阿拉善右旗哈托哈拉金矿区位于内蒙古自治区阿拉善右旗北东方向120 km处,矿区矿体主要赋存于早二叠世和晚石炭世侵入岩内,受北东向韧脆性断裂控制,沿断裂带可见长英质糜棱岩及条带状石英脉发育,其内可见较强的硅化、绢云母化、绢英岩化、绿泥石化、褐铁矿化及碳酸盐化等矿化蚀变发育。本文较详细地阐述了该区地质背景和矿区地质特征,总结了矿区找矿标志,为下一步找矿提供了借鉴。 相似文献

Given that banner ad investment is huge and keeps increasing, the effectiveness of banners is important for advertising practitioners and is worth attention from academics. Banner properties (e.g. format and animation) may influence the overall effectiveness of banners. However, research on how banner formats (e.g. location and orientation) affect banner effectiveness is still in its early stage and studies on how animation influences banner effectiveness have also found controversial results. By conducting an experiment using eye-tracking technology, this study investigated the impacts of banner properties, especially animation speed and format, on users' attention, recall, and attitudes towards banners. In terms of attention, both the main effects and the interaction effect were significant and the patterns varied across time. However, no significant effects were found on recall and attitudes. 相似文献

本文在分析现有网络广告研究的基础上,尝试进行网络广告的数字研究。在收集实际调研数据的基础上,对网络广告现阶段的一些现象和特征进行数字化,并采用横向、纵向的类比法对这些现象和特征进行定量分析研究。笔者在选定的时间内,选择国内具有代表性的网站,每天于固定时段抓取这些站点中固定页面上的横幅广告和弹出式广告,共抽取样本二百余条,分别对这些广告的行业分类,技术分类,品牌标志的使用情况、人物、产品图片和文案的使用情况,互动功能的使用情况等进行分类统计,并在此分类统计的基础上进行分析研究。 相似文献

We develop and describe a framework for research in a particular segment of digital advertising. Internet Advertising Paid Slots and Spaces (IAPS) is a neologism and work almost like a stock exchange for buying and selling advertising in various formats on designated spaces around web and make a significant contribution to Internet advertising revenues. These paid spaces were found to encompass diverse areas of Internet advertising that include search engine marketing, social media advertising and display advertising. Given the complexity of the modern digital advertising eco system, this literature review seeks to provide clarity, up-to-date knowledge and ongoing insights into Internet advertising channels, for managers making investment decisions in this context. 相似文献

Previous findings suggested that banner ads have little or no impact on perceptual behavior and memory performance in search tasks, but only in browsing paradigms. This assumption is not supported by the present eye-tracking study. It investigates whether task-related selective attention is disrupted depending on the animation intensity of banner ads when users are in a search mode as well as the impact of banner animation on perceptual and memory performance. 相似文献
