libView introduction 第五章，一本libview的入门级电子书(libView introduction)

说明：  计算1——n的平方和大于1000的n的最小值，并计算出累加和(Calculate the sum of squares of 1-N and the minimum value of N greater than 1000, and calculate the sum of accumulations.)

Labview双通道采集模拟电压，显示波形图并保存数据未TXT格式。(Labview Dual Channel Data Acquisition and Storage)

此范例说明 了在LABVIEW平台下进行船舶运动可视化仿真平台(This example illustrates the ship motion visualization simulation platform in LABVIEW platform)

基于labVIEW的最小二乘法算拟合正弦波计算相位(Calculated based on least squares fitting labVIEW calculated phase sine wave)

开机启动程序，能够实现从开机启动界面到主程序界面的转换。(start program，it can achieve the function that complete the transformation from start face to main program)

通过输入用户名和密码后登录，实现输入正确和错误提示、登录前禁用并灰显读取按钮、登录后启用读取按钮、读取并显示文本文件内容、加密程序框图查看操作。(By inputting user name and password and login, we can input correct and error prompts, disable and gray display the reading button before login, enable the reading button after login, read and display the contents of text files, and view the encrypted program block diagram.)

基于LABVIEW的虚拟频谱分析仪，可以对任意信号以及采集卡采集到的信号进行频域分析，同时还加入了时域分析，使功能更为强大。(LABVIEW-based virtual spectrum analyzer can be arbitrary signals and the signal acquisition card for frequency domain analysis, and also joined the time-domain analysis, so that more powerful.)

输控制协议（TCP，Transmission Control Protocol）是一种面向连接的、可靠的、基于字节流的传输层通信协议，由IETF的RFC 793定义。TCP旨在适应支持多网络应用的分层协议层次结构。(Transmission Control Protocol (TCP) is a connection-oriented, reliable, byte-stream-based transport layer communication protocol defined by IETF RFC 793. TCP aims at adapting to the hierarchical protocol structure supporting multi-network applications.)

LAbview采集风扇频率实现风扇转速显示，可以手自动控制风扇转速(LAbview collects fan frequency to display fan speed. It can automatically control fan speed by hand.)
