现代数据管理几乎都是以数据库作为其核心的，同时，现实世界中越来越多的应用要求对数据的"定时"存取和对"短暂有效"数据的存取，实际操作越来越趋于复杂，软件的设计也越来越复杂，数据库访问和处理的速度已经越来越重要了，实时数据库在这种情况下提了出来。

For the follow-up treatment.Software part want function that realize: Through interrupt service routine gather and come out regularly ECG signal, store among computer in the form of the binary scale; Data compress programme should realize to ECG signal pretreatment and compress of signal, Narrow the storing amount of the data, save the space; Case information management system realize patient information and heart telecommunication file of interest, Keep and in the data base, can show the ECG signal wave form at the screen of the computer directly data that gather. Andhas offered and type and report the single function.

软件部分所要实现的功能为：通过中断服务程序把心电信号定时采集出来，以二进制的形式存储在计算机中；数据压缩程序应实现对心电信号的预处理和压缩，缩小数据存储量，节省空间；病例信息管理系统实现患者个人信息和心电信息的存档，把采集的数据保存作数据库中，能够将心电波形直接显示在计算机屏幕上，并提供打印报告单的功能。

The chain between air valve operational rule and bed stratification is set up, which supplies the reliability for control decision-making of expert system. Expert control strategy is put forward based on the characteristic of jigging process in this article. Knowledge acquisition, knowledge expression, search method and reasoning mechanism are studied in the expert system. The rule-base is set up based on bed stratification status, bed mobility status, feed velocity, recording data on site, artificial float and sink test result.

本文根据跳汰过程的特点，提出了专家控制系统的构成框架，研究了分层过程控制专家系统的知识获取、知识的表示与检索方法及推理机制，并根据分层状态、床层松散状态、给料速度信息和现场运行记录及定时人工筛分浮沉结果进行推理，建立了专家系统规则库，给出了具体的风阀操作参数的调节方法。

In this paper it also introduces the software architecture of system. The programs adopt C language and use module design methods. The paper discusses several limitation functions, the design of serial commination program and the high precision PID operation.

本调节器的软件，采用C语言进行程序设计，文中论述了该装置的软件组成，详细介绍了设计中所采用的异步定时中断的模块化设计方案，介绍了几种限制功能的实现和串行通讯接口的设计、以及高精度的PID运算等功能。

The conditional symmetry instability is the intermediate process between the stable and instable states of the atmosphere. The evolution of the atmosphere from the stable to unstable state or from unstable to stable state comes through two stages. The convective-symmetric instability circulation is related with the state and type of the instability. When the conditional instability lies in the lower level and conditional symmetric instability in the upper level, the circulation will have vertical updrafts in the lower level and slantwise updrafts in the upper level. The release of conditional symmetric instability gives rise to a mesoscale rain belt.

结果表明：条件对称不稳定是大气稳定状态和条件不稳定状态之间的中间纽带，大气由稳定向不稳定或者由不稳定向稳定的演变均通过条件对称不稳定来实现；对流对称不稳定环流的形成与不稳定层的配置有关，当低层为条件不稳定而高层叠加深厚的条件对称不稳定时，对流对称不稳定环流低层出现垂直上升气流，高层出现范围较广的倾斜上升气流，对称不稳定能量释放产生中尺度云带。

The necessary consent of the Apostolic See may also be presumed when, as generally at the Council of Trent, the legates have personal instructions from the pope on each particular question coming up for decision, and act conformably, ie if they allow no decision to be taken unless the pope's consent has previously been obtained.

必要的同意使徒见也可能被推定时，一般在安理会的特伦特， legates有个人的指示，教宗对每个特定的问题来作决定，并采取行动conformably ，即他们是否允许没有决定要除非教宗的同意，以前已经取得的。

In addition, all these core modules conformably used the ACE interface while using thread operations, UDP communication, timer and other APIs closely related to the operating system, which improved the portability of code and solved the problem of cross-platform development of distributed system. Reliability guarantee layer and resource management module completed object-oriented interface design by using OMG's IDL language, which ensured the openness of the distributed system.

另外，所有核心模块在使用到线程操作、UDP通信和定时器等与操作系统密切相关的API时，统一使用了ACE的接口，提高了代码的可移植性，解决了分布式系统的跨平台开发问题；可靠性保证层和资源管理模块使用OMG的IDL语言完成面向对象的接口设计，保证了分布式系统的开放性。

Over the long term the sum of simple conservation measures would render larger restoration work superfluous - certainly the ideal case of maintenance but in fact nothing other than the service contract for the heating system or the washing machine.

如此一来，艺术作品的损害可以提早发现，细微的损坏可以由修复师每年定时修理而不须庞大的开销；长期下来，这些简单维护措施的累积效果，将使得大型的修复工作不复需要——当然这种保养合约与暖气系统或洗衣机的服务契约内容其实是相去不远的。

Based on the analysis of the improvement research into EOQ model,it points out the significance of lead time,and introduces lead time into the order model with vendor-purchaser cooperation.

通过对经济批量模型改进研究的分析，指出了提前期的重要性，并将其引入合作条件下的订货模型中，证明了在一个买方和一个卖方的两级供应链中，当市场需求稳定时，买卖双方通过合作协商可以确定一个合理的价格折扣范围，在此折扣范围内，合作能够使供应链上的买卖双方达到共赢。

Life. But the intrinsic way of the Internet by wire confines accessing and using of the network information.

然而，Internet固有的有线连接方式大大限制了人们对网络信息的访问和使用。

I have a strong persuasion that this is true .

我坚信这是正确的。
