Labview计算时间间隔的代码，精确到微妙，简单好用

LabVIEW开发技术丛书 深入浅出统计过程控制 序言——献给初入质量管理的工程师 谈质量管理，不得不说现在最成功和应用最广泛的6 西格玛管理。参加6 西格玛管理培训的人很容易就坠入统计学的云雾中，每天置身于大量数据的统计分析和报表中，彷佛6 西格玛管理就是做大量的统计分析和报表。 悲哀啊，真的是悲哀~~！这让我想起儿时学习数学的时候，繁多的家庭作业，让我每天置身于大量的计算中，让我感觉数学就是计算，就是大量繁琐的公式，就是大量的背诵和记忆。(LabVIEW Development Technical Series Layman Statistical Process Control Preamble- dedicated engineers entering the Quality Management Talk about the quality of management, have to say that the most successful and most widely used Six Sigma management. Participate in Six Sigma management training, it is very easy to fall into the statistical clouds, daily exposure to a large number of statistical analysis and reporting of data, as if Six Sigma is to do a lot of statistical analysis and reporting. Ah sad, really sad ~~! It reminds me of childhood when learning mathematics, many of homework, let me exposure to a large number of calculations every day, so I feel that the mathematical calculations, is a lot of complicated formulas, is a lot of memorization.)

labview应变信号采集储存显示。采用Dll连接设备，采集信号，有采集储存显示调零及回放功能。(labview strain signal acquisition and store display. Using the the Dll connection equipment, signal acquisition, collection storage to zero and playback capabilities.)

基于labview程序开发平台开发的动态信号分析软件，分析软件包含多个分析子程序，整个程序可以采集和分析4个通道的数据。分析功能包含fft，时间波形等，可设置多个采集参数，采样率，采样长度和窗函数。通道参数设置包含传感器类型和耦合方式/灵敏度等参数。

利用事件结构实现一个密码登录框，当用户输入密码是123456时弹出“密码正确登陆成功”对话框，单击“确定”按钮后程序停止。若密码输入错误，则弹出“密码错误请重新输入”对话框，单击确定按钮后程序继续运行。密码可修改。

说明：  用labview实现图像的二值化，通过把图片转化为二维数组，通过和阈值比较把图像二值化(Achieved with labview binary image by the image into a two-dimensional array, and the threshold value by comparison to image binarization)

基于labview的闹钟程序，可以显示当前时间并设定某个时间闹钟。(Labview-based alarm clock program that can display the current time and set a time alarm.)

调幅波的解调过程(不失真地还原信息)通常称为检波，同步检波器用于对载波被抑止的双边带或单边带信号进行解调。它的特点是必须外加一个频率和相位都与被抑止的载波相同的电压，同步检波器的名称由此而来。 本程序采用同步检波器进行解调
