| 1 | Community structure and elevational diversity patterns of soil Acidobacteria显示文摘Acidobacteria is one of the most dominant and abundant phyla in soil,and was believed to have a wide range of metabolic and genetic functions. Relatively little is known about its community structure and elevational diversity patterns. We selected four elevation gradients from 1000 to 2800 m with typical vegetation types of the northern slope of Shennongjia Mountain in central China. The vegetation types were evergreen broadleaved forest,deciduous broadleaved forest,coniferous forest and sub-alpine shrubs. We analyzed the soil acidobacterial community composition,elevational patterns and the relationship between Acidobacteria subdivisions and soil enzyme activities by using the 16 S rRNA meta-sequencing technique and multivariate statistical analysis. The result found that 19 known subdivisions as well as an unclassified phylotype were presented in these forest sites,and Subdivision 6 has the highest number of detectable operational taxonomic units(OTUs). A significant single peak distribution pattern(P < 0.05) between the OTU number and the elevation was observed. The Jaccard and Bray–Curtis index analysis showed that the soil Acidobacteria compositional similarity significantly decreased(P < 0.01) with the increase in elevation distance. Mantel test analysis showed the most of the soil Acidobacteria subdivisions had the significant relationship(P < 0.01) with different soil enzymes. Therefore,soil Acidobacteria may be involved in different ecosystem functions in global elemental cycles. Partial Mantel tests and CCA analysis showed that soil pH,soil temperature and plant diversity may be the key factors in shaping the soil Acidobacterial community structure. | Yuguang Zhang Jing Cong Hui Lu Guangliang Li Yuanyuan Qu Xiujiang Su Jizhong Zhou Diqiang Li | 2014 | Journal of Environmental Sciences2014，26，8： | 17 |
| 2 | TEHL analysis of high-speed and heavy-load roller bearing with quasi-dynamic characteristics显示文摘In this paper, the aero-engine mainshaft roller bearing D1842926 under typical operating conditions is taken as a case study, a new integrated numerical algorithm of quasi-dynamics and thermal elastohydrodynamic lubrication(TEHL) is put forward, which can complete the bearing lubricated analysis from global dynamic performance to local TEHL state and break out of the traditional analysis way carried out independently in their own field.The 3-D film thickness distributions with different cases are given through integrated numerical algorithm, meanwhile the minimum film thickness of quasi-dynamic analysis, integrated numerical algorithm and testing are compared, which show that integrated numerical results have good agreements with the testing data, so the algorithm is demonstrated available and can judge the lubrication state more accurately.The parameter effects of operating and structure on pv value, cage sliding rate, TEHL film pressure, thickness and temperature are researched, which will provide an important theoretical basis for the structure design and optimization of aero-engine mainshaft roller bearing. | Shi Xiujiang Wang Liqin | 2015 | Chinese Journal of Aeronautics2015，28，4： | 3 |

| 13 | Growth Development and Reproductive Performance of Congjiang Fragrance Pig显示文摘[Objective] The paper was to determine whether the germplasm resources of Congjiang fragrance pig had changed over the past 30 years. [Method]The growth development and reproductive performance of 100 pigs from six towns in central fragrance pig producing area and Congjiang fragrance pig stock seed farm were measured,and further compared with the data in Guizhou Livestock and Poultry Breeds 1986. [Result]The growth and development status was basically consistent,and the average litter size was at a downward trend: the first litter decreased by 26. 2%; the second litter decreased by 7. 0%; the third litter decreased by8. 55%. [Conclusion] The study laid the foundation for vigorous promotion of Congjiang fragrance pig in industrial development process,acceleration of breeding pace,gradual updating of farming breeds by farmers and improvement of production efficiency of fragrance pig. | Shen Xuelin Duan Yongbang Yang Xiujiang Wei Shengquan | 2014 | Animal Husbandry and Feed Science2014，6，5： | 0 |
| 14 | Study on Habitat Forest Type and Plant Diversity of Sichuan Snub-nosed Monkey in Shennongjia National Nature Reserve显示文摘The experimental plots in representative areas of the Shennongjia Nature Reserve were established.The forest communities in Shennongjia were investigated by using TWINSPAN.The plant communities in these plots were investigated to discern the pattern of species diversity distribution along the altitudinal gradient.Theα-diversity andβ- diversity were calculated by using the data collected. Theα-diversity of the tree layer peaked in the evergreen broadleaved forest zone at low-elevation, theα-diversity of the shrub layer increased gradually at first and then decreased along the altitudinal gradient,while theα-diversity of the herb layer peaked in mid-altitude.Theβ-diversity peaked at mid-elevations where the composition of edificatory species changed.The transition zone was characterized by relatively high levels of species diversity and species turn-over rate.The overall species richness peaked in mid-altitude.The results of this research could provide a sound basis for reserve management and planning,as well as preservation of Sichuan snub-nosed monkey in this reserve. | Li Guangliang Xue Yadong Zhang Yuguang Su Xiujiang Yan Jingyuan Wang Xiulei Li Diqiang | 2012 | Chinese Forestry Science and Technology2012，11，3： | 0 |
| 15 | The Assembly of C60 in Semicrystalline PLLA Matrix显示文摘It has increasingly become a research focus to build higher structure composed of C60. However, there has been very few reports on the influence of polymer addition on the self-assembling behavior of fullerene in organic solvents. In this research, big needle-like C60 assemblings have been obtained in the form of PLLA/C60 composites. The largest C60 needles can be observed by naked eyes. The amount of C60 in the composite influences the length of C60 needles to some extent. DSC results indicate C60 accelerates the crystallization and lift the relative crystallinity of PLLA matrix. the results also imply the addition of semicrystalline PLLA influence the assembling behavior of C60. i.e., the crystallization of PLLA accelerated by C60 also act a driving force for the enriching and the linear assembling of C60 in PLLA matrix via Van der Waals force. | Li Chen Xiujiang Pang | 2012 | Nano-Micro Letters2012，4，1： | 0 |
