1.The related concepts on the hypertext technique and the goal of the Dexter model are introduced briefly,and three layers of the Dexter model are discussed in detail. The brief analysis and ?evaluation? of the Dexter model are also made. Some suggestions on the design of the hypertext systems based on the Dexter model are proposed as well.
首先给出了超文本的有关概念和设计Dexter模型的意义，然后详细讨论了Dexter模型的三层结构，最后对Dexter模型进行了简要分析与评价，并对基于Dexter模型的超文本系统的设计提出了若干建议
2.This l ink mechanism accords with the link character of open hypermedia system offered by OHSWG, and is compatible with the concepts in the Dexter reference model .
该链接机制符合开放超媒体工作组 (OHSWG)提出的开放超媒体中链的特征 ,并能与 Dexter参考模型中的概念保持一致 .
3.Methods The umbilical cord blood CD34 + cells were cultured in Dexter system in order to observe the biological behavior of adherent cells in vitro.
方法 分离人脐血CD34+ 细胞 ,采用Dexter法培养 ,对贴壁细胞进行观察和鉴定。
4.Objective To observe contineously on the cell surface molecule of Dexter culture of cord CD34 + cells in vitro.
目的 动态观察人脐血CD34+细胞Dexter基质细胞培养后细胞表面分子的变化情况。
5.Then discusses the application of the Dexter model in the system of the information r etrieval.
并讨论了将 Dexter模型应用于超文本检索系统中 ,使原文和倒排文件与超文本网络相对分离 ,并利用单汉字检索技术实现超文本的动态链接
6.To study the possibility of separation and culture of human umbilical cord blood adherent cell(HUCBAC), the umbilical cord blood CD34+ cells were cultured in Dexter system in order to evaluate and observe the biological beha- vior of adherent cells in vitro.
为了探讨人脐血贴壁细胞分离培养的可行性 ,分离人脐血CD34+ 细胞进行Dexter培养 ,观察贴壁细胞的生物学特点。
7.Issues for the design of a general architecture for cooperative hypermedia systems based onthe Dexter Hypertext Reference Model have been discussed.
论述了基于Dexter超文本标准模型的协同超媒体系统的通用体系结构设计中的问题。
8.The focus of this article is on the central object class of a Dexter-Based Hypermedia system:Links,Anchors and Components,and describes in details their structure,action and extendedform.
重点介绍了基于Dexter的超媒体系统中的几个重要对象类：链、锚和成员；
9.It is concluded that Forster mechanism is responsible for the energy transfer between rare earth ions in the gel glass doped with Eu-Tb-HFA-TPPO and Dexter mechanism is responsible for the energy transfer between rare earth ions in the gel glass doped with Eu-Tb-TFA-TPPO.
研究证实,前者稀土离子之间的传能为Forster传能,后者为Dexter传能。 Eu-Gd-HFA-TPPO掺杂的凝胶玻璃中,观测不到稀土离子间的敏化现象。
10.The critical distance R_0 for which concentration quenching will happen, and the interaction microparameter C_ Er-Er in tellurite glasses were determined on the basis of the energy migration model of Dexter theory. The value of C_ Er-Er in the proposed tellurite glass was compared with that in other glass hosts.
根据Dexter能量转移理论计算了Er3+在碲酸盐玻璃中发生浓度猝灭的临界距离R0及Er3+间相互作用参数CEr-Er,并与其他基质玻璃中CEr-Er数值进行了比较.
