大陆中、下地壳切向(近水平)分层固态流动变形是地壳物质流动的重要形式之一,也是片麻岩穹隆的重要形成机制。雅拉香波穹隆位于特提斯喜马拉雅构造带的最东段,出露不同变质级别和时代的岩石地层,发育强烈的韧性剪切变形以及多期岩浆事件,是研究造山过程中构造变形和岩浆历史的天然实验室。本文以该穹隆为研究对象,进行了详细的野外构造解析和显微观察等工作,总结出以下三个特点:(1)雅拉香波穹隆内不同构造层次的岩石经历了相同的构造体制和不同变形条件改造:从浅部到深部,变形温度逐渐递增,由390℃到600℃;差应力逐渐减小,从24.58MPa减少至8.72MPa;应变速率逐渐加快,从1.27×10^(-13)~1.28×10^(-13)/s增加到5.19×10^(-11)~5.21×10^(-11)/s。以上体现了地壳活动带强烈的分层流变特点。(2)结合前人研究划分了穹隆变形的三个期次(D_(1)、D_(2)和D_(3)),其中D_(1)表现为上盘向南的剪切方向,D_(2)则表现为上盘向北的剪切方向。进一步,将主要变形期次D_(2)进一步划分为两个阶段,早期主要是以单剪为主导的剪切作用类型,而晚期则是以纯剪为主导的剪切作用类型。(3)根据D_(2)面理和线理的产状分布特点,可以得出,深部岩石线理的倾伏角近水平,而浅层次岩石的线理倾伏角近竖直。基于以上研究表明,雅拉香波穹隆各部分岩石均遭受了不同程度的剪切改造,不同构造层次的岩石具有几何学上的一致性以及运动学上的解耦,体现了穹隆发育过程中运动方向上的转变。结合穹隆各部位线理的倾伏角的变化规律,本文认为雅拉香波穹隆记录了中下地壳分层流动的过程,穹隆的形成主要受中下地壳近水平切向流动控制,辅以垂向流动的改造。

针对无人机视觉下图像背景复杂、目标过小导致的检测效果过差的问题,提出了一种基于YOLOv5的改进算法。首先,提出滤波分离特征提取(FSFE)结构,将滤波分离后的图像与原图像并行输入神经网络进行特征提取,加强了网络对全局和细节的重要信息的提取,将输出特征图进行空间自适应融合,防止了融合时的语义信息割裂的问题,并且使得网络能够更加关注关键层的信息。其次,增加小目标检测层,并利用了SPD卷积模块加强特征学习来提高检测性能。最后,在C3模块中镶嵌CA特征增强模块,在特征提取时挖掘并保存重要的语义信息。基于VisDrone2019数据集的实验结果表明,改进算法的mAP@0.5和mAP@0.5∶0.95分别提升了8.3和6.1个百分点,精确率和召回率分别提升了5.1和4.5个百分点,提升了小目标检测精度,同时减少了漏检、误检概率,对实现无人机视觉小目标检测有重要意义。

Large-scale Patterning of Hydrophobic Silicon Nanostructure Arrays Fabricated by Dual Lithography and Deep Reactive Ion Etching

引用

Nano-Micro Letters 2013年第1期5卷 7-12页

作者： Zhibo Ma chengyu jiang Weizheng Yuan Yang He Key Laboratory of Micro/Nano Systems for Aerospace Ministry of EducationNorthwestern Polytechnical University

We describe a simple but efficient technique to fabricate large-scale arrays of highly ordered silicon nanostructures. By coupling dual lithography using light of 351.1 nm wavelength with deep reactive ion etching(DRIE), silicon nanostructures of excellent regularity and uniform coverage were achieved. The proposed nanofabrication method not only simplified the nanofabrication process but also produced highaspect-ratio(higher than 15) nanostructures. The scalloping problem was also controlled by regulating DRIE parameters. The process is rapid, cheap, examined to optimize the fabrication process, and has the potential to be scaled up to large areas. The contact angle of a water droplet atop the surface is larger than 150?.Moreover, by coupling black silicon process with DRIE-based microfabrication, three-dimensional nano/nano dual-scale structures which show robust and stable hydrophobicity have been achieved. This process opens new application possibilities in optical, photoelectric, microelectronic, catalytic and biomedical applications.

为解决贵州某矿采空区自然发火早期精准预测预报的难题,以该矿12501工作面采空区为研究对象,利用程序升温实验重点分析煤样在升温氧化过程中CO、CO_(2)、C_(2)H_(4)、C_(2)H_(6)等气体的变化规律,通过数值模拟及现场实测对采空区自燃“三带”进行了划分。结果表明:CO、C_(2)H_(4)、C_(2)H_(2)可作为自然发火标志气体,C_(2)H_(4)/C_(2)H_(6)可作为判别煤自然发火进程的辅助指标;散热带平均宽度约18 m,氧化带平均宽度约53 m,氧化带以外为窒息带;当采煤工作面的推进速度大于0.53 m/d时,采空区无自然发火危险;当工作面连续超过114 d时,推进速度均小于0.53 m/d,采空区将有自然发火危险。研究结果为贵州某矿煤层自燃预报提供了理论依据及数据参考,对防治煤层自燃具有重要意义。
