摘要：分析了沙集闸站前池泥沙淤积成因,并试图改造在下游新建清污机桥,应用桥墩改善前池流态、减少泥沙淤积,采用三维建模软件UG NX建立河道流场三维模型,基于ICEM CFD进行计算域网格划分,并使用ANSYS CFX进行数值计算。计算结果表明:现状抽水工况下,导流墙内侧存在大范围低速区,因而产生大范围泥沙淤积。将泵站下游两侧导流墙延长至60 m,在导流墙头部新建清污机桥,应用桥墩导流,导流墙内侧低速淤积区范围大大减小,泵站进水流态大为改善。

摘要：信息流广告设计具有原生性要求,即广告与背景信息应相互融合。以往文献对原生性策略的探讨普遍基于劝说知识模型和图式理论,广告与背景信息的融合主要通过隐蔽广告披露和图式一致性来实现,很容易让信息受众产生被操纵感。本研究提出基于解释水平匹配的原生性策略,即通过广告信息的解释水平与背景信息启动的解释水平保持一致来实现融合。通过一项现场实验、一项预实验和三项模拟新闻资讯流的仿真实验,本研究揭示了媒体背景信息效价与广告时间框架在解释水平上的匹配效应及相应的中介机制和边界条件。研究发现:当背景新闻为积极正面(消极负面)时,采用长期(短期)框架来强调产品收益的信息流广告更有说服力;感知诊断性中介了上述匹配效应;时间约束调节了上述匹配效应。即当存在时间约束时,背景信息效价和广告时间框架的匹配对广告信息说服力的影响更强。

摘要：吐蕃统治晚期,敦煌石窟艺术依然以京洛文化为正统,受密教和波罗艺术影响,表现出融合与转折的特征。本时期石窟建筑形制和藻井纹样内容有向隋代和初唐回归的特征,莲花纹和三兔纹回归,与时代背景相呼应表现出“复古”特征。中唐晚期藻井中心莲花纹趋向收敛和拘谨,有别于初盛唐,正是中唐“低沉内敛”时代背景的体现。

摘要：自旋轨道矩磁性随机存储器(SOT-MRAM)作为第四代磁随机存储器广受关注。SOT-MRAM为三端结构,应用于2T2R结构时,不对称写入容易导致电荷积累,从而对读产生影响,甚至导致读取错误的发生。因此研究针对SOT-MRAM特点的读电路泄电结构,减小写入对读取通路的影响具有重要意义。本文针对SOT-MRAM写入不对称导致电荷积累问题,对比了两种泄电电路结构,有效降低了首个读周期的读取时间延迟。研究了引入的泄电结构对位线电容的容忍度的影响。分析了位线电容差异导致读取不对称的机理,结合首个读周期读取时间延迟问题,提出了适合SOT-MRAM特点的读取电路泄电结构。本文的研究为SOT-MRAM读取电路的设计提供了新思路。

摘要：Online video advertising using the English language is a trend in international marketing. While previous studies have pointed out that individuals＇ motivational orientation in the context of advertising plays a key role in ad preference and effectiveness, few studies have been carried out to investigate the effect of online English advertising on international consumers with different motivational orientations in non-English speaking populations Accordingly, this article examines the effects of motivational orientation and brand familiarity on positive emotions and skepticism in international consumers＇ responses to online video English advertising. The results imply that participants＇ positive emotions can be influenced more by their motivational orientation than by their familiarity with the brand, while their skepticism can be affected more by brand familiarity than by motivational orientation toward the ad. Moreover, participants high in English promotion orientation displayed higher positive emotions toward unfamiliar brand online advertising than did the English prevention-orientated participants toward a familiar brand ad. Prevention orientation exhibits a higher level of skepticism towards an unfamiliar brand online video advertisement. The effects are more explicit in motivational orientation in English than general motivational orientation. This research suggests that generating positive emotions and reducing the skepticism of non-English-speaking individuals is essential to build brand image in online marketing.

摘要：研究由乙烯、丁烯和亚乙基降冰片烯为单体,茂金属催化合成的新型三元乙丙橡胶(EBT EPDM)和通用三元乙丙橡胶(EPDM)的耐低温性能以及炭黑种类对EBT EPDM胶料耐低温性能的影响。结果表明:与EPDM胶料相比,EBT EPDM胶料的t_(10)和t_(90)均缩短,F_(max)-FL增大;EBT EPDM硫化胶在低温条件(-40℃×72 h)下的压缩永久变形减小71.5%,脆性温度降低37.7%,低温回缩温度TR10最低,低温弯曲后表面未出现裂纹,耐低温性能优异;随着炭黑粒径的增大,EBT EPDM硫化胶的低温压缩永久变形减小,脆性温度降低;在相同低温条件下,EBT EPDM硫化胶的压缩永久变形与硅橡胶硫化胶相近,但EBT EPDM价格远低于硅橡胶,可拓宽其在低温密封领域的应用。
