| 1 | Pantograph and catenary system with double pantographs for high-speed trains at 350 km/h or higher显示文摘The paper is aimed at developing an optimized design of the pantograph and catenary system with double pantographs at a speed of 350 km/h for the Wuhan-Guangzhou high-speed railway.First,the pantograph and catenary system for the Beijing-Tianjin high-speed railway was analyzed to verify whether its design objective could be fulfilled.It shows that the system is not able to satisfy the requirement of a sustainable running speed of 350 km/h.Then a new scheme for the pantograph and catenary system is proposed through optimization and renovation of the structure and parameters of the pantograph and catenary system,including the suspension type of the catenary,tension of the contact wire,and space between two pantographs.Finally,the dynamic performance of the new system was verified by simulation and line testing.The results show that the new scheme of the pantograph and catenary system for the WuhanGuangzhou high-speed railway is acceptable,in which the steady contact between the rear pantograph and the catenary at the space of 200 m can be maintained to ensure the current-collection quality.A current collection with double pantographs at a speed of 350 km/h or higher can be achieved. | Weihua ZHANG Ning ZHOU Ruiping LI Guiming MEI Dongli SONG | 2011 | Journal of Modern Transportation2011，19，1： | 8 |

| 9 | An improved draft genome sequence of hybrid Populus alba×Populus glandulosa显示文摘Populus alba × P.glandulosa clone 84 K,derived from South Korea,is widely cultivated in China and used as a model in the molecular research of woody plants because of hi gh gene transformation efficiency.Here,we combined63-fold coverage Illumina short reads and 126-fold coverage PacBio long reads to assemble the genome.Due to the hi gh heterozygosity level at 2.1% estimated by k-mer analysis,we exploited TrioCanu for genome assembly.The PacBio clean subreads of P.alba × P.glandulosa were separated into two parts according to the similarities,compared with the parental genomes of P.alba and P.glandulosa.The two parts of the subreads were assembled to two sets of subgenomes comprising subgenome A(405.31 Mb,from P.alba)and subgenome G(376.05 Mb,from P.glandulosa) with the contig N50 size of 5.43 Mb and 2.15 Mb,respectively.A high-quality P.alba × P.glandulosa genome assembly was obtained.The genome size was 781.36 Mb with the contig N50 size of 3.66 Mb and the longest contig was 19.47 Mb.In addition,a total of 176.95 Mb(43.7%),152.37 Mb(40.5%)of repetitive elements were identified and a total of 38,701 and 38,449 protein-coding genes were predicted in subgenomes A and G,respectively.For functional annotation,96.98% of subgenome A and 96.96% of subgenome G genes were annotated with public databases.This de novo assembled genome will facilitate systematic and comprehensive study,such as multi-omics analysis,in the model tree P.alba X P.glandulosa. | Xiong Huang Song Chen Xiaopeng Peng Eun-Kyung Bae Xinren Dai Guiming Liu Guanzheng Qu Jae-Heung Ko Hyoshin Lee Su Chen Quanzi Li Mengzhu Lu | 2021 | Journal of Forestry Research2021，32，4： | 1 |

| 16 | Dislocation Behavior in ZrC Particles during Elevated Temperature Compressive Deformation of a 30 vol.% ZrC_p/W Composite显示文摘A 30 vol.% ZrCp/W composite has been deformed in compression in the temperature range of 1200-1600℃.Dislocation nucleation mechanism in ZrC particles is discussed by analyzing the harmonious deformation between tungsten-matrix and ZrC particles.Thermal activation apparently increases the mobility of screw segments,resulting in the formation of many kinetics jogs and thermodynamics jogs above 1300℃.The formation mechanisms of the dislocation configurations are studied. | Taiquan Zhang Qingchang Meng Yujin Wang Yu Zhou Guiming Song | 2011 | Journal of Materials Science & Technology2011，27，6： | 0 |

| 18 | Elevated Temperature Strength of TiC_(p)/W Composites显示文摘The elevated temperature mechanical properties of TiCp,/W composites produced using powder metallurgical technique were investigated. Results show that with increasing temperature, the strength of TiCp/W composites increases gradually and reaches its maximum value at 1000℃, which is much higher than that at room temperature. The strengthening mechanisms at high temperature are attributed to dislocation strengthening and load transfer between matrix and particles. | Yujin WANG Yu ZHOU Guiming SONG Tingquan LEI | 2001 | Journal of Materials Science & Technology2001，17，1： | 0 |
