调频连续波(FMCW)激光雷达具有非接触式测量、抗环境光干扰、高分辨率、能够同时获取速度和距离信息等优势,近年来被广泛应用于航空航天、精密制造、无人驾驶等领域。FMCW激光雷达的测距能力很大程度依赖于其光源的扫频线性度。在实际应用中,扫频光源会受到诸如应力拉伸不均匀、腔内温度变化、电路噪声等因素的影响,导致扫频非线性的产生,使得测距分辨率和精度下降。针对这一问题,本文从原理出发,分析了FMCW激光雷达中光源扫频非线性的影响,系统介绍了不同类型扫频非线性校正技术的原理和国内外研究进展,并对这些方法的适用场景、特性和优缺点进行总结,为后续相关研究提供启发。

为揭示不同施肥措施和土壤类型对我国西北地区典型农田土壤氮素矿化特征的影响,通过室内恒温好气培养法,分别研究不施肥(CK)、单施尿素(U)、单施有机肥(M)和尿素配施有机肥(U+M)施肥模式对土壤氮素矿化动态过程的影响,并对土壤累积矿化氮量进行一级动力学方程拟合及相关性分析。结果表明,施肥和土壤类型均显著影响土壤铵态氮含量、硝态氮含量和累积矿化氮量,且两者之间存在显著的交互作用。不同类型土壤累积矿化氮量和矿化速率由大到小依次为塿土、黄绵土、黄河灌淤土、灰棕漠土。与CK处理相比,不同施肥处理显著增加土壤累积矿化氮量、矿化速率常数(k)和矿化势(N0),处理间差异显著(P<0.05)。单施尿素和尿素配施有机肥处理的累积矿化氮量和矿化速率分别较CK处理增加2.83~6.71倍和3.83~7.70倍。相关分析表明,土壤累积矿化氮量与土壤有机质含量和全氮含量呈显著正相关关系。研究结果表明,有机无机肥配施处理可显著促进西北地区不同土壤类型氮素矿化,提高氮素有效性和供氮能力,有利于保持土壤矿质氮含量,对农田氮素高效利用有重要作用。

为了研究旁轴激光熔丝增材制造过程中,焊丝送入熔池的方位对沉积层成形的影响,进行了不同送丝角度和送丝方式下的单道激光熔丝沉积试验,分析对比了沉积层的层宽、层高、表面粗糙度、截面形貌和基板熔深随送丝角度和送丝方式的变化规律.结果表明,旁轴送丝的送丝角度和送丝方式对激光熔丝单道沉积层的成形都有一定影响,且送丝方式大于送丝角度对沉积层尺寸和形状的影响;随着送丝角度的增大,3种送丝方式的基板熔深都逐渐减小,前置送丝和后置送丝沉积层的层宽逐渐减小,层高逐渐增大,而侧置送丝沉积层的层宽、层高和表面粗糙度则变化较小;前置送丝和后置送丝沉积层的截面形状呈对称的圆弧形,侧置送丝沉积层的截面形状不对称,最高点偏向焊丝一侧.

本文使用2010—2021年A股上市公司样本,运用多期双重差分模型检验美国BIS施行的实体清单形式的出口管制政策对企业投资水平的影响及其作用机制。研究结果发现,实体清单政策显著抑制企业的投资水平并通过一系列的稳健性检验,在PSM-DID和工具变量回归分析中得到进一步证实;实体清单政策对非国有企业、高固定资产比例企业和高资本密集度企业的影响更大,主要通过削弱企业绩效、增加企业融资难度两个渠道影响企业的投资水平;实体清单政策风险显著降低同行业非受限企业的投资水平,而企业的绩效和融资约束的作用机制在实体清单政策风险的影响中仍然成立。最后,本文针对如何应对出口管制提出相应的政策建议。

文章使用2002~2013年中国海关数据库与中国工业企业数据库的匹配数据,实证分析了工业自动化对企业进口中间品质量的影响。文章的研究发现,工业自动化对企业进口中间品质量具有显著的正向影响,即存在显著的产品升级效应。异质性分析发现,工业自动化对进口中间品质量的产品升级效应仅发生在资本和技术密集型行业,而在劳动密集型行业中则体现为劳动替代效应。此外,企业在垄断行业以及所在地区营商环境越好,工业自动化对企业进口中间品质量的正向影响越大;与半成品相比,工业自动化更能促进企业进口原材料和零部件质量的提升。机制分析发现,工业自动化会通过创新效应、效率效应和产品质量效应提高企业进口中间品质量。文章进一步研究还发现,进口中间品质量的提升主要是由广延边际变化引起,而集约边际变化并不显著,且工业自动化与进口中间品质量存在联动效应,共同推动企业价值链地位的提升。文章从进口中间品质量角度丰富了工业自动化在企业升级转型中作用的研究,为中国更好地利用工业自动化的机遇提升企业价值链的地位提供了政策启示。
