Research on Image Completion Technology of Cartoon Image [PDF]
, 2015 图像修复是根据一定的规则对图像中的信息缺失的部分进行填充修复的算法，要求修复后的图像能够尽量与图像中原有的部分保持连续，平缓过渡。图像修复是图像处理中的一个重要课题，在破损照片修复、图像编辑、图像中物体移除等方面有广阔的应用前景。本文提出的图像修复算法是针对动漫图片的特点提出的，将图片中的待修复区域分为结构部分和非结构部分两大部分，然后分别根据它们的特点提出相应的修复方案，使得最后的修复结果能够保持原来图片的结构连通性，符合人眼的视觉习惯。算法可以分为动漫图片的结构信息提取算法 ...

Effect Assessment of Marine Ecological Restoration：A Case Study of Sansha Bay [PDF]
, 2016 由于人类对海洋资源的无序开发，海洋生态系统面临着环境恶化、结构失调、功能衰退等诸多问题，并逐渐制约海洋的可持续发展。海洋生态修复作为当前缓解生态系统退化压力、恢复受损生态系统结构功能的重要手段，是海洋生态系统管理的核心内容之一。但目前针对海洋生态修复的研究大多以针对单一生境的修复技术措施为主，缺乏对海洋生态系统各组分综合修复的系统研究，对如何评判海洋生态系统修复的效果，更是关注甚少。科学合理的对海洋生态修复实践进行评价，可以及时掌握生态系统对人工修复的响应和反馈 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Many existing rubrics for L2 argumentative writing prioritize form‐based linguistic accuracy and complexity while insufficiently addressing substantive argumentative rigor and effectiveness. This limitation is further complicated by cross‐cultural variation in rhetorical conventions and educational practices, which challenge the direct ...

The Resistance Research and Application of Typical Plants for Island Vegetation Restoration [PDF]
, 2016 植被是海岛生态系统的重要组成部分，海岛植被修复对加快恢复受损的海岛生态环境，改善海岛居民的生活生产条件起关键作用。目前，我国大部分海岛生态破坏比较严重，而海岛植被修复工作起步较晚，海岛植被修复技术还不完善，对环境恶劣海岛植被修复依然缺乏良策。本文依托平潭海岛景观生境修复技术研究与示范项目，以木麻黄（Casuarinaequisetifolia）、夹竹桃（Neriumindicum）和台湾相思（Acaciaconfusa）为实验材料，室内人为控制干旱胁迫、根系盐胁迫和叶片盐胁迫的程度及时间 ...

Resource Substitution: Local Governments' Issue Attention and Policy Reinvention
Policy Studies Journal, EarlyView.ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.

Mechanisms of Cadmium Tolerance and Detoxification in Sesuvium portulacastrum L. [PDF]
, 2016 近年来由于电镀业、化工业、采矿业蓬勃发展导致大量镉进入水体、大气、土壤环境中，造成严重的镉污染问题，严重威胁生物生命安全。目前镉污染问题已经成为当今世界共同关注的环境问题之一，植物修复法作为一种“绿色”的污染治理手段，由于具有低成本、高净化效率等优点，成为国际上的热点研究领域。目前，植物修复方法的应用越来越广泛，但仍存在很大的局限性，大部分超累积植物生物量少，修复效果不理想，且只能适用于低盐土壤或淡水水域修复，而能够用于盐碱地、湿地及海水水域等盐度较高区域重金属修复的相关植物较少 ...
