队列

For a secretary to help handle the affairs of the company procedures, according to different jobs different priority level, Priority Queue is the application of a good example.

详细说明：一个用于帮助秘书处理公司事务的程序，可根据不同的职位确定不同的优先级，是优先级队列应用的一个很好的例子。

Workflow Engine is the core part of Workflow Management, this paper takes E- FSM as the model, consults the standards of WfMC, divides the Engine into five functional modules, adopts Distribute Object Computing technique of EJB、JMS、JNDI, control mechanism of thread polls and queue, script interpreter technique of BeanShell, and gives the design and implementation solution of each module,make it have the more obvious advantage in the application performance,resource utiliaztion,scalability,supporting heterogenicity and distribution.

工作流引擎是工作流管理系统的核心部件，本文以扩展的有限状态机为模型，参考WfMC标准，对工作流引擎的功能划分成五个模块，并采用EJB、JMS、JNDI等J2EE分布式计算技术和线程池、队列调度机制以及BeanSehll脚本解释技术等，给出了各个模块的设计和实现方案，使其在应用性能、资源利用率、可靠性、支持异构和分布性等方面均有较明显的优势。关键词扩展的有限状态机 EJB JMS 工作流引擎，线程池队列

Stratified, polycentric and prospective cohort study can avoid the shortcomings of randomized controlled trial and cohort study.

分层多中心前瞻性队列研究，可以避免随机对照试验的实施困难和队列研究控制偏倚差的缺点，可作为中医辨证论治临床疗效评价的一种探索性方法。

From the phalanx to the legion, from the tercio to l'ordre mixte, from the panzer division to fronts in echelon, conventional warfare has featured coherent formations, each trying to break the other.

从希腊方阵到罗马军团，从西班牙方阵（译注：由火枪兵和长枪兵混编而成的方阵，攻防兼备）到法国混合方阵（译注：拿破仑时代法军使用的一种阵形，战线正中的部队列横队，战线两侧的部队列纵队，这种阵形可以在战斗中形成持续而密集的射击火力），从装甲师到梯形锋面，传统战争中已经深深打上了阵形的烙印，两者的关系密不可分。

Furthermore, the mean cyclic period is emended considering that partial or all limited service queues are unstable.

并且 ，通过指出队列稳定性与模型稳定性之间的差异，给出了在部分或者全部的限定式服务队列不稳定时，模型的平均运行周期。

Forwarding information is obtained by label in MAC layer and is piggybacked in Request-acknowledgement frame. Clear to send handshake of the downstream node was triggered by RACK that made the data frame transmit consecutively across multi-hop.

在MAC层通过标签获取转发信息并携带在请求－应答帧中发送，触发下游节点的清除发送帧握手，使得数据包多跳连续转发；连续转发概率根据业务类型和节点数据包队列占用率确定，实现了区分服务，避免了节点队列溢出。

Through scheduling process analysis of periodic task, the waiting limit formula of each task in ready queue was obtained while guarantees its deadline. In addition, some properties, such as final preempting time was deduced and the necessary condition of periodic tasks preempting behavior was described quantitatively. Based on them, a micro scheduling preemption model for periodic tasks in ready queue was put forward, which decreased the number of preemptions and optimized system performance through changing the preempting sequences.

通过分析周期性任务的调度过程，得出在确保任务不错过截止期条件下，各个任务在就绪队列中可等待的最长期限计算公式，并根据公式推导出任务满足截止期的最后抢占时刻等属性，从而定量地刻画了周期性任务抢占行为发生的必要条件，提出了一套对周期性任务的就绪队列进行微调度的抢占模型，通过改变抢占关系来减少抢占次数、优化实时系统性能。

The message is placed into a special queue dead letter queue after five unsuccessful retries.

该消息被放置在一个特殊的队列死信队列五年后重试不成功。

Most message queueing systems have a configurable number of retries before the message is sent to the dead letter queue.

多数消息队列系统在消息被送到死信队列前可配置一定数量的重试。

In any case, the window procedure gets all the messages—both queued and nonqueued—for the window.

任何情况下，窗口消息处理程序都将获得窗口所有的消息--包括队列化的和非队列化的。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
