| 1 | Early evaluation of growth traits of Larix kaempferi clones显示文摘Early selection is an important method to shorten the breeding cycle for tree species, which may differ in the time for early selection.To evaluate the early selected time for Larix kaempferi, tree height and diameter at breast height of 57 L.kaempferi clones were measured over many different growth years.The results indicated that, except for age × clone interaction for diameter at breast height(P = 0.741), there were significant differences among all variation sources(P < 0.01).The coefficient of phenotypic variation ranged from 14.89 to 35.65%for height and from 19.17 to 23.86% for diameter at breast height in different growth years.The repeatability of height and of diameter at breast height among clones was high,ranging from 0.6181 to 0.8531(height) and from 0.8443 to0.8497(diameter at breast height), in different growth years.There were significant positive correlations between all pairs of growth traits except between height in the 2 nd growth year and height in the 30 th growth year; and between height in the 2 nd growth year × diameter at breast height in the 30 th growth year.With a comprehensive evaluation method and a selection ratio of 10%, L65,L1, L62, L9, L15, and L78 were selected as excellent clones in the 30 th growth year.Their average values of height and diameter at breast height were 9.81 and 16.57%higher than the overall average, representing genetic gains of 6.46 and 13.99%, respectively.This study provides a theoretical foundation for the genetic improvement of L.kaempferi. | Yanyan Pan Shuchun Li Chenglu Wang Wenjun Ma Guiyou Xu Lili Shao Kailong Li Xiyang Zhao Tingbo Jiang | 2018 | Journal of Forestry Research2018，29，4： | 10 |
| 2 | Reducing the yield asymmetry in Mg-5Li-3Al-2Zn alloy by hot-extrusion and multi-pass rolling显示文摘Reducing the yield asymmetry is very important concern for wrought Mg-Li alloys.In this study,Mg-5Li-3Al-2 Zn(LAZ532)alloy was successfully produced by hot-extrusion followed by multi-pass rolling at 573 K.Microstructure evolution,mechanical properties and yield asymmetry reducing of LAZ532 alloys at different rolling passes were studied.By observing microstructure using transmission electron microscopy showed that a small amount of ultra-fine Al Mg_(4)Zn_(11)and nano Li_(3)Al_(2) phases existed in the alloy.With the increasing of rolling passes,the grains of the alloys were obviously refined,and comprehensive mechanical properties were dramatically improved.Meanwhile,it also showed an excellent tension and compression yield symmetry(TYS/CYS was about 1).The results showed that the combined action of the weak{0001}basal lamellar texture,grain refinement and addition of Li element could effectively improve the yield symmetry.Furthermore,based on theoretical analysis,the yield strength in the alloys mainly depended on the strengthening contributions of LAGBs and HAGBs,and strengthening effect of HAGBs most(~50%)to the yield strength improvement. | Xiaoqiang Li Liang Ren Qichi Le Lei Bao Peipeng Jin Ping Wang Chunlong Cheng Xiong Zhou Chenglu Hu | 2021 | Journal of Magnesium and Alloys2021，9，3： | 4 |
| 3 | Investigation of Portevin–Le Chatelier effect in rolled α-phase Mg-Li alloy during tensile and compressive deformation显示文摘Avoiding the Portevin-Le Chatelier(PLC)effect is very important concern for wrought Mg-Li alloys.In this study,the special PLC effect was found in rolled Mg-5Li-3Al-2Zn(LAZ532)alloy during tensile and compressive deformation.By observing microstructure evolution of the alloy during tensile and compressive deformation,it was found that prismaticand pyramidalslips were activated during tensile deformation,resulting in plenty of dislocation accumulation.In the deformation process after compressive yielding,the deformations in coarse grains and fine grains were dominated by{1012}extension twinning and grain boundary slip,respectively.Based on experimental result analysis,the sudden appearance of PLC effect in the later stage of axial tensile deformation(along rolled direction)was caused by interaction between solute atoms and dislocations.In the process of axial compressive deformation(along rolled direction),PLC effect presented the complex and changeable phenomenon of appeared-disappeared-appeared,which was mainly caused by the continuous nucleation of twin in the material,the activation of grain boundary slip and the shear deformation of twin,respectively. | Xiaoqiang Li Chunlong Cheng Qichi Le Lei Bao Peipeng Jin Ping Wang Liang Ren Hang Wang Xiong Zhou Chenglu Hu | 2020 | Journal of Materials Science & Technology2020，52，17： | 3 |

| 9 | Urban 3D modeling using mobile laser scanning:a review显示文摘Mobile laser scanning(MLS)systems mainly comprise laser scanners and mobile mapping platforms.Typical MLS systems can acquire three-dimensional point clouds with 1-10cm point spacings at a normal driving or walking speed in streets or indoor environments.The efficiency and stability of these systems make them extremely useful for application in three-dimensional urban modeling.This paper reviews the latest advances of the LiDAR-based mobile mapping system(MMS)point cloud in the field of 3D modeling,including LiDAR simultaneous localization and mapping,point cloud registration,feature extraction,object extraction,semantic segmentation,and processing using deep learning.Furthermore,typical urban modeling applications based on MMS are also discussed. | Cheng WANG Chenglu WEN Yudi DAI Shangshu YU Minghao LIU | 2020 | Virtual Reality & Intelligent Hardware2020，2，3： | 0 |
| 10 | Mechanical Properties and Corrosion Behavior of Multi-Microalloying Mg Alloys Prepared by Adding AlCoCrFeNi Alloy显示文摘In this work,a series of multi-microalloying Mg alloys with a high degradation rate and high strength was prepared by adding AlCoCrFeNi HEA particles to the Mg melt followed by hot extrusion.The microstructure evolution and mechanical properties of the alloys were studied,meanwhile,the corrosion properties were evaluated by immersion weight loss and electrochemical tests.Results indicated that HEA particles in the Mg melt were decomposed and formed the Ni-rich phase,which was distributed uniformly in the Mg matrix.Compared with the pure Mg matrix,the Mg-3 HEA alloy exhibited excellent mechanical properties of the ultimate tensile strength~237 MPa and tensile yield strength~181 MPa,an increased rate of~49.1 and~96.7%,respectively,without sacrificing the elongation.And the ultimate compressive strength(UCS)and compressive yield strength increased by~31.5 and~43%to 392±3 and 103±2 MPa,respectively.Based on theoretical analysis,the high YS of the alloys was mainly attributed to fine-grain strengthening and second phase strengthening.Besides,based on the study of corrosion behavior,it was found that with the increase in HEA particle content,the degradation rate of the composites increased because of the promotion of micro-galvanic corrosion,and the Mg-3 HEA alloy showed a maximum degradation rate of~25.2 mg cmh. | Xiong Zhou Qichi Le Chenglu Hu Ruizhen Guo Tong Wang Chunming Liu Dandan Li Xiaoqiang Li | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，8： | 0 |
| 11 | Construction of the glucose isomerase deficient strain of Streptomyces M1033 by homologous recombination显示文摘After the establishment of the transformation conditions of Streptomyces diastaticus No.7 Strain M1033, the integration plasmid pXW for homologous recombination, which contains a 600 bp fragment of incomplete Gl (G138P. G247D) gene, has been constructed in order to realize the stable overexpression of the Gl (G138P. G247D) which is valuable for large-scale industrial production. The G/gene’s disruption has been realized by pXW’s integration into M1033 chromosomes via homologous recombination and Gl deficient strain of Streptomyces M1033 has been obtained.

| 12 | Investigation of silicon on insulator fabricated by two-step O^+ implantation显示文摘In this paper,we investigated the dose window of forming a continuous buried oxide(BOX) layer by single implantation at the implantation energy of 200 keV. Then,an improved two-step implantation process with second implantation dose of 3×1015 cm-2 was developed to fabricate high quality separation by implanted oxygen(SIMOX) silicon on insulator(SOI) wafers. Compared with traditional single implantation,the implantation dose is reduced by 18.2%. In addition,the thickness and uniformity of the BOX layers were evaluated by spectroscopic ellipsometry. Defect-free top Si as well as atomic-scale sharp top Si/buried oxide interfaces were observed by transmission electron microscopy,indicating a high crystal quality and a perfect structure of the SOI fabricated by two step implantation. The top Si/BOX interface morphology of the SOI wafers fabricated by single or two-step implantation was also investigated by atomic force microscopy. | WEI Xing XUE ZhongYing WU AiMin WANG Xiang LI XianYuan YE Fei CHEN Jie CHEN Meng ZHANG Box LIN ChengLu ZHANG Miao WANG Xi | 2011 | Chinese Science Bulletin2011，56，4： | 0 |
| 13 | Photo-induced Ag modulating carbon dots:Greatly improved fluorescent properties and derived sensing application显示文摘Carbon dots(CDs)have been attracted much attention and widely studied due to their excellent fluorescence(FL)properties,better biocompatibility and outstanding photo/chemical stability.However,the disadvantage of lower quantum yield(QY)still limits its wide application.Herein,we reported a novel and convenient strategy to prepare photo-induced Ag/CDs(p-Ag/CDs)by irradiating the mixed Ag+and hydrophobic CDs(h-CDs)acetone solution with ultraviolet(UV)light.The obtained p-Ag/CDs exhibit a greatly enhanced FL emission together with a blue shift(460 nm)than h-CDs(520 nm).The QY of p-Ag/CDs is measured to be 51.1%,which is 10.4 times higher than that of h-CDs(4.9%),indicating that photo-induced Ag modulation can effectively improve the optical properties of CDs.The mechanisms for the FL enhancement and blue shift of h-CDs are studied in detail.The results prove that the greatly enhanced FL emission is from the generated Ag nanoparticles(AgNPs)by UV light irradiation based on metal-enhanced fluorescence(MEF),and the increased oxygen-contained groups in this process lead to the blue shift in CDs fluorescence.Interestingly,the p-Ag/CDs exhibit higher sensitivity and selectivity for sulfide ions(S2-)detection than that of h-CDs,which have a lower response to S2-.This work not only offers a novel strategy to improve the FL properties of materials but also endows them with new functions and broadens their application fields. | Yuwei Wang Ye Li Guixiang Yang Xiaofeng Yang Chenglu Yan Huaqiao Peng Huiyong Wang Juan Du Baozhan Zheng Yong Guo | 2024 | Chinese Chemical Letters2024，35，1： | 0 |
| 14 | BLNet:Bidirectional learning network for point clouds显示文摘The key challenge in processing point clouds lies in the inherent lack of ordering and irregularity of the 3D points.By relying on per-point multi-layer perceptions(MLPs),most existing point-based approaches only address the first issue yet ignore the second one.Directly convolving kernels with irregular points will result in loss of shape information.This paper introduces a novel point-based bidirectional learning network(BLNet)to analyze irregular 3D points.BLNet optimizes the learning of 3D points through two iterative operations:feature-guided point shifting and feature learning from shifted points,so as to minimise intra-class variances,leading to a more regular distribution.On the other hand,explicitly modeling point positions leads to a new feature encoding with increased structure-awareness.Then,an attention pooling unit selectively combines important features.This bidirectional learning alternately regularizes the point cloud and learns its geometric features,with these two procedures iteratively promoting each other for more effective feature learning.Experiments show that BLNet is able to learn deep point features robustly and efficiently,and outperforms the prior state-of-the-art on multiple challenging tasks. | Wenkai Han Hai Wu Chenglu Wen Cheng Wang Xin Li | 2022 | Computational Visual Media2022，8，4： | 0 |
