本研究题目的选择是基于象征主义手法在乔伊斯早期文学创作中的重要性。《都柏林人》是乔伊斯早期文学创作的代表作。除了《死者》，剩下的三篇短篇故事－《会议室的常青藤日》、《母亲》和《圣恩》都被国内学者研究的较少。本文主要从物品象征、背景象征和人物象征三方面分析研究以上四篇短篇故事。大多数的物品都是老旧的。几乎所有的背景设定都是阴暗的。许多人物要不就是老去的，要不就是已经去世的。这些人物的生活方式也都是堕落的。研究结果表明，通过象征主义的运用，乔伊斯成功的强化了《都柏林人》的主题－堕落。乔伊斯匠心独运的选择了小件的物品、设定了阴郁的背景、并且描绘了都柏林人腐败的生活方式来体现都柏林的堕落。

The experiments were performed to investigate the degradation of microcystins in order to assess the effectiveness and feasibility of UV/H2O2 system for the disinfection of water polluted by microcystins. The influence factors such as H2O2, pH and UV light intensities were investigated respectively. Degradation of microcystin-RR （MC-RR） could be fitted by either the pseudo-first-order or second-order rate equations. This homogenous system could significantly enhance the degradation rate due to the synergetic effect between UV and H2O2. The degradation mainly followed the mechanism of direct photolysis and .OH oxidation reactions. Experimental results showed that 94.83% of MC-RR was removed under optimal experimental conditions and the UV/H2O2 system provided an alternative to promote the removal of microcystins in drinking water supplies.

背景:虚拟现实技术是近年来较为热门的一项人机智能交互技术,已被广泛应用于休闲娱乐、职业培训及医疗康复等领域。目的:旨在探索虚拟现实技术与不同疗法联合在周围神经损伤患者功能恢复中的潜力,概述其作用机制,评估其应用效果和前景,探讨其优势和不足之处,为周围神经损伤后的康复实践提供新的思路和方法。方法:应用计算机检索中国知网、Pub Med数据库建库时间至2024年5月期间的相关文献,英文检索词为“peripheral nerves injury,virtual reality,endoplasmic reticulum stress,muscle atrophy,cerebral cortex,mirror therapy,tendon vibration,treadmill training”,中文检索词为“周围神经损伤,虚拟现实,内质网应激,肌肉萎缩,大脑皮质,镜像疗法,肌腱振动,跑步机训练”,最终纳入68篇文献进行分析。结果与结论:(1)虚拟现实技术作为一种新兴的辅助手段,通过模拟真实环境为患者提供沉浸式的多感官体验,不仅极大地丰富了康复训练的维度,还显著加速了周围神经损伤患者功能恢复进程;虚拟现实技术的作用机制是通过多感官刺激促进皮质可塑性,相邻的皮质区域入侵沉寂区,这些区域对其他输入作出反应或产生新的肌肉激活,从而促进功能恢复。(2)虚拟现实技术已与传统疗法广泛联合,展现出其独特优势。与镜像疗法联合时,虚拟现实的优势是打破了体位的限制,提前康复介入时间点;与肌腱振动联合,虚拟现实技术通过增强视觉和触觉的双重刺激增强运动错觉,显著提高患者的感知和运动能力,但也存在增加对肢体重量感知的问题;与跑步机训练联合,虚拟现实技术进一步发挥其优势,通过多感官刺激模拟现实环境进行平衡和步行功能,但晕动症等问题依旧存在。(3)因此,在实际应用中,由于虚拟现实与镜像疗法、肌腱振动联合都会增强患者运动错觉,更适用于康复早期,而虚拟现实与跑步机训练联合则适用于康复后期,帮助患者更好地回归日常生活。(4)尽管虚拟现实技术在周围神经损伤康复中已经显示出巨大的潜力,但仍存在一些问题和挑战,如晕动症、虚拟现实康复游戏的设计与应用,以及伦理方面的考量,未来的研究应着重解决这些问题,以推动虚拟现实技术在康复领域的进一步发展。

Amorphous Ni-Ru-B/ZrO2 catalyst was prepared by the means of chemical reduction, and selective CO methanation as a strategy for CO removal in fuel processing applications was investigated over the amorphous Ni-Ru-B/ZrO2 catalyst. The result showed that, at the temperature of 210-230 ℃, the catalyst was shown to be capable of reducing CO in a hydrogen-rich reformate to less than 10 ppm, while keeping the CO2 conversion below 1.55% and the hydrogen consumption below 6.50%. ？2009 Xin Fa Dong.

Advances in Manufacturing 2014年第1期2卷 3-12页

作者： qi-Jie Zhao Peng Cao Da-Wei Tu School of Mechatronics Engineering and Automation Shanghai Key Laboratory of Intelligent Manufacturing and RoboticsShanghai university

Correctly coding materials and identifying characters marked on materials are very important for steel manufacturing industry to realize informatization management and intelligent manufacturing. However, the steel products manufacturing is often in a high temperature environment, and there are a lot of material storage and retrieval processes, workers are not easily close to the environment and complete tasks, so it is a great challenge to automatically mark and identify characters on the steel products. This paper presents a framework of label characters marking and management for steel materials, furthermore, a kind of marked characters online detection and tracking method has been provided based on machine vision. In addition, some experiments have been done in BaoSteel to mark characters on hot billets and recognize them in multi situations, and the results show that the proposed method is practical, and has provided a helpful exploration in obtaining accurate fundamental data for the intelligent manufacturing system in steelworks.
