Converter steel - making is a complicated diverse high temperature reaction process and the foundation of the model also is a diverse non - linear mapped process . so it is emergent to find a more superior control model abandoned the tradition static model in the condition that many medium and small converter cannot use an assistant gun 转炉炼钢过程是一个复杂的多元多相高温反应过程，其模型的建立则是一个典型的多元非线性的映射过程，尤其在大多中小型转炉不宜增设副枪的条件下，如何在传统的静态模型之外寻找性能更优越的控制模型，就显得比较突出和迫切。

There is way too much going on in this file to explain it all in this short introductory article , but a few things are key to understanding how websphere ejb to rdb mapping works . it is not my intention to tell you how to generate this file from scratch , but instead to explain what it does so that you ll be able to make small changes to this file and the others we ve covered in order to handle simple challenges in cmp mappings with websphere 要在这篇短小的介绍性文章中全面解释这个文件，就要讲很多，但对于理解websphere ejb到rdb的映射工作，有几点很关键：我的目的并不是告诉您如何从头生成这个文件，而是想说明它做什么工作，这样您就能够对这个文件（和其它我们已讨论过的文件）做一些小的更改来应对使用websphere进行cmp映射过程中的简单问题。
Aiming at this problem , the main research issues and achievements in this paper are as follows : bi - directional data transformation between rdb and xml with semantic constraints preserved for most of existing researches on static data transformation between xml and rdb , dtd is taken as the schema description language for xml , and the semantic constraints are often lost during the transformation process . to overcome these disadvantages , the author adopts xml - schema , a standard schema description language proposed by w3c to replace dtd , as the description method owing to its more powerful functions than dtd , and of course with the syntax much more complicated . after analyzing the constraints characteristics in both xml - schema and relational schema , a semantic constraints - preserved algorithm is proposed which can realize the bi - directional schema mapping between rdb and xml through a formalized description of xml based on regular tree and a general expression for relational schema based on direct graph approach 保留语义约束的xml与rdb双向静态数据转换技术现有研究大多采用dtd ( documenttypedefinition ，文档类型定义)作为xml的模式描述语言，并且在模式映射过程中丢失语义约束信息，本文分析了xml - schema ( xml - schema采用与dtd完全不同的语法，数据描述能力更强同时也更为复杂，已被w3c确定为替代dtd作为xml模式描述语言的标准)及关系模式的语义约束特征，通过基于正则树的xml形式化描述方法以及基于有向图的一般关系模式表示方法的研究，建立保留语义约束的xml - schema与关系模式的双向模式映射算法，实现了xml与rdb的双向数据转换，较好地解决了xml与rdb在静态数据转换层面的数据集成问题，可有效满足企业大量rdb数据面向xml的发布以及与日俱增的xml数据存入rdb的应用需求。
