs to augment their degradation,and thereby facilitating the clearance of AHL-12 in neutrophils to maintain homeostasis in the local environment.These findings reveal a crucial role for TAS2R138 in neutrophil-mediated host immunity against P.aeruginosa infection. | Qinqin Pu Kai Guo Ping Lin Zhihan Wang Shugang Qin Pan Gao Colin Combs Nadeem Khan Zhenwei Xia Min Wu | 2021 | Signal Transduction and Targeted Therapy2021，6，7： | 2 |
| 4 | Interaction among inflammasome,autophagy and non-coding RNAs:new horizons for drug显示文摘Autophagy and inflammasomes are shown to interact in various situations including infectious disease,cancer,diabetes and neurodegeneration.Since multiple layers of molecular regulators contribute to the interplay between autophagy and inflammasome activation,the detail of such interplay remains largely unknown.Non-coding RNAs(ncRNAs),which have been implicated in regulating an expanding list of cellular processes including immune defense against pathogens and inflammatory response in cancer and metabolic diseases,may join in the crosstalk between inflammasomes and autophagy in physiological or disease conditions.In this review,we summarize the latest research on the interlink among ncRNAs,inflammasomes and autophagy and discuss the emerging role of these three in multiple signaling transduction pathways involved in clinical conditions.By analyzing these intriguing interconnections,we hope to unveil the mechanism inter-regulating these multiple processes and ultimately discover potential drug targets for some refractory diseases. | Qinqin Pu Ping Lin Zhihan Wang Pan Gao Shugang Qin Luqing Cui Min Wu | 2019 | Precision Clinical Medicine2019，2，3： | 1 |
| 5 | Indoor Positioning System Using Axis Alignment and Complementary IMUs for Robot Localization显示文摘An indoor positioning method for robots is presented to improve the precision of displacement measurement using only low-cost inertial measurement units(IMUs).Firstly,a high-fidelity displacement estimation for linear motion is proposed.A new robot motion model is designed as well as an axis alignment that only uses a single axis of the accelerometer.The integral error of velocity is eliminated by a new subsection calculation method.Two complementary IMUs are combined by assigning them different weights to obtain high accuracy displacement results.Secondly,an orientation estimation based on a fusion filter for the steering motion is proposed.Experiments show that the proposed method significantly improves the accuracy of linear motion measurement and is effective for the indoor positioning of a robot. | ZHOU Qinqin LEI Siyu YU Zhangguo LIN Hsien-I CHEN Xuechao ZHANG Weimin | 2017 | 机器人2017，39，3： | 1 |
| 6 | Topology-based analysis of pelagic food web structure in the central and eastern tropical Pacific Ocean based on longline observer data显示文摘The tropical Pacific Ocean supports many productive commercial fisheries.However,few studies of ecosystem structure in the tropical Pacific Ocean have been carried out.In this study,we analyzed the food web structure in the central and eastern tropical Pacific Ocean based on trophic relationships of 35 pelagic species collected by Chinese tuna longline observers from June to November in 2017.Topology indices(node degree,D;centrality indices,BC and CC;topological importance indices,TI^1,TI^3;keystone indices,K,K_t and K_b)and Key-Player algorithms(KPP-1,KPP-2)were used to select key species and construct a simplified food web combined with body size data.The Kendall rank correlation and hierarchical clustering analysis indicated that different topology indices resulted in consistent rankings of key species.Most key species were the same as those selected in other studies in the Pacific Ocean,such as Shortbill spearfish(Tetrapturus angustirostris),Swordfish(Xiphias gladius),Albacore tuna(Thunnus alalunga),cephalopods and scomber.The food web would be separated into many unconnected parts(F=0.632,FD=0.795,R^D=0.957)after the removal of the five key species,indicating the key roles of these species in the food web structure and stability.Body size was considered an influential indicator in constructing the simplified food web.This study can improve our understanding of the food web structure in the tropical Pacific Ocean and provide scientific basis for further ecosystem dynamics studies. | Qinqin Lin Jiangfeng Zhu | 2020 | Acta Oceanologica Sinica2020，39，6： | 1 |
| 7 | Lyn prevents aberrant inflammatory responses to Pseudomonas infection in mammalian systems by repressing a SHIP-1-associated signaling cluster显示文摘The pleiotropic Src kinase Lyn has critical roles in host defense in alveolar macrophages against bacterial infection,but the underlying mechanism for Lyn-mediated inflammatory response remains largely elusive.Using mouse Pseudomonas aeruginosa infection models,we observed that Lyn^(−/−)mice manifest severe lung injury and enhanced inflammatory responses,compared with wild-type littermates.We demonstrate that Lyn exerts this immune function through interaction with IL-6 receptor and cytoskeletal protein Ezrin via its SH2 and SH3 domains.Depletion of Lyn results in excessive STAT3 activation,and enhanced the Src homology 2-containing inositol-5-phopsphatase 1(SHIP-1)expression.Deletion of SHIP-1 in Lyn^(−/−)mice(double knockout)promotes mouse survival and reduces inflammatory responses during P.aeruginosa infection,revealing the rescue of the deadly infectious phenotype in Lyn deficiency.Mechanistically,loss of SHIP-1 reduces NF-κB-dependent cytokine production and dampens MAP kinase activation through a TLR4-independent PI3K/Akt pathway.These findings reveal Lyn as a regulator for host immune response against P.aeruginosa infection through SHIP-1 and IL-6/STAT3 signaling pathway in alveolar macrophages. | Rongpeng Li Lizhu Fang Qinqin Pu Ping Lin Austin Hoggarth Huang Huang Xuefeng Li Guoping Li Min Wu | 2016 | Signal Transduction and Targeted Therapy2016，1，1： | 1 |
| 8 | Fault Tolerance for Corporate Innovation:Evidence from the Reform of State-owned Enterprises显示文摘Innovation is the source of power for high-quality development,and a relaxed institutional arrangement is a necessity for promoting innovation in enterprises.This paper examines the impact of fault tolerance on corporate innovation,theoretically analyzes the positive effects of fault tolerance on stimulating innovation,and estimates the influence of fault tolerance on corporate innovation by using the panel data of listed manufacturing companies from 2007 to 2019,taking the quasi-natural experiment of fault-tolerance system in various places since the new round of stateowned enterprise(SOE)reform.This study finds that the fault-tolerance system has significantly improved the R&D investment and patent application of the pilot SOEs,but the incentive effect is mainly reflected in the utility model patents;fault-tolerance system mainly promotes corporate innovation by alleviating managers’career worries and improving governance ability.Furthermore,the fault-tolerance system is more effective for small and medium-sized SOEs with low market competition and can alleviate the restriction of agency cost on corporate innovation.In addition,the fault-tolerance system has not yet had a significant spillover effect on private enterprises.These results show that in the SOE reform,it is necessary to strengthen the institutional arrangement of fault tolerance and create a relaxed environment to encourage innovation;it is necessary to organically integrate fault-tolerancesystem design into executive measurement and corporate governance,promote faulttolerant system to be implemented in a wider range of enterprises,and enhance the incentive effect on high-quality innovation. | ZHUANG Qinqin LIN Ruixing LUO Weijie | 2023 | Frontiers of Business Research in China2023，17，1： | 0 |

| 10 | Gene2DGE: A Perl Package for Gene Model Renewal with Digital Gene Expression Data显示文摘For transcriptome analysis, it is critical to precisely define all the transcripts across the whole genome. More and more digital gene expression (DGE) scannings have indicated the presence of huge amount of novel transcripts in addition to the known gene models. However, almost all these studies still depend crucially on existing annotation. Here, we present Gene2DGE, a Perl software package for gene model renewal with DGE data. We applied Gene2DGE to the mouse blastomere transcriptome, and defined 98,532 read-enriched regions (RERs) by read clustering supported by more than four reads for each base pair. Taking advantage of this ab initio method, we refined 2,104 exonic regions (4% of a total of 48,501 annotated transcribed regions) with remarkable extension into un-annotated regions (>50 bp). For 5% of uniquely mapped reads falling within intron regions, we identified 13,291 additional possible exons. As a result, we renewed 4,788 gene models, which account for 39% of a total of 12,277 transcribed genes. Furthermore, we identified 12,613 intergenic RERs, suggesting the possible presence of novel genes outside the existing gene models. In this study, therefore, we have developed a suitable tool for re-newal of known gene models by ab initio prediction in transcriptome dissection.

| 11 | Benefit analysis of multi-approach biomass energy utilization toward carbon neutrality显示文摘To reduce greenhouse gas(GHG)emissions,biomass has been increasingly developed as a renewable and clean alternative to fossil fuels because of its carbon-neutral characteristics.China has been investigating the rational development and use of bioenergy for developing its clean energy and achieving carbon neutrality.Substituting fossil fuels with multi-source and multi-approach utilized bioenergy and corresponding carbon reduction in China remain largely unexplored.Here,a comprehensive bioenergy accounting model with a multi-dimensional analysis was developed by combining spatial,life cycle,and multi-path analyses.Accordingly,the bioenergy production potential and GHG emission reduction for each distinct type of biomass feedstock through different conversion pathways were estimated.The sum of all available organic waste(21.55 EJ yr^(-1))and energy plants on marginal land(11.77 EJ yr^(-1))in China produced 23.30 EJ of bioenergy and reduced 2,535.32 Mt CO_(2)-eq emissions,accounting for 19.48%and 25.61%of China’s total energy production and carbon emissions in 2020,respectively.When focusing on the carbon emission mitigation potential of substituting bioenergy for conventional counterparts,bioelectricity was the most effective,and its potential was 4.45 and 8.58 times higher than that of gaseous and liquid fuel alternatives,respectively.In this study,life cycle emission reductions were maximized by a mix of bioenergy end uses based on biomass properties,with an optimal 78.56%bioenergy allocation from biodiesel,densified solid biofuel,biohydrogen,and biochar.The main regional bioenergy GHG mitigation focused on the Jiangsu,Sichuan,Guangxi,Henan,and Guangdong provinces,contributing to 31.32%of the total GHG mitigation potential.This study provides valuable guidance on exploiting untapped biomass resources in China to secure carbon neutrality by 2060. | Jiaoyue Wang Jingying Fu Zhitong Zhao Longfei Bing Fengming Xi Feng Wang Jiang Dong Shiyun Wang Gang Lin Yan Yin Qinqin Hu | 2023 | The Innovation2023，4，3： | 0 |
| 12 | Genomic basis of selective breeding from the closest wild relative of large-fruited tomato显示文摘The long and intricate domestication history of the tomato(Solanum lycopersicum)includes selection sweeps that have not been fully explored,and these sweeps show significant evolutionary trajectories of domestication traits.Using three distinct selection strategies,we represented comprehensive selected sweeps from 53 Solanum pimpinellifolium(PIM)and 166 S.lycopersicum(BIG)accessions,which are defined as pseudo-domestication in this study.We identified 390 potential selection sweeps,some of which had a significant impact on fruit-related traits and were crucial to the pseudo-domestication process.During tomato pseudo-domestication,we discovered a minor–effect allele of the SlLEA gene related to fruit weight(FW),as well as the major haplotypes of fw2.2/cell number regulator(CNR),fw3.2/SlKLUH,and fw11.3/cell size regulator(CSR)in cultivars.Furthermore,18 loci were found to be significantly associated with FW and six fruit-related agronomic traits in genome-wide association studies.By examining population differentiation,we identified the causative variation underlying the divergence of fruit flavonoids across the large-fruited tomatoes and validated BRI1-EMS-SUPPRESSOR 1.2(SlBES1.2),a gene that may affect flavonoid content by modulating the MYB12 expression profile.Our results provide new research routes for the genetic basis of fruit traits and excellent genomic resources for tomato genomics-assisted breeding. | Junwei Yang Yun Liu Bin Liang Qinqin Yang Xuecheng Li Jiacai Chen Hongwei Li Yaqing Lyu Tao Lin | 2023 | Horticulture Research2023，10，8： | 0 |
| 13 | Layer-by-layer epitaxy of multi-layer MoS_(2) wafers显示文摘The 2D semiconductor of MoShas great potential for advanced electronics technologies beyond silicon.So far,high-quality monolayer MoSwafers have been available and various demonstrations from individual transistors to integrated circuits have also been shown.In addition to the monolayer,multilayers have narrower band gaps but improved carrier mobilities and current capacities over the monolayer.However,achieving high-quality multi-layer MoSwafers remains a challenge.Here we report the growth of high-quality multi-layer Mo S_(2) 4-inch wafers via the layer-by-layer epitaxy process.The epitaxy leads to well-defined stacking orders between adjacent epitaxial layers and offers a delicate control of layer numbers up to six.Systematic evaluations on the atomic structures and electronic properties were carried out for achieved wafers with different layer numbers.Significant improvements in device performances were found in thicker-layer field-effect transistors(FETs),as expected.For example,the average field-effect mobility(μFE)at room temperature(RT)can increase from~80 cm·V·sfor monolayers to~110/145 cm·V·for bilayer/trilayer devices.The highest RTμFEof 234.7 cm·V·sand record-high on-current densities of 1.70 m A·μmat Vds=2V were also achieved in trilayer MoSFETs with a high on/off ratio of>107.Our work hence moves a step closer to practical applications of 2D MoSin electronics. | Qinqin Wang Jian Tang Xiaomei Li Jinpeng Tian Jing Liang Na Li Depeng Ji Lede Xian Yutuo Guo Lu Li Qinghua Zhang Yanbang Chu Zheng Wei Yanchong Zhao Luojun Du Hua Yu Xuedong Bai Lin Gu Kaihui Liu Wei Yang Rong Yang Dongxia Shi Guangyu Zhang | 2022 | National Science Review2022，9，6： | 0 |

| 15 | Polo-like kinase 1 as a biomarker predicts the prognosis and immunotherapy of breast invasive carcinoma patients显示文摘Invasive breast carcinoma(BRCA)is associated with poor prognosis and high risk of mortality.Therefore,it is critical to identify novel biomarkers for the prognostic assessment of BRCA.Methods:The expression data of polo-like kinase 1(PLK1)in BRCA and the corresponding clinical information were extracted from TCGA and GEO databases.PLK1 expression was validated in diverse breast cancer cell lines by quantitative real-time polymerase chain reaction(qRT-PCR)and western blotting.Single sample gene set enrichment analysis(ssGSEA)was performed to evaluate immune infiltration in the BRCA microenvironment,and the random forest(RF)and support vector machine(SVM)algorithms were used to screen for the hub infiltrating cells and calculate the immunophenoscore(IPS).The RF algorithm and COX regression model were applied to calculate survival risk scores based on the PLK1 expression and immune cell infiltration.Finally,a prognostic nomogram was constructed with the risk score and pathological stage,and its clinical potential was evaluated by plotting calibration charts and DCA curves.The application of the nomogram was further validated in an immunotherapy cohort.Results:PLK1 expression was significantly higher in the tumor samples in TCGA-BRCA cohort.Furthermore,PLK1 expression level,age and stage were identified as independent prognostic factors of BRCA.While the IPS was unaffected by PLK1 expression,the TMB and MATH scores were higher in the PLK1-high group,and the TIDE scores were higher for the PLK1-low patients.We also identified 6 immune cell types with high infiltration,along with 11 immune cell types with low infiltration in the PLK1-high tumors.A risk score was devised using PLK1 expression and hub immune cells,which predicted the prognosis of BRCA patients.In addition,a nomogram was constructed based on the risk score and pathological staging,and showed good predictive performance.Conclusions:PLK1 expression and immune cell infiltration can predict post-immunotherapy prognosis of BRCA patients. | JUAN SHEN WEIYU ZHANG QINQIN JIN FUYU GONG HEPING ZHANG HONGLIANG XU JIEJIE LI HUI YAO XIYA JIANG YINTING YANG LIN HONG JIE MEI YANG SONG SHUGUANG ZHOU | 2024 | Oncology Research2024，32，2： | 0 |
| 16 | Simulating the impacts of fishing on central and eastern tropical Pacific ecosystem using multispecies size-spectrum model显示文摘The size-spectrum model has been considered a useful tool for understanding the structures of marine ecosystems and examining management implications for fisheries.Based on Chinese tuna longline observer data from the central and eastern tropical Pacific Ocean and published data,we developed and calibrated a multispecies size-spectrum model of twenty common and commercially important species in this area.We then use the model to project the status of the species from 2016 to 2050 under five constant-fishing-mortality management scenarios:(1)F=0;(2)F=F_(recent),the average fishing mortality from 2013 to 2015;(3)F=0.5F_(recent);(4)F=2F_(recent) and(5)F=3F_(recent).Several ecological indicators were used to track the dynamics of the community structure under different levels of fishing,including the mean body weight,slope of community size spectra(Slope),and total biomass.The validation demonstrated that size-at-age data of nine main catch species between our model predictions and those empirical data from assessments by the Western and Central Pacific Fisheries Commission matched well,with the R^(2)>0.9.The direct effect of fishing was the decreasing abundance of large-sized individuals.The mean body weight in the community decreased by~1500 g(21%)by 2050 when F doubled from F_(recent) to 2F_(recent).The higher the fishing mortality,the steeper the Slope was.The projection also indicated that fishing impacts reflected by the total biomass did not increase proportionally with the increasing fishing mortality.The biomass of the main target tuna species was still abundant over the projection period under the recent fishing mortality,except Albacore tuna(Thunnus alalunga).For sharks and billfishes,their biomass remained at relatively higher levels only under the F=0 scenario.The results can serve as a scientific reference for alternative management strategies in the tropical Pacific Ocean. | Qinqin Lin Yuying Zhang Jiangfeng Zhu | 2022 | Acta Oceanologica Sinica2022，41，3： | 0 |
| 17 | Current Status and Main Scientific Outcomes of the CSES Mission显示文摘This report briefly introduces the current status of the CSES(China Seismo-Electromagnetic Satellite)mission which includes the first satellite CSES 01 in-orbit(launched in February 2018),and the second satellite CSES 02(will be launched in 2023)under development.The CSES 01 has been steadily operating in orbit for over four years,providing abundant global geophysical field data,including the background geomagnetic field,the electromagnetic field and wave,the plasma(in-situ and profile data),and the energetic particles in the ionosphere.The CSES 01 platform and the scientific instruments generally perform well.The data validation and calibration are vital for CSES 01,for it aims to monitor earthquakes by extracting the very weak seismic precursors from a relatively disturbing space electromagnetic environment.For this purpose,we are paying specific efforts to validate data quality comprehensively.From the CSES 01 observations,we have obtained many scientific results on the ionosphere electromagnetic environment,the seismo-ionospheric disturbance phenomena,the space weather process,and the Lithosphere-Atmosphere-Ionosphere coupling mechanism. | ZEREN Zhima HUANG Jianping LIU Dapeng YANG Yanyan YAN Rui ZHAO Shufan ZHANG Zhenxia LIN Jian CUI Jing CHU Wei WANG Qiao LU Hengxin XU Song GUO Feng YANG Dehe ZHOU Na LIU Qinqin HUANG He WANG Jie TAN Qiao LI Wenjing LÜFangxian ZHU Keying SHEN Xuhui | 2022 | 空间科学学报2022，42，4： | 0 |
| 18 | Study on the catch,bycatch and discard of Chinese pelagic longline fisheries in the Atlantic Ocean显示文摘Catch,bycatch and discard information is important for the assessment and management of fisheries.Using Chinese pelagic tuna longline observer data from 2010 to 2018,we studied the catch composition in the Chinese pelagic tuna longline fisheries in Atlantic targeting bigeye tuna(Thunnus obesus)and bluefin tuna(Thunnus thynnus),and analyzed the survival status and discard rates of common bycatch species.A total of 55 species,including tunas,billfishes,sharks,sea turtles,cetaceans,seabirds,and other pelagic species,were observed.The results indicated that the catch composition of the Chinese pelagic tuna longline fishery targeting bigeye tuna was significantly different from that targeting bluefin tuna.The annual discard rates of common species decreased over this period.Discard rate by length and discard mortality for common species were varied among species.This is the first study to estimate catch,bycatch,and discard using Chinese pelagic tuna longline observer data in the Atlantic Ocean,which is important for the management of Chinese tuna longline fisheries in Atlantic Ocean. | Boyi Pan Jiangfeng Zhu Qinqin Lin Zhe Geng Feng Wu Yuying Zhang | 2024 | Aquaculture and Fisheries2024，9，2： | 0 |
| 19 | A Method of Disc Inclination Correction Based on the Inversion Model of Rotation Law显示文摘Under the traditional dynamic model,the conventional method for solving the rotation angle of a rigid body is to use the fixed-axis rotation law of the rigid body,but the known rotation shaft position must be used as a prerequisite.In practical work,for the rotation of a rigid body under multiple forces,solving the shaft is often a difficult problem.In this paper,we consider the rigid body of the disc is subjected to the force of uneven magnitude from multiple angles,the position of the rotating shaft is obtained by iterative inversion through the rigid body rotation law and the dichotomy method.After the position of the shaft is determined,we establish a differential equation model based on the law of rigid body rotation,the rotation angle of the rigid body thus being solved based on this model.Furthermore,an optimization algorithm such as genetic algorithm is used to search for a correction scheme to return the rigid body to equilibrium at any given deflection angle.The model and method are based on computer to explore the law of rotation,the practical application of them play an important role in studying the concentric drum movement and the balance of handling furniture. | Yanan Zhang Lin Ouyang Qinqin Li Haichen Ju | 2020 | Journal on Big Data2020，2，3： | 0 |
