针对烟机生产要求高可靠的特点，作者采取了基于可编程逻辑控制器的解决方案，利用可编程逻辑控制器的运行稳定和可靠的优点，由可编程控制器作为现场控制器和通信主站，负责生产控制和通信，由计算机操作站作为从站，负责数据的显示、记录、管理及参数调整。

Mathematics exercise solution thought process displays in:Recognition and understanding, association and exploration, appraisal and choice, operation and realization, promotion and consummation; Its thought characteristics display as integrity, radiation and astringency, goal consciousness, disorderly and ordering, non-logical and logicalization characteristic.

数学习题的求解的思维过程表现在：认识与理解、联想与探索、评价与选择、操作与实现、推广与完善；其思维特征表现为整体性、发散与收敛性、目标意识、无序与有序化、非逻辑与逻辑化特征。

In addition,with aview to ensuring safety of the database content and operation,this paper designs business logic applicable to symmetrical encipheringand irregular enciphering(ensuring cipher safety and avoiding secret divulging)and business logic used to defend Web attack in the form of DLL suitable to any Web and any application system or program.

另外，为了增加数据库的内容的安全和保证数据库操作的安全，分别设计了一套用于数据库内容对称密钥和散列加密(保证密码安全及避免由于密码相同而造成泄密现象)的业务逻辑，和防止Web攻击的业务逻辑，并于DLL的形式存在，可被任何一个Web服务引用，也可被任何一个应用系统或程序引用。

The PI controlling system with the ability of intelligent logic judging method, can decide to choose perfect controlling operations, according to the height of coal in the ball mill, entrance pressure and the exit temperature error, which can avoid to operate wrongly because of the inter-inference of different control.

带有智能逻辑判断功能的PID控制系统，采用智能逻辑判断方法，根据磨煤机入口负压及出口温度所处的偏差区域，确定应该采用的控制操作，可以有效地避免由于各控制过程之间的相互干扰而导致总体控制效果严重恶化甚至整个控制系统无法正常投入等问题。

When we operate all accessing databases in encapsulation at Data Access Layer by ActiveX DLL packages (DAL layer, Namely data access layer),and operate all business logic or transaction processings in encapsulations at Business Logic Layer ( BLL layer, namely business logic layer), ASP dynamic webpages are offered to the interface of user for Presentation Layer ( PL layer, Namely present layer).

使用ActiveX DLL组件将对数据库的存取操作全部封装在Data Access Layer层（简称DAL层，即数据存取层），将商业逻辑或事务处理全部封装在Business Logic Layer层（简称BLL层，即商业逻辑层），提供给使用者的界面就是Presentation Layer层的ASP动态网页。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
