Paleogeographic analysis accounts for an essential part of geological research,making important contributions in the reconstruction of depositional environments and tectonic evolution histories(Ingalls et al.,2016;Merdith et al.,2017),the prediction of mineral resource distributions in continental sedimentary basins(Sun and Wang,2009),and the investigation of climate patterns and ecosystems(Cox,2016).

Journal of Earth Science 2022年

作者： Fangcui Liu Shengwen Qi shenglin Qi Xiaokun Hou Yanrong Li Guangming Luo lei Xue Xueliang Wang Juanjuan Sun Songfeng Guo Bowen Zheng Key Laboratory of Shale Gas and Geoengineering， Institute of Geology and Geophysics， Chinese Academy of Sciences University of Chinese Academy of Sciences Innovation Academy for Earth Science， CAS China-Pakistan Joint Research Center on Earth Sciences， CAS-HEC Government Affairs Service Center of Beijing Municipal Water Affairs Bureau Department of Earth Sciences and Engineering， Taiyuan University of Technology

The influence of different types of roots on the soil is complex and still remains unclear. Four in-situ extrusion tests were conducted on two types of root systems， namely fibrous and tap root system， for three plants (i.e. Eleusine indica， Potentilla anserine and Artemisia argyi)， according to the classification in Botany， and the thrust–displacement curves and failure patterns of different samples were analysed by comparison to fill the aforementioned gap. Results reveal that the roots can reduce the characteristics of soil brittleness and enhance its capability to resist large deformation， and different root types contribute different effects on the strain-hardening behaviour of the root–soil mass. The contribution of the fibrous root system on strength is limited， whilst the tap root system substantially enhances strength and stiffness. Results of failure patterns show that fibrous and tap root systems affect soil solidification and surface cracking reduction. However， the effect of the tap root system depends on the composition of lateral and tap roots: long and rich lateral roots are effective for resisting the creation of cracks， but thick tap roots with few and thin lateral roots may lead to several surface cracks.

采用二维非定常雷诺平均N-S方程和剪应力运输k-ω模型,结合四阶龙格-库塔法,选取4种不同入射角(α)对二自由度圆柱涡激振动响应影响进行数值研究。比较了不同来流角度下圆柱涡激振动幅值、结构振动频率、锁定区间、漩涡脱落模式、斯特劳哈尔数、水动力系数和捕能效率的影响。数值结果表明,来流角度变化会使圆柱涡激振动响应产生多频率特性,且随着来流角度的增加y方向振幅逐渐减小,x方向振幅逐渐增大。不同来流角度下涡激振动响应均产生明显的锁定现象,锁定区间宽度随来流角度的变化不明显。但随着来流角度的增加,y方向力系数均方根与x方向力系数均值均有下降的趋势。

相移轮廓术因其高精度和高鲁棒性广泛应用于三维重构。由于需投射多幅条纹图到物体表面,相移轮廓术要求物体在重构过程中保持静止,导致运动物体的三维重构精度较低。文中提出了一种基于相移轮廓术的双采样运动物体三维重构方法。首先调整相机和投影仪时序,使投影仪投射一幅条纹图的同时,相机完成两次采集。然后分析物体运动对双采样条纹图的影响,并建立条纹描述方程。结合物体的运动信息,提取混合相移条纹图中的相位信息。最终对拍摄条纹图进行复用,提高运动物体的三维重构帧率。实验结果表明,该方法不仅可以精确重构运动物体,减少运动误差,还在投影速度受限的前提下提高了运动物体的三维重构帧率。
