| 1 | Laparoscopic Partial Nephrectomy With Segmental Renal Artery Clamping:Technique and Clinical Outcomes显示文摘Background:Warm ischemic injury is one of the most important factors affecting renal function in partial nephrectomy(PN).The technique of segmental renal artery clamping emerges as an alternative to conventional renal artery clamping for renal hilar control.Objective:To evaluate the feasibility and efficiency of laparoscopic PN(LPN) with segmental renal artery clamping in comparison with the conventional technique.Design,setting,and participants:A total of 75 patients underwent LPN from June 2007 to November 2009.All patients had T1a or T1b tumor in one kidney and a normal contralateral kidney.Thirty-seven patients underwent surgeries with main renal artery clamping,and 38 underwent surgeries with segmental artery clamping.Intervention:All procedures were performed by the same laparoscopic surgeon.Measurements:Blood loss,operation time,warm ischemia(WI) time,and complications affected renal function before and after operation were recorded.Results and limitations:All LPNs were completed without conversion to open surgery or nephrectomy.The novel technique slightly increased WI time(p < 0.001) and intraoperative blood loss(p = 0.006),while it provided better postoperative affected renal function(p < 0.001) compared with the conventional technique.The total complication rate was 12%.Among the 38 cases where segmental renal artery clamping was performed,7 had to convert to the conventional method.Tumor size and location influenced the number of clamped segmental arteries.Long-term postoperative renal function is still awaited.Conclusions:LPN with segmental artery clamping is safe and feasible in clinical practice.It minimizes the intraoperative WI injury and improves early postoperative affected renal function compared with main renal artery clamping.(C) 2010 European Association of Urology.Published by Elsevier B.V.All rights reserved. | Shao,P.F.

| 2 | Evolution of planetary boundary layer under different weather conditions,and its impact on aerosol concentrations显示文摘一个领域实验在天津被进行,从 2010 年 9 月 930 日的中国,在表面空气污染物质上集中了于行星的边界层(PBL ) 和它的影响的进化。实验使用了三台遥感仪器,风侧面雷达( WPR ),微波辐射计( MWR )和微脉搏的激光雷达( MPL ),到检测风,温度,和喷雾器 backscattering 系数并且到的垂直侧面测量表面污染物质的垂直侧面(喷雾器,公司, SO2 , NOx ),并且也从 255-m 收集了声音的风速表数据气象学的塔。把大小基于这些, PBL 的进化被估计。平均 PBL 高度在夜间期间在 noon/afternoon-time,和 200300 m 期间是大约 10001300 m。PBL 高度和喷雾器集中是相关反的在期间清楚并且薄雾条件。当平均喷雾器集中分别地是在薄雾和晴朗天空条件下面的 52 和 17 g/m3 时,平均最大的 PBL 高度是 1.08 和 1.70 km。太阳的放射上的喷雾器和云的影响基于从 255-m 收集的声音的风速表数据被观察气象学的塔。当 PBL 的镇压结构进一步削弱了污染物质的散开时,热流动被发现被薄雾(重污染) 或云显著地减少了,它趋于压抑 PBL 的发展,导致重污染。这个可能的积极反馈周期(更多的喷雾器降低 PBL 高度更多的喷雾器) 将在大城市为重地面污染导致一个加速过程。 | Jiannong Quan Yang Gao Qiang Zhang Xuexi Tie Junji Cao Suqin Han Junwang Meng Pengfei Chen Delong Zhao | 2013 | Particuology2013，11，1： | 51 |
| 3 | Activated carbon adsorption of quinolone antibiotics in water:Performance,mechanism,and modeling显示文摘The extensive use of antibiotics has led to their presence in the aquatic environment, and introduces potential impacts on human and ecological health. The capability of powdered activated carbon(PAC) to remove six frequently used quinolone(QN) antibiotics during water treatment was evaluated to improve drinking water safety. The kinetics of QN adsorption by PAC was best described by a pseudo second-order equation, and the adsorption capacity was well described by the Freundlich isotherm equation. Isotherms measured at different p H showed that hydrophobic interaction, electrostatic interaction,and π–π dispersion force were the main mechanisms for adsorption of QNs by PAC. A p H-dependent isotherm model based on the Freundlich equation was developed to predict the adsorption capacity of QNs by PAC at different p H values. This model had excellent prediction capabilities under different laboratory scenarios. Small relative standard derivations(RSDs), i.e., 0.59%–0.92% for ciprofloxacin and 0.09%–3.89% for enrofloxacin,were observed for equilibrium concentrations above the 0.3 mg/L level. The RSDs increased to 11.9% for ciprofloxacin and 32.1% for enrofloxacin at μg/L equilibrium levels, which is still acceptable. This model could be applied to predict the adsorption of other chemicals having different ionized forms. | Hao Fu Xuebing Li Jun Wang Pengfei Lin Chao Chen Xiaojian Zhang I.H.(Mel)Suffet | 2017 | Journal of Environmental Sciences2017，29，6： | 25 |
| 4 | Near-diffraction-limited linearly polarized narrow-linewidth random fiber laser with record kilowatt output显示文摘In this paper, we propose and experimentally investigate a linearly polarized narrow-linewidth random fiber laser(RFL) operating at 1080 nm and boost the output power to kilowatt level with near-diffraction-limited beam quality using a master oscillation power amplifier. The RFL based on a half-opened cavity, which is composed of a linearly polarized narrow-linewidth fiber Bragg grating and a 500 m piece of polarization-maintained Ge-doped fiber, generates a 0.71 W seed laser with an 88 pm full width at half-maximum(FWHM) linewidth and a 22.5 dB polarization extinction ratio(PER) for power scaling. A two-stage fiber amplifier enhances the seed laser to the maximal 1.01 k W with a PER value of 17 dB and a beam quality of M_x^2=1.15 and M_y^2=1.13. No stimulated Brillouin scattering effect is observed at the ultimate power level, and the FWHM linewidth of the amplified random laser broadens linearly as a function of the output power with a coefficient of about 0.1237 pm∕W.To the best of our knowledge, this is the first demonstration of a linearly polarized narrow-linewidth RFL with even kilowatt-level near-diffraction-limited output, and further performance scaling is ongoing. | JIANGMING XU LONG HUANG MAN JIANG JUN YE PENGFEI MA JINYONG LENG JIAN WU HANWEI ZHANG PU ZHOU | 2017 | Photonics Research2017，5，4： | 20 |
| 5 | Effects of dietary supplementation of Artemisia argyi aqueous extract on antioxidant indexes of small intestine in broilers显示文摘The present study was conducted to investigate the effect of Artemisia argyi aqueous extract(AAE) on antioxidant indexes in the small intestine. A total of 192 Arbor Acre broiler chickens(one-day-old) were randomly divided into 4 treatments with 6 replicates of 8 chickens. These 4 diets were formulated by adding 0, 500,1,000 and 2,000 mg/kg AAE to the basal diet. The results showed as follows: 1) compared with the control, the total antioxidant capacity(T-AOC) in ileum for the 2,000 mg/kg treatment group was significantly increased at 21 days of age(P < 0.05); the T-AOC levels in jejunum and ileum were significantly increased in broilers supplemented with 500 mg/kg AAE at 42 days of age(P < 0.05), and the T-AOC levels in jejunum and ileum were significantly improved in 1,000 mg/kg treatment group(P < 0.01), 2) At 21 days of age, supplementation of 500 mg/kg AAE significantly increased the catalase(CAT) activity of small intestine, and the glutathione peroxidase(GSH-Px) activity of jejunum was improved(P < 0.01), meanwhile, the GSH-Px activity of duodenum and the total superoxide dismutase(T-SOD) activity of duodenum and jejunum were significantly higher than those of the control group(P < 0.05); supplementation of 1,000 mg/kg AAE significantly increased the CAT activity of duodenum and ileum and the GSH-Px activity of duodenum and jejunum(P < 0.05), and the ileum GSH-Px activity was significantly increased(P < 0.01); supplementation of 2,000 mg/kg AAE significantly increased the CAT activity of duodenum and ileum(P < 0.05). At 42 days of age, supplementation of 500 mg/kg AAE significantly increased the GSH-Px activity of ileum and the T-SOD activity of duodenum(P < 0.05),meanwhile, the T-SOD activity of jejunum was significantly increased(P < 0.01); supplementation of1,000 mg/kg AAE significantly increased the CAT activity of jejunum and the T-SOD activity of ileum(P < 0.01), and the GSH-Px activity of jejunum was significantly increased(P < 0.05); supplementation of2,000 mg/kg AAE significantly increased the T-SOD activity of ileum(P < 0.05), but significantly decreased the CAT activity of ileum and the GSH-Px activity of jejunum(P < 0.05). 3) The malondialdehyde(MDA) levels of 3 AAE supplementation groups were significantly decreased at 21 and 42 days of age(P < 0.05). The results suggested that dietary supplementation with AAE could improve the antioxidative capacity of small intestine in broilers. | Fei Zhao Binlin Shi Dengsheng Sun Hongyan Chen Manman Tong Pengfei Zhang Xiaoyu Guo Sumei Yan | 2016 | Animal Nutrition2016，，3： | 18 |

| 7 | Targeting cancer stem cell pathways for cancer therapy显示文摘Since cancer stem cells(CSCs)were first identified in leukemia in 1994,they have been considered promising therapeutic targets for cancer therapy.These cells have self-renewal capacity and differentiation potential and contribute to multiple tumor malignancies,such as recurrence,metastasis,heterogeneity,multidrug resistance,and radiation resistance.The biological activities of CSCs are regulated by several pluripotent transcription factors,such as OCT4,Sox2,Nanog,KLF4,and MYC.In addition,many intracellular signaling pathways,such as Wnt,NF-κB(nuclear factor-κB),Notch,Hedgehog,JAK-STAT(Janus kinase/signal transducers and activators of transcription),PI3K/AKT/mTOR(phosphoinositide 3-kinase/AKT/mammalian target of rapamycin),TGF(transforming growth factor)/SMAD,and PPAR(peroxisome proliferator-activated receptor),as well as extracellular factors,such as vascular niches,hypoxia,tumor-associated macrophages,cancer-associated fibroblasts,cancer-associated mesenchymal stem cells,extracellular matrix,and exosomes,have been shown to be very important regulators of CSCs.Molecules,vaccines,antibodies,and CAR-T(chimeric antigen receptor T cell)cells have been developed to specifically target CSCs,and some of these factors are already undergoing clinical trials.This review summarizes the characterization and identification of CSCs,depicts major factors and pathways that regulate CSC development,and discusses potential targeted therapy for CSCs. | Liqun Yang Pengfei Shi Gaichao Zhao Jie Xu Wen Peng Jiayi Zhang Guanghui Zhang Xiaowen Wang Zhen Dong Fei Chen Hongjuan Cui | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 12 |
| 8 | Genetic and biological characteristics of the globally circulating H5N8 avian influenza viruses and the protective efficacy offered by the poultry vaccine currently used in China显示文摘The H5N8 avian influenza viruses have been widely circulating in wild birds and are responsible for the loss of over 33 million domestic poultry in Europe, Russia, Middle East, and Asia since January 2020. To monitor the invasion and spread of the H5N8 virus in China, we performed active surveillance by analyzing 317 wild bird samples and swab samples collected from 41,172 poultry all over the country. We isolated 22 H5N8 viruses from wild birds and 14 H5N8 viruses from waterfowls. Genetic analysis indicated that the 36 viruses formed two different genotypes: one genotype viruses were widely detected from different wild birds and domestic waterfowls;the other genotype was isolated from a whopper swan. We further revealed the origin and spatiotemporal spread of these two distinct H5N8 virus genotypes in 2020 and 2021. Animal studies indicated that the H5N8 isolates are highly pathogenic to chickens, mildly pathogenic in ducks, but have distinct pathotypes in mice. Moreover, we found that vaccinated poultry in China could be completely protected against H5N8 virus challenge. Given that the H5N8 viruses are likely to continue to spread in wild birds, vaccination of poultry is highly recommended in high-risk countries to prevent H5N8 avian influenza. | Pengfei Cui Xianying Zeng Xuyong Li Yanbing Li Jianzhong Shi Conghui Zhao Zhiyuan Qu Yanwen Wang Jing Guo Wenli Gu Qi Ma Yuancheng Zhang Weipeng Lin Minghui Li Jingman Tian Dongxue Wang Xin Xing Yanjing Liu Shuxin Pan Yaping Zhang Hongmei Bao Liling Liu Guobin Tian Chengjun Li Guohua Deng Hualan Chen | 2022 | Science China(Life Sciences)2022，65，4： | 12 |
| 9 | The levels, sources and reactivity of volatile organic compounds in a typical urban area of Northeast China显示文摘Air concentrations of volatile organic compounds(VOCs) were continually measured at a monitoring site in Shenyang from 20 August to 16 September 2017. The average concentrations of alkanes, alkenes, aromatics and carbonyls were 28.54, 6.30, 5.59 and9.78 ppbv, respectively. Seven sources were identified by the Positive Matrix Factorization model based on the measurement data of VOCs and CO. Vehicle exhaust contributed the most(36.15%) to the total propene-equivalent concentration of the measured VOCs,followed by combustion emission(16.92%), vegetation emission and secondary formation(14.33%), solvent usage(10.59%), petrochemical industry emission(9.89%), petrol evaporation(6.28%), and liquefied petroleum gas(LPG) usage(5.84%). Vehicle exhaust, solvent usage and combustion emission were found to be the top three VOC sources for O_3 formation potential, accounting for 34.52%, 16.55% and 11.94%, respectively. The diurnal variation of the total VOCs from each source could be well explained by their emission characteristics,e.g., the two peaks of VOC concentrations from LPG usage were in line with the cooking times for breakfast and lunch. Wind rose plots of the VOCs from each source could reveal the possible distribution of the sources around the monitoring site. The O_3 pollution episodes during the measurement period were found to be coincident with the elevation of VOCs, which was mainly due to the air parcel from the southeast direction where petrochemical industry emission was found to be dominant, suggesting that the petrochemical industry emission from the southeast was probably a significant cause of O_3 pollution in Shenyang. | Zhuobiao Ma Chengtang Liu Chenglong Zhang Pengfei Liu Can Ye Chaoyang Xue Di Zhao Jichen Sun Yiming Du Fahe Chai Yujing Mu | 2019 | Journal of Environmental Sciences2019，31，5： | 12 |
| 10 | Progress of a novel non-oxide Si-B-C-N ceramic and its matrix composites显示文摘In the past twenty years,Si-B-C-N ceramic has attracted wide attention due to its special structure and outstanding properties.The ceramic generally has an amorphous or a nano-crystalline structure,and has excellent structural stability,oxidation resistance,creep resistance and high-temperature mechanical properties,etc.Thus,Si-B-C-N ceramic attracts many researchers and finds potential applications in transportation,aerocraft,energy,information,microelectronics and environment,etc.Much work has been carried out on its raw materials,preparation processes,structural evolution,phase equilibrium and high-temperature properties.In recent years,many researchers focus on its new preparation methods,the preparation of dense ceramic sample with large dimensions,ceramic matrix composites reinforced by carbon fiber or SiC whisker,or components with various applications.Research on Si-B-C-N ceramic will develop our insight into the relationship between structures and properties of ceramics,and will be helpful to the development of novel high-performance ceramics.This paper reviews the preparation processes,general microstructures,mechanical,chemical,electrical and optical properties,and potential applications of Si-B-C-N ceramic,as well as its matrix composites. | Pengfei ZHANG Dechang JIA Zhihua YANG Xiaoming DUAN Yu ZHOU | 2012 | Journal of Advanced Ceramics2012，1，3： | 11 |
| 11 | Yolk-shell Si/C composites with multiple Si nanoparticles encapsulated into double carbon shells as lithium-ion battery anodes显示文摘The conceptual design of yolk-shell structured Si/C composites is considered to be an effective way to improve the recyclability and conductivity of Si-based anode materials. Herein, a new type of yolk-shell structured Si/C composite (denoted as TSC-PDA-B) has been intelligently designed by rational engineering and precise control. In the novel structure, the multiple Si nanoparticles with small size are successfully encapsulated into the porous carbon shells with double layers benefiting from the strong etching effect of HF. The TSC-PDA-B product prepared is evaluated as anode materials for lithium-ion batteries (LIBs). The TSC-PDA-B product exhibits an excellent lithium storage performance with a high initial capacity of 2108 mAh g^-1 at a current density of 100 mA g^-1 and superior cycling performance of 1113 mAh g^-1 over 200 cycles. The enhancement of lithium storage performance may be attributed to the construction of hybrid structure including small Si nanoparticles, high surface area, and double carbon shells, which can not only increase electrical conductiv让y and intimate electrical contact with Si nanoparticles, but also provide built-in buffer voids for Si nanoparticles to expand freely without damaging the carbon layer. The present findings can provide some scientific insights into the design and the application of advanced Si-based anode materials in energy storage fields. | Le Hu Bin Luo Chenghao Wu Pengfei Hu Lianzhou Wang Haijiao Zhang | 2019 | Journal of Energy Chemistry2019，28，5： | 10 |

| 13 | Myeloid-specific targeting of Notch ameliorates murine renal fibrosis via reduced infiltration and activation of bone marrowderived macrophage显示文摘Macrophages play critical roles in renal fibrosis.However,macrophages exhibit ontogenic and functional heterogeneities,and which population of macrophages contributes to renal fibrosis and the underlying mechanisms remain unclear.In this study,we genetically targeted Notch signaling by disrupting the transcription factor recombination signal binding protein-JK(RBP-J),to reveal its role in regulation of macrophages during the unilateral ureteral obstruction(UUO)-induced murine renal fibrosis.Myeloid-specific disruption of RBP-J attenuated renal fibrosis with reduced extracellular matrix deposition and myofibroblast activation,as well as attenuated epithelial-mesenchymal transition,likely owing to the reduced expression of TGF-β.Mean while,RBP-J deletion significantly hampered macrophage infiltration and activation in fibrotic kidney,although their proliferation appeared unaltered.By using macrophage clearance experiment,we found that kidney resident macrophages made negligible contribution,but bone marrow(BM)-derived macrophages played a major role in renal fibrogenesis.Further mechanistic analyses showed that Notch blockade reduced monocyte emigration from BM by down-regulating CCR2 expression.Finally,we found that myeloid-specific Notch activation aggravated renal fibrosis,which was mediated by CCR2^+macrophages infiltration.In summary,our data have unveiled that myeloid-specific targeting of Notch could ameliorate renal fibrosis by regulating BM-derived macrophages recruitment and activation,providing a novel strategy for intervention of this disease. | Yali Jiang Yuanyuan Wang Pengfei Ma Dongjie An Junlong Zhao Shiqian Liang Yuchen Ye Yingying Lu Peng Zhang Xiaowei Liu Hua Han Hongyan Qin | 2019 | Protein & Cell2019，10，3： | 10 |
| 14 | Study of dynamic hydrophobicity of micro-structured hydrophobic surfaces and lotus leaves显示文摘The dynamic wetting characteristics of water droplets on silicon wafers with microscale regular pillars structures and fresh lotus leaves are investigated experimentally.We measured the static contact angle,contact angle hysteresis,and roll-off angle of water droplets on both of these superhydrophobic surfaces with a high speed contact angle meter.The dynamic contact angles and internal velocity distribution of water droplets on superhydrophobic surfaces were studied with a high-speed camera system and a particle image velocimetry (PIV) system,respectively.We found that the acceleration of water droplets when they slide off lotus leaves is greater than that of water droplets sliding off the silicon wafers with microscale pillar structures although the static contact angles of water droplets on lotus leaves are slightly smaller than those on the silicon wafers.The reason is that water droplets sliding off lotus leaves have smaller contact angle hysteresis and larger slip velocities.These results indicate that the dynamic contact angle hysteresis and sliding acceleration of liquid droplets are more suitable for reflecting the hydrophobicity of material surfaces compared with static contact angles.Our experiments also show that lotus leaves with multiscale micro/nanostructures have stronger hydrophobicity and self-cleaning properties compared with the micro-structured superhydrophobic surfaces. | HAO PengFei YAO ZhaoHui ZHANG XiWen | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，4： | 10 |
| 15 | Two-photon-excited near-infrared emissive carbon dotsas multifunctional agents for fluorescence imaging andphotothermal therapy显示文摘C dots (CDs) have shown great potential in bioimaging and phototherapy.However, it is challenging to manipulate their fluorescent properties andtherapeutic efficacy to satisfy the requirements for clinic applications. In thisstudy, we prepared S, Se-codoped CDs via a hydrothermal method anddemonstrated that the doping resulted in excitation wavelength-independentnear-infrared (NIR) emissions of the CDs, with peaks at 731 and 820 nm.Significantly, the CDs exhibited a photothermal conversion efficiency of -58.2%,which is the highest reported value for C nanostructures and is comparable tothat of Au nanostructures. Moreover, the CDs had a large two-photon absorptioncross section (-30,045 GM), which allowed NIR emissions and the photothermalconversion of the CDs through the two-photon excitation (TPE) mechanism. Invitro and in vivo tests suggested that CDs can function as new multi functionalphototheranostic agents for the TPE fluorescence imaging and photothermaltheraov of cancer cells. | Minhuan Lan Shaojing Zhao Zhenyu Zhang Li Yan Liang Guo Guangle Niu Jinfeng Zhang Junfang Zhao Hongyan Zhang Pengfei Wang Guangyu Zhu Chun-Sing Lee Wenjun Zhang | 2017 | Nano Research2017，10，9： | 9 |

| 18 | Current Status and Future Challenges of Weather Radar Polarimetry: Bridging the Gap between Radar Meteorology/Hydrology/Engineering and Numerical Weather Prediction显示文摘After decades of research and development, the WSR-88 D(NEXRAD) network in the United States was upgraded with dual-polarization capability, providing polarimetric radar data(PRD) that have the potential to improve weather observations,quantification, forecasting, and warnings. The weather radar networks in China and other countries are also being upgraded with dual-polarization capability. Now, with radar polarimetry technology having matured, and PRD available both nationally and globally, it is important to understand the current status and future challenges and opportunities. The potential impact of PRD has been limited by their oftentimes subjective and empirical use. More importantly, the community has not begun to regularly derive from PRD the state parameters, such as water mixing ratios and number concentrations, used in numerical weather prediction(NWP) models.In this review, we summarize the current status of weather radar polarimetry, discuss the issues and limitations of PRD usage, and explore potential approaches to more efficiently use PRD for quantitative precipitation estimation and forecasting based on statistical retrieval with physical constraints where prior information is used and observation error is included. This approach aligns the observation-based retrievals favored by the radar meteorology community with the model-based analysis of the NWP community. We also examine the challenges and opportunities of polarimetric phased array radar research and development for future weather observation. | Guifu ZHANG Vivek N.MAHALE Bryan J.PUTNAM Youcun QI Qing CAO ANDrew D.BYRD Petar BUKOVCIC Dusan S.ZRNIC Jidong GAO Ming XUE Youngsun JUNG Heather D.REEVES Pamela L.HEINSELMAN AlexANDer RYZHKOV Robert D.PALMER Pengfei ZHANG Mark WEBER Greg M.MCFARQUHAR Berrien MOORE III Yan ZHANG Jian ZHANG J.VIVEKANANDAN Yasser AL-RASHID Richard L.ICE Daniel S.BERKOWITZ Chong-chi TONG Caleb FULTON Richard J.DOVIAK | 2019 | Advances in Atmospheric Sciences2019，36，6： | 9 |
| 19 | All-fiberized and narrow-linewidth 5 kW power-level fiber amplifier based on a bidirectional pumping configuration显示文摘In this paper,an all-fiberized and narrow-linewidth 5 kW power-level fiber amplifier is presented.The laser is achieved based on the master oscillator power amplification configuration,in which the phase-modulated single-frequency laser is applied as the seed laser and a bidirectional pumping configuration is applied in the power amplifier.The stimulated Brillouin scattering,stimulated Raman scattering,and transverse mode instability effects are all effectively suppressed in the experiment.Consequently,the output power is scaled up to 4.92 kW with a slope efficiency of as high as approximately 80%.The 3-dB spectral width is about 0.59 nm,and the beam quality is measured to be M^(2)~1.22 at maximum output power.Furthermore,we have also conducted a detailed spectral analysis on the spectral width of the signal laser,which reveals that the spectral wing broadening phenomenon could lead to the obvious decrease of the spectral purity at certain output power.Overall,this work could provide a reference for obtaining and optimizing high-power narrow-linewidth fiber lasers. | Pengfei Ma Hu Xiao Wei Liu Hanwei Zhang Xiaolin Wang Jinyong Leng Pu Zhou | 2021 | High Power Laser Science and Engineering2021，9，3： | 9 |
| 20 | Design and test of robotic harvesting system for cherry tomato显示文摘Harvesting of fresh-eating cherry tomato was highly costly on labor and time.In order to achieve mechanical harvesting for the fresh-eating tomato,a new harvesting robot was designed,which consisted of a stereo visual unit,an end-effector,manipulator,a fruit collector,and a railed vehicle.The robot configuration and workflow design focused on the special cultivating condition.Three key parts were introduced in detail:a railroad vehicle capably moving on both ground and rail was adopted as the robot’s carrier,a visual servo unit was used to identify and locate the mature fruits bunch,and the end-effector to hold and separate the fruit bunch was designed based on the stalk’s mechanical features.The field test of the new developed robot was conducted and the results were analyzed.The successful harvest rate of the robot was 83%,however,each successful harvest averagely needed 1.4 times attempt,and a single successful harvesting cycle cost 8 s excluding the time cost on moving. | Qingchun Feng Wei Zou Pengfei Fan Chunfeng Zhang Xiu Wang | 2018 | International Journal of Agricultural and Biological Engineering2018，11，1： | 8 |
