| 1 | Molten salts-modified MgO-based adsorbents for intermediate-temperature CO_2 capture: A review显示文摘Carbon dioxide(CO2) capture using magnesium oxide(MgO)-based adsorbents at intermediate temperatures has been regarded as a very prospective technology for their relatively high adsorption capacity,low cost, and wide availability. During the past few years, great effort has been devoted to the fabrication of molten salts-modified MgO-based adsorbents. The extraordinary progress achieved by coating with molten salts greatly promotes the CO_2 capture capacity of MgO-based adsorbents. Therefore, we feel it necessary to deliver a timely review on this type of CO_2 capturing materials, which will benefit the researchers working in both academic and industrial areas. In this work, we classified the molten saltsmodified MgO adsorbents into four categories:(1) homogenous molten salt-modified MgO adsorbents,(2) molten salt-modified double salts-based MgO adsorbents,(3) mixed molten salts-modified MgO adsorbents, and(4) molten salts-modified MgO-based mixed oxides adsorbents. This contribution critically reviews the recent developments in the synthetic method, adsorption capacity, reaction kinetics, promotion mechanism, operational conditions and regenerability of the molten salts-modified MgO CO_2 adsorbents. The challenges and prospects in this promising field of molten salts-modified MgO CO_2 adsorbents in real applications are also briefly mentioned. | Wanlin Gao Tuantuan Zhou Yanshan Gao Benoit Louis Dermot O'Hare Qiang Wang | 2017 | Journal of Energy Chemistry2017，26，5： | 12 |

| 3 | Progress,problems and prospects for standardization of greenhouse-related technologies显示文摘In recent years,the scale of greenhouse grows rapidly and steadily in China,which promotes the development of greenhouse technology and the demand for standardized technology.However,the standardization process of greenhouse industry in China has been facing with the problem of unbalanced development with the practical standard system for many years.To solve these problems,the most characteristic greenhouse designs used in China contributing to this work are presented in detail.And the development of standard system and the standardization efforts of them are summarized and analyzed in relationship to the data presented in this paper.In this way the origin of greenhouse standard system in China and context of the system development and standardization of greenhouse structure are clarified.It was also found that the development and iterative update of greenhouse standard system are under the influences of enterprises which as the participation of standard constitutors were proved to play an important role in promoting the standardization development of greenhouse.The outcome of this work may be utilized to perfect the greenhouse standardization system and improve the greenhouse standardization efficiency that dominate the facility agriculture in China. | Yanzhao Ren Minjuan Wang Iftikhar Ahmed Saeeda Xuerui Chen Wanlin Gao | 2018 | International Journal of Agricultural and Biological Engineering2018，11，1： | 4 |
| 4 | Spray drift characteristics test of unmanned aerial vehicle spray unit under wind tunnel conditions显示文摘Since the 2010s,unmanned aerial vehicle(UAV)sprayer was applied more and more widely for low-volume aerial pesticides spraying operations in China.However,droplets from the UAV sprayer have a higher drift risk due to more fine droplets sprayed and a higher flight height than ground sprayers.Study on UAV spray drift has been a new hot spot within the field of pesticide application technology.Most of previous studies used direct field methods for spray drift,but the meteorological conditions in field were unstable and uncontrollable,and drift research under an actual operation state in wind tunnel has not been reported.Therefore,25 treatments of wind tunnel measurements and droplets spectrum tests of 10 models of nozzles were conducted to explore the influence factor on spray drift characteristics of UAV chemicals application in this study.A spray unit with a rotor of UAV was innovatively installed in wind tunnel,and the airstream from the wind tunnel was regarded as the relative moving natural wind to simulate the flight status.The airborne and the sediment spray drift was measured to study the effects of the nozzle type and size(flat fan,hollow cone and air-inclusion nozzles),flight speed,adjuvant(DRS-60,Y-20079,MF and G-611)and meteorological parameters(20°C&40%,20°C&80%,30°C&40%and 30°C&60%).The drift potential(DP)and the drift potential reduction percentage(DPRP)in vertical and horizontal directions were obtained for each test.Both nozzle type and size had an impact on the spray drift potential obviously by affecting the droplet size and the ratio of fine droplets,and the regression linear models between DPRPV/DPRPH and DV50,V75 were established(R2=0.934/0.925).Flight speed also had a significant effect on the spray drift characteristics,and reducing the flight speed could increase the DP effectively.Adding spray adjuvants could affect the DP under experimental meteorological parameters,and the anti-drift performance ranked in the order of DRS-60>MF>Y-20079>G-611.Recommendations were proposed in order to reduce the spray drift for UAV sprayer’s operation.These findings can contribute to provide guidelines and technical support for the wind tunnel spray drift tests of UAV and the field operation regulation of unmanned aerial PPP application. | Changling Wang Aijun Zeng Xiongkui He Jianli Song Andreas Herbst Wanlin Gao | 2020 | International Journal of Agricultural and Biological Engineering2020，13，3： | 3 |

| 7 | Fuzzy intelligent control method for improving flight attitude stability of plant protection quadrotor UAV显示文摘At present,the attitude control method of plant protection UAV is the classical PID control,but there are some imperfections in the PID control,such as the contradiction between speediness and overshoot,the weak anti-jamming ability and adaptability.The physical parameters of plant protection UAV are time-varying,and the airflow also interferes with it.The control ability of classical PID is limited,and its control parameters are fixed,and its anti-jamming ability and adaptability are not strong.Therefore,a fuzzy adaptive PID controller is proposed in this paper.Fuzzy logic control is used to optimize the control parameters of PID in order to improve the dynamic and static performance and adaptability of attitude control of plant protection UAV.In the process of research,the mathematical model of UAV is established firstly,then the fuzzy adaptive PID is designed,and then the simulation is carried out in Simulink.The simulation results show that the fuzzy adaptive PID controller has better dynamic and static control performance and adaptability than the traditional PID controller.Therefore,the proposed control method has excellent application value in the attitude of plant protection UAV. | Zhihui He Wanlin Gao Xiongkui He Minjuan Wang Yunling Liu Yue Song Zewu An | 2019 | International Journal of Agricultural and Biological Engineering2019，12，6： | 1 |
| 8 | Online ultrasonic terminal for measuring pig backfat thickness显示文摘The measurement of pig backfat thickness(PBFT)has to stand up to challenges with the reliability,accuracy,and convenience.Acquiring PBFT timely and precisely from a finite distance is extremely necessary to improve the process of pig production and implement effective management.In an attempt to alleviate these problems,an online handheld terminal was designed with a new method based on ultrasonic technology for measuring PBFT during the process of pig breeding,which can overcome the difficulties encountered in other destructive means.The terminal comprised three main components:a main microcontroller unit(MCU)to measure PBFT,a RFID module to identify each pig and send data(e.g.identity,measurement time and PBFT)to a server via wireless transmission module,and an ultrasonic transducer to drive and receive signals between them.A measurement error within 0-1 mm was acquired through testing three groups of samples.Results indicated that this handheld terminal had a required accuracy and proved that the ultrasonic wave processing method can be deployed in a mobile terminal for PBFT measurement.It also provided a feasible nondestructive alternative to measure PBFT.Associated with information management software platform,this method may ultimately help pig production farmers measure the PBFT accurately and conveniently,and improve the pig production efficiency. | Ganghong Zhang Wanlin Gao Sha Tao Lina Yu Guofeng Zhang Xuan Luo | 2018 | International Journal of Agricultural and Biological Engineering2018，11，2： | 1 |

| 10 | Wetting behavior of CaO-Al_(2)O_(3)-based mold flux with various BaO and MgO contents on the steel substrate显示文摘The Interfacial phenomena in mold have a great impact on the smooth operation of continuous casting process and the quality of the casting product.In this paper,the wetting behavior of CaO-Al_(2)O_(3)-based mold flux with different BaO and MgO contents was studied.The results showed that the contact angle between molten flux and interstitial free(IF)steel substrate increased from 62.4°to 74.5°with the increase of BaO content from 3 wt%to 7 wt%,while it decreased from 62.4°to 51.3°with the increase of MgO content from 3 wt%to 7 wt%.The interfacial tension also increased from 1630.3 to 1740.8 mN/m when the BaO content increased,but it reduced from 1630.3 to 1539.7 mN/m with the addition of MgO.The changes of contact angle and interfacial tension were mainly due to the fact that the bridging oxygen(O^(0)) at the interface was broken into non-bridging oxygen(O^(-)) and free oxygen(O_(2-)) by MgO.However,more O^(-) and O_(2-) connected into O^(0) when BaO was added,since the charge compensation effect of BaO was so stronger that it offset the effect of providing O_(2-). | Lejun Zhou Hao Luo Wanlin Wang Houfa Wu Erzhuo Gao You Zhou Daoyuan Huang | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，6： | 0 |

| 12 | Identification of damaged corn seeds using air-coupled ultrasound显示文摘Corn,an important staple in many countries around the world,is subject to a very inefficient germination rate due to worm-damaged seeds.However,air-coupled ultrasound is a rapid,safe and widely accepted method for the early detection of such damage.In this study,the current effectiveness and future prospects of this technique for identifying damaged seeds were explored.The presented procedure started with drawing a sample of 810 seed particles,consisting of 400 that were intact,400 manually damaged and 10 damaged by worms.Then the principal component analysis(PCA)method was used to reduce the dimensions of air-coupling ultrasonic information and extract the top ten principal components.Finally,a KNN decision tree by using SIMCA software and a Fisher recognition model by using MATLAB software were constructed.The pattern recognition was established by using KNN,which has the most accurate recognition rate.The correct recognition rate of modeling for the front and back data of the intact particles was 98%and 100%,respectively;and for the manually damaged particles,99%and 97%,respectively.The results show that the model developed by using air-coupled ultrasonic data can classify corn seed particles both with and without holes to provide a basis for the development of a seed selection system,which has a significant role in improving the clarity and the germination rate. | Jin Yanyun Gao Wanlin Zhang Han An Dong Guo Sihan Saeed Iftikhar Ahmed Liu Yunling | 2016 | International Journal of Agricultural and Biological Engineering2016，9，1： | 0 |
| 13 | Defect-rich Mg-Al MMOs supported TEPA with enhanced charge transfer for highly efficient and stable direct air capture显示文摘Due to the advantages of low energy consumption and high CO_(2) selectivity, the development of solid amine-based materials has been regarded as a hot research topic in the field of DAC for the past decades.The adsorption capacity and stability over multiple cycles have been the top priorities for evaluation of practical application value. Herein, we synthesized a novel DAC material by loading TEPA onto defect-rich Mg_(0.55)Al-O MMOs with enhanced charge transfer effect. The optimal Mg_(0.55)Al-O-TEPA67% demonstrates the highest CO_(2)uptake of(3.0 mmol g^(-1)) and excellent regenerability, maintaining ~90% of the initial adsorption amount after 80 adsorption/desorption cycles. The in situ DRIFTS experiments suggested the formation of bicarbonate species under wet conditions. DFT calculations indicated that the stronger bonding between Mg_(0.55)Al-O support and solid amine was caused by the abundance of oxygen defects on MMOs confirmed by XPS and ESR, which favors the charge transfer between the support and amine,resulting in intense interaction and excellent regenerability. This work for the first time conducted comprehensive and systematic investigation on the stabilization mechanism for MMOs supported solid amine adsorbents with highest uptake and superior cyclic stability in depth, which is different from the most popular SiO_(2)-support, thus providing facile strategy and comprehensive theoretical mechanism support for future research about DAC materials. | Meng Zhao Jiewen Xiao Wanlin Gao Qiang Wang | 2022 | Journal of Energy Chemistry2022，31，5： | 0 |
| 14 | A multiple coupling approach to produce high-performance SERS substrates显示文摘Creating hotspots with significantly enhanced electromagnetic(EF) field, efficiently placing target molecules in hotspot region, and achieving uniform and reproducible Raman signals are three critical issues for developing high-performance SERS substrates. In this work, large area gold nanoparticle cluster pillar array with a gold mirror at bottom was facilely fabricated by combined use of nanosphere lithography and self-assembly approach. It is both theoretically and experimentally found that through multiple coupling interactions, the electromagnetic fields at interparticle gaps within the gold clusters were significantly enhanced in our three-dimentional(3D) pillar array substrates, which can result in one order of magnitude stronger as compared with random gold clusters on a two-dimentional planar case.Due to the periodic stucture, our substrates also possess the capbility of producing highly uniform and reproducible SERS signals. Attractively, in our case, a photoresponsive polymer was used for the formation of pillar array structure. Its unique photoinduced deformation makes it possible to reversibly open and close the gaps of the closely packed Au NP array, thus enabling efficient placement or entrapment of probe molecules into hotspot sites between adjacent nanoparticles. | Xianpeng Yin Hao Dong Shiqiang Wang Yun Liang Ning Gao Wanlin Zhang Li Tian Fuwei Sun Guangtao Li | 2019 | Chinese Chemical Letters2019，30，1： | 0 |
| 15 | Discovery and inspiration of large-and medium-sized glutenite-rich oil and gas fields in the eastern South China Sea:An example from Paleogene Enping Formation in Huizhou 26 subsag,Pearl River Mouth Basin显示文摘Based on the practice of oil and gas exploration in the Huizhou Sag of the Pearl River Mouth Basin,the geochemical indexes of source rocks were measured,the reservoir development morphology was restored,the rocks and minerals were characterized microscopically,the measured trap sealing indexes were compared,the biomarker compounds of crude oil were extracted,the genesis of condensate gas was identified,and the reservoir-forming conditions were examined.On this basis,the Paleogene Enping Formation in the Huizhou 26 subsag was systematically analyzed for the potential of oil and gas resources,the development characteristics of large-scale high-quality conglomerate reservoirs,the trapping effectiveness of faults,the hydrocarbon migration and accumulation model,and the formation conditions and exploration targets of large-and medium-sized glutenite-rich oil and gas fields.The research results were obtained in four aspects.First,the Paleogene Wenchang Formation in the Huizhou 26 subsag develops extensive and thick high-quality source rocks of semi-deep to deep lacustrine subfacies,which have typical hydrocarbon expulsion characteristics of'great oil generation in the early stage and huge gas expulsion in the late stage',providing a sufficient material basis for hydrocarbon accumulation in the Enping Formation.Second,under the joint control of the steep slope zone and transition zone of the fault within the sag,the large-scale near-source glutenite reservoirs are highly heterogeneous,with the development scale dominated hierarchically by three factors(favorable facies zone,particle component,and microfracture).The(subaqueous)distributary channels near the fault system,with equal grains,a low mud content(<5%),and a high content of feldspar composition,are conducive to the development of sweet spot reservoirs.Third,the strike-slip pressurization trap covered by stable lake flooding mudstone is a necessary condition for oil and gas preservation,and the NE and nearly EW faults obliquely to the principal stress have the best control on traps.Fourth,the spatiotemporal configuration of high-quality source rocks,fault transport/sealing,and glutenite reservoirs controls the degree of hydrocarbon enrichment.From top to bottom,three hydrocarbon accumulation units,i.e.low-fill zone,transition zone,and high-fill zone,are recognized.The main area of the channel in the nearly pressurized source-connecting fault zone is favorable for large-scale hydrocarbon enrichment.The research results suggest a new direction for the exploration of large-scale glutenite-rich reservoirs in the Enping Formation of the Pearl River Mouth Basin,and present a major breakthrough in oil and gas exploration. | XU Changgui GAO Yangdong LIU Jun PENG Guangrong LIU Pei XIONG Wanlin SONG Penglin | 2024 | Petroleum Exploration and Development2024，51，1： | 0 |
| 16 | Research on Improved Character Encoding Methods Based on QR Code显示文摘With the popularity of mobile terminals,Quick response(QR)code,which acts as a convenient and quick way to transfer graphic information,has been widely used in various fields.QR code is a 2D matrix code which contains information in both vertical and horizontal directions.In order to promote the characters encoding efficiency,we propose the improved character encoding methods based on QR code.Specifically,we divide the types of encoding data into Chinese characters and nonChinese characters,and thus optimizing their encoding methods separately:we apply the branch-bound algorithm to optimize the encoding pattern selection of QR code;as for Chinese characters,based on the Chinese characters use frequency generated by Url crawler system,we design a new encoding method for Chinese characters.Our approach has been shown to afford better experimental test results compared with traditional encoding methods of QR code. | KANG Bohan JIA Jingdun GAO Wanlin ZHANG Ning | 2019 | Chinese Journal of Electronics2019，28，6： | 0 |
| 17 | A nonparametric variable step-size subband adaptive filtering algorithm for acoustic echo cancellation显示文摘Acoustic echo cancellation is often applied in communication and video call system to reduce unnecessary echoes generated between speakers and microphones.In these systems,the speech input signal of the adaptive filter is often colored and unstable,which decays the convergence rate of the adaptive filter if the NLMS algorithm is used.In this paper,an improved nonparametric variable step-size subband(NPVSS-NSAF)algorithm is proposed to address the problem.The variable step-size is derived by minimizing the sum of the square Euclidean norm of the difference between the optimal weight vectors to be updated and the past estimated weight vectors.Then the parameters are eliminated by using the power of subband signal noise equal to the power of subband posteriori error.The performance of the proposed algorithm is simulated in the aspects of misalignment and return loss enhancement.Experiment results show a fast convergence rate and low misalignment of the proposed algorithm in system identification. | Yue Song Yanzhao Ren Xinliang Liu Wanlin Gao Sha Tao Lin Guo | 2020 | International Journal of Agricultural and Biological Engineering2020，13，3： | 0 |

| 19 | Association rule mining algorithm based on Spark for pesticide transaction data analyses显示文摘With the development of smart agriculture,the accumulation of data in the field of pesticide regulation has a certain scale.The pesticide transaction data collected by the Pesticide National Data Center alone produces more than 10 million records daily.However,due to the backward technical means,the existing pesticide supervision data lack deep mining and usage.The Apriori algorithm is one of the classic algorithms in association rule mining,but it needs to traverse the transaction database multiple times,which will cause an extra IO burden.Spark is an emerging big data parallel computing framework with advantages such as memory computing and flexible distributed data sets.Compared with the Hadoop MapReduce computing framework,IO performance was greatly improved.Therefore,this paper proposed an improved Apriori algorithm based on Spark framework,ICAMA.The MapReduce process was used to support the candidate set and then to generate the candidate set.After experimental comparison,when the data volume exceeds 250 Mb,the performance of Spark-based Apriori algorithm was 20%higher than that of the traditional Hadoop-based Apriori algorithm,and with the increase of data volume,the performance improvement was more obvious. | Xiaoning Bai Jingdun Jia Qiwen Wei Shuaiqi Huang Weicheng Du Wanlin Gao | 2019 | International Journal of Agricultural and Biological Engineering2019，12，5： | 0 |
