使用电脑时一定会遇到文件操作问题，如果对大量文件执行复制、删除、更改文件名等操作，这些问题如果仅靠Windows操作系统提供的功能来解决，费时费力，本文就提出了一种用VC实现的对文件名进行劈批处理的方法，可以方便的实现对大量文件的操作。 -The use of the computer files will be the operational problems encountered, if a large number of documents on the implementation of copy, delete, change file names, such as the operation, which, if only to provide the functions of Windows operating system to address, time-consuming and laborious, this paper presents a use VC realize the cleavage of the file name for the batch method, you can easily realize a large number of documents on the operation.

】通过建立倒立摆系统的数学模型,应用状态反馈控制配置系统极点设计倒立摆系统的 控制器,实现其状态反馈,从而使倒立摆系统稳定工作。之后通过MA TLAB 软件中Simulink 工具对倒立摆的运动进行计算机仿真,仿真结果表明,所设计方法可使系统稳定工作并具有良 好的动静态性能-] Through the establishment of an inverted pendulum system mathematical model, the application of state feedback control design configuration of the system pole inverted pendulum system controller, to achieve its state-feedback, so that the work of the inverted pendulum system is stable. After the adoption of MA TLAB software Simulink tool for inverted pendulum movement of the computer simulation, simulation results show that the design work will enable the system is stable and has good static and dynamic performance

欢迎使用“PLC串口通信调试” 本软件主要用于PLC(或单片机)与计算机的串口通信调试。软件根据目前PLC常用的多种串行通信协议的特点设计，数据的输入、组织和显示方式灵活多样，便于使用和观察调试。 在编制计算机与PLC的串口通信程序时，由于计算机和可编程设备双方均需编制通信程序，调试时往往不知道是哪一方的程序出了问题。可以使用本软件调试PLC一侧的程序，调试正确后再调试计算机侧的程序。本软件为PLC串口通信程序的调试提供了便利。-Welcome to "PLC serial communications debugging" This software mainly used for PLC (or single-chip) and the computer s serial communication debugging. According to the current PLC software for a variety of common characteristics of serial communication protocol design, data input, organize, and display flexible, easy-to-use debugging and observation. In the preparation of the computer s serial communication with the PLC program, computers and programmable devices as a result of both procedures require the preparation of communication, debugging often do not know which side the procedure is a problem. Can use the software side of the PLC program debugging, testing the right side after the debugging of computer procedures. The software for the PLC seria
