形式化

Finally, the strict formal analysis is made for ZDB protocol(1999) proposed by Zhou et al. With this new method, as a result there exists 2 possible attacks in the ZDB protocol under non-secrecy channels: leakiness of secret information and reply attacks.

最后本文用新方法对Zhou等人(1999)提出的 ZDB协议进行了严格的形式化分析，结果发现该协议在非保密通道下存在两个可能的攻击：保密信息泄露和重放攻击。

This paper provides a complete and formal description for basic case retrieval network which is put forward by Lenz and Burkhard, establishes its mathematical model and then makes an extension for it.

本文对由Lenz与Burkhard提出的基本案例检索网络给出了完整的、形式化的描述，基于这种描述建立起数学模型，进而对其进行扩展。

In word processing, a program for producing form letters in which a name and address file is merged with the text file containing the letter.

在字处理技术中，用于产生形式化的信件的一种程序，这种信件是把含有姓名和地址的文件与含有信件正文的文件合并而成的。

In order to describe the dynamic and complicated process model exactly, we propose the logic situation calculus based on the expanding the situation calculus and describe the virtual enterprise in this formal logic framework.

为了准确地描述虚拟企业这种动态的、复杂的建模过程，我们对情景演算这种形式化逻辑框架进行扩展，提出了逻辑情景演算，并以逻辑情景演算来描述虚拟企业的运作过程。

This thesis studies the constructing and running processes of the virtual enterprise and proposes the virtual enterprise ontology oriented to the process modeling. It also represents the process model decomposed hierarchically described by logic situation calculus based on the virtual enterprise ontology and presents the corresponding organization model decomposed hierarchically for the virtual enterprise in the dynamic allying process.

本文主要通过对虚拟企业的结盟、构建和运作过程的深入研究，提出了面向过程建模的虚拟企业本体论，并在该本体论基础上，以逻辑情景演算形式化地描述了虚拟企业在结盟过程中逐步精化的过程模型，并建立了相应的虚拟企业分层递解组织模型。

In the meantime, we also can change the status of the logic situations and describe the allying process and cooperative process. In addition, we represent the virtual enterprise ontology in the formal logic situation calculus and can define the core elements more accurately. It maintains the consistency and integrality of the ontology. Accordingly, the process model based on the ontology will have strong reusability, accessibility and consistency.

相应地，我们可通过逻辑情景演算这种形式化逻辑框架来表示虚拟企业本体论，以支持虚拟企业本体论中核心术语的更精确定义，维持其一致性和完整性；进而，构建于该本体论之上的虚拟企业过程模型就具有很强的重用性和可访问性，并能够保持建模过程的一致性。

A formal model of PASCAL process blueprint,graphical notations of abstract logic structure diagram, and a fundamental programming procedure...

The synchronization problem in the distributed multimedia system is studied in this paper. The basic concept and convention about formalized stand language LOTOS are introduced,and the language is improved and extended by adding discrete time domain and time operator for establishment of its syntactic and semantic rules.

就分布式多媒体系统DMS中同步问题进行了分析与探讨，首先论述了形式化规范语言LOTOS的约定与基本概念，然后对其进行了基于时间的扩充，引入时间操作算子，确定了相应的语法定义和语义规则。

Firstly, the basic concept and convention about formalized stand language LOTOS is introduced, and, the language was improved and extended by adding discrete time domain and time operator to confirm its syntax and semantics rules.

本文首先论述了形式化规范语言 L OTOS的基本概念与约定，对其进行了基于时间的改进和扩充，引入了离散时间域和时间操作算子，然后确定其相应的语法定义和语义规则，通过仔细分析分布式环境下的多媒体同步问题，基于时间扩充的 L OTOS，给出了一种特殊的多媒体同步系统以及具体的算法描述。

In order to guarantee the correction of the design of system, it needs to specify and verify it rigidly. The formal description and verification by use of LOTOS (language of temporal ordering specification) and ACTL are given out in this paper. These allow people to study, evaluate and define the dynamic behavior of current user interfaces.

为了保证系统设计的正确性，文章讨论了如何使用形式化描述语言LOTOS(language of temporal ordering specification)和基于动作的时序逻辑ACTL对系统进行描述与验证，这有利于人们对交互式用户界面的动态行为进行研究、评估与定义。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
