说明：  本书是一本"围绕练习来学习”的图书，特别适合作为大专院校的实验教材或者是自学用书。全书涉及的内容除了LabVIEW的基本编程概念和方法之外，还有大量的章节讨论DAQ的使用及LabVIEW的应用。全书共分13章，内容包括while循环与波形图、for循环与波形图、MathScript模型与XY图、DAQ辅助数据采集、数据文件与字符串、移位寄存器、case结构、数据独立性与序列结构、vi分析、使用DAQmx vi的数据采集与生成、PID温度控制项目、独立仪器控制等。(This book is a "learning around practice" book, especially suitable for college experimental teaching materials or self-study books. In addition to the basic programming concepts and methods of LabVIEW, there are also a large number of chapters to discuss the use of DAQ and the application of LabVIEW. The book is divided into 13 chapters, including while loop and waveform diagram, for loop and waveform diagram, MathScript model and XY diagram, DAQ auxiliary data acquisition, data file and string, shift register, case structure, data independence and sequence structure, VI analysis, data acquisition and generation using daqmx VI, PID temperature control project, independent instrument control, etc.)

升压斩波电路（Boost）的仿真 针对 Boost 变换电路，完成以下工作： （1） 在 MATLAB/SIMULINK 下搭建 Buck 电路仿真模型，并设置好各个模块的参数； （2） 分别选择 3 个不同的占空比，用示波器同时观察 E，uGE，i1，io，uo 以及电感两 端的电压 uL和流过电容的电流 iL的波形（注意频率的选择）。(Boost simulation model is built under MATLAB / SIMULINK, and the parameters of each module are set up. (2) Choose three different duty cycles and simultaneously observe E, uGE, i1, io, uo and inductance with an oscilloscope. Voltage UL at End and Current iL Waveform through Capacitor (Attention to Frequency Selection)

运行环境：win―tc。 能实现一下功能： 1）从键盘读入数据，分析出一个单词。 2）返回单词种别（用整数表示）， 3）返回单词属性（不同的属性可以放在不同的全局变量中）。 输入数据例： 0 92+data> 0x3f 00 while 正确结果：这些单词的单词种别及其属性 INT10 0 INT10 92 + _ IDN data > _ INT16 63 INT8 0 WHILE _ -Operating environment: win-tc. To achieve some functions: 1) read from the keyboard data, analysis of a word. 2) to return to the word of other species (expressed by an integer), 3) the return of the word attribute (the attribute can be different in different global variables). Cases of input data: 0 92+ data> 0x3f 00 while the correct result: the word of these kinds of words and their properties do not INT10 0 INT10 92+ _ IDN data> _ INT16 63 INT8 0 WHILE _
