Soil structure plays an important role in edaphic conditions and the environment. In this study, we investigated the effects of organic amendment on soil structure and hydraulic properties. A corn field in a semiarid land was separately amended with sheep manure compost at five different rates (2, 4, 6, 8 and 10 t/ha) and corn stover (6 t/ha) in combination with two decomposing agents. The soil structure of different amended soils was analyzed from the aggregate and pore domain perspectives. The internal pore structure of the soil was visualized through X-ray computed tomography and quantified using a pore-network model. Soil aggregate-size distribution and stability, saturated hydraulic conductivity, and water-retention curves were measured by sampling or in situ. The gas permeability and diffusivity of different amended soils were simulated based on the extracted pore networks. The aggregate stability of the amended soils was improved compared with the control, that is, the mean weight diameter increased and the percentage of aggregate destruction decreased. The stability of soil aggregates varied non-monotonically with the application rate of compost and decreased after treatment with corn stover and decomposing agents. The pore-network parameters including air-filled porosity, pore radius, throat length, and coordinate number increased for the amended soils compared with the control. The mean pore size increased with increasing compost incorporation rate. The saturated hydraulic conductivity of the compost-amended soils was higher than that of the control but varied quadratically with the application rate. The saturated hydraulic conductivity of soil treated with corn stover and decomposing agents was clearly higher than that without the agent and the control. The greater gas diffusivity and air permeability indicate that soil aeration improved following the incorporation of organic amendments. The air permeability versus air-filled porosity relationship followe

图像匹配的目标是从两个或多个图像中找到相似结构之间对应关系的算法，是计算机视觉领域中的基础且重要的问题，在机器人、遥感、自动驾驶等领域具有广泛应用。近年来随着深度学习的发展，基于深度学习的二维匹配算法在特征提取、特征描述以及特征匹配三方面不断进行改进，其性能在匹配精度、鲁棒性等方面远超传统算法，取得了丰硕的成果。尽管目前已存在大量关于二维图像匹配算法的综述，但是仍缺少对最新图像匹配算法发展的归纳。因此，对计算机视觉领域的二维图像匹配任务近八年基于深度学习特征的二维匹配方法进行总结，从基于局部特征的检测和描述的双阶段匹配方法、基于联合特征检测和描述的匹配方法和无特征检测的匹配方法三方面详细介绍了二维图像匹配算法的发展过程、分类方法、性能评价指标，并对各类方法的优点及局限性进行归纳。然后，对二维图像匹配算法的应用场景进行介绍，阐述了二维图像匹配的进展对其应用领域的影响。最后，对二维图像匹配算法的发展趋势进行总结和展望。

在由单个制造商和单个零售商构成的低碳供应链中,制造商与零售商之间不同的权力结构决定着他们的减排策略与博弈方式.同时,低碳产品商誉与需求受到制造商与零售商减排策略及随机因素的长期动态影响.在不同的权力结构下,对制造商减排努力策略与零售商宣传努力策略进行随机微分博弈分析;在集中式决策基础上,分别构建制造商主导与零售商主导的Stackelberg博弈、无主导Nash博弈模型,求解模型并对结果进行理论分析与数值实验.研究发现:相较于自己作为主导者,对方作为主导者会促使制造商或零售商做出更大的减排努力或宣传努力;与有主导者的供应链相比,无主导者的供应链可能实现更大的低碳产品商誉;制造商作为主导者能够提升低碳产品商誉与需求以及供应链总利润.随机因素促使制造商和零售商分别提高了减排努力和宣传努力以及低碳产品商誉.
