| 1 | Understanding pitting corrosion behavior of AZ91 alloy and its MAO coating in 3.5%NaCl solution by cyclic potentiodynamic polarization显示文摘The pitting corrosion behavior of AZ91 alloy before and after micro-oxidation treatment in 3.5%Na Cl solution was investigated by cyclic potentiodynamic polarization(CPDP)and optical and SEM observations of corroded surfaces at different polarization potentials.The CPDP results show that both the alloy and the MAO-coated alloy suffer from pitting corrosion and it is difficult for pits to stop growth once the pits initiates.It is revealed that the air-formed Mg O film on AZ91 alloy,the MAO coating along with corrosion products(mainly Mg(OH))formed during CPDP can significantly influence the kinetics of the redox reactions of Mg,and further influence the propagation behavior of pitting corrosion.The optical and SEM images show that the corrosion products on AZ91 alloy are dense and protective but on the MAO-coated corrosion products are very loose.Such observations support the analyses of CPDP results that pits on AZ91 alloy spread to the width whereas pits on MAO-coated alloy propagate to the depth.Overall,pitting corrosion on the MAO-coated alloy can be very severe once the coating ruptures and post-treatments are necessary to provide a promising corrosion protection for the Mg alloys. | Yuxiang Liu Zhu Liu Anyang Xu Xiaoting Liu | 2022 | Journal of Magnesium and Alloys2022，10，5： | 3 |
| 2 | Homotopy Coiflets wavelet solution of electrohydrodynamic flows in a circular cylindrical conduit显示文摘In previous studies, the nonlinear problem of electrohydrodynamic(EHD)ion drag flows in a circular cylindrical conduit has been studied by several authors. However, those studies seldom involve the computation for large physical parameters such as the electrical Hartmann number and the magnitude parameter for the strength of the nonlinearity due to the existence of strong nonlinearity in these extreme cases. To overcome this faultiness, the newly-developed homotopy Coiflets wavelet method is extended to solve this EHD flow problem with strong nonlinearity. The validity and reliability of the proposed technique are verified. Particularly, the highly accurate homotopy-wavelet solution is obtained for extreme large parameters, which seems to be overlooked before.Discussion about the effects of related physical parameters on the axial velocity field is presented. | Anyang WANG Hang XU Qiang YU | 2020 | Applied Mathematics and Mechanics(English Edition)2020，41，5： | 1 |

| 6 | Effects of Three Plant Growth Regulators on Yield and Quality of Sunflower显示文摘Using Xinshikui No.5 as the experimental material,the effects of different concentrations of mepiquat chloride( 100,200,300,400,500 mg/L),chlormequat chloride( 800,1 200,1 600,2 000,2 400 mg/L) and paclobutracol( 50,75,100,125,150 mg/L) on yield and quality of sunflower were investigated.The results showed that plant growth regulators could improve the yield and quality of sunflower seeds to varying degrees.Specifically,400 mg/L mepiquat chloride( D_4),800 mg/L chlormequat chloride( C_1) and 75 mg/L paclobutracol( P_2) significantly improved disk diameter,seed weight per disc,100-seed weight,seed kernel rate and yield of sunflower; 400 mg/L mepiquat chloride( D_4),1 200 mg/L chlormequat chloride( C_2) and 75 mg/L paclobutracol( P_2) improved crude protein content,crude fat content,length and width of sunflower seeds.Based on comprehensive consideration,paclobutracol is the most appropriate plant growth regulator for improving the yield and quality of sunflower in Xinjiang,and the optimal application concentration is 75 mg/L. | Hanhua LI Wei DUAN Anyang XU Hui WU Sumei WAN Tao YANG | 2016 | Agricultural Biotechnology2016，5，5： | 0 |
| 7 | A denoising-classification neural network for power transformer protection显示文摘Artificial intelligence(AI)can potentially improve the reliability of transformer protection by fusing multiple features.However,owing to the data scarcity of inrush current and internal fault,the existing methods face the problem of poor generalizability.In this paper,a denoising-classification neural network(DCNN)is proposed,one which inte-grates a convolutional auto-encoder(CAE)and a convolutional neural network(CNN),and is used to develop a reli-able transformer protection scheme by identifying the exciting voltage-differential current curve(VICur).In the DCNN,CAE shares its encoder part with the CNN,where the CNN combines the encoder and a classifier.Based on the inter-action of the CAE reconstruction process and the CNN classification process,the CAE regards the saturated features of the VICur as noise and removes them accurately.Consequently,it guides CNN to focus on the unsaturated features of the VICur.The unsaturated part of the VICur approximates an ellipse,and this significantly differentiates between a healthy and faulty transformer.Therefore,the unsaturated features extracted by the CNN help to decrease the data ergodicity requirement of AI and improve the generalizability.Finally,a CNN which is trained well by the DCNN is used to develop a protection scheme.PSCAD simulations and dynamic model experiments verify its superior performance. | Zongbo Li Zaibin Jiao Anyang He Nuo Xu | 2022 | Protection and Control of Modern Power Systems2022，7，1： | 0 |
| 8 | Germylene-Fe complexes caused by heterometallic coupling and investigation into the 3d-4p bonding显示文摘The interpretation of heterometallic bonding nature is a basic work of inorganic chemistry.By means of intermetallic substitution of germylene anions with iron halide complexes CpFe(CO)_(2)I andβ-diketiminato Fe^Ⅱchloride,the ferrogermylene complexes 3a,3b and 4a were synthesized and structurally characterized.The structural and IR characterizations show the presence of the Ge←Feπbackbonding in molecules 3a,3b and 4a.The computational works on frontier molecular orbitals and their comparison of energy states confirmed thatσdonation andπbackbonding are both weak in these molecules,despite three complexes have longer Ge-Fe bonds,whose strength decreases slightly with the degressive electron density around Fe environment in a sequence from 3a,3b to 4a. | Yingying Qin Yongmei Kang Lei Zhang Jianping Sun Zhijing Zhang Jialei Xu Fanlong Zeng Anyang Li Wenyuan Wang Weiqun Shi | 2024 | Chinese Chemical Letters2024，35，3： | 0 |
