Combined system simulation with optimal control, selected a typical water cooled primary/secondary chilled water system, used the research achievements of Annex 30 in IEA for the reference, this work firstly presents both the basic component models and the control system component models. Secondly gives the main models for parameter identification and experiment validation. Finally a dynamic digital simulator is set up using TRNSYS as the platform to substitute a real system to test and evaluate some kinds of online optimal supervisory control strategies after giving some essential data file input and finishing all the PID controllers'tuning.

本文将空调系统的仿真模拟与优化控制相结合，首先选择比较典型的水冷式二级泵集中空调系统，在国际能源组织IEA第30子课题Annex 30多年研究成果的基础上，建立了系统各设备的部件模型和控制系统部件模型，对主要模型参数的辨识方法进行分析，同时对其准确性给予验证；在此基础上，建立了以TRNSYS为仿真平台的集中空调水系统数字仿真器；通过必备数据文件的输入和对所有下位机控制回路PID参数的调试，最终完成可用于评估各种上位机优化控制方案的空调水系统数字仿真器。

This article uses HK-2000C integration numeral pulse sensor developed by HuaKe Electronic Technology Research Institute. It is used to collect pulse signal of subjects into computer and store them in data file. Designed the pulse signal collection system,time domain analysis system and frequency domain analysis system using LabVIEW software. 134 objects are taken, including 73 healthy person, 61 coronary disease and hypertension patients. Analysed the signal using time domain and frequency domain system, then compared each analysis method.

本文采用肥华科电子技术研究所研制的HK-2000C集成化数字脉搏传感器，将测试者的脉搏信号采集到计算机中，并且以数据文件格式存储应用labVIEW软件设计了脉搏信号的采集系统时域分析系统频域分析系统取检测对象134例，其中健康人73例，冠心病高血压患者61例将采集的信号进行时域频域分析，并对各种分析方法进行比较

Sometimes, over time, we have deleted a lot of paper, do not know what the restoration of a file, but in fact, under normal circumstances, we have first to restore the recent deleted files, this time into the system as long as the Recycle Bin, and Right-click the mouse, select "Arrange Icons","delete by date" command to delete the Recycle Bin will be in accordance with the date of the document will be deleted one by one order, this time you can quickly find the date according to the deletion of the file to restore the .

有时候，时间一长，我们删除的文件多了，就不知道该恢复哪一个文件了，其实，一般情况下，我们都要先恢复最近删除的文件，这时候只要进入系统的回收站，并右击鼠标，选择"排列图标""按删除日期"命令，回收站就会按照删除的日期先后将删除文件一一排列，这时候你就可以快速地根据删除的日期找到要恢复的文件了。

An encryption method based on ECC is applied on the MPEG system directly. The encryption method isnt considered the characteristic of the video signal, regard the image data file as the general binary scale data file to encrypt.

论文最后采用了置乱算法的加密思想，考虑到MPEG-2视频结构中P帧和B帧中运动向量计算的特点，提出了一种基于混沌理论的视频加密算法。

In personal computers it is the sequence that searches predetermined disks for a Command Interpreter program, then a Configure System file, and finally an Autoexecution Batch file.

个人电脑中，引导加载始终序列，搜索预定的磁盘中的命令解释程序，然后是配置系统文件，最后是自动执行批处理文件。

Some file systems, such as NTFS file system, support compression or encryption for individual files and directories.

一些文件系统，像NTFS文件系统，对于个别的文件或目录支持压缩或加密。

The program also has a file property extension for displaying all kinds of detailed information about a file or folders level of fragmentation on the system.

该计划还扩展名的文件属性显示的各种详细信息的文件或文件夹级别的分散的系统。

Paging and Registry file fragmentation can be one of the leading causes of performance degradation related to file fragmentation in a system.

另外 PageDefrag 也会显示系统档案在磁碟上的分散情况，如果碎片不是很严重的话就可以不用重整。

Specified file length was too large for the file system.

对于此文件系统，指定的文件长度太大。

The procedure is simulated using two disk directory structure of the file system file manipulation, it can be achieved on some basic document management, such as : read, write, delete files.

这个程序是模拟采用二级目录结构的磁盘文件系统中的文件操作，它可以实现对文件的一些基本管理，如：读、写、删除文件等。
