The paper is organized as follows. In chapter 2, we introduce some concepts about SEA, the abstract SEA model and the convergence definition of algorithm. In chapter 3, we describe firstly the evolution of PMA as an abstract stochastic process, and by characterizing axiomatically the properties of the fundamental selection and evolution operators, we conclude that PMA is essentially a kind of SEA.

本文结构安排如下：第二章介绍了模拟进化算法的一些基本概念、形式化随机过程描述以及收敛性定义；第三章对改进后的 PMA 各操作作了抽象定义，得到了 PMA 的形式化随机过程描述，并公理化地证明了各操作算子为选择或繁殖算子，从而得出 PMA本质上也是一种模拟进化算法；第四章先对选择算子特征数定义作了适当改进，并通过各进化算子的具体特征数指出，如果 PMA 不采取任何执行策略时，算法本身并不收敛。

Because the data categoricalness rules of architecture products are embodied in theCADM described by IDEF1X, the data categoricalness rules are directly established according to the relationship, which is described by the IDEF1X, among the data entity of CADM described by the IDEF1X. Then every item of data which is in the form of CADM criterion and stored in the database is checked according to the categoricalness rules, so that the data categoricalness of C~4ISR system architecture is executed.3. The verification methods of system accessibility based on CADM are studied.

2研究了基于CADM的数据完备性验证方法由于体系结构产品中数据元素的完备性规则已经完全表现在用IDEF1X描述的CADM模型中，所以论文根据IDEF1X对CADM数据实体之间关系的描述，直接建立了数据元素的完备性规则，然后根据完备性规则对以CADM规范存放在数据库中的每条数据进行检查，以此对C~4ISR系统体系结构数据进行完备性验证。

Compared to C〓, HardwareC and SpecC, SystemC can be expected to be the standard language for hardware/software co-design and co-simulation because SystemC has the great power on describing the hardware/software heterogeneous systems and it will continually develop and many virtual tools will appear under great support of many leading EDA vendors. For example, CoCentric SystemC Studio and Cocentric SystemC Complier are powerful tools provided now by the Synopsys Corporation.

相对于C〓，HardwareC和SpecC来说，SystemC的优势在于，其一它本身有很强大的软件／硬件描述功能，其二由于有众多公司的支持，它的描述功能不断增强，其三是与它相关的支持软件系统的不断推出，例如，Synopsys公司的模拟工具CoCentric SystemCStudio和硬件综合工具Cocentric SystemC Complier等。

One of them is that it is not decidable and the other is that all the task knowledge in it has to be defined on an abstract logic level so it can not describe the concrete attributes of tasks.

其中，计算逻辑属于交互计算理论[4]，进程代数主要描述进程之间的通信，属于并发计算理论，两者都不太适合描述主体之间的资源交互。

将所构造的逻辑系统应用于具有组织的多主体系统行为建模，建立了基于描述任务逻辑的多主体组织模型和建模框架，并且表明应用描述任务逻辑构造应用系统具有表达能力强、结构紧凑的特点。

In the former representation, if no restrictions are imposed on formulas, then there is no algorithm to realize the reasoning in the resulted knowledge base; in the latter representation, the reasoning in the ontology represented by the description logic is decidable, while in general, for mathematical knowledge described by the first order logic which contains the ontology represented by the description logic, there is no algorithm to realize its reasoning.

在前者的表示中，如果对公式不作任何限制，那么得到的知识库中的推理不是可算法化的；在后者的表示中，以描述逻辑描述的本体中的推理是可算法化的，而以本体为逻辑语言的一部分的一阶逻辑所表示的数学知识中的推理一般是不可算法化的。

The masses of N and Δ baryons are calculated based on the confining potential amended or not in chiral SU (3) quark model and three-body theory method. The results shown that amendment can improve some values, but the improvement is still not satisfactory and the quark model can described octet and decuplet well but excited baryons.

利用手征SU(3)夸克模型和三体理论方法，在考虑禁闭势带修正项和不带修正项两种情况下，计算了N和Δ重子质量。N和Δ重子谱的计算结果表明，增加修正项能改善一些计算值，但改善程度仍然不是很令人满意；SU(3)夸克模型能够很好描述重子的八重态和十重态，但不能很好地描述激发态的重子。

Petioles are often described as winged in Hemiboea; since a winged petiole is really a decurrent leaf blade, they are described here as the leaf blade base.

叶柄是在Hemiboea里描述成具翅的通常；自从一具翅的叶柄真的是一下延的叶片，他们已经把这里描述为叶片基部。
