The present invention relates to a novel process for converting the intermediate in the synthesis of atorvastatin having the following formula or atorvastatin lactose into the non-crystalline atorvastatin calcium: wherein A denotes a common protection group or separate protection groups for the dihydroxy group and B denotes a carboxylic acid protection group.

本发明涉及一种将具有下式的阿托伐他汀合成中的中间体或阿托伐他汀乳糖转化为非结晶阿托伐他汀钙的新方法：其中A表示二羟基的共同保护基或单独保护基，而B表示羧酸保护基。

The main works of this paper include four points as follows:(1) Patent retrieval domain ontology is designed through analyzing the common concepts in searching patent information. And the international patent classification table is expressed using ontology;(2) Design users'interests model from the information actively provided by users and passively provided by system based on users'requirements and historical searching record;(3) Design and implement three patent retrieval modes: quick search, table search, and advance search to meet various users'demands. And combine ontology, user's interest model and the inputed retrieval condition when users search for patent informations. This realizes individualized retrieval which meets the demands of users;(4) When users's search term is inaccurate, the precision will drop markedly and users will receive many disrelated informations.

本文的主要工作包括以下四点：(1)通过分析专利检索的常用概念，设计了专利检索领域本体和国际专利分类表(International Patent Classification，IPC)的本体表示；(2)根据用户的需求以及历史检索记录，从用户主动提供和系统被动学习两方面着手，设计了用户兴趣模型的本体表示；(3)为满足不同层次、不同需求的用户，设计并实现了三种专利检索方式：快速检索、表格检索、高级检索，并将本体、用户兴趣模型、用户输入的检索条件三者相结合，实现满足用户需求的个性化检索；(4)通过设计将检索结果按IPC号分类，由用户自主选择需要浏览的类别来为用户提供个性化服务。

HAVANA - Cuban President Fidel Castro on Wednesday led a patriotic homage to the father of shipwreck survivor Elian Gonzalez -- saying the 6-year-old boy's return last week was the most emotional moment of his revolutionary life .

This means that, in most cases, only a very small part of an object will lie within this area. If we want to observe the object in detail, we have to move the fixation point frequently to make the different parts of the object lie within the central area. In addition, with such a small central area, the separation of foveal and peripheral channel becomes meaningless. Consider all the above aspects, we propose in this thesis a visual computing model based on selective attention mechanism.

针对上述问题，本文的模型引入选择注意机制，并将之建立在非均匀采样表示与处理的基础上，我们提出了一种可以随视觉任务变化的可变结构的非均匀采样信息表示方法，并通过它将后继的视觉处理分成相对独立的中央和周边通道，分别完成对感兴趣物体的识别和注意点的快速转移，后者相当于对感兴趣物体的一个粗定位过程。

For such complex and composite systems as analogue and digital systems, electronic and mechanical systems, the Ptolemy II attain purposes with heterogeneously hierarchical ideology, in other words, actors and model of computation at the same level stand for a behavior of the system, and these components at this level can be converted into a composite actor that stands for another behavior of the system under the control of different models of computation at upper level with other actors. In this way, the system may be structured hierarchically.

对于复杂的混合系统，如模拟与数字系统，电子与机械系统，Ptolemy II采用层次异构的思想实现，即同层的角色和计算模型表示系统的一种行为，而这一层组件又可转变为一个复合角色，在上一层与其它角色在不同的计算模型控制下表示系统的另一种行为，从而实现系统的层次构架。
