基于数字微镜器件(DMD)的无掩模光刻技术作为一种新兴技术在光刻领域备受关注,该技术利用DMD实现光刻掩模的数字化控制,为微纳米加工和快速原型制作提供了一种全新的解决方案。然而,在DMD无掩模光刻技术中还存在着一些问题,如投影畸变、像素化效应和邻近效应等,这些问题严重影响了光刻图形的精准性。本课题组基于多年的工作基础,全面分析了影响光刻图形质量的因素,并系统总结了几种提高光刻图案精准性的方法,包括数字掩模补偿法、像素叠加优化方法和飞秒局部修饰技术等。基于这些方法的相互配合,本课题组将投影畸变由37.7μm降低至1.7μm,将像素化效应降低为原来的1/6,将邻近效应造成的局部形变尺寸减小为1μm左右,制备出了高精准性的光刻图形。

Aluminum (Al) toxicity is a considerable factor limiting crop yield and biomass in acidic soil. Tartary buckwheatgrowing in acidic soil may suffer from Al poisoning. Here, we investigated the influence of Al stress on the growthof tartary buckwheat seedling roots, and the alleviation of Al stress by silicon (Si), as has been demonstrated inmany crops. Under Al stress, root growth (total root length, primary root length, root tips, root surface area, androot volume) was significantly inhibited, and Al and malondialdehyde (MDA) accumulated in the root tips. At thesame time, catalase (CAT) and ascorbate peroxidase activities, polyphenols, flavonoids, and 1,1-diphenyl-2-picrylhydrazyl(DPPH) and 2,2′-azinobis-(3-ethylbenzthiazoline-6-sulphonate) (ABTS) free-radical scavenging abilitywere significantly decreased. After the application of Si, root growth, Al accumulation, and oxidative damage wereimproved. Compared to Al-treated seedlings, the contents of ·O2− and MDA decreased by 29.39% and 25.22%,respectively. This was associated with Si-induced increases in peroxidase and CAT enzyme activity, flavonoidcompounds, and free-radical scavenging (DPPH and ABTS). The application of Si therefore has positive effectson Al toxicity in tartary buckwheat roots by reducing Al accumulation in the roots and maintaining oxidationhomeostasis.

什么是后人类?从人类到后人类,究竟意味着什么?当前流行的后人类主义概念,始源不同,涵义复杂:从人文科学的角度看,后人类(文)主义理论系从人文主义、反人文主义演化而来;从人机关系的角度看,智能机器的出现,使人类处于后人类境况,于是产生了后人类主义学说。一方面,人类越来越依赖机器;另一方面,智能机器越来越像人类。人机共存,共享世界,形成新的后人类共同体。当代(科幻)电影反映后人类处境,后人类理论用于电影研究,促进了新的共同体伦理与审美。

古人围绕韩愈是否有“选体”诗存在争议。从宋代至清代,“选体”概念自身的内涵存在变动,由指向汉魏五古向晋宋以下五古转移,其在五古一体中的诗史地位也由此发生升沉,进而影响了古人对于韩愈“选体”诗的判断。同时,韩诗自身在清代完成经典化,其“惟陈言之务去”的特性被清人树立为取法《文选》乃至所有前代经典的理想方式,也促成了韩诗与“选体”的剥离。古人对韩愈“选体”诗的揭示,提示了韩诗风格的多元性,也提示研究者在进行诗学研究时应注意诗学术语自身的流变。

《论语·述而》篇之“老彭”为谁，此为学术界之一大公案。或以为商朝时老彭，或以为尧时彭祖，或以为老聃与彭祖的合称，讫无定论。今依据文献，辨析诸说，结合语音变化规律，考定“彭”即“伯阳”之合音。人多以“伯阳”为老子的字，实则老子字“彭”,“彭”为鼓声，正与其名“李耳”义相关联，“伯阳”乃“彭”之音变。老子喜述古道，正同于孔子之“好古”。孔子之“述而不作”,“述”在于传承文化，“不作”则上通于老子之“无为”。

针对我国某型大功率重载机车在高原多曲线线路上运行时频繁出现轮缘裂纹的问题,采用理论分析、数值模拟与现场试验相结合的方法对机车轮缘裂纹损伤进行研究。首先,基于多体动力学和安定理论,建立了该型大功率重载机车车辆动力学模型及轮缘裂纹损伤预测模型:其次,通过现场测试数据与数值仿真结果对比,验证了模型的正确性;最后,根据该型重载机车运行线路特点,分析了曲线半径、曲线超高、曲线坡度等线路参数及轮缘润滑对重载机车轮缘裂纹损伤的影响规律。研究结果表明,连续小半径曲线是该型重载机车轮缘裂纹产生的主要原因,此外轮缘润滑对机车轮缘裂纹损伤有显著影响,可通过合理的线路参数设置及轮缘润滑来降低机车轮轨动态相互作用,进而减少重载机车轮缘裂纹的发生。
