过程控制

ABSTRACT Intelligent Control is developed for the systems, control environments and control objects with uncertainty, and it is a formularization process with the complexity and fuzziness which usually has not the non-traditional mathematical functions without known algorithms.

智能控制是针对系统及其控制环境和任务的不确定性而提出来的，是含有复杂性、不确定性、模糊性且一般不存在已知算法的非传统数学公式化的过程。

The influences of forcecontolled finite element method and displacementcontrolled finite element method on soil free displacement field are compared.

计算结果表明，受力控制有限元法更符合施工过程；而位移控制有限元法则与实测值更接近。

The influence intensity of frothing agent consumption、collecting agent consumption and stirring time are also found by Orthogonal Test, the reason is analized, and this provide basis for the control of this flotation process.

同时通过正交试验找到了起泡剂、捕收剂、调浆时间对该煤泥浮选过程影响作用的强弱，本分析了产生该种现象的原因，这为该煤泥浮选过程的控制提供了依据。

The process of powder soution preparation operates each soution tank gade, they are bocked off. it coud assure the best reaction time invariabeness consistency of every soution tank, avoid any direct touch of prefabricated tank iquid storage tank, the automatic contro system ised with eve sensor, to gain the exactitude consistency. When the eve reaches ow, the soenoid vave open, the powder feeding started. Opposite, the eve reaches high, the circe process stop.

干粉溶液制备过程是通过各个溶液槽分级逐步完成的，溶液槽之间隔开，保证每个溶液槽内的最佳反应时间和恒定浓度，避免在预制槽和药液储存槽之间有任何直接通路，自动控制系统与储存槽上的液位控制器相连，一旦液位达到低位，触发进水电磁阀打开，干投机启动，投加量安装水量设定，以获得精确浓度，当液位达到最高点，此循环过程就停止，当然搅拌器还按设定时间继续工作。

In conclusion, the proposed approach has a simple form without Gauss distribution and is in a large application to the quality control of small batch production.

Therefore, the identification of grinding burn and wheel wear is of interest to the people in the field of machine manufacturing.

因此，寻求实用、可辨识的信号源，并应用工况监视与故障诊断的方法，把烧伤的零件在磨削过程中识别出来、并及时预报磨削过程中砂轮的磨损状况，是机械制造领域质量控制的重要课题之一，具有重要的工程意义。

To up the grossness factor, visitors can pump on levers at the vomit and burp machines for maximum effect.

为了让参观者充分了解人体呕吐和打嗝等过程，人们可以通过操纵"呕吐机"和"打嗝机"的控制杆将这些过程看个明白。

The ability to have networked I/O cards share data directly without hardwiring them together helps operators execute simple control at the device level – allowing them to control unique areas of a process, such as different sections of a conveyor – and lets central controllers concentrate on data gathering and other more advanced functions.

无需将它们连线在一起就可以是网络 I/O 插件直接共享数据的能力帮助操作人员在设备级上执行简单的控制，允许他们控制一个过程的独特区域，例如一个传送器上的不同部件，而且使中央控制器集中于数据采集和其他更多的高级功能。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
