• Jsp , xml and celts ( chinese e - learning technology standardization ) are the main three necessary techniques to development this model . the xml - based metadata system model can facilitate learning object resources retrieval , reuse and exchange
  从技术实现上，系统模型采用了三层的体系结构，主要实现技术是jsp 、 xml 、学习资源对象元数据技术和celts体系规范。
• In this thesis , we study the properties and development of the proton - exchange membrane and focus on the status and defects of the typical polyperfluorosulfonic acid membrane , of which high cost is the most obstacles for the commerce of the fuel celt
  本文论述了质子交换膜的特点及其发展方向，重点阐述了全氟磺酸型质子交换膜及其在燃料电池应用中存在的问题。针对这些问题，我们对质子交换膜进行了探索性的研究。
• At last the paper uses fully learning data according celts , constructs theory and methord of implementing system . the theory has two aspects : gives imprecise learning methords using rules when sequencing initially , such as introducing , narrating emphases and so on ; during the process of learning , we construct a fuzzy evaluating model using the data of scores , learning time and browsing times , and adjust scores with learning objects . then we can inference more precice learning strategy based on the result of evaluation , such as searching previous knowledge units , learning current knowledge units repeatly
  该原理主要体现在两个方面：一是在初始编列时，根据规则的匹配与调用可以实现较为粗略的教学方法指导，如一般性介绍、重点讲述等；二是在过程导学当中，针对最具代表性的测验成绩、学习时间、浏览次数的学习效果和行为，结合学习者的预期学习目标等因素进行适当的成绩调整、时间改进等处理，并运用模糊综合评判的方法对学习者实施有效评价，以推理出在学习过程中较为细化的教学建议，如搜索前驱知识单元、重新学习当前知识单元等。
• With the requirement for the quality of learning online , individual learning is necessary direction . during the process of researching it intelligent tutoring system base on web ( wits ) is a important problem . this paper at first introduces and analyses its ' s development , traditional system structure , then gives a framework of wits based on celts
  计算机于教育方面的应用自最初的计算机辅助教学( cai )到现在已经历了近半个世纪，随着人们对网上学习质量和效率的要求日渐提高，个性化的网络教与学是其发展的必然，在这其中，网络智能授导系统的研究是一个重要的课题。
• Furthermore , this paper presents a courseware standardization model based on xml . faced with so many nonstandard courseware , this model which aims at attaining the two criteria , i . e . ims and celts , makes full use of xml technology to realize courseware resource standardization from two aspects , i . e . courseware resource meta - data and content packaging
  在此基础上本文提出了一种基于xml的课件资源规范化模型，该模型以ims celts规范为目标，针对目前大量存在的非标准课件，充分利用xml技术，分别从课件资源元数据标识和课件内容包装两个方面来实现课件资源的规范化。
• Individual learning and wits are relate with computer science , education , psychology and other subjects . because of their difficulty the actual application maybe need a longtime research . this paper integrates celts into them , makes good attampt on how to implementing the practicality and generality of wits
  个性化学习和网络智能授导系统是一个融合了计算机科学、教育学、心理学等学科领域的综合性研究课题，由于其自身的复杂性，对其的真正实际应用还是一个长期的探索过程。
• This paper examines two major criteria of distance learning , i . e . ims ( instructional management system ) and celts ( chinese e - learning technology standardization ) . in addition , it discusses the two important mechanism of ims celts - learning resource meta - data and content packaging and how to realize courseware sharing and reuse based on these two mechanism . next , the paper studies the drawbacks of the present courseware , and indicates that it must comply with ims celts for the realization of courseware sharing and reuse
  本文研究了远程教育领域的主要规范ims （ instructionalmanagementsystem ）和celts （ chinesee - learningtechnologystandardization ） ，探讨了ims celts的两个重要机制：学习对象元数据和内容包装，以及如何通过该机制实现课件共享与重用，分析了传统课件存在的缺点，指出要实现课件的共享与互换，就必须遵循ims celts规范。
