Most of the e-learning research topics focus on metadata of learning object. These studies extract useful information from metadata, and use them to organize the LOs. However, to understand the metadata is not enough to organize the multimedia-style LO in meaningful manner. The comprehensive multimedia-style LO is especially useful for mobile learners to choose what they really demanded. In order to attack the problem, this project uses multi-agent technique to develop a personalized hyper-seamless learning environment for managing LOs comprehensibly. Following that, the proposed environment coordinates two agents: Content Reorganize Agent, and Zone Agent to provide mobile learners the efficient multimedia-style learning experience. The CRA is responsible for reorganizing the discovered critical multimedia content by analyzing learner』s behavior and the multimedia』s annotation. The ZA is designed for terminal devices to monitor the learning behavior, and it sends the collected behaviors to CRA for evaluating. Moreover, the ZAs can communicate with each other, and they can self-organize as a group for sharing learning resources. Due to the cooperation of the two agents, the learning environment can give the properly multimedia-style LO for learners without bandwidth squandering. Finally, we expect this project can construct a comprehensive multimedia-style LO map for efficient personalized seamless learning.

中文摘要大多数的数位学习研究著重於如何利用学习物件的Metadata来组织管理学习物件，然而只透过Metadata仍旧无法有效管理多媒体形态之学习物件，多媒体学习物件的内容若能被了解，则学习者能正确的选择所需的学习内容，尤其是行动学习，能正确选择行动内容不但能减少频宽的浪费，亦能有效利用行动装置有限的资源，有鉴於此，本研究计画拟利用多重代理人机制发展个人化超无缝学习环境来管理内容可被理解之多媒体形态学习物件，在超无缝学习环境中Content Reorganize Agent 与Zone Agent 这两支代理人程式负责协调作业以提供高品质之行动学习经验，其中CRA所负责的工作为分析学习行为与学习物件之注解找出多媒体关键内容来重组具备学习主题之多媒体学习内容，而ZA为安装於学习装置端的代理人程式，其负责监督学生在学习过程中产生的行为，并将该资讯传回CRA以供分析，此外ZA与ZA之间具备自我群聚组织的能力，同一群组下的ZA可彼此共享所需的学习资源，透过CRA与ZA的合作，个人化超无缝学习环境能在不浪费网路频宽的前提下，提供正确且合适的多媒体学习物件给行动学习者，最后我们预期透过本计画的执行能够建立具备内容理解能力之学习物件模型，并利用此模型提供有效率的个人化无缝学习。

For getting useful and lively information, subscribers can choose a primary application and pick the interesting parts from other source applications. By using XML Object as the event container to encapsulate any types of the message, we achieve the flexibility of content definition, self-contained data description, and high portability. According to the content syndication profiles, the information from source applications will create relationship and all the matching and useful events in target XML Object will be sent to subscribers periodically. With attachment XML Object, the levelly text/multimedia contents from related source applications can be embedded into target XML Object.

The signal intensity characteristic of MRI associated with brain myelinization is helpful to differentiate the normal and abnormal brain maturation.Also,T1WI is much more useful in the detection of immature myelin and in monitoring of normal brain development in the first 6 months of life.On the other hand,T2WI is more useful after 6 months of life.

不同月龄段不同解剖部位正常脑髓鞘化具有各自MRI信号特征，有利于评判是否脑发育正常和患脑白质病，T1WI评估未成熟髓鞘较好，T2WI确定髓鞘是否成熟较好。

And as different degrees of industry were apt to give men possessions in different proportions, so this invention of money gave them the opportunity to continue and enlarge them: for supposing an island, separate from all possible commerce with the rest of the world, wherein there were but an hundred families, but there were sheep, horses and cows, with other useful animals, wholesome fruits, and land enough for corn for a hundred thousand times as many, but nothing in the island, either because of its commonness, or perishableness, fit to supply the place of money; what reason could any one have there to enlarge his possessions beyond the use of his family, and a plentiful supply to its consumption, either in what their own industry produced, or they could barter for like perishable, useful commodities, with others?

就像不同程度的勤劳会给人们不同数量的财产，货币的发明也给予了他们机会去保存和扩大货币。想象有这么一个岛屿，与世界其它地方的贸易完全隔绝，在那里只有一百户家庭，但是有绵羊，马和奶牛，和其它一些有用的兽禽和有益健康的果实，以及足够生产十万倍谷物的土地，可是，由于这些物品不是太过普遍就是易于腐烂，岛上竟没有一样东西适合做货币；在这种情况下，那里的任何人在超过他的家庭所需，以及通过自身的劳动生产或与他人物物交换一些类似的易腐的有用的日用品之外又有什么理性去扩充他的财产呢？

This method not only provides a useful tool for analyzing and quantifying the bisbibenzyls but also provides useful information on the phytochemical research of these bryophytes.

建立了一种有效的分析及测定不同苔类植物中双联苄类化合物的方法，并可为苔藓植物化学成分研究提供参考信息。

The shredding of agro-residues, such as corn stalk, straw, wood sawdust and other herbaceous biomass, were investigated in this dissertation. According to the machinery mechanics of shredding, the components, shearing strength and pressive strength of the biomass were analysed in theory, which played a critical role during the shredding process. And the powder was examined by Scanning Electron Microscopy. It was founded that shearing,splitting and grinding force were appropriate for shredding biomass. The results also showed that primary shredding was the bulk shredding model, which was mainly affected by shearing and splitting force, therefore the curly knife and the straight knife were useful; while the fine shredding was the surface shredding model, affected by splitting and grinding force, and the straight knife useful.

本文以农林废弃生物质为研究对象，结合机械力破碎基础理论，从影响其破碎的化学组分和剪切强度、抗压强度等力学角度进行了理论研究，并运用扫描显微镜对破碎产物的微观结构进行了实际分析，结合二者得出如下结论：最适合生物质的施力方式为剪切力、劈碎力和磨削力；生物质粗破碎为体积破碎，主要受剪切力和劈碎力作用，刀片宜设计成弯口刀和单面直刃刀；细破碎为表面破碎，主要受剪切力和磨削力作用，刀片宜设计成双面直刃刀。
