| 1 | 环境温度和日粮锰对肉种鸡产蛋性能、蛋品质和血浆生化指标的影响显示文摘本试验旨在研究环境温度和日粮锰对肉种鸡产蛋性能、蛋品质和血浆生化指标的影响。试验采用双因素完全随机设计,包括2个环境温度(一个正常温度,21±1°C;一个高温,32±1°C)和3个不同的饲粮锰处理(在玉米-豆粕型基础日粮中添加0 mg/kg的锰、120 mg/kg的锰(来源分别为Mn SO4·H2O和蛋白锰)。因此,试验共6个处理组,每个组6个重复,每个重复4只鸡。结果表明高温降低了蛋重(P<0.0001)、产蛋率(P<0.0001)、产蛋量(P<0.0001)、采食量(P<0.0001)、饲料转化率(P<0.0001)、蛋壳强度(P<0.05)和蛋壳厚度(P<0.0001)、血浆三碘甲状腺氨酸水平(P<0.05)、碱性磷酸酶活性(P<0.04);提高了直肠温度(P<0.0001)、血浆丙二醛水平(P<0.02)、乳酸脱氢酶(P<0.002)、天冬氨酸转氨酶和肌酸激酶的活性。与不添加锰的饲粮相比,无论添加有机锰还是无机锰都增强了肉种鸡的蛋壳强度(P<0.05),降低了血浆三碘甲状腺氨酸和蛋白质羰基含量(P≤0.05)。与不添加锰的饲粮相比,饲喂添加有机锰日粮的肉种鸡的蛋壳厚度增加(P<0.01)。环境温度和饲粮锰在产蛋率、产蛋量、采食量和饲料转化率有相互作用(P<0.05)。在正常温度下,日粮无机锰或有机锰对产蛋率、产蛋量、采食量和饲料转化率不产生影响。然而,在高温情况下,饲喂有机锰日粮提高了肉种鸡产蛋率、产蛋量、采食量和饲料转化率(P<0.03)。本试验的结果表明:在32-45周龄,高温显著降低了产蛋性能、蛋壳质量,并诱导脂质过氧化反应和组织损伤。而日粮中添加有机锰或无机锰可以增加蛋壳强度和肉种鸡耐热性,并减少了蛋白质的氧化。综上,有机锰可以减轻高温对肉种鸡产蛋性能的负面影响。 | 樊倩 Y.W.Zhu J.J.Xie W.X.Li L.Lu L.Y.Zhang C.Ji X.Lin H.C.Liu J.Odle X.G.Luo | 2015 | 广东饲料2015，24，8： | 7 |
| 2 | 2008年汶川地震造成的应力变化和四川盆地地震危险性增加显示文摘2008年5月12日,灾难性的汶川7.9级大地震袭击了青藏高原东缘,造成四川盆地西部多个大城市房屋倒塌和大量人员伤亡。如此大的地震之后,地壳应力的重新调整通常会导致破坏性地震发生(Steinet al,1997;Stein,1999;McCloskey et al,2005;Parsonset al,2000;Parsons,2002)。5月12日地震的主震造成龙门山和四川盆地连接处最大位错量达9m,说明复杂的走滑和逆冲运动(Ji and Hayes,2008)为该地区的特征(Burchfiel et al,1995;Densmore et al,2007)。四川盆地及其周边也有其他活跃的走滑和逆冲断层相互交错。本文利用地震断层模型计算了由2008年5月12日汶川地震引起的同震应力变化,结果显示很多地区应力显著增加。快速给出这种应力变化图像有助于确定未来可能发生强余震的断层段。 | T.Parsons C.Ji E.Kirby 张效亮(译) 朱守彪(校) | 2009 | 世界地震译丛2009，40，1： | 4 |

| 6 | Turbulent flow simulation of a single-blade Magnus rotor显示文摘This paper presents numerical studies of the Magnus effect for a kinetic turbine on a horizontal axis.To focus on the Magnus blade,a single self-spinning cylindrical blade is assumed.An iterative direct-forcing immersed boundary method is employed within the Eulerian-Lagrangian framework due to its capability to treat complex and moving geometries.The Eulerian fluid domain is discretized using the finite volume method while the Magnus rotor is represented by a set of discrete points/markers.The aim of the numerical studies is to provide insights for the design process and predict aerodynamic performances under various operating conditions.Results for stationary and self-spinning cylinders in turbulent flows are found to be in good agreement with published data.By increasing the aspect ratio of the cylinder(simulated segment length over its diameter)from 3 to 10,a 30%drop in lift coefficient and a 22%increase in drag coefficient were observed,which is believed to be attributed to an enhancement of the three-dimensionality of the near-wake.For the Magnus rotor,key parameters such as dynamic forcing and frequency,distribution of pressure coefficient and torque have been produced for two cases with different structural designs and working conditions.With increase of the aspect ratio from 3 to 10,stable forces are observed from the root side of the blade and the torque coefficient increases from 0.68 to 2.1,which indicates a superior performance in terms of power extraction. | X.Bai C.Ji P.Grant N.Phillips U.Oza E.J.Avital J.J.R.Williams | 2021 | Advances in Aerodynamics2021，3，1： | 0 |
