说明：  labview FX-3U modbus通信(labview FX-3U communication)

示波器的设计，基本上满足日常的使用。可以自动调整频率等功能(Design of Oscilloscope)

VISA module 2 for serial communication

该程序可用于控制keithley2600数字源表测量太阳电池的IV曲线。可设置正反扫描次数，实时显示测量结果，并计算Jsc，Voc，FF，eff等电池参数。程序IVnew是总程序，除子程序外，还包括NI公司网站上提供的keithley2600程序包（必要）。(The program can be used to control keithley2600 digital source meter to measure the solar cell IV curve. Can be set to the number of positive and negative scanning, real-time display of measurement results, and calculate the cell parameters of Jsc, Voc, FF, eff. The program ‘IVnew’is the final program.)

1. 一个完整数据采集系统的基本组成部分 2. NI 提供了基于哪些平台的数据采集硬件产品，它们分别适用于什么样的应用领域 3. 数据采集设备硬件选型过程中应该关注哪些重要参数(Introduction of NI data acquisition hardware 1. Basic components of a complete data acquisition system 2. NI provides data acquisition hardware products based on which platforms and which application areas they are suitable for respectively. 3. What important parameters should be paid attention to in the process of hardware selection of data acquisition equipment)

说明：  该程序主要实现了，在labview中远程访问数据库的功能。(it can help us to query the database on line.)

说明：  视觉图像处理图片二值化基于labview，简单易懂谢谢参考(Visual image processing image binarization based on LabVIEW, easy to understand, thank you for your reference)

基于Labview的电子钢琴设计，通过对声音频率的设置，实现发声及演奏功能(Labview-based electronic piano design, set to the frequency of the sound, vocal and performance features)

歪度指标是描述信号概率密度函数的重要参数。在对非平稳信号进行时域分析时，利用歪度指标反映了振动信号的非对称性，用来判断轴承是否发生碰磨。本文件中将歪度指标独立制作了子VI，便于labview程序调用。(The skewness index is an important parameter to describe the probability density function of a signal. When the non-stationary signals are analyzed in time domain, the skewness index is used to reflect the asymmetry of the vibration signals, which is used to judge whether the bearings have been touched or not. This document will be independent of the index made a sub VI, easy for LabVIEW program calls.)
