事务

On base of SG, Evaluating function could be used to decide that which transaction should be aborted.

并在此基础上根据评价函数对事务评价，从而选择合适的事务回滚。

The features of transaction in multidatabase systems are analyzed, and the necessity to keep the global serializability when concurrency control of transaction processing in multidatabases is emphasized.

分析了多数据库系统中事务的特征，指出多数据库事务处理的并发控制问题需保持全局可串行化，即要求在各局部场地局部事务的执行不违反全局的执行次序。

The extended transactions are executed by the LDBMS on the local database and the specially generated control tables. These extended transactions are responsible for the global serializability and recovery of transactions.

局部数据库管理系统在局部数据库和控制表之上执行扩展事务，这些扩展事务负责维护全局可串行性及事务的恢复。

It is true, he was never employed in the latter, the numerous family he had to educate and the straitness of his Circumstances keeping him close to his trade: but I remember well his being frequently visited by leading men, who consulted him for his opinion in public affairs, and those of the church he belonged to, and who showed a great respect for his judgment and advice: he was also much consulted by private persons about their affairs when any difficulty occurred, and frequently chosen an arbitrator between contending parties.

公共事务，他从未服务过，负担这个人口众多的家庭，这种窘迫的环境把他束缚在商业上；但我很清楚的记得常有领袖人物来拜访，他们征询他对于镇上事务的意见，或是关于他所进的教会内，他们对于他的审判和忠告甚为佩服，他也常和外人筹划他们的事务，若遇有困难时，便被推选为双方争吵的调解人。

Firstly the properties of L-MAX frequent itemsets is analysed.Then by extending FP-tree structure an ExFP-tree data structure is presented and the algorithm of ExFP-tree generated is given.According to the character of prefixing paths shared in FP-tree,ExFP-tree implements compressingly storage of transaction information with sharing the transaction information of descendant nodes.

ExFP-tree利用FP-tree共享前缀路径的性质通过共享子孙节点事务信息策略实现大量事务信息的压缩存储；最后基于FP-MAX算法，提出基于ExFP-tree的L-MAX频繁项集挖掘算法，核心思想是先根据L-MAX频繁项集长度约束性质进行前瞻剪枝再进行最大频繁项集挖掘，并通过回溯策略直接定位生成对应事务集。

It discusses the premise,conflictive concept,basis style,task as well as content of built on those of this pattern.

本文认为，建立具有中国特色的地方监督，必须在我国宪政体制下完善地方监督的措施和手段，促进政府间权力的合理分配，区别国家事务和地方事务，增强政府间的相互信任，增加纠纷解决和专责地方事务的机构，明确地方首长的职责，修改相关法律，理顺财政关系，增强地方政府的回应能力，重新估价、继续坚持和发挥执政党的领导监督作用，重视社会监督产生的舆论力量，以此确立与该模型相适应的我国地方监督形态。

This paper puts forward the OLAM transaction optimizing and scheduling model, which take advantage of the strategy that the most valuable transaction preferentially are dealt with.

论文还给出了OLAM事务间的多种协作模型，提出了&基于有效资源的事务价值最大最优先的OLAM事务调度策略&。

The study of this area has progressed correspondingly. However, some only discussed this topic theoretically, ignoring the practical aspects; others oversimplified the questions and measures, unsystematically and inaccurately.

目前关于大学生事务管理的研究也日渐丰富，但现在很多研究仅仅停留在大学生事务管理理论层面，另有一些对大学生事务管理面临的问题和对策的研究比较宽泛，浅尝辄止，研究还不够全面、系统。

Traditional concurrency control methods constrain the concurrency of transactions and are disadvantageous to satisfaction of Real-Time transactions' timing constraints. We develop a novel quasi-consistent serializable concurrency control strategy. The inconsistency brought by transactions to the system was restricted to an extent.

传统的并发控制策略限制了事务执行的并发度，对实时事务定时限制的满足是不利的，我们开发了一种适合于实时应用环境的新颖的&准一致性可串行化&并发控制方法，事务给系统带来的不一致程度被限定在一定范围内。

Notice in particular that some lock modes are self-conflicting (for example, an ACCESS EXCLUSIVE lock cannot be held by more than one transaction at a time) while others are not self-conflicting (for example, an ACCESS SHARE lock can be held by multiple transactions).

请特别注意有些锁模式是自冲突的（比如，在任意时刻 ACCESS EXCLUSIVE 模式就不能够被多个事务拥有）而其它地都不是自冲突的（比如，ACCESS SHARE 可以被多个事务持有）。一旦请求到了某种锁，那么该锁模式将持续到事务结束。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
