The traditional query tree optimization methods,parallel database optimization methods based on left linear trees and right linear trees,bushy trees,and operation of the forest,have their own pros and cons,they have been more in-depth and maturity of the study.The query optimization method based on multiple weighted tree has studied its model of parallel query plan,its complexity model of parallel query plan and query optimization algorithms.The semantic query method transforms an inquiry into one or several semantic equivalence inquiries then has to find and implement a strategy to achieve a better query.Agent-based parallel database query optimization using Multi-Agent technology to automatically search the integrity constraint conditions which are related to the determined query,there for,the efficiency between several relations' joins has been greatly improved.The parallel optimization algorithm,based on genetic algorithm which is suitable for multi-joins of cluster environment,has deeply studied the relations storage options,multi-joins query optimization and query processing and other key technologies based on cluster parallel database.

传统的查询树优化方法，即基于左线性树、右线性树、浓密树、操作森林的并行数据库查询优化方法，各有优劣，对其的研究比较深入、成熟；基于多重加权树的查询优化方法，研究了其并行查询计划模型、并行查询计划的复杂性模型和查询优化算法；语义查询优化方法将一个查询变换成一个或数个语义等价的查询，进而寻找并执行这些等价查询中具有较好实现策略的一个；基于Agent的并行数据库查询优化采用Multi-Agent技术自动查找与给定查询有关的完整性约束条件，使得多个关系间连接操作的效率得到很大的提高；基于遗传算法的并行优化算法，深入研究了基于机群并行数据库中关系存储的选择、多连接查询优化和查询处理等关键技术。

After introducing the AOP, there are components, system connectors, aspect connectors and constraints in architecture. The UML and ADL description of each model are given, and achieves the transform from semi-formal to formal model, and the model's refinement and verification, which provides a good foundation for the development of tools.

引入方面的软件体系结构是由构件、系统连接件、方面连接件以及约束构成的配置格局，不仅给出了体系结构中各元素的统一建模语言和体系结构描述语言的描述，实现体系结构模型从半形式化到形式化的转化，而且实现了模型的求精和验证，为各种工具的开发提供了一个良好的基础。

There were rope- ladder-like patterns capillary nets around seminiferous tubules in postnatal 3 and 12 months.

2l'少}抖1」龄fl1可见支持细胞间不典型的紧密连接，24月龄纸未见到紧密连接。

Most beam-column connections used in multi-story frames are semirigid joints.

半刚性连接是目前高层钢结构建筑中常用的一种梁柱连接形式。

To verify the empirical formula and understand clearly the static behavior of the composite connections, eight specimens were designed and tested to failure, of which four specimens were semirigid beam-to-column connections and others were rigid connections with different types of stiffening details.

检验经验公式和清楚的静态性能的综合连接，8个标本进行设计和测试失败，其中4个标本进行了抗震设计和其他设备连接着不同种类的刚性节点僵硬的细节。

The characteristics and influencing factor on the bearing capacity,rotational stiffness and ultimate rotatability of steel frames with different semirigid joints are discussed,based on the experimental result.

完全刚接和理想铰接虽然使得分析和设计过程大大简化，但实际结构中的连接形式并非单纯刚接或理想铰接，应是介于二者之间的一种半刚性连接。

It has been four hundred years since the note relation in semitone music been appeared, and it become a chords sequence favored by modern composers from subordination status in classical harmony.

内容提要：半音中音关系和弦连接从出现至今已有四百多年，从传统和声中的次要地位，到近现代成为一种作曲家喜爱的和弦序进，半音中音关系和弦连接是随着和声半音化的进程逐渐得到重视和运用的。

Direct Connection ~~Connects through infrared or a serial cable to a desktop computer.
