摘要：在挖掘古建彩画的文化内涵基础之上,对旋子彩画的元素、构图形式和色彩特征进行归纳与分析,通过再设计将其辐射到文化衍生品的领域上,例如运用到钥匙扣、旋子手账模具、学生直尺套装的日常用品中。通过设计实践试图探索用设计创新的方式将优秀的传统文化转化成为现代年轻人所接受的形式,并让古建彩画可持续性发展。通过古建彩画衍生品的活化和推广的可行性尝试,提出衍生品开发的两种建议:一是与产品设计师结合,为特定的主题提供唯一的文创产品;二是文创产品要符合现代人的美学标准和生活场景。文章以旋子彩画图案为切入点,实践研究传统古建彩画如何与现代生活应用品相结合的应用,探讨传统古建彩画在现代设计的延伸和拓展形式,探究传统艺术年轻化的可能性,为后人研究提供参考依据。

摘要：Developing efficient electrocatalysts for the oxygen evolution reaction(OER)under neutral conditions is important for microbial electrolysis cells(MECs).However,the OER kinetics in neutral electrolytes at present are extremely sluggish,resulting in high overpotentials that greatly limit the energy conversion efficiencies of *** studies failed to probe the adsorbates on surface metal sites of catalysts at the atomic scale and elucidate their influence on the catalytic activities,which has impeded the rational design of efficient neutral OER catalysts with optimal surface ***,using in situ transmission electron microscopy(TEM),in situ X-ray photoelectron spectroscopy(XPS)and in situ low-energy ion scattering studies,we have identified,for the first time,that the electrochemically activated adsorbates on surface metal sites play a critical role in boosting the neutral OER activities of Ru-Ir binary oxide(RuxIryO2)*** adsorbate-activated RuxIryO2on a glassy carbon electrode achieved a low overpotential of 324 m V at10 m A cm-2in neutral electrolyte,with a 36-fold improvement in turnover frequency compared with that of Ir *** application in an MEC system,the resulting full cell showed a decreased voltage of 1.8 V,200 m V lower than the best value reported to date,facilitating efficient synthesis of poly(3-hydroxybutyrate)from bioelectrochemical *** functional theory(DFT)studies revealed that the enhanced OER activity of RuxIryO2catalyst arose from local structural distortion of adjacent adsorbate-covered Ru octahedra at the catalyst surface and the consequently decreased adsorption energies of OER intermediates on Ir active center.

摘要：红外视频存在颜色信息缺失较为严重、识别区域易与背景混淆等现象,使得现有小样本特征提取网络常常关注无效信息,导致识别精度较低。针对此问题,本文提出一种基于内卷积(Conv-Involution)算子的红外视频小样本人体行为识别方法。首先,通过InstColorization方法恢复红外视频中的颜色信息;其次,基于空间和通道特异性设计Conv-Involution算子,并利用该算子和改进注意力机制设计特征提取网络,分离背景,更有效地关注行为发生区域;最后,结合小样本学习方法ANIL进行人体行为分类。对比实验结果表明,本文所提方法不但识别精度最高,而且具有出色的稳定性。

摘要：在煤化工领域中,煤气化是十分重要的一项技术,也是煤制油、甲醇、天然气等煤炭深加工的基础工艺。在碎煤固定床加压气化生产当中,酚氨回收装置脱酸脱氨塔塔釜液水质超标等问题,需要不断对脱酸脱氨塔进行优化设计,保证煤深加工的质量以及环保性。基于此,本文重点探究煤气化废水酚氨回收装置中,脱酸脱氨塔的优化操作。

摘要：Because ring-stiffened cylindrical shell structures have many merits, they are widely used in many areas. However, as the strength of steel increase continuously, ensuring of the structure stability is becoming more and more important. Therefore, it is necessary to carry on a more particular analysis. Based on the understanding and analysis of the characteristics of stability for a ring-stiffened cylindrical shell under uniform external pressure and under external single pressure, the characteristics under different cross uniform external pressures are analyzed, and the regularity of it is also gotten. The curve of stability given various geometrical parameters under different cross uniform external pressures is protracted by the analysis of the theory. The conclusion not only improves the theory structural mechanics, it also was important effects on engineering calculation and design.

摘要：以真实城市供水管网监测数据为研究对象,构建了ARIMA模型和SVR模型2种典型的时间序列预测模型。在正常和发生爆管2种不同工况下分别基于历史数据进行预测。对预测结果进行对比分析得到,ARIMA模型和SVR模型在正常工况下的精度相近,但SVR模型在爆管发生时的预测结果能产生更大的残差,相较于ARIMA模型更适合于数据驱动的爆管识别方法。

摘要：目的分析血清微小核糖核酸(miR)-18a、miR-92a水平与宫颈癌患者淋巴结转移的关系。方法选取2018年1月至2020年1月西安市人民医院收治的78例宫颈癌患者作为研究对象。评估所有患者入院时淋巴结转移发生情况,并分为转移组与未转移组。设计基线资料调查表,统计两组基线资料,重点分析入院时血清miR-18a、miR-92a水平与宫颈癌患者淋巴结转移的关系。结果78例宫颈癌患者发生淋巴结转移16例,占比20.51%;转移组与未转移组的血清miR-18a、miR-92a水平比较,差异具有统计学意义(P0.05);Logistic回归分析结果显示,入院时血清miR-18a、miR-92a异常表达可能与宫颈癌患者淋巴结转移有关,两者过表达可能是宫颈癌患者淋巴结转移的风险因子(OR>1,P0.80,评估价值均理想,且以联合评估的价值最高。结论入院时血清miR-18a、miR-92a过表达可能与宫颈癌患者淋巴结转移有关。
