大型民用飞机的机翼设计用于承受从大气阵风到湍流到着陆冲击的各种载荷,机翼是需要进一步研究的重要结构.改进机翼设计的主要方法之一是分析晃动对承载液体的柔性机翼状结构动力学的阻尼效应.这将通过开发实验装置来实现,该装置将有助于建立和再现涉及物理领域的数值模型.因此,本工作的目的是使用数值方法光滑粒子流体动力学(SPH)作为主要数值工具,分析晃动在降低飞机结构设计载荷方面的影响.本研究中的一个关键因素是对比例实验的需求,这是评估计算工具是否能够准确近似不同比例的注册测量值的必要步骤.为此,建立了一个垂直振动水槽的数值模型,该模型是一个完全耦合的流固耦合问题.该结构通过质量-弹簧-阻尼器系统建模,对于内部流体,使用δ-SPH方法.特别是,研究了两个开放性问题:第一个问题是,当储罐的初始加速度是标准重力值的十倍时,重力对阻尼和能量耗散现象的影响程度;第二种问题旨在确认,当根据量纲分析对问题参数进行缩放时,SPH方程正确地再现了缩放定律.

Compost Input Effect on Dryland Wheat and Forage Yields and Soil Quality

引用

Pedosphere 2018年第3期28卷 451-462页

作者： Francisco J. calderon Merle F. VIGIL Joseph BENJAMIN United States Department of Agriculture-Agricultural Research Service (USDA-ARS) Central Great Plains Research Station Akron80720 CO( USA)

Organic agricultural systems rely on organic amendments to achieve crop fertility requirements, and weed control must be achieved without synthetic herbicides. Our objective was to determine the crop yield and soil quality as affected by a transition from grass to dryland organic agriculture in the Central Great Plains of North America. This study evaluated three beef feedlot compost(BFC)treatments in 2010–2015 following biennial application rates: 0(control), 22.9, and 108.7 t ha^(-1) on two dryland organic cropping systems: a wheat(Triticum aestivum)-fallow(WF) rotation harvested for grain and a triticale(Triticosecale)/pea(Pisum sativum)-fallow(T/P-F) rotation harvested for forage. The triticale + pea biomass responded positively to the 108.7-t ha^(-1) BFC treatment,but not the 22.9-t ha^(-1) BFC treatment. The wheat biomass was not affected by BFC addition, but biomass N content *** feedlot compost input did not increase wheat grain yields, but had a positive effect on wheat grain Zn content. Soil total C and N contents increased with the rate of 108.7 t ha^(-1) BFC after three applications, but not with 22.9 t ha^(-1) BFC. Soil enzyme activities associated with N and C cycling responded positively to the 108.7-t ha^(-1) BFC treatment. Saturated salts were high in the soil receiving 108.7 t ha^(-1) of BFC, but did not affect crop yields. These results showed that BFC was effective in enhancing forage yields, wheat grain quality, and soil C and N, as well as specific microbial enzymes important for nutrient cycling. However, the large rates of BFC necessary to elicit these positive responses did not increase grain yields, and resulted in an excessive buildup of soil P.

On the Structure of Graded Leibniz Algebras

引用

Algebra Colloquium 2015年第1期22卷 83-96页

作者： Antonio J. calderon Martin Jose M. Sfinchez Delgado Departamento de Matemdticas Universidad de Cadiz 11510 Puerto Real Cadiz Spain

We study the structure of graded Leibniz algebras with arbitrary dimension and over an arbitrary base field K. We show that any of such algebras ￡ with a symmetric G-support is of the form ￡ = U-∑jIj with U a subspace of ￡1, the homogeneous component associated to the unit element 1 in G, and any Ij a well described graded ideal of ￡, satisfying [Ij, Ik]= 0 if j≠ k. In the case of ￡ being of maximal length, we characterize the gr-simplicity of the algebra in terms of connections in the support of the grading.
