Abstract: 本试验旨在研究妊娠后期和泌乳期饲粮添加姜粉对母猪和哺乳仔猪抗氧化性能的影响。试验采用2×2析因试验设计,分2个饲养阶段(妊娠后期和泌乳期)进行,每个饲养阶段设2个姜粉添加水平(0、1.0%)。结果表明,在妊娠后期饲粮中添加姜粉,显著提高了母猪血清中超氧化物歧化酶(SOD)活性、总抗氧化能力(T-AOC)和谷胱甘肽(GSH)含量,降低了母猪血清中丙二醛(MDA)含量(P<0.05);在泌乳期饲粮中添加姜粉,显著提高了母猪血清和乳中SOD活性、T-AOC和GSH含量(P<0.05);而在妊娠后期和泌乳期饲粮中分别单独添加姜粉时,均显著提高了仔猪血清GSH含量(P<0.05)。2个时期均添加姜粉对母猪血清、母乳和仔猪血清抗氧化效果最佳。由此可见,在妊娠后期和泌乳期饲粮中添加1.0%姜粉均能够提高母猪和哺乳仔猪的抗氧化性能,且2个阶段不存在交互作用,在妊娠后期和泌乳期同时添加时效果最好。

Abstract: 合理分析气候变化和人类活动对河川径流的影响,是环境变化影响研究领域中的科学问题,由于现阶段气候变化和剧烈的人类活动,致使径流形成机理和规律发生了变化。本文提出了在采用统计学方法分析径流和降水变异分析的基础上,将径流分成基准期和变化期,以基准期为基础建立降水径流双累积曲线模型,定量分析变化期气候变化和人类活动对径流的影响。以汾河流域为例进行了实例研究,研究结果表明,汾河入黄河津站实测径流减少趋势明显,1981年为径流的突变年份。1981年后气候变化和人类活动的综合作用致使实测径流减少明显。其中,人类活动致使径流深减少了13.0 mm,贡献率为84.4%,降水减少致使径流深减少了2.4 mm,贡献率为15.6%
Reasonable analysis on influences of climate change and human activities on runoff is a scientific question of environmental changes. Runoff generation mechanism and rules has changed due to the climate change and intense human activities. Double Mass Curve method was built based on the baseline period to quantify the influence of climate change and human activities on runoff according to the statistics results. The Fenhe river basin was chosen as case study. The results show that the runoff of the Fenhe river basin had a decreasing trend, and the mutation year is 1981. The reasons of observed runoff reducing caused by combined effect of climate change and human activities after 1981. The affect amounts of runoff are 15.4 mm, in which 13.0 mm is caused by the human activities and 2.4 mm is caused by climate change, the contribution

Abstract: 本文基于长江流域宜昌站1882~2007年径流量资料,通过径流旱涝急转指数和轮次分析法,分析了长江流域宜昌站径流旱涝急转现象和极端枯水情况,研究结果表明长周期径流旱涝急转在 1950年以前发生次数较多,而1950年以后发生次数相对较少;除下1985年涝转旱额外显著外,从1951~2007年旱涝转化现象相对于1951年之前有平稳的趋势。极端枯水总量总体呈增加趋势,到70年代达到最大,并且主要发生时段为1~4月的非汛期。极端枯水事件总体呈增加趋势,到70年代达到最多。极端枯水总量与发生次数同步性并不突出。利用不同百分位值分析

Abstract: 对于以超声波为载体的生物医学声学成像(如超声、光声和磁声成像等)技术,为了简化问题,常在假设待测组织内声速恒定的前提下,重建组织内的声阻抗、光吸收分布、光学特性参数分布或者电导率分布等。但是,实际生物组织内部的声速是存在差异的(最大可达10%),因而在此假设前提下重建出的图像通常是不准确的。在介绍声速不均匀性对声学图像重建影响的基础上,对超声、光声和磁声成像中解决声速不均匀问题的主要方法,特别是光声层析成像中重建组织内声速分布的主要方法进行总结和归纳,讨论各自的优点和不足,并展望未来的可能发展方向。
For the ultrasound based biological imaging techniques, such as ultrasonic imaging, photo acoustic tomography (PAT) and magneto acoustic tomography (MAT), the spatial distribution of acoustic impedance, light absorption, optical parameters or electrical conductivity in the imaging tissue is always reconstructed under the assumption of a constant speed of sound (SOS) in tissues. However, the actual difference of SOS in different biological tissues may be up to 10%. This paper reviews the current methods to solve the problem of SOS inhomogeneity based on a brief introduction to the influence of SOS inhomogeneity on acoustic image reconstruction. Especially, the methods of restoring the distribution of SOS in the target tissue in PAT are overviewed including their advantages and disadvantages. Possible improvement in the future is also forecasted.
