1.调用库函数节点（加法）

实现功率信号谱的测量，功能丰富，可测性较强，能够实现复杂功能(Achieve power signal spectrum measurement, feature-rich, testability strong, complex functions can be achieved)

一些常用的LabVIEW小程序，自己写的时候可以做一些参考(Some common LabVIEW small program, write your own when you can do some reference)

说明：  基于labview的串口通信程序，可通过串口向下位机发送不同的指令(The serial communication program based on LabVIEW can send different instructions to the lower computer through the serial port)

LabView中UDP通讯，通过IP地址与端口号可以进行单机或局域网内多台计算机之间的信息通讯。(LabView UDP traffic by IP address and port number to the communication of information between multiple computers in stand-alone or LAN.)

在波形Graph显件上用两种不同颜色显示一条正弦曲线和一条余弦曲线，每 条曲线长度为128个点，其中正弦曲线的x0 =0，△x=1；余弦曲线的x0 =2， △x=5。并利用属性节点通过前面板控件改变每条曲线的颜色。 ①一个周期128点。 ②改变颜色一定要先选择曲线，然后再改变颜色。(A sine curve and a cosine curve are displayed in two different colors on the waveform Graph display. The length of the bar curve is 128 points, where the sine curve x0 =0, Delta x=1, the cosine curve x0 =2, Delta x=5. And use the attribute node to change the color of each curve through the front panel control. One cycle is 128 points. Change the color must first choose the curve, then change the color.)

该vi主要是一台简单的单通道数字示波器，实现数据采集、波形显示、信号处理、波形存储等(The main vi is a simple single-channel digital oscilloscope, data acquisition, waveform display, signal processing, waveform storage, etc.)

函数发生器，各种常规的波形发生，以及数据的存储和数据导入功能！(Function generator, a variety of conventional waveform generation, and data storage and data import capabilities!)

用于实验室高效液相色谱的分析,简化分析过程(be uesd for analysis of high liquid )

说明：  labview很重要的例程，适用于labview新手(it is very important for the new student of labview ,very usful)

数据采集卡采集拉力值，与预先设定的拉力值进行比较，然后PID运算，控制相应的PWM占空比输出，最终控制电机的速度(The data acquisition card collects the pull value and compares it with the pre-set pull value. Then the PID arithmetic is used to control the output of the corresponding PWM duty cycle, and finally the speed of the motor is controlled.)
