Root carbon consumption and grain yield of spring wheat in response to phosphorus supply under two water regimes

引用

Journal of Integrative Agriculture 2016年第7期15卷 1595-1601页

作者： guan Yu qiao zhen DU Jiu-yuan DU Yan-lei Department of Resource and Environmental Science Agronomy College Shihezi University State Key Laboratory of Grassland Agro-ecosystem Institute of Arid Agroecology School of Life Sciences Lanzhou University Institute of Wheat Gansu Academy of Agricultural Sciences

In semiarid areas, cereal crops often alocate more biomass to root at the expense of aboveground yield. A pot experiment was conducted to investigate carbon consumption of roots and its impact on grain yield of spring wheat （Triticum aestivum L.） as affected by water and phosphorus （P） supply. A factorial design was used with six treatments namely two water regimes （at 80–75% and 50–45% ifeld capacity （FC）） and three P supply rates （P1=0, P2=44 and P3=109 μg P g–1 soil）. At shooting and lfowering stages, root respiration and carbon consumption increased with the elevate of P supply rates, regardless of water conditions, which achieved the minimum and maximum at P1 under 50–45% FC and P3 under 80–75% FC, respectively. However, total aboveground biomass and grain yield were higher at P2 under 80–75% FC; and decreased with high P application （P3）. The results indicated that rational or low P supply （80–75% of ifeld water capacity and 44 mg P kg–1 soil） should be recommended to improve grain yield by decreasing root carbon consumption in semiarid areas.

Generalization of an elementary inequality in Fourier analysis

Applied Mathematics(A Journal of Chinese Universities) 2010年第1期25卷 43-47页

作者： ZHOU guan-zhen Faculty of Statistics and Mathematics Zhejiang Gongshang University Hangzhou 310018 China

The inequality sup n≥1｜n∑k=1 sinkx/k｜≤3√π,plays an important role in Fourier analysis and approximation theory. It has recently been generalized by Telyakovskii and Leindler. This paper further generalizes and improves their results by introducing a new class of sequences called γ-piecewise bounded variation sequence （γ-PBVS）.

Electroless plating of copper layer on surfaces of urea-formaldehyde microcapsule particles containing paraffin for low infrared emissivity

引用

Particuology 2016年第1期14卷 159-163页

作者： Xi Zhou Jian Mao zhen qiao College of Materials Science and Engineering Sichuan University No. 24 South Section 1 Yihuan Road. Chengdu 610064 Sichuan China

A copper coating was deposited by electroless plating on the surfaces of urea-formaldehyde microcap- sules containing paraffin （UFP） particles. This composite microcapsule structure had low infrared OR） emissivity and maintained a constant temperature, and could be used in IR stealth applications. The eiectroless copper layer formation and its micro-appearance, and the effect of the copper layer on the IR emissivity and thermal properties of the composite microcapsules were investigated. The IR emissivity of the composite microcapsules at wavelengths of 1-14 μm gradually decreased with increasing copper mass on the surface. After formation of an integrated copper layer, the rate of IR emissivity decrease was lower. This is because the copper coating improves the surface conductivity of the UFP; a high conductivity results in high reflectivity, which leads to a decrease in IR emissivity. The lowest IR emissivity achieved was 0.68. The phase-change enthalpy of the composite microcapsules decreased with increasing amount of copper coated on the surface because of the high density of copper. When the mass increase of the UFP after electroless copper plating was about 300%, the composite microcapsules had low IR emissivity （about 0.8） and a high phase-change enthalpy （80J/g）.
